– Horny College Boy Is Turned On By His 18yo Stepsisters Ass During Yoga Ses

The sun streamed through the large windows of the yoga studio, illuminating the sculpted bodies of the students as they flowed through their poses. Among them was Ethan, a college freshman who had taken up yoga to improve his flexibility and strength. As he moved into downward dog, he couldn’t help but notice the girl next to him – his 18 year old stepsister, Liam.

Liam had only recently turned 18, but she had developed a strong, lithe figure. Her long legs stretched out behind her as she maintained a perfect plank pose, her toned ass sticking up in the air. Ethan felt a twinge of desire as he gazed at her, memories of late night fantasies coming back to him.

As the class progressed, Liam’s moves became more sensual and fluid. In lotus pose, she leaned back slightly, her pert breasts straining against her thin tank top. In half-moon pose, her tight-as drum yoga pants hugged her curves just right, the loose fabric riding up to reveal a tantalizing glimpse of her firm ass cheeks.

Sweat trickled down Liam’s brow as she transitioned into camel pose, her back arched and head thrown back. Ethan felt his cock begin to stiffen in his pants, straining against the confines of skin tight yoga pants. He shifted in his space mat, trying to hide his growing erection.

The next pose was child’s pose and Ethan welcomed the opportunity to take a moment and regain his composure. He knelt down and leaned forward, resting his forehead on the mat. Unfortunately, Liam did the same, and in the process her ass was squared up with Ethan’s face. She adjusted her position, and her ass cheeks brushed against Ethan’s chin ever so lightly.

The light graze of Liam’s ass was enough to send jolts of electricity through Ethan’s body. He felt his cock strain against his pants again, now fully erect and throbbing with desire. The rest of the class seemed to blend into the background as all he could focus on was Liam’s pert behind and the thin strip of fabric covering his stepsister’s most private area.

As yoga class drew to a close, Liam rolled up her mat and turned to Ethan. “Great class huh?” she asked innocently, totally unaware of the effect she had on him.

Ethan gulped and tried to act normal. “Yeah, it was a good one. How about you, did you like it?” He hoped his face didn’t betray his growing infatuation.

“I really did! I think yoga will end up being my new after school activity. Wanna grab some water and cool down?”

Ethan readily agreed. As they walked to the water cooler, Liam’s ass swayed enticingly in front of him. He couldn’t take his eyes off her round cheeks in those tight pants. He imagined what they must look like bare, and what it would feel like to grab handful of her firm ass and give it a squeeze.

Liam poured them each a glass of water and they sat down on a nearby bench. Ethan gulped his down greedily, hoping the cool liquid would ease the heat in his crotch. It was of no avail though, as his mind continued to conjure up naughty images of his stepsister naked.

The two of them chatted about their classes and school, but all the while Ethan fought the urge to slide his hands up Liam’s bare legs and under the fabric of her yoga pants. He wanted to feel her naked ass in his palms, to grind his growing erection against her plump cheeks.

Ethan shifted awkwardly on the bench, trying not to noticeably adjust his raging hard on. “Alright well, I better get going” Liam said as she finished her water and set down her yogurt mat. “Maybe I’ll see you in class next week?”

“Definitely, I’ll be here!” Ethan replied quickly. As Liam turned to leave, Ethan couldn’t resist ogling her ass one more time. He watched the rippling globes of her cheeks as she bounced out of the studio door, hips swaying.

Once Ethan was alone, he couldn’t hold back any longer. He quickly unzipped his yoga pants and pulled out his throbbing cock. As he stroked himself, he pictured Liam naked and in all kinds of naughty yoga poses – lotus with her legs spread wide, camel with tits dangling, even downward dog with her ass up in the air just begging to be penetrated.

Ethan groaned as he rubbed his hard shaft faster, imagining his rigid cock sliding into Liam’s tight, wet pussy from behind. He pictured pounding into his sexy stepsister as she moaned and bucked her hips back onto his. The naughty scene playing through his mind and the thought of her naked, lithe body was enough to send Ethan over the edge. With a muffled cry, he came hard into his own hand, fantasizing about his-Now that fantasy was slowly becoming his 18-year-old’s reality, as their sordid affair deepened. Ethan’s cock began to grow hard again at the thought of Liam sucking him off later.
