I first saw it in a ig sauce account that has been banned. It's about a flat chested girl and her boyfriend. They're on the school gym (maybe the locker room?) where the boyfriend asks her to see her butt. They end up having sex and the boyfriend asks her why they didn't sex anymore, she says it's because she feels bad when he looks at her breasts. He then says the important thing is the person they're attached to, not the size. It was a really sweet vanilla, I hope someone knows it 🙂
