My wife and I were at a wedding with loads of other people and the combination of drink and well turned out individuals got us both really horny... We are trying for a baby too and try to have constant sex to make that happen. Anyway we had to have a quicky so we soon found ourself s in the huge disabled toilet at the hotel reception tearing each others clothes off. We are both in our late 30's, iv an average 6 inches, my wife has smallish tits long nipples tight shaved fanny and good child bearing hips. Anyway I was licking my wife out and she was moaning loudly as she sat on the wash hand basin unit, she hates it if I stop when she is about to cum. So she was reaching this point, when to toilet door opened, shit we had forgotten to lock it in our haste. In shuffles an old guy of about 80 with a walking stick. My misses is too close to orgasm to notice and I can't stop doing the oral so in he comes and starts to get his cock out for a piss, when he sees us in the corner. His old cock, soon turns from flaccid to erect in a second and he lets his old suit trousers fall down. He starts wanking and I give him a wink, my wife and I like to be watched. My wife reaches her orgasm and openens her eyes to see the old bloke shuffling closer. She gets a start but I explain he is only watching, and she agrees to him being there. The old guy says he has not had pussy in years and he would, love to slip in for a second. I look at my wife and she is reluctant. Your a bit old ? Yes he agrees but you would make my day for 30 seconds of being inside you! It's been my fantasy for ages to, see this sort of thing so I'm up for it. My wife says ok but don't cum in me we are trying for a baby, I don't think my husband would like that. I say, yeah best not mate. So he shuffles forwards and puts his clock,on her fanny lips and slowly pushes in while my wife and I watch the first man to enter her pusy other than me since we were married. 30 seconds later he is sucking my wife's erect nipples and I can see she is loving this dirty sex as she is dripping juice out her fanny onto the floor. I'm cumming old man gasps, as his heavy old balls bang against my wide arse, oh shit my wife shouts ! She wants to stop him but also loves being filled with cum! Please can I cum in you he gasps? My wife and I exchange glances, we are trying for a baby, so it's dodgy, but she is enjoying this too much, Ok my wife says, Grunt goes the old man, and a torrent of sperm rushes up his cock into her, just as he gives a deep thrust to get his cock up to her cervix. My wife pulls his arse in deeper to her, and I can see ball sack pulsing as he empties his old seeds into her fertile young womb. They stay joined for a minute, until his cock goes soft and plops out, followed by a leakage of combined juices that's running down her arse and legs. We thank the old boy, and he goes, the I turn to my wife for my turn, but she has pulled her pants up and her dress down. Hey my go I ask? No I'm too sore, maybe later, his cock tip was in my cervix he came, it's too sensitive just now. Well all I could do for the next few days was lick my wife's pussy as old mans sperm leaked out because it was too sensitive. It was a week before I shagged her next... Low and behold a subsequent pregnany test is positive and our dates tie up with that wedding! Old bastard got her pregnant! She is now carrying an 80 year old mans baby. But at least I can suck her milky tits as time goes on... Wait till next wedding instalment....
