I have been married to my wife Sue for 40years. We married when she was 18 and I was 24. She was virgin and I have been her only sexual partner. We decided to have a party to celebrate. Sue has a nice figure still at 58. She is a 38c and has long shapely legs. She is a natural blonde and keeps her pubic hair to a small triangle above her clit and is smooth from her clit to her arse. Sue likes to wear stockings rather than tights and a nice thong. We have a full sex life, vaginal, anal and oral sex. She does like to swallow my cum. I asked Sue what she would like as a present to celebrate our 40th. She said just a party. I said to her how about another man to have sex with. Experience another penis. She said I’m happy with you. Then she said what would you like. I told I would like to watch another man fuck her. Well, that’s not going to happen she told me. I said alright then. I will stay downstairs while you fuck upstairs. She said are you being serious about me going with another man. I said I was not a virgin when we met, but you were. Don’t you want to see and experience another man. This conversation went on for a few of weeks. Then a couple of weeks before the party Sue said to me if your serious about me having sex with another man lets talk about it and see if we can arrange it. I was taken aback. So, we discussed it.

We did some research and looked at various swinger sites and to go to a club about fifty miles away. Hoping nobody we knew went there.  We arrived and were shown around by the owners. In the changing room, Sue quickly undressed and put on a bra and her stocking and suspenders with a string thong. I just had a pair of boxer shorts on. We went to the bar area and other couple made us fill welcome. This place had a sauna, steam room, a jacuzzi, play rooms and a cinema showing porn.

We did mingle and ended up in the cinema. There 3 or 4 couples already having sex. We did watch and one couple beckoned us over. They knew we were newbies and told us to watch them. He then started to fuck the women and play with her tits. As he fucked her, she reached out and took my hand and placed it on her right tit and told me to play with her nipple. This got me aroused and my swollen prick popped out of my boxer fly opening. I told Sue to take her bra off. She took it off and the bloke lent over and kissed each one in turn. I could see she was aroused as her nipples swelled to twice the size and were hard and erect. We decided to leave our new found friends and see what else we could experience. I asked Sue how she was and she told me she at first, she thought she would run out, but now she was feeling extremely sexy and wanted to see more. We wandered over the playroom area and in the first room we saw a couple on a mattress fucking. Both were naked. We went in and got on the mattress beside them. I had taken my boxers off and Sue her thong off. The couple next to us changed position. She was now straddling him as they fucked. Sue reached over to the side and took a condom from a box provided for everyone. She rolled it on my prick and she straddled me and we fucked. The women next to us, moved up and straddled the bloke putting her pussy in his face. Sue then lent over and took hold of the bloke’s erect prick and slowly wanked him. She then got off me and got between his legs and started to kiss his balls and then his shaft before taking his penis into her mouth giving him a blowjob. I turned on my side and watched my sexy wife sucking another man’s prick.

Then two men walked in and got on the mattress with the couple and Sue. The first asked if they could join in. The female said yes. Sue looked up and said join us. I watched as the first bloke started to play with the women’s tits. The second got behind Sue. His prick was already erect. He started to play with her arse cheeks, then fingered her pussy. He looked me and I nodded and said go ahead. I got him a condom. He put it on and shuffled behind her, grabbed her hips and eased his prick into her pussy and started fucking her. She lifted her head up and put her hands on the mattress to steady herself as she was fucked. She looked at me, blew me a kiss and started to moan as he pumped in and out of her pussy. I leant over and played with one of her tits as they swayed about as she was fucked. Her nipples were rock hard. The first bloke then knelt beside Sue’s head. She turned her head and took his hard prick into her mouth. He proceeded to fuck her mouth. He lasted a couple of minutes while playing with her other tit. He jerked and came in her mouth. She swallowed all his cum with a bit dribbling out the side of her mouth. The bloke fucking her came. They thanked us and left. The woman got off her bloke and pushed me back and straddled my hard prick. She fucked me while Sue sucked her man until he came and then I came. We thanked them and left the room. Sue and I went to the locker and put what clothing we had on in the locker and then returned to the Cinema naked. Sue said she was glad that I let her be fucked by another man and wanted to see if she could take more if I didn’t mind. I told it excited me seeing being fucked by someone else.

While sitting watching the porn a bloke sat next to Sue, on a seat in front of her and one behind. I turned and started to play with her tits. She got aroused again. Without any prompting she took hold of the bloke’s semi hard prick next to her and wanked him. The bloke behind her stood up and leant over and joined me in playing with her tits. The bloke in front stood up and Sue then leant forward and gave him a blowjob until he came in her mouth. She bent over and sucked the bloke next to her. He came in her mouth. She told the bloke behind to sit down. She climbed over the seat and lowered her anus onto his stiff prick and she fucked him until he came up her arse. Then her and I went to a shower and I cleaned her arse of cum. She wanked me off in the shower while a couple of blokes watched us.

When we got home Sue said she really enjoyed being fucked and liked blokes watching her fucking and sucking other blokes. She has asked if we can go again and even try another club. I said perhaps next time she could try a gangbang. She just gave me a smile and squeezed my balls. At the party she did tell her two best friends what she did and that they should try it with their husbands.  They both said to Sue they should make it a girls night out, even staying overnight at a nearby hotel. Lets see if that comes off.
