A couple of days ago one of my fantasies was fulfilled after many years of yearning. I’ve wanted my lovely but vanilla wife to take part in BDSM with me for over 10 years. I have wanted a switch relationship but she’s very much against it. Last week she got ready for work as usual, I had the day off so had the house to myself, the kids were having a couple of days at their grandparents. Before she left she told me that her friend, Lisa, was coming round during the day to borrow a top for a Christmas party. I was told the tops she wanted to choose from were on our bed and to let her just choose one. At about 11 a.m. Lisa arrived. She’s an attractive natural blonde and a good friend, to be honest I’ve never actually fancied her, she’s a mate and a good laugh and that’s that. She went up to our room while I stayed downstairs. After a couple of minutes she came downstairs with the blouse she was taking. She had a devilish smile on her face and told me she’d seen my handcuffs in my sock drawer. I’d left the draw open after getting dressed as being a bloke I’m plain lazy. She asked me if I used them on Dee, my wife. I made a pot of tea and told her I’d bought them in the hope Dee would play and cheekily told her I’d always fancied being stripped, cuffed, spanked, and teased but accepted that Dee wasn’t interested, she explained that Pete, her husband was also very straight and didn’t do anything kinky. Lisa put down her cup and went upstairs, I assumed she wanted to have another look at my wife’s clothes but after about a minute she called to me, not in a sexy way, she just called me to go up. I found her in my bedroom fully clothed but grinning. She closed the bedroom door and told me to turn around and take my t-shirt off which I did. Behind me I heard an un mistakable clink of metal and felt it no my right wrist. Within seconds Lisa had handcuffed my hands behind my back with almost expert speed. She felt around the front of my jeans and could feel how hard I was getting. She undid my jeans and pulled them and my pants straight down exposing my now rock solid cock. She turned me round to face her. She had a real devilish look on her face now as she took her top and bra off. She has the most magnificent tits, DD cup with long hard nipples. “Like my tits?” she asked. “Yes, they’re gorgeous” “Bet you’d love to get hold of them wouldn’t you if you could” “Oh god yes, if you were cuffed I play with those beauties and cover them with my cum” “Dirty boy” And with that she turned me away from her, took my leather belt off my jeans and started using it to spank my butt. It felt amazing, the harder she spanked the better it felt. Then she stopped and I felt something soft in my cuffed left hand. She was placing one of those fantastic big soft round tits right there for me to feel. While I was feeling her she reached round and started to wank me off. She then sat on the bed and told me to face her. She now put my cock between her tits and started to lick the tip and after a few seconds took it fully in her mouth. I would have loved to have had free hands to grasp and cup her tits while she deep throated me but I just watched her going down on me. She felt me starting to cum so took my cock out of her mouth and wanked me all over those gorgeous DDs . I watched her rub my load into them then she went into the bathroom to clean up. She came back in and got dressed, after which she released me and went downstairs and put the kettle on. The whole thing had lasted about 15 minutes but had felt incredible. Over a post playtime cup of tea we agreed to meet again for play and that we would switch with each other. We also agreed that it was purely a bondage friendship and we would never actually have sex. Suits me, I’m looking forward to when we can sneak another half hour, my turn to tie her up next.
