Scottie was beside himself in bliss, watching his sister bob up and down on his cock as she worshiped it, deliberately focusing on his pleasure as she lived out her fantasy. All of it was even more exemplified by the knowledge that she was getting off on sucking her own flavor off of him.
He shook his head in wonder at her, how her ass was raised up like she was in heat. How her tits brushed back and forth against his legs. How she would pinch a nipple and moan into his member. How she slurped and licked and kissed his cock. This side of his sister he never knew.
“Fuck, Hannah! You’re incredible.”
“Mm-hmmm,” she said, mouth full of her brother. Hearing her own name moaned on his lips increased the flood to her pussy. Without a thought, she lowered her hand to her sore and aching mound rubbing it gently as she bobbed her head.
Her own groan caught Scotties attention as he watched her play with herself. Then a thought hit him.
Both realities had focused on him, focused on his needs. He needed to return the favor.
“Get up here,” he said. “Let me do that for you.”
She pulled off her brother, and a small trail of saliva dripped from her lip which she wiped away.
“What?” she asked.
“Get your ass up here,” he said again.
“Scottie, I thought you were close.”
“I am,” he said. “But I want to make you cum first.”
“I already-“
“Hannah, get our sweet ass up here so I can lick that pussy.”
So commanding, so sure; who was this Scottie? She smiled, rose, and swiveled her body around, pivoting over his groin.
“Be gentle,” she said as she lifted her leg to pass over his head, fully exposing her vagina and ass to his view. She settled herself lower, his head fully straddled, and she leaned back down, taking him back into her mouth.
Scottie, in turn, savored the moment. He ran both his hands over her thighs, feeling the sudden ridge of her cheeks rise and swell. He cupped both, squeezing, massaging the globes of her ass in unison. Each swell would open and stretch the cleft of her groin, that sweet, soft spot of the inner thigh and pelvis just outside her labia. He dug his thumbs in on both sides, softly stretching her open, watching her pink lips part, covered in dew.
Her aroma was intoxicating.
Hannah grew even wetter, knowing she was on full display. So open and vulnerable, and she loved it. Yet, with all this stimulation, sibling rivalry kicked in. She’d be damned if he got her off first. She swirled her tongue and sucked, then drove him deep down her throat.
“Fuck!” Scottie moaned as the pleasure overtook him. If that’s how she wants to play…
He pulled her ass to his face and plunged his tongue inside her, tasting her on his tongue for the first time. Her muffled moans encouraged him, driving him as he used his mouth to survey her responses.
Together, bodies entwined in a taboo Yin and Yang, they both sucked and licked, blew and kissed each other in ways known only to the most intimate. Hannah moaned as Scottie groaned. Both savored the taste washing over their tongues, both wondering how the other sibling became so skilled at their task.
