This was Graham Montague's final year at Hogwarts, and he still needed revenge on the twins who had stuck him in that vanishing cabinet for weeks. He had been watching them since the beginning of the year, and it didn't take him long to realize that they were oddly close to Harry Potter.

Had they not been dating the Gryffindor chasers, Montague would have been sure that they had a crush on Potter. Or perhaps they did, but Potter seemed straight saying as how he had dated Cho Chang the year before and was now looking at the twins' youngest sister. And honestly, he couldn't really blame the twins for their infatuation with Potter since the boy had beautiful green eyes, a slim build worthy of any twink, and was not only great at Quidditch but also rich with both the Black and Potter fortunes behind him.

Slowly, an idea came to mind. What if he permanently stole Potter out from under the twins' nose? While the Montague family were pure blooded, they were not part of the Sacred Twenty Eight nor were they rich or influential. They could have been were it not for his great-grandfather marrying a half-blood witch which was when the book was written, but that book was filled with inaccuracies anyway so there was no point in being bitter over it. Plus any children that Potter might have would be pure blooded if barely since his mother was a witch, even if she was a mudblood. So why not take Potter as his own?

So Montague's attention went from the twins to Potter, and it didn't take him long to realize that Potter was stalking Malfoy. 

It took him a bit longer to notice that the stalking was not due to a crush but because Potter was suspicious of Malfoy which was both good and bad. The longer he watched the sixth year boy, the more he wanted him for the sake of himself rather than out of revenge so he would not have been pleased that Potter liked someone else. However, it also meant that Potter was not interested in other boys like he had hoped, so he had his work cut out for him to research then brew a potion or do a ritual that would entrap Potter.

Being in seventh year and studying for NEWTs, it was easy to get a pass into the restricted section of the library. There, he skimmed through texts on all sorts of dark potions and spells until he found the combination he wanted. First, a very mild attractant potion keyed to himself to get Potter - or rather Harry, he should get used to calling him by that name in his head - to gradually feel friendship to let down his guard towards Graham so that Harry and his friends wouldn't sense anything was wrong unlike with love potions. And once Harry had his guard down, he would dose the Gryffindor with a fertility potion while and perform a bonding ritual while he took the boy's virginity and impregnated him at the same time. 

It took a while to sneak the attraction potion to Harry, but he managed to slip it into Harry's drink during the Slug Club's yule party. Harry had gone with Loony Lovegood which was a relief - it seemed like either the boy hadn't realized he was attracted to the youngest Weasley girl or he hadn't found the courage to ask her out. Graham had stayed at the castle over the winter break since he had heard that the Gryffindor normally did, but he found himself disappointed when he learned that the boy had gone home with the Weasleys and hoped that nothing would happen between Harry and Ginny.

Still, he spent that time brewing the rest of the potions he needed in peace, so it wasn't a complete disappointment.

Thankfully it seemed that nothing had happened since she was still dating Dean Thomas on their return. Graham waited until he could catch Harry alone in the charms corridor, then he finally pounced.

"Hey Potter," he greeted with a friendly smile. "Have a good holiday?"

Harry paused to look around in confusion thinking it couldn't possibly be him the older Slytherin was speaking with, but nobody was around. "Er, yeah," Harry replied without a hint of wariness which meant that Graham's potion was working. "Uh... Did you need something?"

"Well, I heard you taught a bunch of students Defense last year - even NEWT level spells," Graham replied. "I was hoping you could teach me the Patronus spell so I can get extra credit for my exams? I would pay you, of course."

Harry looked cute with his expression of indecisive confusion, and Montague knew he would not regret this at all. "I don't need money," Potter said with a shrug.

"How about a favor?" Graham quickly said before Harry could turn to leave. "I'll give you all my notes from my sixth year Charms and Transfiguration classes in return."

"Er, but you only want one spell so that wouldn't be fair."

Graham gave a grin he had been told was roguishly handsome. "A very advanced spell that most wixen cannot use," he pointing out, being as charming as possible. "I'll even tutor you if you need help in either class."

Harry nervously scrunched up his nose as he looked around the empty corridor again. "You were in the Inquisitorial Squad last year," he pointed out. "I'm pretty sure you don't like me."

Graham gave a casual shrug while he inwardly cringed. "My family made me join it," he lied. "I honestly didn't try to do much since I didn't like Umbitch, but she had a lot of influence in the ministry so my father insisted."

Harry blew out a breath and finally relaxed. "Only you?" he warily asked, and Graham nodded. "Well... Alright. You don't have to give me your notes though - don't you need them to study?"

"I can just make copies," Graham said, then he held out his hand and shook Harry's when it was accepted. "Thanks, mate. Where do you want to study at?"

"Well... I don't really want people to know so how about one of the classrooms on the fifth floor in the Ravenclaw tower? Nobody goes there and they are all abandoned."

"Sounds perfect," Graham replied. "Can we start tonight after dinner?"

"Sure," Harry agreed with a shrug. "You aren't so bad for a Slytherin."

Graham barked out a laugh. "Not all of us are like Malfoy," he playfully teased. "I'll see you later, Potter."

"Okay."

Once they separated, Graham sprinted to the fifth floor classrooms and picked the one furthest away from any foot traffic to clean up. It had years of dust and cobwebs, so it took several cleaning charms to get it up to snuff. They he used grey chalk that was nearly the same color as the walls and started writing the runes needed for the ritual he had picked out on all four walls and the ceiling itself. By the time he was done, dinner was halfway over and he barely made it in time to be able to eat a small meal.

His friends had wanted to know where he had been, but he managed to dodge the questions by saying that he was working on a project for Ancient Runes and had lost track of time. It was unusual behavior for him, but with it being a NEWT year they let it slide since something along those lines had happened to half of them already. Seventh year was difficult with the homework and the revisions that the teachers were constantly requiring, so they let him be when he said he was going to go back to finish up his project.

Graham left dinner while Harry was still chatting with his friends over the remains of treacle tart to go back to the classroom, and he carefully removed the potions he had made over the winter holidays from his bag and placed them in a drawer on the teacher's desk. Then he placed himself in a blind spot from the half-open door and waited for Harry to find the room.

"Montague?"

Graham heard Harry call out just as he stepped inside, and Graham sent a silent stunner at the boy. Harry barely had time to turn with an expression of surprise before the spell hit him and made him collapse onto the ground. He hurried forward to drag Harry all the way into the room, checked the corridor outside to make sure there was nobody else around, then spelled the door shut and warded it with silencing spells and a notice-me-not. Then he turned to the boy sprawled out on the ground.

"Finally," he breathed out. "Time to finish getting the room ready."

Graham had no intention of taking Harry on a cold, stone floor so he started transfiguring tables and chairs meant for students into a bed frame, mattress, bedding, and pillows. Once that was done, he included a wash stand which he filled with water for clean up afterwards, then he spelled the clothes off of Harry and levitated him onto the bed. After that, he went and fetched the potions he had hidden in the teacher's desk, then returned to the bed and fed Harry the male fertility potion first since it would take an hour to work.

Graham wasn't idle in the hour he had to wait. He activated the runes on the wall, then he chanted the required vows in Ancient Greek to prime up the ancient bonding ritual that was rarely used anymore. Firstly, it required both parties to be a virgin, secondly it required once of them to completely shed their family name for the other, and thirdly, it required conception to occur on the very first try. It wasn't something that was easily achieved in the past, and in modern days it was considered too barbaric to use unless there was only a female heir to the family that someone else was willing to marry into to keep the family name from dying out.

However with the potions he fed Potter and the fact that he had no problem with taking the Potter name, there was an exceptionally high chance it would succeed.

Once the runes were all softly glowing, Graham turned back to the bed to finally look over his future spouse. Harry had an average cock, maybe a little on the small side, lovely little pink nipples, but his milky skin was marred with some scarring. It wasn't too bad besides the odd one on his arm that looked like it had been impaled by a stake or something. Graham carefully grabbed Harry's arm to inspect it closer, wondered what caused that, then decided he could find out later and flipped Harry over onto his belly before piling a couple pillows under his hips to raise his ass up.

He then used the incarcerous spell to bind Harry's hands to the bed posts at the head of the bed so the boy wouldn't be able to escape, then he cast a lubrication charm on Harry's pink furl and pushed the thin neck of the second potion into it with an eager grin.

The second potion was a lust and self-lubrication potion. He planned to take all three of Harry's holes tonight to really deflower his bride-to-be. However, having watched and wanted Harry for months now, he planned to make sure the Gryffindor would be begging for him to fuck him and would be willing to do anything for his cock.

Graham watched Harry's sleeping form as he undressed himself, then he stroked his own eight inch cock a couple times to get it hard before he climbed up on the bed and spread the back of Harry's thighs apart so he could see if the male fertility potion had grown a cunt or not since after the preparation of everything, it had been over an hour.

The pink slit that met his gaze made him groan with need, and he let go so he could pull the empty bottle out of Harry's arse to replace it with his finger instead.

The inside of Harry's arse was slick, hot, and tight, and because of the potion his finger easily slid inside. He felt around the inside walls for a minute until he found a spot that felt different, and Harry gave a low moan when he began to stroke it. Graham also let out his own groan as his own cock began to leak with need, however he had a plan and he was going to stick to it.

It didn't take long for Harry to whine and start humping the pillow under his hips in junction with Graham's stroking, and when he saw Harry's balls begin to tighten up, he pulled his finger out and started massaging Harry's bubble butt as he moved to straddle the back of Harry's legs since Harry was close to waking. While the rest of the boy was slim, his arse and his thighs were very sexy no doubt due to all the Quidditch the boy played. He grinned when he heard Harry whine with need, but he waited until Harry settled down and went quiet before he pushed two fingers inside to stroke the boy's prostate. Harry loudly moaned, and he finally woke up.

"Ngh, don't stop," Harry said as he pushed his ass back, then he froze when he tried to move his arms and found he couldn't. "What?"

"Sshhh, I'll take good care of you, Harry," Graham coo'ed. "Just enjoy it."

Harry twisted with a panicked expression, and Graham crooked his fingers to gently dig into his prostate which made Harry choke out another moan. "M-montague?" Harry stuttered out. "What are you doing?"

"What's it look like?" Graham asked as he leered down at the Gryffindor who had started humping the pillow again. "I've wanted you for months and now I have you where I want you."

"You can't do this!" Harry protested, though it came out more like a whine. "L-let me go! I won't tell anyone if you let me go now!"

Graham ignored him to continue to stroke the spot, and when he saw Harry's balls begin to tighten to come again, he pulled out his fingers and started sliding around Harry's slick folds instead. "Are you sure that's what you want?" he asked as Harry cried out in frustration which turned into a choked sound when Graham found his hard little clit to rub. "You are so wet for me, baby."

"Montague~" Harry whined. "What did you do? What is that?!"

Graham leaned down to nuzzle the back of Harry's neck. "Call me Graham, Harry," Graham purred, ignoring his question. "Tell me you want to come and I'll let you."

"Never!" Harry cried out even though he was all but humping back Graham's fingers. "Stop!"

Graham kissed the back of Harry's neck as he dragged his fingers away from the clit and over the folds once more so he could begin exploring the new hole. Harry burst into tears as he sank a finger inside the delicate wet space, and he started feeling around there until he found the spongy part of the G-spot to rub.

"No, stop, please!" Harry begged even as he wiggled to spread his legs further apart even though they were pinned under Graham. "Stop! Why are you doing this?!"

"Because I like you," Graham said in between kisses and sucks on Harry's neck. "Because I want you. And I want to hear you beg for me to let you come."

Graham pulled out his finger and Harry let out a sob of frustration. "No!" Harry cried out, though this time it sounded needy so Graham was sure that Harry was beginning to break. "No! Please!"

"Please what?" Graham asked as he moved his slick fingers back towards Harry's butt to press two fingers inside. "Do you want to come, Harry?"

Harry let out a wordless shriek of frustration as he went still under him, and Graham began to play way his prostate. This time he left red marks where he sucked on Harry's neck, then he bit into the meaty part of Harry's shoulder as he pressed a third finger inside making Harry buck and cry out with pleasure. He knew that Harry was getting close again, so he pushed his fingers deeper inside, then he kept them there so that Harry could adjust to the stretch while he sucked on the spot he had just bitten down on.

"Fuck!" Harry swore as he squirmed and pushed his ass back for friction, but Graham moved with Harry so that Harry wouldn't get any relief. "Fuck! I hate you! I hate you!"

Graham gentled his mouth when Harry began to sob again and kissed his way up to Harry's ear. "Shhh, darling, just tell me you want to come and I'll let you come," he murmured in a gentle tone. "I just want to make you feel good. Tell me you want it, that you want me, and I promise I'll stop teasing you. I want you, Harry Potter."

"Voldemort put you up to this!" Harry sobbed. "I know he did!"

"I don't serve him, and I never will if you agree to be with me," Graham coo'ed. "Nobody in my family were Death Eaters, I swear it."

And that would be true enough. Voldemort never killed pregnant wixen. He normally didn't kill children, either, so why he tried to kill Harry had been a mystery to Graham's family who had only been sympathizers rather than Death Eaters, but if Harry died after he gave birth Montague wouldn't mind too much. He would have the fortune and an heir, and if Harry won the fight, then he would be married to the defeater of the Dark Lord which would mean Graham could go far in politics or in professional Quidditch - either one he chose. 

That was when he realized the plan had deviated from revenge on the twins, but Graham didn't mind that. He just had to get Harry to say yes for the ritual to work. As long as there was no love potion involved, magic would take it as consent.

"Liar," Harry denied, then moaned when Graham crooked his fingers to rub his prostate again. "Stop!"

"Not until you say yes," Graham silkily purred into Harry's ear, his warm breath making the smaller male shiver. "I'm not interested in You-Know-Who. I'm only interested in you."

"Why?" Harry whimpered, his voice cracking as he tried and failed not to hump the pillow. "I don't like you!"

"But I like you," Graham replied as he continued to rub that sweet spot, careful not to let his own dripping cock dig into Harry so that Harry wouldn't get intimidated by the size before he gave in. He was honestly surprised that Harry was still fighting him with the lust potion running through his veins. "I want to make you feel good, Harry. I love feeling you writhe under me, though I would rather have you crying with pleasure rather than frustration. I want to make you happy, make you feel loved and treasured, I promise."

"Not like this," Harry desperately whined. "What about dates?"

"You would have said no so I ambushed you like this to show you how serious I am about you," he coo'ed into Harry's ear, then he pulled his fingers out of Harry's arse to play with the slick folds while Harry let out a needy little sound that he immediately choked off. "I promise you all the dates. I'll take you anywhere you want to go. I'll take good care of you, Harry, so just say yes."

"What did you do? What are you touching?"

Graham hid his grin of triumph behind Harry when he realized Harry was ignorant about the meaning of having a pussy. "I want all your firsts, so I gave you a pussy," he said, hiding his glee and his cunning behind a half truth. "Don't worry, it isn't permanent. I thought it would be more fun this way. Want to see?"

"See what?" Harry asked, then he vehemently shook his head no. "Wait, no, I didn't ask for this!"

"I'll let you come once for free," Graham silkily promised as he started rubbing Harry's clit, then he shifted to put a knee between Harry's legs to force them open for better access. "You can pretend you don't want it, dear. We both know otherwise with how wet you are, though."

"I don't want it," Harry whined, then he buried his face in the pillow and spread his legs open further by sliding his knees up. Graham groaned as he shifted his other knee so that he was fully in between both legs, then he replaced his fingers with his cock to rub the head against Harry's clit which made Harry moan and push back.

"Good boy," Graham breathlessly praised, resisting the urge to just shove his cock inside either of the wet holes now fully available to him. "See how good it feels?"

Harry moaned into the pillow and began to rock back against Graham's cock. After all of the merciless teasing it didn't take Harry long at all to come, and Graham had to squeeze the base of his own cock so he didn't follow when juices squirted all over it. He distracted himself by peppering Harry's back with kisses, and when Harry went to close his legs, he grabbed the back of his thighs and kept them open as he kissed his way down.

"I'm just going to taste you," Graham said in between kisses. "But you won't be allowed to come again until you beg now."

"No, please stop!" Harry whimpered as he tried to squirm out of Graham's hold, but he was smaller and weaker than Graham was. "Please, let's just ah! No, that's dirty! Stop!"

Graham had reached Harry's sweet little arse and was eagerly licking his way into the back hole while he ignored Harry's renewed protests and stronger struggles. The self-lubrication potion made it taste the same as Harry's pussy did which he also gave a few licks to compare the taste to, and it didn't take nearly as long to have Harry rocking back against his mouth. Graham might not have gone all the way before, but he had eaten out several witches in the past so he was pretty well versed on how to satisfy Harry as he alternated between clit and arse until Harry was keening with need.

"Please, Montague!" Harry finally cried out. "Stop, please! Just... please I need more!"

Graham pulled back with a wet slurp and lick his lips a couple times. "Call me Graham, sweetling," he said, his voice husky with how turned on he was. "What do you need?"

"Graham," Harry sobbed out as he wiggled his butt. "I need to come, please!"

"I'll only let you come on my cock now, Harry," he teased, then leaned in to swipe his tongue over Harry's sensitive clit just to make him shudder. "Say you want my cock, Harry. Tell me yes, that you want me, that you want this."

Harry whimpered and shook his head no, so Graham leaned in to lazily swirl his tongue around Harry's clit a few times before he resumed his licking into Harry's arse while his fingers pressed into Harry's pussy to begin stretching it open.

"Yes, yes, I want you!" Harry cried out after another few minutes of pleasure-torture. "Please, please give me your cock! I need it!"

The runes on the walls and ceiling brightly flashed before shimmering soft light shot out and hit the two of them, but Harry with his head in one of the pillows didn't see it. Graham watched how it sank into both of their skin to make them lightly glow as he rubbing Harry's thighs to soothe him with quiet shushing sounds, then he shuffled forward and started rubbing Harry's clit with his cock. The light from the ritual converged to his cock and Harry's pussy as Harry's cries of pleasure got louder, then he slid his head up and sheathed himself in Harry's hot and wet pussy in one go.

Harry screamed as he came around Graham's cock, and Graham himself couldn't hold out. He thrust once, twice, then a third time before he was coming, and he made sure to grind his cock in so that his come went as deep as it could go. He had never come so hard in his life before, and he thought his vision had gone white with pleasure until he realized it was the final flash of the ritual showing that the ritual was a success. Now he just needed to make sure that Harry would be pregnant for the bond itself to form.

He collapsed on top of Harry's back, and they both panted hard. "Hurts," Harry grunted. "Ow. You're too big!"

"You still came," Graham snickered, but he still shifted his weight onto his elbows so he wasn't crushing Harry under him. He knew he probably should have been gentler entering Harry's pussy, but he had no patience by then so hadn't been able to help himself. Still, the lust potion was burning through Harry and he knew that Harry wouldn't know any better. "And I can tell you are still horny. You didn't get to come with your cock, did you."

"Untie me," came Harry's petulant demand. "My arms hurt, too."

Graham grabbed his wand from the edge of the bed, sat up and let his cock slide out, then he watched his come ooze out of Harry's pussy as he summoned the bottle of pepper-up he had brought along. He downed it, then he vanished the ropes tying Harry up and leaned forward to massage his arms when Harry brought them down with a groan.

"Flip onto your back and I'll kiss your pussy all better until you are screaming my name," Graham coo'ed, feeling more energized now that the potion he had taken had run its course. "Then we can go another round."

Harry scowled for a moment, but he obeyed and they both shifted around on the bed until Harry was on his back. Graham shifted the pillow under Harry's head and arse to make him more comfortable, then he got to work once more.

This time Harry was an eager participant. Graham put Harry's legs up on his shoulders to keep them raised, and Harry fisted Graham's hair and rolled his hips up as he mewled with pleasure. He had to wring two more orgasms out of Harry until Harry was too limp to do anything but take it, and that was when he pushed Harry's legs up into a mating press and lined his cock up with Harry's ass.

"Wait!" Harry began to protest, but Graham pressed in hard so his head popped in and Harry cried out in pain. "Take it out!"

"Shhh, it's just the tip," Graham soothed, enjoying how much tighter the new hole was. "Just relax, Harry. It will feel good soon."

"No, I want it out!" Harry sobbed. "It hurts!"

"I won't move, I promise," Graham lied. "Just relax and breathe. Get used to it. You already had three fingers in there, you just tensed up so of course it hurts. Remember how good it felt to have my fingers in there earlier?" Harry nodded as he covered his face with his hands to hide his tears. "Exactly, and I want to see you come with your cock this time. Just relax and I promise to take it slow."

Graham began stroking Harry's softening cock, and Harry's sobs slowly petered out as the lust/lubrication potion worked its magic. It took a few minutes, but finally Harry nodded and silently wiggled his arse to show he was ready, so Graham carefully sank in a little more before he paused to let Harry adjust. He kept up that pattern of stroking and slowly sinking his cock in until he was fully sheathed, then he grabbed Harry's wrists and pinned them above Harry's head in one hand so he could look down at his debauched bride.

"So beautiful," he said to the teary boy as he adjusted to Graham's cock in his ass, making him blush crimson. "Here, let's get your glasses off before they get dirtier or break."

Harry averted his eyes and tried to hide his face in his arm with a mortified sound when Graham plucked the glasses off, then he set them to the side and gently grasped Harry's chin so he could swoop down to kiss him. It took a bit of sucking and licking to coax the Gryffindor's mouth open, and then Graham was licking his way inside and groaning at the taste and the obvious inexperience of the other boy. He would have thought for sure that Harry had more experience kissing with all the people that had a crush on him, but apparently not. Not by the clumsy technique the other boy had that left both their mouths messy with drool and Harry gasping for air by the time Graham pulled back.

"So delicious," Graham purred, and Harry squeezed his eyes shut in embarrassment. "Ready, sweetheart? I'm not moving until you tell me to."

"Y-yeah," Harry squeaked out, then he wrapped his legs around Graham's waist and rolled his hips. "See? I'm fine."

Graham groaned, then he began to rock inside of Harry. He started slow and easy just to make sure he wasn't going to hurt Harry, and when the slide of his cock inside became smoother, he started making his thrusts longer. He experimented with his angles until he heard Harry gasp with pleasure, then he kept at that angle until Harry was moaning and writhing under him, his bright green eyes glazed with pleasure.

Graham leaned down and started kissing Harry as he picked up his pace, his own grunts of exertion and pleasure mingling with Harry's moans. When Harry began to come untouched, he grinned into the kiss, swiftly pulled out of Harry's arse, and thrust a couple times around his cunt until his cock sank all the way in. He pounded Harry's pussy hard while Harry cried from over stimulation under him, and when he came, he made sure to press against Harry's cervix so that his sperm had a better chance of entering Harry's womb. With the pepper up potion running through his system, Graham didn't need to slow down. He kept pounding hard into Harry until Harry came with his cunt again, and then the boy passed out which was perfect for Graham. He finished inside of Harry a third time, then he climbed off, conjured up a thick dildo, and plugged Harry's cunt up so that none of his come would escape.

After that, Graham conjured up a glass and filled it with water which he drained. Then he drained a second cup, and prepared a third cup for Harry for when he woke back up. Then he pointed his wand at Harry's belly and cast the quickening spell to hasten the fertilization process.

"Now, for the final hole," he said as he ran his thumb over Harry's bottom lip with a lewd grin. "And the final potion."

The final potion was a simple addiction potion. It wasn't illegal, it just made someone addicted to a flavor for a couple weeks. It was actually a potion to help children eat vegetables they didn't like by making them think it tasted good and want it, and it only worked on natural, non-magical sources. In this case, it would be the taste of his come which was all over his half hard cock. It came in a bottle that sprayed the potion similar to perfume, so he spritzed his cock a couple times before he moved Harry onto his side close to the edge of the bed so he could feed his cock into Harry's mouth.

At first, Harry was unresponsive, but it didn't take long for the potion to take effect. Harry unconsciously started swirling his tongue around, then he groaned and began to suck as his eyes slowly cracked open. It took Harry another minute to realize what he was doing, and Graham's cock began to grow harder when Harry didn't stop and just looked up at him with a blush of embarrassment as he sucked even harder. It wasn't until Graham's cock grew until it was poking the back of Harry's throat that Harry pulled back, and even then he only pulled back enough so that he wouldn't gag.

"Like that?" Graham coo'ed.

"Mhmm," Harry hummed around his cock.

The vibration felt good and Graham reached down to fist Harry's messy hair, and he started to shallowly fuck Harry's mouth. Harry seemed to pick up that Graham liked the humming, and he began to hum some more for Graham's benefit.

"Such a good boy," Graham groaned. "You want me to come in your mouth?"

Harry hummed out another sound of acknowledgement, so Graham let his head fall back as he continued to thrust into Harry's hot mouth. The boy couldn't kiss, but this was by far the best blowjob he had ever had. However, after coming three times, there was no way he was going to finish quickly and eventually Harry pulled back with a sad whine.

"Jaw 'urts," Harry apologetically slurred. 

"That's ok, darling," Graham soothed as he started stroking the other boy's dark hair. "Here, why don't you get on your hands and knees? I see you are hard again, so I'll fuck your ass so that you can come and finish in there since I haven't done that yet."

Harry nodded, then he eagerly rolled over and got up on his knees. He buried his face in the pillow and enticingly wiggled his ass which made Graham chuckle, and he got back on the bed and positioned himself behind Harry to finger his ass. It was still slick and loose, the rim soft from the earlier fucking, so he lined himself up and slowly sank in. Harry whimpered in pain, but he pushed his ass back so Graham didn't stop until all eight inches were buried inside of Harry.

"Feel so full," Harry groaned. "More than before. Is there... something in my uh... You know."

"Oh yes," Graham said as he covered Harry's back with his chest and gripped Harry's wrists to keep him in place. "It's a plug to make sure you get pregnant."

"What?!" Harry yelped, and despite the lust potion he started struggling to get away. However Graham had both weight and height on him, so Harry's struggles were in vain. "Get off me! What did you do to me?!"

Graham pulled his cock back a bit then thrust in hard at at the right angle to hit Harry's prostate which made him cry out. "You're mine, Harry," Graham said with a dark and possessive chuckle. "This whole thing was a bonding ritual and abortion is illegal in the wizarding world. You are carrying my baby now, and there is no reversing this. All it took was saying yes, and you did."

"I didn't know!" Harry cried out, but his next protest he was about to say was disrupted when Graham hit his prostate again. "No! Get off! Ahn~!"

Graham bit down on Harry's unmarked shoulder as he began pounding into the spot over and over, and all Harry could do was take it. The younger boy cried in pleasure and anger, and Graham enjoyed every sound he forced Harry to make. Harry tried to tell him to stop over and over, but it was ignored, and eventually Harry came all over the pillows under him and the extra tightness made Graham come inside of Harry's ass. Then he immediately flipped the insensate boy over and started sucking and licking on his cunt while he pinned Harry's legs up to his chest while Harry screamed his name over and over while yanking on his hair until his voice went hoarse.

It took almost an hour of eating Harry out to make the boy pliant, and once he was he sat him up and fed him some water before he pulled the plug out of Harry's cunt to fuck him there again. Barring his orgasms, Harry was unresponsive and his eyes were completely glazed over. Graham made sure to mark up his neck and chest with hickeys by the time he finished inside the boy, and without pulling out, he cast a pregnancy detection charm and grinned when it came out positive.

"Don't worry, Harry, I'm taking your name rather than having you take my name," he coo'ed as he stroked Harry's sweaty forehead. "I promise to take very good care of you, okay? Graham Potter sounds a lot better than Harry Montague, and once you graduate and the war is over, we can have whatever kind of wedding you would like. Take care of yourself, now. Remember that you have a baby in your belly to keep safe."

"You said it was temporary," Harry mumbled as he turned his face away from Graham, tears spilling out of his pretty eyes. "You lied to me."

"It is temporary," Graham said to reassure his new bride. "Your pussy will go away in a couple weeks, and there is a special charm that will painlessly open up your belly once the baby is ready to be born. The womb will disappear a couple weeks after that, and there will be no sign you were ever pregnant besides the pregnancy weight that I'm sure you will quickly shed... and the small breasts you will have to feed our baby with that lasts up to a year. Don't worry, you will come to love me. The bond will make sure of that. In a few more weeks, you will constantly be seeking my company, and you will never be sexually attracted to another person besides even under the influence of a potion."

"I hate you," Harry said as he rolled over onto his side to put his back to Graham. "Go away."

Graham didn't let the words hurt him - it wasn't like he was expecting any other reaction anyway. "For now you hate me, but you will come around," Graham shrugged, then he got out of the bed and went to the wash basin he had prepared earlier to clean himself up. "This weekend is a Hogsmeade weekend and you will come with me as my date. Remember, I've thrown my lot in with you, not You-Know-Who, so at least you know my feelings for you are real."

Harry ignored him, so Graham shrugged again and got dressed. He did pause to give the unresponsive Harry a kiss on the top of the head, then he left the room after casting a few more protection charms on the door for Harry's safety. 

Harry would come around. And when he did, Graham had a few more of the lust/lubrication potions to dose him with until he came around in bed as well. And whether or not Harry participated in the upcoming war, he highly doubted Harry would endanger his own child so there would be an heir at the very least. And he would help Harry survive to the best of his abilities without pissing off the Dark Lord so that he could survive the fallout of whichever side won.
