Part 1: (sorry ended up typing a whole lot and reddit doesn’t like long posts)
TL;DR: my gf and I went to a friends party at an airbnb house, more like mansion. As we were getting drunk, I went off to the washroom leaving my gf and having an old classmate of her’s come up to her and flirt with her. She didnt exactly like his advances, he was a bit annoyed that he figured out she was taken. As I come back to her, she tells me what happens and we then left to find a bedroom to get naughty. Said old classmate followed us in, catching us in the act, seeing her fully naked and complimenting her as I have my fingers inside her. We somehow let him watch, and she was so turned on, she left him finger her, and fuck her. Larry asks when will they (my gf and him only) get to fuck again? To which my girlfriend said nope, clings on to me and drags me to the next bedroom over, locking the door.
On friday night my girlfriend(24f) and I (25m) went to a party, which her friend rented an airbnb for. It was a nice house, many bedrooms, washrooms, big living room and kitchen! Fancy mansion type deal.
