I have always wanted to watch my wife getting fucked by another guy and after some persuading we got into an occasional swing. On one of our first ‘experiments’ we managed to arrange a date with a guy who was in his 40’s and claimed to have a big cock, we thought, what the hell, sent the kids to the grandparents and invited this complete stranger to our house to see what happens. My wife is 35, very curvy with large GG breasts. She wore a skimpy dress and lace undies and we both nervously awaited his arrival. He arrived and gave her a peck on the cheek, I let them sit together and I sat on the other sofa. We chatted for a long time about our experiences and fantasies, maybe an hour or so passed in conversation. We all got on well. He eventually asked if she was turned on about meeting like this and she giggled a little bit and said yes. He placed his hand on her knee and I noticed he worked up her legs very slowly as we chatted some more, eventually exposing her thighs. They got closer and a little more touchy feely until they started kissing. He ran his hand from her cheek and gently squeezed her breasts. They kissed for a while and embraced more passionately, he squeezed her breasts through her dress, and pulled her dress up to reveal her knickers. I saw her squeeze through his jeans obviously finding his bulge as she rubbed it up and down. After a little while he stood up and took his clothes off, his big cock springing out of his boxers, he was easily 9 or 10 inches long and quite thick. I got hard at the sight too!! She licked his cock all over then gently sucked him, he closed his eyes and looked in ecstasy. He eventually stopped and appologised telling her that he had nearly cum. He asked her to stand and pulled her dress off over her head, they kissed standing up whilst she wanked his cock against her stomach. He unfastened her bra and began to suck and lick her nipples, stopping to kiss her every so often. He pulled at her knickers and she slid them down throwing them to me. They moved back to the sofa still kissing, he opened her legs and began to rub her and gently finger her. She was breathing very deeply in inbetween kissing, letting out little moaning sounds. He kissed down her body and moved between her legs, he started to lick her and said she tasted fantastic, after a little while she sighed loudly and came. He kissed back up her body his big cock now pressed against her. She moved up a little and his dick slid into her with a squelch. He began to fuck her gently, kissing her all the time. I had a great view of his big cock sliding into her, her legs wrapped around him. He pulled out and sat down, as he moved I could see her open wet bits and nearly came in my trousers! She climbed onto him and he buried his face in her big tits as they continued to fuck. She picked up the pace a little and let out another long sigh, leaning back as she did so he could enjoy a full look at her huge tits as she came again. He asked if she wanted to try it from behind and she said yes, as they stood up to move round she dropped to her knees and sucked him again, this time letting him go much deeper into her mouth. She climbed onto the settee presented her bum to him, he licked her pink lips making her shudder and giggle before sliding into her. This time he went much harder and faster, her big tits bouncing. After a few minutes he said he was going to cum, she didn’t move but kept backing into his cock, he went stiff then moaned as he emptied inside her, they carried on slowly for a minute or two before he pulled out and sat down. I could see his sperm dribbling out of her, she looked over her shoulder and asked if I wanted to finish too, I jumped up and quickly got my cock out managing maybe three or four thrusts before I sent my own massive load into her. She said that’s better with a chuckle and got a towel to wipe herself up. We sat a little longer before he got dressed, gave her a kiss and said goodnight. We had great sex for days afterwards talking about it and haven’t looked back. As work and kids take over, free time means our ‘fun’ days are very limited but the first few were always the best!
