I knew mum had caught me masturbating but I thought she was as embarassed as me and had pretended it hadn't happened. She never said anything and I thought that was it. Then the next week came the shock of my life.

Mum always went out on a Tuesday evening. The only thing was that this Tuesday, at the lunch table mum said she wanted me to come out with her. I asked her where but she just said a surprise ... my treat. I asked how I should dress and she said just casually.

When the time came I put on jeans and a tee shirt and when mum asked if I was ready I looked at her dress and wondered if I was under-dressed. "You will be fine" she reassured me.

She asked if I could drive because of her heels so I did and she directed me. After a while on the main road she started to direct me into what seemed like the middle of nowhere. Eventualy we came to a big country house and drove up the drive. The car park was fairly full. We got out of the car and walked to the front door. Mum pushed it open and led me inside. There was a recption area with a young woman at it. Mum told me to sit on the other side of the hallway as she went and spoke to the receptionist.

I watched closely as they chatted, motioned at me, filled in some forms and then mum brought them over to me. "Just sign here." She said and gave them to me. I went to read the first one but mum said, "We haven't got time for that; just sign them." I signed all three and gave them to mum who returned them to the desk.

"Come with me." Mum looked at me and started walking down the corridor. I followed and as we approached the door at the far end I could hear music and voices. Mum led me inside with a smile and as I entered it appeared initially like a large bar. She led me to a table in one corner and as I made my way I noticed the waitresses were topless and in stockings, boots and nickers. I smiled and then remembered who I was with and looked back at mum perplexed. "Sit down." she directed as we reached the table in the corner. My cock was hard from the sight of the waitresses and as I turned to mum to ask what this place was she placed her hand on my crotch.

My immediate instinct was to recoil but it felt nice and the scent of the place had me really horny. Mum smiled, gripping my cock through the jeans. "It's like this ..." mum began "those forms you just signed consent to everything that happens in here.

"The first form simply states that you are free of any diseases and that you submit to any tests deemed necessary by the management. Since you have not been sleeping with anyone then that one is fine but someone will still want to come and take a test in a little while to be certain. Then the second form was temporary membership because this is a private members club." Mum was squeezing my cock as she talked and it felt great. It was throbbing and aching. She continued "The last form I should have checked with you but I didn't want to spoil the surprise."

I looked at Mum perplexed. "It was the disclaimer. By signing that form you consent to everything that happens in here. This room is tame but when you go upstairs or downstairs then that form comes into play. You see in here there is no such thing as rape. you consent to whatever anyone else wants to do to you short of permanent physical mutiliation or death. If you want to avoid pain, do not go downstairs. This floor is limited to heterosexual one-on-one relationships."

At that moment a waitress came over with a glass and a syringe. "Spit!" she ordered thrusting the glass in front of me and then, without warning, she jabbed the needle in my arm and withdrew a sample of blood. I spat in the glass, she handed me some cotton wool and I pressed it against the mark where she had taken the blood.

We shared a drink whilst we waited for the all-clear and I noticed a couple on the other side of the bar keep looking at us.

Eventually the waitress returned with a chain and handed it to me.

Mum put it rond my neck and I looked and saw most other people in the bar were wearing one. Mum had already put one on when she arrived. Immediately the couple from across the bar came over. The lady looked younger than my mum and the man a little older, but she was the one that spoke. She spoke to mum by name and said "May we take you and your boyfriend upstairs?" Mum smiled at me - she still was massaging my cock through my jeans and the woman watched her do so.

"Of course." Mum replied and got up, pulling me by my cock. I got up and walked out of the room with them. The woman led the way up the stairs and I watched her ass neatly outlined by her tight dress as we climbed the stairs. As we reached the top there was a series of trunks and a notice saying no clothes beyond this point. Before I had a chance to digest this, the lady and mum had removed my clothes along with their own whilst the man had also undressed. Mum placed the clothes into a trunk and locked it, taking the key and fixing it to her chain.

My hard cock was plain for all to see now and I looked at my companions. The lady was very hot. She was average build with beautiful pert breasts. Mum was overweight and her breasts sagged but there was a certain beauty about her still. The man did not have an erection and I felt a little embarassed thta mine was so rock hard. He spoke to the attendant and then led the way towards a bedroom and we all followed. As we walked in, the lady grabbed my cock and said "Me first with this one!" As she played with it between her fingers I started oozing cum and her and the other two started laughing. Mum went over to the bed and laid on her back, spreading her legs wide. "You two had better watch us to see how its done first." She giggled. The man immediately buried his face between mum's thighs and started to eat her pussy. As se did so, the lady wanked me so I came all over them both.

Instead of watching, though, she then knelt in front of me and proceeded to lick all the cum off my cock. This served to reutrn it to its hard state as I watched the stranger move to mount my mum, the lady was sucking my hard cock rhythmically. Mum laughed and said "that's right, David, fuck Sarah's mouth whilst Alan fucks me." She then described as Alan penetrated her, exactly where he was and how it felt. That turned me on enough to cum inside Sarah's mouth and she swallowed every drop. Mum announced that she was going to cum and from Alan's moaning he was there too.

Immediately they were done, he rolled mum onto her belly and mounted her from behind. Sarah stood up in front of me and said "That's the sort of stamina we expect from you soon, David." She stroked my floppy cock. "I hope it will be ready for me soon or you will miss out." With that, she stroked her pussy and then placed her fingers under my nose. "Wouldn't you like some of this?" That was enough to get me hard again and as Alan got busy taking my mum up the ass, Sarah pushed me back against the door and mounted me as we stood there. The door started banging loudly as she built a rhythm and she groaned loudly too. Thanks to having already cum twice, I was able to last the pace until Sarah was cumming and I came too. Alan was next and mum didn't cum this time.

Alan walked over to me and pushed me on the bed with my mum. I then realised they were going to have each other and were expecting me to have mum. In shock I exlaimed, "Mum!" To which they both looked and said "This should be good." and "I thought as much." with a smile. Mum rolled on top of me and mounted me replying, "Yes, darling? Would you like a fuck now?"
