He couldn’t put his finger on any singular factor, nor had he really noticed before, but she was beautiful, and sexy, and had that subtle hint of a wild side. As his eyes traveled across her form, he found himself getting lost. Her pose thrust her chest out just slightly where he could see the soft shape of her breasts with small bumps where her nipples kissed her shirt. He was never good with sizes but wagered they were each more than, what? A Handful? Just large enough where they would swing when she bent over or would allow a perfect bed to nestle his cock between-
Scottie’s face suddenly went red as he looked up, locking eyes with Hannah who held a knowing smile. She raised an eyebrow, he looked away.
“Third time today I caught you. Something I should know?” she asked swiveling her feet from beneath her to the floor, legs together. She scooted herself to the edge of her seat.
He couldn’t help but look down, right at her feet. Tiny, delicate toes with red nail polish. When did she paint her toenails? Her ankles were crossed together. Then his eyes traveled up her smooth, long legs. She used to be on the volleyball team. Pretty good player. He was always excited to see her in her uniform. In those way-too-short shorts that were strangely similar to the ones she wore now. As his eyes crept to her thighs, for a moment, Scottie was certain they parted.
Hannah leaned forward, resting an elbow on her knee and her chin in her hand. She locked onto his eyes, unblinking.
“Sco-tttie,” she sang. “Hey. You in there?”
Scottie blinked, shaking his spell as he turned to look at his sister. She seemed to hold his attention, sitting with patience, love, and radiating sexuality. Her hair wasn’t perfectly styled, just messy enough. Her makeup was light, accentuating her lips and eyes, though Scottie admitted it was unnecessary. Her shorts were just tight enough to define the curves of her hips, thighs, and ass, while her shirt hung so loose, it lured one’s eyes to her flesh hidden beneath.
“I… I need a moment,” he stammered and bolted to the bathroom praying to all the gods she couldn’t see the bulge in his pants.
At the sink, Scottie reached in and splashed cold water across his face, shocking his senses. He braced his hand on the counter, leaning forward and looking into the mirror. His skin glistened from the water as it still dribbled across his face. The redness of his cheek had gone, the cut on his lip almost unnoticeable. Looking himself in the eye, he shook his head.
“Get it together, Scottie,” he said.
His mind was in turmoil. This was Hannah. His sister. His partner in crime when they would sneak extra cookies from the kitchen pantry. His bunkmate when their family was less well off and lived in a meager two-bedroom. And even though their father takes credit for teaching him how to roller skate, it was Hannah who corrected all the bad habits he had learned from Dad. He shouldn’t lust for her of all people. He’s got to get this under control.
Scottie’s just overstimulated right now, that’s all. His sister isn’t oozing 100% pure, uncut sexuality; that’s Scottie projecting his bursting state of horniness on her. That had to be it. He’s never felt these feelings for her before. Technically speaking, those times he would sneak peeks of her in her bikinis shouldn’t count. He was a horny teenager and the sight of exposed female skin was something that would draw the attention of anyone. That’s no different than the time she left the changing room door slightly ajar at the mall. Or the time they were out of bath towels and she ran to her room covering herself with only washcloths. Or when… Turns out there were quite a few instances of near-nakedness, side boobs, booty shorts, yoga pants, and observations of her body stretching, bending, and flexing in various ways that got his blood pumping.
