Chapter Text
Thanatos should not be doing this.
It was a privilege to sleep in the same bed as Zagreus. Hypnos is here too, like he often is, to his chagrin, but he's at least less of a nuisance sleeping than he is awake. Regardless, Zagreus. His dear little brother, so different from himself and his twin, and for whom he felt affection like he felt for no other.
The love he feels for Zagreus should have kept him from doing this. The desire he felt deep within his core was why he was.
Zagreus, sleeping soundly, chest rising and falling with soft little sighs, hair messy and unkempt...it was entirely too much for Thanatos to resist. It was easy, unbinding Zagreus' chiton and pulling the fabric away. A little more difficult was pulling his leggings down, but the sight was reward enough. Thanatos settled between Zagreus' bare legs, using two fingers to spread his pretty little pussy, from which protruded a flaming clit that burned brighter the more Thanatos worked his thumb over it. Oh, Zagreus was irresistible. More irresistible still was the sound he made when Thanatos sunk a finger into his cunt, sleeping but still pleasured.
Zagreus was wet, so wet despite being asleep. Thanatos wondered if it was his own ministrations, or if perhaps Zagreus was having a particularly good dream. Maybe he'd ask Hypnos to peak in on those dreams sometime, and relay back to him what he discovered. Did Zagreus dream of him? His older brother, his best friend, so different from himself, fingering his cunt and sucking his hard clit? He wouldn't need to dream of him, now, because that's exactly what Thanatos was doing. His tongue was burning in such a way that Thanatos thought he might get addicted to it, as well as to the sound Zagreus made when he curled his fingers upwards and abused his walls.
Unconsciously Zagreus has taken to biting down on his own thumb, trying even in his sleep to contain himself. Even so, his noises were becoming louder still, breathless gasps pitching higher and higher until finally his body snapped and he came, hard, Thanatos still relentlessly working his clit even as he gushed over his fingers and his chin. Thanatos pulled away, wiped his face with his clean hand, and brought the soaked one to grip his own cock through his leggings.
His gaze was hungry as he took in Zagreus' form--chest still heaving from the intensity of his unconscious orgasm, legs spread to accommodate Than between them, and the hand he'd been biting down on fallen to the pillow beside his head.
Thanatos needed more.
He worked his own leggings down, pinning his chiton away so he could palm at his cock unobstructed--just for a second, before he arranged Zagreus' hips on top of his lap just right that he could slide his cock against that wet warmth, no, so he could impulsively plunge it inside, violate him further than he had already. Thanatos nearly came just from the initial breach--Zagreus was hot, tight--Thanatos wondered if he'd ever taken anything larger than his fingers inside of himself. He knew Zagreus had definitely done that, having not-so-accidentally walked in on the young prince pleasuring himself, and then vanishing before he could be noticed. The memory spurs Thanatos further, gripping Zagreus' narrow hips, pulling him into his thrusts. If the way Zagreus sounded before was addictive, then the way he sounded now was intoxicating. High-pitched, breathless, moaning gasps and whines. If only Thanatos could find some way to capture the sound of it forever to play back at his leisure. Some way to capture the look on the prince's face, eyebrows knit together, eyelids glued with sleep, pretty cupid's bow lips parted. His hand was gripping the pillow beside his head, the other on top of his chest clenched in a fist. All it takes to make Thanatos cum is a soft little gasp of something that sounded like "more" from the sleeping prince, revealing that on some subconscious level, Zagreus was enjoying this.
Thanatos pulls out with a guttural (and silenced, lest he wake his twin) moan, cum splattering against Zagreus' abdomen. He would have come inside, but even drunk with lust he at least had the foresight that it'd be harder to clean his cum out of Zagreus than it would be to just wipe him down. Which he does now, using some spare fabric to wipe Zagreus clean before working his leggings back up and haphazardly pulling his chiton back into place. The guilt has already begun settling in his core where the desire had reigned just so shortly ago, but when he settles down at Zagreus' side to sleep and Zagreus turns toward him, cuddling into him on pure instinct, he knew he'd be desperate for another chance to do this again.
