This is a genuine account of an experience i shall remember forever and which infact started myself on the road to explore my bisexual side ....... At the time i was 34 yrs old, single and over the previous 8 years had started showing an interest in naturism, this mainly came about when i booked a holiday alone after previously splitting with a girlfriend and went naked for the first time on a Greek beach and found the whole experience so very natural and perfect in every way, i therefore chose to spend holidays always on a nudist beach and discovered when at home naturist spa's. So, at the age of 34 i had been many times naked on beaches and in spa environments, i headed to inner London and fancied attending "Rio's", the weather was wet and windy so entering the spa gave me a lift, the great atmosphere made you forget where you were and how dismal the day was ...... i removed my clothes and placed them in the locker and headed for the sauna, i left my towel outside and sat naked on the bench seats...to set the scene i am of medium to large build, fairly well toned and my cock and balls are shaven apart from a small tuft of pubic hair above my cock, my balls are quite large and when erect my cock is only just 5", not large but have been told on several occasions it is good looking, that's fine by me ! So i was sitting in the sauna enjoying the warmth and totally relaxed, there were some other guys in there as well as other couples coming and going, 20 mins later i had had enough heat and headed to the showers, i gave myself a good soaking and then entered the large jacuzzi, again there were people of all ages and size milling about in the spa. I glanced up at a couple who were about to come into the jacuzzi, they caught my eye for 2 reasons, the lady, about 26 yrs old was very tall, medium to large build but very well proportioned, she had her hair tied back into a pony tail drapped to one side, she wasn't naked though, something they do allow at Rios, funny considering it's a naturist place , anyway she had a black all in one speedo swimming costume, she looked very sexy and i could see as she stepped into the water a perfect "camel toe" on show , it protruded from the clinging material and seeing this made my cock stir, she looked so gorgeous. I did say there were 2 reasons why this couple caught my eye, well secondly, the guy, roughly the same age as the girl was naked and well toned and fit, but the guys cock was enormous, it must have been about 7" flaccid and was very thick in girth...he almost got into the water in slow motion so everyone could admire his very large penis... About 10 to 15 mins had passed and there were about six or so people in the jacuzzi, a space became available next to me as another couple had left and the two mentioned couple adjusted their positions and sat next to me, no words were exchanged just glances every so often. The lady was right next to me and the guy kept holding her hands and was drifting slightly in the water , pulling himself close to her then pushing himself away, i was watching them quite intently and also i couldn't take my eyes off of her erect nipples which stuck out from her costume, they were so gorgeous. The watching and the heat from the jacuzzi as well as the jets of water bubbling around gave me an erection , every so often i would gently masturbate , very slowly as i pulled back and forth my foreskin, the guy had let go of the lady's hands and was nearly directly infront of me, the atmosphere felt electric and for some reason quite charged, it was at this point, was i imagining it or did the lady move closer to me ? She had and now her body was pressed against mine, i could have reached out and held her tightly, she was so very sexy, i was very erect beneath the water and my breath shuddered as i felt a hand slowly work it's way up my thigh, gentle finger tip touches until my balls were stroked and the hand grasped my erection and began to slowly masturbate me....oh my God it felt so fucking horny, the lady turned to me and gently whispered " let's all go to the restrooms " ......as she stepped away and towards the steps i realised one thing, my cock was still being played with, yes, the guy who i almost forgot was there smiled and gave my cock one last stroke as he too moved towards the steps......As the lady got out of the water her costume was like a second skin, her nipples and camel toe looked so edible, i emerged from the water with an erection for others to see, by this point i was so horny and didn't care who saw me, last out of the water was the guy, well, the admiring glances from others were soon diverted from me as he stood there with what can only be described as a massive erection, his foreskin was peeled back and the large glistening head stood proudly above his 9" cock, wow i was very impressed and also couldn't take my eyes from this amazing throbbing penis.......... Still extremely excited we entered the restrooms but there was a twist in the scenario, the lady pulled me close to herself and gave me a cuddle, the guy stood close to my side with his erection pressed against my thigh ! She gave me a kiss on my lips and smiled she asked me had i enjoyed my cock being played with by her guy ? i said yes and explained how sensual it was and how i had been admiring her, she thanked me and again smiled, by now my cock was being masturbated by the guy as she held my hands, i leaned towards her and she turned her head to one side and said she needed to tell me something, what could it be i wondered as my cock was being masturbated faster................... I was not shocked but still very very horny and extremely aroused, but she explained she was a lesbian, they are friends and nothing more but she wanted to see her good friend, with her help seduce a guy and watch them ejaculate .....i was still excited, slightly disappointed as i would have loved to please her orally and hold, pinch, kiss and lick those so very sexy nipples, again she smiled and kissed me on the lips. She was still in her swimsuit and after she kissed me she held one of my hands and guided the other onto her breasts, i was stood there as the guy knelt down and began sucking my cock, her eyes were transfixed and as he sucked and wanked me she gently rubbed herself with one finger which crept into her private camel toe, this was so much, i tensed up and sensing this the guy moved his mouth away and masturbated my cock furiously and she watched as she held my hand tightly ejaculate jet after jet of hot cum, she grinned from ear to ear and held me close to her, she was so fascinated and pleased. I now said to her that she still has to watch another cock ejaculate, the lady and myself stood together arms around each others waists as i reached out and held this massive erection, i teased his balls and ran my hand up and down his shaft, within no time at all pre-cum glistened around his swollen gland, i picked up the pace and his balls tightened up and with a last intake of breath he ejaculated, she again watched with excitement , pleasure and satisfaction..........this is a true account and one which excites me even writing this some years later, i would love a repeat performance !!
