"Which do you like better, my sister's breasts or mine?" My body is tightly pressed against the ample J-cups of her sister, who basically doesn't wear a bra. I, captivated by the feel of those big, beautiful breasts... end up having an affair at her beck and call. "If my sister finds out, it's over." Even though my girlfriend is right next to me, I can't stop my hips from moving because it feels so good, and I devour her huge breasts. Once I experience titty fucking and the feeling of holding her that I can't with my girlfriend's small breasts... I can't stop getting hard!
