I have changed my name so friends do not recognise my story. Last year I celebrated my 18th Birthday in May. my boyfriend of 4 years I will say his name is Alex bought me a very expensive photography session for a boudoir shoot. I had only lost my virginity to him on my birthday even though we had been indulging in sessions of exploring each others body for two years. we went along to meet the two photographers both women before the session so that the could explain to me what would happen and the showed some shots from previous customers and I said that I am really plain and could never look like them. I am 5' 9" tall size 8 with light auburn hair. green eyes and very pale skin and 32c bust. I also have a very natural pubic are after being told that the session would last for at least 5 hours which would include professional make up and hair styling. The session was booked for Friday 31st may 3 weeks after my birthday. They recommended that I had a Brazilian wax a week before the session which they could arrange at a discount so it was booked for 7.00pm on the Thursday before. Alex was then invited in as we discussed how many costume changes i would want and what to wear it was decided that I would wear white bridal type underwear including uplifting Basque stockings and garter and also white and black nightwear they told me if there was anything that I did not already have they had a good supply in my size but I would have to bring my own knickers. I was advised not to wear a bra on the day as if it was too tight it would leave marks on my back. i had the Brazilian and was left with just a thin strip of hair above my vagina and Alex couldn't keep his hands off me and i actually spent the weekend with him and actually slept at his house and had sex every chance we could. I agreed with Alex to allow him t come to the shoot as I was still very shy and a little apprehensive but he had spent a lot of money for these pictures. The night before the session I had been asked to attend the studio for a full body spray tan I had booked Friday as a day off from work and Alex picked me up at 0800 and we set off for the studio Alex handed me a bag as we parked up containing several pairs of knickers incl. thongs. Shorts two pairs of PVC crotchless . Alex was shown to a room next to the studio and it was explained what would happen as he was with one of the photographers I was with the make up artist and stylist I was sat on a chair in just the loose fitting almond shorts . I was then taken into a small room and asked to remove my knickers and was then the results of the spray tan examined . i then went out side into the actual studio where behind a screen were hung all the clothes that I had brought plus a selection of what I would call exotic underwear. The session got under way and I didn't even think of where Alex was the camera was clicking continuously as they called their assistant to readjust my body and clothing and I was shocked that it was a man of about 50ish.i was really getting into the session and enjoying the attention and soon realised that i was showing quite a lot of bare skin it was then time for the first wardrobe change and was told to change into the bridal nightwear plus white hold up and garter. I was told to lay on the bed and the assistant helped me to get into the position required . I was the asked to remove the nightdress and just wear the negligee Then lots more pictures and then the negligee was lowered to expose one breast. I was the asked to remove my knickers and to stand leaning against a post with my head leaning backwards then I felt the negligee being opened but was caught up in the moment.. then everything stopped and the assistant moved a screen to expose a bar area and Alex was sat there with a pint in his hand and a table full of sex toys which unknown to me he had bought and brought with him. Up to this point I have never even touched a sex toy before never mind using one. I was shocked and looked at Alex and he just quietly explained that the session is almost over but they could take some more explicit photos if i wished. After the break and another costume change we carried on with the shoot and finally finished and i had loved every minute of it even the fact that I had been exposed to a strange man older than my dad. As I went behind the screen Alex followed and asked if I would have some explicit ones taken and eventually I agreed and he helped me into a PVC bustier which pushed my breast right up and my nipples were both clearly on view then he handed me a pair of the crotchless knickers. As I walked from behind the screen a bed had been positioned in the middle of the floor and the table of sex toys and a tube of lube next to it. the assistant was no longer to be seen i was told he had gone and would only return after we had left Over the next 90 mins I experienced several new things i had my bottom lubed and a but plug inserted and blown up and at the same time i was laid on the bed and one of the photographers gently inserted a rabbit vibrator inside me and positioned the ears at my clitoris and Alex was laying on the bed and gradually fed his erect cock into my mouth I had never done this before but he was soon fucking my mouth and at times i was gagging before i felt him shoot a load of spunk down my throat and i almost chocked before swallowing the lot. As he stood up I realised that the camera was still clicking but both photographers were now naked and were licking my tit and nipples and around my vagina as I started to have a massive orgasm soon everything was removed and the I was turned onto my belly and one photographer slid under me so that my face was pushed into her cunt and the other one was under my bottom sucking and licking me I then felt the butt plug deflate and be removed and realised that Alex was now fucking my arse. Eventually the session came to an end and i was shown to a shower room where Alex and i both showered. and dressed. as we came out the two photographers were looking at their laptop then i heard a cl8ick and Alex was handed a 2 x CD's and made arrangements to call them soon with our order. We arrived home and i said " What have I just done." Alex said if you want you can see as i have it all on CD.we got ourselves a large G & T and settled down and was shocked as i saw my bottom having lube worked into it then the but plus inserted before being pumped up and stretching my bum hole The I saw my lips parted and could see inside my vagina as the Rabbit vibrator entered and turned on . we had fantastic sex four times before we decide it was time to go out. On Saturday we got up and I was really sore as we spent all night having sex till we fell asleep .we looked at the cd of the photos and decided we wanted 40 prints including a large one of me in just the negligee when my nipples were pressing against the material and my slit could be seen through the gap we wanted enlarging so that when we got our own place we could have it over the bed. It was September when we finally moved into our own house on a small estate. and most houses were occupied by young married couples and a few with children. Alex was soon friendly with a few of the men but I was a few years younger than most of the women but was invited out one Friday and was accepted as one of the crowd but knew that something was being kept from me as I kept hearing some whispering about asking me. Then in November last year i was asked by Melony if I would be interested in attending one of their adult parties with Alex. I just said I would get back to them. That night in bed I broached the subject with Alex and he was surprised i was interested and I couldn't understand why. he then explained that he had heard that several couples participated in swinging parties. and if i wanted to go then fine we would do he then had to explain to me what a swinging party was. I was shocked but he did seem interested so told him if he wanted to I would try it once. So two weeks later we got showered and dressed in St Trinian's outfits Rob Came into the bedroom lifted my skirt before teeling me i could not wear a thong so I changed into a pair of the black PVC crotch less knickers instead. and made our way to Marion and Rob's house we got there the furniture had been moved to the walls to leave the floor free and a twister game mat placed on the floor When everybody had arrived we all assembled in the Conservatory where a buffet was laid out and in the kitchen was all the drink. Rob then said " Ok the rules for tonight is anything goes there are 6 couples and 4 bedrooms plus two mattresses in the dining room. for the benefit of Miranda and Alex just a few rules on St Trinian's nights any naughtiness is punished with corporal punishments. Drop any food on the floor and I will smack the back of your legs knock over or spill any drinks and it is the paddle over knickers or boxers any breakages is a caning and attempt to cheat at games is a caninig .Anything not in the spirit is again a caning at the end of the night everybody gets a caning we all started mixing and having the buffet when there was suddenly the sound of somebody get their legs smacked followed by a few yelps . Samantha soon came through with several hand prints visible through her stockings. Next we heard a shout and Rob opened the under stairs cupboard and removed a trestle before telling Sean to assume the position as he bent over the trestle Rob fixed the straps on each leg of the trestle around each ankle and each wrist he then lowered his short pants before giving him 6 hard slaps with a leather paddle. he was released but was soon rubbing a sore bottom. Rob was laughing so much he dribbled some drink onto his shirt and was ordered over the trestle and received 6 very hard smack with the paddle. Then Rob announced game time and we assembled and started to play twister all the women were soon displaying their knickers and I noticed that three of us had crotch less knickers on on my third go I fell over and knocked rob of the mat and was told to go over the trestle As i did so I was fastened in position and was the told that I would receive six with the cane and then accompany rob upstairs for 30 mins as he was the injured party. Then my bottom exploded in a line of fire I was screaming after 4 but then realised that I was being released and led upstairs As soon as we were upstairs my shirt was opened and rob had me on the bed and was sucking and biting my nipples before directing my onto all fours and was soon entering me with out the need to remove my knickers then just as I started to have an orgasm i could feel him stiffen and knew that he would soon be emptying his balls into me then his warm come hit deep inside me. I heard some body shout time and as we returned downstairs I was told to take up my position on the twister again and I then could feel Rob's spunk start dripping out of me. Over the next 6 hours i was caned again and had sex with all the other guys there and Alex had sex with all the women . At the end of the night everybody got 6 of the cane on the bare bottom.as we left I looked at the clock and it was 7.30 in the morning. as we got home the phone rang and it was rob to say that Samantha had forgotten to give us and invite for her party in three weeks time. In bed Alex asked how I was and said apart from sore I don't know but I enjoyed it.. More parties soon followed
