While my parents were away, my older brother and his wife started taking care of me. My brother and his kind, beautiful, cheerful wife, Ai—she's the perfect sister-in-law. One night when my brother was out, Ai suddenly slipped into my futon and seduced me. Overwhelmed by the soft feel of her big tits, I couldn't hold back and creampie fucked her. Since then, she's been drawing me in deeper—bathing together, showing off sex with my brother, tempting me nonstop. And tonight, once again, she's going to let me creampie her bare.
