I had been nudist for some years but my wife did not want to so, we were restricted to Clothing Optional caravan parks etc on our caravan trips and we made a lot of friends. I also did my share of swinging prior to meeting my wife, which she didn’t know about, anyway, about 3 months ago my wife went for a walk around the park and hadn’t returned for some time, so I went looking for her and as I went past a van a heard her rather animated voice so I went in and there she was on the bed having a threesome. It took me by surprise seeing her with another man fucking her while his wife was sucking on her 36dd size tits and she was fingering my wife while his dick was thrusting away. My 55 mm wide dick immediately got rock hard and I climbed onto the bed. His wife immediately spread her legs and said come and fuck me while my husband is fucking your wife. I immediately shoved my hard dick in her honeypot and she was sopping wet and she let out a huge moan as my dick entered her. It appears my dick was much bigger than what she was used to. It didn’t take me long to come inside her with a boatload of cum and she just lay there with her body quivering. By that time the husband had finished inside my wife so we swapped places. This time I pushed my 55mm wide dick in my wife’s ass for the very 1st time and I know she loved it as she joined in the rhythm and squealing like I have never heard before. No surprise to say that was the start of many more swinging sessions. Let me know if you want more.
