I’m not proud of what I am about to tell you, but I have become hooked on this type of sex. I’m 58 and married to Clair 57. Clair had never been keen to experiment and I still don’t know what happened to cause such a big change but change she did. My wife went from a woman who enjoyed simple sex with her husband who becoming almost obsessed with watching me having sex with a 19 year old daughter of our friends. It started when we went to our chalet in Cornwall last year. With us was our friends and their daughter who I’ll call Susan. Susan was 19, a pretty young lady, slim with quite a large chest and full of fun. We decided to stay for an extra week so it was decided that Susan would stay with us whilst her parents went home. There was nothing to suggest that what happened next was on the cards. Clair and I had talked about Susan and how grown up she was and what a job our friends had keeping the ‘wrong types of boys’ away, meaning lads that just wanted to go out get drunk and have sex. But it was Clair who was the first to comment, something like ‘but you can’t blame them’ saying that she was quote hot. I looked at my wife who just shrugged her shoulders saying, ‘don’t tell me you wouldn’t’ then walking away said ‘I would’. I tried to get clarification, but she clammed up and nothing else was said. The next morning, we had planned to go out for the day, Clair had just come out of the shower and Susan had just gone in. I tried my best to get out of her about what she had said but was getting no were. After about 20 min the shower was free and I went in. I will admit that I masturbated thinking of Susan but at no point did I intend to try anything on with her. I got out the shower and with just a towel wrapped round me went into the bedroom where my wife and Susan where sitting up on the bed. Clair with a dressing gown on and Susan with one of my long shirts on and clearly nothing else, and the buttons were undone so it was just laying over her breasts. Her legs were under the quilt so I immediately wondered ‘was she naked other than the shirt’. Clair said ‘we’ve been chatting’. I asked ‘about what’ still standing there in just a towel glad that I had just had a wank and wasn’t getting too hard. ‘about how men love Susan’s figure’ followed by ‘what you’ve got under there’ pointing to my towel. I told my wife to behave and that we needed to get ready. Susan and my wife giggled with my wife saying ‘ I told you he’d be shocked’. My wife said ‘don’t tell me this isn’t getting you hard’. I was so shocked that I told her to behave and apologised to Susan who told me not to be silly and that she didn’t know that we were ‘like that’. Clair went onto her side and faced Susan and rested on her elbow. She told me to come closer, I decided to join in the farse for now. Clair pulled open the shirt Susan was wearing to show off Susan’s near perfect breasts. Big and full, her nipples big and hard. Susan giggled and shook her shoulders to make them move. ‘are these not the best breasts you have ever seen’ , ‘ apart from mine of course’ Clair said opening her dressing gown to show off her smaller softer breasts. I felt myself getting stiff again and told them to behave. For the first time in my life I was almost speechless and didn’t; know what to do. I was close enough for my wife to reach out for my towel. I moved back to stop her pulling it off but Susan grabbed it and paused. Clair said that she had told Susan that I had a big cock to match her big tits. She told Susan to ‘pull it off’ and with one tug I was standing there naked, my cock semi hard. Susan shrieked and covered her eyes, Clair lunged forward over Susan and tried to grab my shaft. I moved back out of her reach. She shouted at me to come closer, Susan put her hand behind my leg and pulled me closer. The sight of my wife, now topless leaning over a topless Susan, her breasts pressing against Susan’s encouraged my cock to get harder. Clair noticed the sudden change and laughing asked me if I liked that and started to move in a way that made it look like she was rubbing herself against Susan which made Susan laugh even more. By now I was less than a few inches from Susan’s face. My wife quietly reminded Susan that she had told her that I was a ‘big boy’ adding ‘ I told you he was a mouth full’ . Now I was semi erect and wondering how far this joke was going to go. My wife leant over again and grabbed my hand and pulled me so my legs were was pressing against the bed. ‘She whispered to Susan ‘go on’ and with that this sexy 19 year old with smooth skin and large breast and long legs with wife hips to compliment them looked at my wife before moving onto her side, taking my semi hard semi soft cock on her hand and sliding her lips over it. I stood there with my wife still holding my hand tight. She watched in amazement as our good friends 19 year old daughter slowly sucked me off. I remember being grateful that I had always shaved myself down there as I still and felt her tongue flicking my shaft and felt her sucking my cock. I looked at my wife who looked up at me then back at what Susan was doing. This lasted a few minutes, Clair telling Susan to ‘look at his big balls’. Without breaking her stride Susan cupped my balls and gave them a gentle squeeze. Now I was hard as fuck. My wife looked down at the quilt and pushed it off with her legs. Susan was naked apart from the open shirt. By now Clair was breathless along with Susan. She pulled at Susan’s arm for her to move to the centre of the bed. She pulled the dressing own off and returned to her side resisting against Susan’s amazing body. She started motioning to me to get onto the bed, telling Susan, ‘come on, telling her that she will love me inside her. I looked at my wife. Was she fucking serious? Having the girl suck me off was one thing but getting me to fuck her was another. I tried to get her attention without making a scene and embarrassing Susan. My wife repeated herself over and over ‘come on, come on’ as Susan slid to the centre of the bed. Then my wife looked up at me telling me to come on and ‘put your cock on her’ with ‘she wants you to put your cock in her’ turning to Susan for confirmation. Susan was still sitting up, she slid down onto her back, opened her legs and touched herself ‘please’ she said ‘fuck me’. What was a man supposed to do. I went down on her smooth pussy, her juices tasted so sweet. I lapped her up, Susan starting to moan, my wife rubbing herself watching and moaning as though it was her I was eating. I was enjoying myself and Susan seemed to like what I was doing, but my wife insisted that we fuck. ‘ put your cock inside her’ she told me. I climbed up Susan’s amazing body, taking her nipples in my mouth and suckling on her until my wife repeated her please for me to fuck her. I was surprised at how difficult it was to push my cock into her. She was tight and my cock is quite thick but in the end she was so wet it slid in. Susan let out a half scream half groan as I pushed it deeper into her tight pussy with an ‘oh fuck’ that was dragged out for a good 30 seconds. Susan thrust her hips into me repeating ‘ oh fuck, oh fuck’ my wife asked her if she was alright to which Susan answered with a ‘fuck yes’. For the next fuck knows how long I slowly fucked our friends 19-year-old daughter. My wife pressing against us masturbating and groaning as long and hard as Susan was. In the end both Susan and my wife started to plead with me to fuck harder so I did. I started to pound Susan hard, she gripped the bed still thrusting her hips into me but it was my wife’s actions that sent me over the edge. Susan’s tits were bouncing and swaying, my wife was crying out, her fingers fucking her own pussy. Clair turned her self onto Susan and started to fuck the breast closest to her. She sucked hard lapping her nipple with her tongue before returning to sucking it. I felt my wifes fingers round my shaft as it slid in and out of Susan’s wet pussy. That was too much for me, I warned Susan that I was going to cum and withdrew my cock from her pussy just in time for my sum to spray her tummy, her tits and har face. Susan cried out that she had wanted me to cum inside her. I was still hard to I entered her again and watched my wife suck Susan’s face and proceed to suck the cum from her breast’s, chin and stomach. That was enough for me to cum for the third time that morning. Once in the shower, once aver this hot young woman and again inside her. Susan let out a scream, arched her back and climaxed hard. My wife returned to her side of the bed and masturbated, rubbing her clit hard gripping her own breast with her free had before she also climaxed. Susan, Clair and I fucked every morning and every night for the remaining 6 days. We fucked in bed, on the sofa, on a chair and against a wall with Susan sandwiched between me and my wife, sometime it was Clair on the middle of me and Susan, hands and tongues exploring every single part of each other’s bodies. When we got home the fucking continued two and sometimes three times a week until we had to stop due to the virus. I know they are eager to re-start our ‘personal time’. Clair and I talked about how this all started, my wife just saying ‘we decided’ and leaving it at that. My wife wants to ‘expand our horizons’ with a ‘big bull’ in our bed. So I guess we will be shopping online for her ‘big bull’ when we are free and safe to do so.
