The day I visited my beloved girlfriend's house, I was greeted by her big-titted, ladylike older sister. She was very horny and took every small opportunity to seduce me. Although I truly care for my girlfriend, I couldn't resist this older sister's advances. With my girlfriend, we can only have sex using condoms, but her older sister allows bareback sex and even creampie. Even though my girlfriend was right nearby, the incredible sensation of being inside her sister bare felt too good, and I couldn't stop thrusting.
