Mike huffs as he stares up at his older sister, his cheeks pink as he sits in her lap. He was bored!
"Mike."
Mike groans in typical kid fashion, annoyed that she's even asking him if he wants to.
"I already said I wanna," he pouts, then squeaks as she pulls him closer, rubbing them together and drawing out a moan from each of them, Nancy's back now on the bed.
"Come on then, we have school tomorrow," she says, pushing her underwear down to show her neatly shaved mound.
Mike perks up, helping her pull them down and licking a stripe up her slit, her fingers tangling in his hair.
He's still pretty clumsy with it, just learning and all, but he has her moaning so he counts it as a win, licking faster, between her folds, over her hole, any place she'd taught him to go to please a girl.
"I-I'm close," she gasps as his clumsy fingers finally rub her aching clit furiously. "Mike!"
Her moan of his name has him going faster, licking up her juices as she cums on his tongue until her legs are shaking and she's trying to push his head away.
But… she keeps moaning and whimpers as he keeps going, getting her into overstimulation as her chest heaves and her eyes close, finally leaning into it.
"Mike," she whines, her fingers back and tightening in his hair. "O-Oh god- Mike-"
He hums in her pussy, setting her off into another moan, shaking as she's close to coming again.
"So good, Mikey, just a little more…"
Mike doubles his efforts the best he can until she's coming again on his tongue, her hand muffling a loud moan as he finally comes up for air.
"Did I do good?" he asks, panting.
"I… loved it," she pants out, then notices his squirming. "Need help?"
"Please."
