I had sex with my step brother's young friend before training without him knowing.

With a mix of curiosity and nerves, Sarah slowly unlocked the door to her step-brother's room. She knew she shouldn't be doing this, but the temptation of his young friend Justin was too much to resist. As she tiptoed inside, she couldn't help but notice the faint scent of his cologne lingering in the air.Sarah closed the door behind her, her heart beating faster as she saw Justin lying on the bed, sprawled out in only his boxers. His smooth chest glistened with sweat, and there was a bulge in his underwear that betrayed his arousal.As if sensing her presence, Justin opened his eyes and locked them onto hers. There was a flash of desire in his eyes, and Sarah couldn't resist the urge to step closer. He pulled her down on top of him, their bodies pressing tightly together.
