Steamy scene between siblings

"Zack?" Taylor wheezed, not meeting his eyes. She had to admit, Zack had such a nice tool at his disposal. Not too obscenely wide and at a comfortable length, Taylor prayed that his self-esteem remained guarded against ridiculous claims from locker room banter and the internet. Guys were way too obsessed with their penises -- she made that the point of her final presentation in her developmental psychology course, "Who Are the Real Victims of Penis Envy?" -- and the peer pressure to perform had extensive roots in the male ego. (Not that women were much better -- that was Hannah's presentation, "Tits, Sluts, and the Normalization of Misogynistic Behavior" -- and both made the case that humans are terrible. They got A's.) All the more reason that Zack needed helpful guidance. As his big sister, it was her responsibility.

"So... where are your pants?" she asked, manufacturing a reason for her gawking.

"Uh, I think in the kitchen," he answered rather matter-of-factly.

"I take it you didn't need them for a bit." His cock had a telltale sheen spread across it, and she had to smile.

"No." He returned it, almost sheepishly, with his head down.

Taylor twisted away from the door, gently closing it. She rolled onto the wall, keeping her gaze trained on her sweet brother. She still tickled herself, and made no attempt to end that now. It was his turn to blatantly gawk.

She snaked her free hand behind her back, and tugged the zipper of her top. Taylor hated having to bother her other hand from its job, but as the top parted, it had to past both arms. She replaced it immediately, but, she hoped anyway, a teachable moment would proffer something more substantial soon.

Zack shuffled forward, drawn to her bra-clad... assets like moths to a bug zapper. Taylor splayed herself against the wall, free arm held high, ready to accept him.

"Can I ask who?" she whispered, hearing the pounding blood rushed past her ears as he overtook her.

He grinned again, counting freckles on her chest. "Well... Ashley."

Taylor upped the tempo of her hand. Her breathing started to fray, unraveling into uneven gasps. "And Brandon let you? I can't believe that."

"They... broke up earlier..." Zack hovered over her silken lips.

"You're too fast, Zacky." His admirable length grazed her inner thigh, and a subtle shift of her legs brought her jeans to the floor, as well as a more prolonged touch. "You have to slow... down... and savor the moment. That's what girls like."

"Taylor..." His voice dropped below his everyday baritone, blue eyes blazing like a gas fire. She silenced him with a finger to the lips.

"Shhh, bro. Let me take you by the hand," she said as she did, sliding it to her waist, "and guide you."

His sister's soft lips landed on his own, and he was lost in a world he never imagined before.
