This all happened in the UK January lockdown of 2021.
I was isolating with my gf (Beth) at her flat along with her flatmates and another one of her flatmates partners (Megan).
Me and Beth are sexually open couple meaning we can sleep with other people as long as we ask the other first. This has led to us having a very healthy sex life and when we do have sex we care very little about making to much noise so the rest of the flat normally knew what we were up to lol.
Megan was the gf of one of Beth’s flatmates and she was an absolute stunner (way out of his league). She was quite short with big boobs, a slim thicc body and a fat ass that noticeably stuck out. Furthermore because we were all stuck inside all day she’d taken to wearing tank tops and short shorts most days which really made her ass and tits pop.
Megan has previously let slip that her bf wasn’t sexually satisfying her and that after this lockdown she was thinking of dumping him for this reason. She’d drunkenly said she was jealous of our sex life and said how she can hear us in the evening.
