A couple years ago we stayed with my in-laws, something we haven’t done in a long long time. They have limited bedrooms so we got to sleep on an air mattress in the den; there was a door but it didn’t latch let alone lock. For the first few nights we behaved ourselves but eventually we both got so horny that we couldn’t keep our hands off each other. Everyone went to bed early on Christmas eve and that was our opportunity to fool around.

My wife was wearing a long soft dress for pajamas so she hiked it up and rode me, right under her parents’ bedroom. The air mattress we were on kept squeaking which was both terrifying and arousing. I had to keep one hand over her mouth to muffle her moans because she’s normally so loud and used to having the whole house to ourselves. It didn’t take long for her to cum, then I filled her pussy.

We tried to get up early and shower but ran into my FIL who informed us the hot water tank had died and showers were a no-go. So we sat watching sports and sipping coffee with him, with his daughter’s cum still all over my cock and her pussy leaking mine.
