It has been a long time since I've written on SH, previous stories can be read by searching John_B. Basically my wife and I enjoy a third person in our relationship. Initially I thought I was a Cuckhold husband however the more we have read and learned Fiona is actually a Hotwife as there is no humiliation for me that would exist in being a cuckhold. We are both professional people and very mature. We started our fun with Fiona meeting another guy in a nightclub 20 years ago when we were both 30 and now this year we are both going to be 50. It started with one night meets for Fiona and now Fiona has been seeing the same guy for 2 years. Duncan is 34 and Fiona actually went to school with his brother so we knew this one carried a risk however I think that is part of the excitement this time. Duncan does not know I am aware of Fiona's fun with him, he thinks they are having an affair without my knowledge therefore cannot parade Fiona to his family. If they go out for a night they go to another town and enjoy the trappings of weekends away as couples do. She has been to a few works nights with him with the other guys from the station. Initially our fun when we were 30 was for Fiona to meet some guy in a club with me watching from safe distance and then for her to go off with him and kept it that way for a while but she started seeing guys more than once and then obviously met Duncan so things have changed from just being a few hours away having sex to actual full weekends away. This was exciting but changed the dynamics slightly and on occasions if we had sex the morning Fiona was going away or if I decided to masterbate I would lose some interest and try to put the meeting off. This caused a little discussion between Fiona and I as she pointed out the hotwife part of our relationship was instigated by me and she went along with it happily however made the point when I get the urge its her that has to do the teasing and flirting in nightclubs to pick up a guy, and now at that time when we were mid-late forties it wasn't so easy even though she is a very sexy lady. We researched the internet and all the hotwife/cuckhold sites and actually chatted with other couples on SH and discovered it is a common theme therefore asked couples how they dealt with it and what came from that was that the guy gets a chastitiy cage where his cock is locked away and the key is held by the partner. After reading all the info we agreed that would be the best way forward if I wanted the sexy fun to continue. We bought one and started locking me in 72hrs before she was going out with Duncan, so if she was going out on a Friday night the cage would go on my cock on the Tuesday night obviously after raunchy sex between Fiona and I with her telling me all things about Duncan. It is very long if they are going away the weekend but does add to the fun and removed the risk of me derailing our sexy fun. As we are all professional people we have had to observe lockdown however I listen to them having sexy chats on the phone and Fiona relays all the text messages from Duncan that are very sexy. Fiona often teases she wished she had been in lockdown with Duncan and i'd have been in the chastity cage the whole time...that would have been torture lol! The last they met was a night out at Duncan's where they drank two bottles of wine and Fiona was wearing a lovely short black skirt and black satin blouse, the skirt buttoned up the front and we had enjoyed shopping for it the weekend before. We love shopping for clothes for Fiona together and then I help Fiona dress before she goes out. That night I helped her on with her blouse and buttoned it up for her, at Duncan's request that Fiona does not wear a bra when she arrives. Fiona has very large nipples and even in her bra and she is aroused you can see her nipples standing erect, Duncan loves this look and obviously in a satin blouse they would be very erect. We then slipped on a new pair of black crotch less panties we had also bought on our shopping trip. I have always been allowed a short lick of her pussy or a play with her nipples as I am dressing her and that night Fiona allowed me to play with her nipples and breasts, its all part of the fun as she sets her phone alarm for 1 minute and that's all I'm allowed and not allowed to use my hands...all part of the fun. After sucking on her nippples for 1 minute I placed her satin blouse on her and buttoned it up fully in the knowledge Duncan would be unbuttoning in a few hours. I then did the same with the new skirt buttoned it on Fiona knowing Duncan would unbutton later that night and mentioned this to Fiona. Taxi was called for 6 and Fiona was ready putting her jacket on over her satin blouse with very erect nipples. I spent the night having a drink so I could drop off to sleep early . I received the odd text from Fiona but she can't say or text too often when with Duncan so he does not become suspicious. She said they had some food and drank two bottles of wine. Thet kissed a lot when she arrived but it was clear Duncan wanted to view Fiona for a while before they had sexy fun so she said they sat chatting and when they were on their last glass of wine Duncan moved closer and started to kiss Fiona sliding his tongue in to her mouth and she reciprocated sucking his tongue. She said her nipples had been erect most of the night but now she could feel them very hard, Duncan noticed this and ran his hands over her satin blouse teasing Fiona's nipplpes even more. Fiona said she sarted to unbutton Duncan's shirt and removed it then played with his nipples , kissing them and licking them gently. She then unbuttoned his trousers and removed them then kissed down his chest before slowly taking his cock in to her mouth, licking it and sucking it passionately. She said Duncan was getting very close to cumming and pulled Fiona up to kiss again and restart the playing with Fiona's nipples and started to unbutton the blouse and dropped it down just over Fiona's shoulders holding it there which meant her arms were restrained and started licking Fiona's nipples driving her wild. Duncan then moved one hand down and instead of opening the buttons slid his hand up her thighs touching her holdups and eventually entering her crotch less panties to what Fiona described as a very wet pussy. After teasing her clit Duncan started to unbutton Fiona's skirt and let it drop on to the sofa, Duncan sat back on the sofa and Fiona could see he wanted Fiona to straddle him, as Fiona's blouse hadn't been taken off she said she pulled it back over her shoulders as she straddled Duncan who ran his hands over the blouse as he thrust his cock in to Fiona's pussy then placed his hands under the blouse on her breasts teasing her nipples more. As Duncan fucked Fiona leaned forward and kissed Duncan and just at that point Duncan said he was coming and Fiona felt she was close and both orgasmed together with Duncan shooting his cum fully up Fiona's very wet pussy. Fiona returned early in the morning as Duncan was starting work at 6 and I was so pleased to see her although she wanted the cage to stage on until she had a sleep which was fine as we spent the rest of the day in bed with me getting lots of attention. Looking forward to when lockdown is over so our fun can restart. Stay safe
