This is 100% true and happened about 10 years ago(correction from similar post in another sub) Back in HS I went on a family trip with the girl I was in love with at the time. She was about 5’10 long brunette hair and an athletes body (incredible soccer player, so killer hips and ok tits). The longer we dated the more I realized how much of a closet freak she was as she maintained a very innocent good-girl rep in school. It was her family’s annual road trip to visit cousins one state over. Her whole family didn’t like me very much as I had a somewhat bad-guy reputation at school (and they were very religious people; family had 7 kids and they all went to church every Sunday). But we were only 18 and going to different colleges so they let it go. During the trip we had zero alone time due to cousins, aunts, and uncles always being around and I had been so fucking horny for her while being forced to share a room with her cousin’s lame ass BF. We got through it though and I actually had a pretty good time as I was trying to make the relationship work (it ended shortly after college began because we both started banging other people after just a few months of long-distance).
