Accidental Swinger (M looking for F)

[Strident]

After a 7 year relationship, my character finds himself newly single at 32 years of age. His world having fallen apart, breaking up with the only woman he's been with sexually in his life, he moves to a new job and a new house at the other end of the country.

A few weeks into his new job, he's starting to feel a little bit more settled, but lonely. Maybe that's why he's started exchanging the occasional smile with a cute girl who works in the same building as him in the work canteen. He joins local social media groups, and sees an advert on one for a private "mixer/socializing" party. He's not really a party guy, but goes along. The party is held in a large very pleasant country house. Everyone seems very nice, chilling out and chatting, eating the buffet food on arrival.

Just then, he notices a familiar face! The girl from work! They've never actually spoken but recognize each other and say hello for the first time. As they start to talk he notices....things...starting to happen in the room around them. People coupling up, groping, kissing. He's stumbled into a swinger's party! And it turns out his newest friend is a regular attender...

Any takers for this one?
