"Which do you prefer, my sister's boobs or my boobs?" Basically, my girlfriend's older sister, who doesn't wear a bra, puts a plump J-cup in close contact with my body. I was fascinated by the feeling of those big beautiful breasts. "If my sister finds out, it's over." I feel so comfortable that my girlfriend is right next to me and I can't stop swinging my hips and suck on my huge breasts. When she experiences titty fucking and hugging that she can't do with her small breasts... the erection stops!
