My wife and I used to frequent a naturist health spa in London. My wife always attracted a lot of attention, size 10 with 36C boobs. I liked sauna and she liked steam, so after 5 minutes in the steam room with her I told her I was going into the sauna. I walked out of the steam room and nearly bumped into someone trying to get in. He asked if there was anybody in there. I told him that there was only a hot French girl (don't know why I said French) "Oh good" he said and went in. I was curious now and decided that I needed more steam and followed the guy in. My wife was lying on the bench naked, with her eyes closed. He sat at my wife's feet so I decided to go into the furthest corner where my wife couldn't see me. We were there quietly for a minute or so, when he suddenly asks my wife if he could massage her feet. I expected her to say no, as she is quite shy, but she opened her eyes, smiled at him and said "that would be lovely". The steam suddenly started pouring through the vents and visibility was reducing so I shuffled along a bit and watched the guy gently massage her feet. He took her left foot and placed it on his thigh and gently kneaded the sole. He did the same to the other foot taking his time gently rotating the foot and ankle. Then he started massaging my wife's calf. She told him that that was not her foot and he moved back to her feet, but not before gently opening her legs a little. I could see she was now very relaxed and as his hands strayed again along her calf she said nothing. He got bolder now and rubbed around her knee whilst gently prising her legs slightly more apart. I wondered if her pussy was moist and glistening as it usually turns her on to have her feet played with. Her right foot was now high on his thigh and her left foot was on his knees and his hand was wandering up the inside of her leg He was very patient and made slow movements up and down her leg then he placed a hand on her stomach whilst continuing to massage her foot with his other hand. She responded by parting her legs slightly. He was interrupted by someone coming into the room and without taking his hand from her stomach, he looked up and put his thumb up before returning the hand to her feet. The new guy sat by my wife's head leaning forward and deeply inhaling the steam and the massage guy resumed his stroking, starting again at her feet and moving his hands slowly up the inside of her calf. She slapped his hand down saying "that's not my feet" and then closed her eyes again. Undeterred by her objection, he started again up her calf to her knees and then back down in small circular motions kneading her feet and rotating the ankle. He got bolder again, stroking up the inside of her thigh, tracing his finger along her groin and brushing lightly over her pussy. I had my hands in my lap covering an ever growing erection and the guy sitting at the other end was definitely taking an interest. His hand was gently playing up and down on the soft part of her inner thigh. Then he brushed lightly along her groin whilst continuing to hold onto one foot. My wife's eyes were closed and her nipples were beginning to harden. Then, as he ran his hand over her pussy, she sighed deeply and raised her hips, offering herself to him. He inserted two fingers into her pussy and used his thumb to roll over her clit, eliciting small sounds of pleasure from my wife. The guy sitting at the top decided to get involved and tentatively placed a hand on her breast. She grabbed his hand and pulled it firmly onto her boob then placed her hands over her head, seeking out his erection. The massage guy had upped the tempo and was getting slurping sounds from my wife's now very wet pussy. He was in and out like a piston rubbing his thumb over her clit on each up and down stroke. Meanwhile, my wife had found the other guy's dick and was pumping away in time with the massage guy. She came, explosively and noisily and slumped back onto the tiled seat still with a dick in her hand. After a few moments she turned over and started to get onto all fours. I tried to slink back into the corner but her eyes met mine and she held my gaze while she lowered her mouth onto a dick then kept eye contact as her head bobbed up and down. Massage guy was now in her pussy pumping gently and my view was once again becoming obscured as the steam vents gushed into life. at the same time, the door opened and the steam gave way to 2 girls and a guy entering. My wife disengaged and sat up and there followed a period of embarrassed silence before one of the women asked if they were interrupting anything. My wife stood up and said no, she was just leaving, so I followed her out with my hands covering an unsatisfied erection and as I did so I shrugged to the two guys, feeling their frustration...........and so on to the jacuzzi.
