Let me start by explaining that I didn't realize what cuckold entailed till Gill and I started reading the stories on here. We've been together now for abot 4 years both in our mid thirties and comfortably off with nice house cars etc but we now know whats been lacking in our sex life and that is a new thrill which entails Gill going out dressed to the nine's and me waiting at home anxiously for her return. Up until very recently she has been going to a trendy bar in town on a Friday with her mate from work who's single but not really what you'd call a looker, a bit plain but with a nice smile. Gill tells me that she's no stranger to sex and from the sounds of it has had alot of expereince and not only with one bloke at a time! Each Friday Gill has been a bit more daring, gaining confidence I suppose, with what she wears and this week she came into the lounge as normal to get my "approval" and to tell me to be ready for her when she came home. But this time she had on a short dress that I'd not seen before which showed alot of her 32c tits and even more of her bare thighs. I could'nt resist running my hand up her leg as I kissed her goodbye and I found she had the tiniest of thongs on!!! She just winked at me and giggled like a schoolgirl and in a flash she was out the door and down the drive in her car. I woke up at a noise outside and looking at the clock saw it was almost 4.00am. On going to the window to investigate I could see Gill sitting in her car with the interior light on and the passenger door open. I was about to open the window and call to her when out of the corner of my eye I saw a guy in a dark suit come out from behind our hedge zipping himself up and got back [as I later found out] into Gills car. The light automatically went off and I just stood there behind the curtain straining to see but it was pitch black. I could feel my cock starting to grow in my boxers and was about to get it out for a rub when both car doors opened and I saw Gill and this stranger approaching the house. By now I was well intigued half jealous half anxious but thought I'd take full asdvantage of this situation and moved to the bedroom door to listen as they came into the hall. Gill was talking reasonably loudly and as she didn't drink it wasn't alcohol fuelled.... I could hear her every word as she ushered her "friend" into the lounge telling him that she would make him a coffee after she'd been to the loo. She came upstairs and was glad to see that I was awake, although I had got back into bed when I heard her climbing the stairs. what do you think? she asked as she put her head round the door. Still want to go through with this fantasy about cuckolding or shall I just give him a coffee and send him on his way. My heart was racing and I started to stutter that if she fancied him and wanted to then lets grasp the moment and do it. She came over to me put her hand under the covers and straight into my boxers. Feeling me as hard as a rock she kissed me on the lips, smiled and walked out. I could hear the small talk between them and I could imagine by now she'd have her shoes off and be lying on the sofa nuzzling up to him. It suddenly went quiet so I decided to sneak downstairs and get a bit closer. I grabbed a robe from the back of the door on the way and gingerly went down the stairs one by one. I still could'nt hear anything even when I got to the lounge door so I peered through the crack to be met with one of the horniest sites I have ever witnessed!! Gill was on her back on the couch with her legs wide apart minus her thong and this blokes head was stuck right in between them. She was biting the back of her hand to try and stifle the sounds of her cumming but I knew only too well she wanted to scream the house down. She was urging him on now saying go on lick me, stick that lovely tongue up me, suck me, bite my thighs, mark me, I want you to bite me........ At this, her man stopped, replaced his head betwwen her legs with his hand and slid along the couch till he was level with her. He spoke softly into her ear but loud enough for me to hear him ask, Are you sure you want to be marked? Don't forget you're married, how will you explain that away? Still with his right hand playing with her clit and I suspected ass hole, cos she loves that, he asked her again and thats when the sudden realisation of what was happenning hit me. "Just do it" she screamed out. " I want to be covered in bite marks so I can show him what I 've been doing and he can wank his tiny little cock while he looks at them" "I know your cocks much bigger than his cos I had a good feel of it in the car and I can't wait to get my mouth around it and feel it up me" That was it she came with the most shattering climax on his hand obviosly turned on so much by her vocal outburst and of course my already throbbing cock was about fit to burst also but I stayed motionless while he gradually brought her down from her high..... I must say he was very attentive no wonder she was enjoying herself. He carresed her brow as she calmed and whispered niceties into her ear which made her smile and then gently took each of her tits into his mouth and sucked. I t was only when she let out a whimper that I noticed a bite mark on her left one as he moved on to the right. The whimpereing started again so I asumed that he was giving it the same treatment and as the whimpereing got stronger I saw Gill struggling to release his cock from his trousers. With a little help it was free and I must admit it was big.. She wasted no time in positioning herself so that she could take as much as she could into her mouth stopping now and then to lick the lenghth up and down and to suck his balls independantly. Each time it was accompanied by glowing compliments on his fine manhood. This went on for some time and my own cock was having a bit of a shuffle by me but I wanted to hold back until he actually took her but I knew if he didn't do it soon it 'd be too late and I'd shoot!!! That was when she suddenly got up, laid flat on her back and ordered him to "fuck me big boy and make me sream" As he positioned himself to do just that he asked about me and what if I woke up. She just laughed and told him I was probably behind the door watching them anyway cos thats how I got my kicks. I couldn't beleive my ears but fortunately he either didn't beleive her or was too busy making love bites on her inner thighs to hear...... He started to fuck her with all his strength and she loved it. Especially when he got her on all fours stuck his cock up her fanny and two fingewrs up her ass. She even brought her own hand down between her legs and rubbed her clit but it was all too much for me, I spunked into my left hand and then went back upstairs to wait.... To be continued.
