My wife and I have been married 20 years, 3 kids and a relaxed middle aged lifestyle. We havebeen friendly for a good few years with a slightly younger couple. The girl, Jan, wasformerly employed by my wife before going on to found her own, now reasonably successful business. As couples we meet every 3 or 4 weeks for dinner or the like. All very ordinary - until a couple of weeks ago. We'd gone round to Jan and Al's (her other half)for dinner. On arrival Jan said that as the October weather was unusually mild they had decided taht we could have an out of season Bar-b-Q, so we all proceeded to the garden which in their fairly large house is both private and secluded. We settled down and enjoyed a great meal with plenty wine round the purpose built brickwork oven. as the evening wore on the talk turned to how amazingly warm it was for October and Jan said that what with the weather and the heaat from the oven she was cooking - too warm. On saying this she peeled of her cashmere pullover to reveal a silky pink camisole. This was pretty revealing, Jan has biggish tits, 36C or D's i'd say and they pushed through the thin material. I was pretty surprised at this development, but not half as much as when Jill, my wife immediately said "lucky you, I'm hot but I've only got a bra under my jumper". Jan quick as a flash said, with I think a gleam in her eye, "Oh so what, we're all friends". Jill, smirking, said "Yeah, what the hell" and peeled of to reveal her well shaped and perky for her years 34C's in an uplifting leopard print Rigby and Peller bra. Al was beaming - I'm just agog - and now says "nice lingerie girls, what else is there". Jan looked at him and says, "Don't be cheeky you know very well my surprise down there, will I show them?" Al laughed, I could see his cock bulging in his jeans, and said "sure". Jan looked at us questioningly and, again I'm amazed because she had never shown any interest in this sort of thing, Jill almost leers "yeah, lets see". Jan slowly peeled off her tight leather trousers to reveal a pair of black crotchless butterfly panties, her pussie lips already engorged and slightly parted to show the glistening folds of her inner labia. Me too said Jill, standing up to swing off her suede rap around mini skirt and stand before us in her bra an animal print thong and high heels. By now Al had his cock out and was gently wanking the engorged member. Jill then walked over to him, squatted over his cock, and pulling her thong aside began to rub his cock on her pussy. So far I'm the only non-participant - but this is about to end. Jan comes over, peeling the camisole off to reveal her large bouncers, says am I shy, and without further ado undoes the zip of my trousers pulls my grossly swollen cock through the pee flap in my Y's and starts to blow me! I'll finish the evening in a second instalment!
