An old school friend [F]27 and her boyfriend [M] asked me [M]27 to watch them fuck

Calling her a friend is a push honestly. We were in the same media class after she joined my school for sixth form. We didn’t speak much in school but a couple of years ago I followed her on social media because she is crazy hot. I barely even use my account but she is so hot I was willing to follow a private account just in case there was a thirst trap or two on there. There was. I think she was single at the time. I liked a picture of her dog once but that was the only move I was capable of making. Her boyfriend is a man mountain. If I made my move and he was in the picture back then, he would have won. He’s from a more exotic part of Europe than me and his girlfriend but I haven’t been able to peg exactly where yet. We didn’t exactly talk much during the incident. I think he might be Spanish or Portuguese. For the sake of the story their names shall be Abbie and Diogo.
