I dont know why, but something about how filthy this is is really hot!
This brings back memories of going on vacation with a gf and another young couple. When we got to the camp site the caravan had one big double bed in one section and bunk beds in another. The other girl who was drop dead gorgeous said she'd come on holiday to shag and not sleep in seperate beds. My gf suggested alternate nights for the bed, not much enthusiasm for that so I said 'It's a big bed why dont we all get in together' and thats what we did. The first night we stood looking at the bed so I stripped off revealing my hugh hard-on for all to see, this gorgeous girl couldn't take her eye's off it and the others undressed and as two couples we fucked and fell asleep. Some hours later I awoke with my back to the other girl and as I rolled over to face her she awoke, looked at me and said 'I want you to fuck me' It wasn't possible without wakening the others so I fingered her pussy and she played with my cock as we held each other and kissed. The following day we managed to be alone and we fucked for real. Once back home we got together as lovers and enjoyed many happy months together.
