The time I[M] slept with my friends gf after an intense argument

One Saturday night while chilling at a friend’s house, about 6 of us drinking, playing some Kings Cup. It wasn’t too long before one of the guys suggested we play never have I ever. The issue with that was there were only 2 of us that were single. I tried to change it to like truth or dare, the lesser of the two evils. Trying to delay the inevitable we the girls urged us to play Never Have I Ever. It started a fun, small things like I’ve never been arrested, ditched school, the innocent things while trying to feel out how far you can go. My friend “Sue” had said that she never swallowed, the other two girls drank. Her bf “Sean” laughed and asked if that’s why she goes to the restroom after she gives him oral. She said yeah. I had said I’ve never been in a 3way. My other bud “Rob” asked if it counts if they started but stopped because one of them fell asleep. I said sure and Rob and Sue both drank. Sean was appalled, gong her a look like she did the most unspeakable thing. Something I was trying to avoid(also tried to start because people are so repressed.)
