Motor home.

we were parked up in our motor home for the night .I saw another one parked up so I walked to where i could see in , there appeared to be some activity going on so I stayed still. After about 10 minutes the door opened and a bloke looked at me , I thought he was going to tell me to fuck off, instead he said you wont see much there , come in , so I did. Inside there was a naked woman being fucked by a bloke while the one who called me in watched and wanked, he told me to strip off then fuck her when the other bloke had cum . It didn't take him long before he came in her. when he pulled out i was told to fuck her, they were loving it , so was I while two strangers watched me fucking her . I made it last as long as I could then shot my spunk in her. Pity I never saw them again but still remember it.
