The greatest sexual experience?

I am sure this is the time when me and my GF had sex in front of a friendly couple who were doing the same thing!!! The whole thing started when they invited us for dinner. After a lot of glasses of wine we started making out with the girlfriends. Kissing, hugging and touching each other. Each couple had a couch and we wanted to have sex there and then....

The wine helped a lot and someone proposed to do something really kinky. To have sex in front of each other. We were so horny that no one said 'no'...

Soon, i was on top of my GF and the other couple was at doggy style! We did it a lot of times that night, but not swinged our partners. It wash great!
