I have a terrible memory so I decided to start keeping lists finally and I recall these 2 specific yaoi mangas, mostly specific scenes from them, that I read probably about 2 months ago. I scoured my history and couldn't find them for one reason or another so any help is appreciated!

The first if I recall started with one of the main boys having a crush on another boy at his school and was upset when he actually got a girlfriend. Probably because of that he started dating or just doing it with the other main character and eventually they wound up in the school library while the boy who got a girlfriend was doing it with her, specifically I think he was fingering her. So the two main boys did it too while watching them. I know this is a pretty short scene but I'm hoping it rings a bell to someone!

The second I can't remember much from either, but I believe the top was originally straight and eventually when the 2 main characters decide to start dating he winds up on a university club(?) trip somewhere. They have phone sex, maybe because the bottom was in the middle of jerking off when he called, and the next day the top ends up super drunk and almost does it with a girl on the trip. He realizes it isn't his boyfriend because she starts ah, using her chest, and he quickly ends it before it goes any further. When he comes back they almost have a fight but he makes it clear he realized it wasn't him because of her chest.

I'm happy to hear any help and thank you ahead of time!

Is the second one:
