I finally got a girlfriend! But (crying) the girl next door suddenly changed and started attacking me. I wanted to have my first experience with my beloved girlfriend, but the big-breasted girl forced herself on me and I discovered an incredible pleasure... I love her, but the more I feel guilty and immoral, the more I remember those gigantic breasts... I want to do it with my sister! I want to do it with a big-breasted girl! I can't get excited or get an erection unless it's a big-breasted girl!! A new guilt-induced erection project!
