It had been a long week at school for Jack, and he couldn't wait to relax at home. As soon as he walked in, he was hit with the sweet scent of lavender, his step-sister's favorite aroma. He followed it to the living room where she was in the middle of a yoga routine. He watched in awe as she contorted her young, toned body, the thin fabric of her tank top and shorts revealing curves he never knew existed.
Their parents were away for the weekend, leaving them alone. Jack couldn't resist any longer; he crept up behind her and gently massaged her shoulders. She let out a soft moan, unaware it was her step-brother. He moved closer, his hardening cock pressing against her back. She moaned louder this time, her body arching towards him unintentionally.
