Short story/novella (24,718 words).
Sophie and Josh are the couple who still whisper and kiss and make out in public long after everyone else has stopped. After six years together, they still have sex a lot, two or three times a day, pretty much every day, and often in stupid places too. They are always on the verge of being caught.
One day they are. While Josh is groping Sophie outside a stranger’s house, the owners of the house come home. Sophie is embarrassed, and tries to slip away, but to her surprise, the couple who’ve just caught them seem to want to watch.
She is even more surprised to realize she doesn’t care, and neither does Josh. So they do. They let the other couple watch, while Sophie gets off on Josh’s fingers. And then they are asked inside, and the talking and flirting seems to be leading to partner-swapping, in the gentlest, politest way imaginable.
Sophie isn’t shocked. She actually thinks it might be fun, and Josh seems interested too. Sophie is sure their relationship is strong enough to survive any problems this might cause, so she lets herself be talked into sharing sex with another couple. And it turns out to be one of the best things she has ever done.
