I was 18 yrs old,it was'nt fashionable to admit to being gay,it was actually risky.I was obsessed with wanking but only in the private.I did'nt have a clue about sex in public toilets,I lived with my mum,there was just her and me,I was'nt much of a mixer.Why I went in the toilet that day I have no idea,it was empty,I went in the middle of three cubicles,it was the first time I'd come across that kind of grapfiti. I was'nt expecting it to turn me on the way it did,I startd to wank myself looking at the drawings of cocks spunking and reading the stories of men wanking or sucking each other off,it was completely shocking but also getting me so sexually aroused it litterally changed my life. At first I was just standing there with my pants and undies around my ankles wanking in a way I'd never done before.At that time I had no idea how long it took other men to wank themselves off,I did'nt know that I had a condition called delayed ejaculation which meant it sometimes could take up to 40 or 50 minutes constant wanking to get myself to spunk. Suddenly I was'nt satisfied with just my pants and undies down I wanted to take them off,I did and got myself even more aroused,my shirt and vest was next,it was as if I'd become a totally different person,I was standing there completely naked,the fact that it was still a public building and the danger of being caught did'nt even matter to me,I think for the first time in my life I wanted to be seen naked and wanking. The lock on the door did'nt work,a fact which did'nt matter when I first went in the cubicle and which I'd now in my sexual state was completely forgotten.When he pushed the door open and looked at me naked and wanking,I completely froze and for some reason that to this day I,m not sure of what happened next,I don't know if I made an attempt to stop him coming in the cubicle or I willingly let him come in,but either way he was in there with me,he had already removed my hand from my cock and he had started to wank me and I let him do it. I remember him sucking on my nipples as he held my arse in one hand and wanked me with his other,then he was on his knees holding both cheeks of my arse in his hand and my cock is slready in his mouth,the graphiti that had started the sequence was real life and I was making no attempt to stop any of it happening. As he sucked on my cock he undid his own pants and took his own fully hard cock out and started to wank himself,my eyes were glued to him doing that,I would'nt have thought it possible but my own sexual arousal was even increased by his hand moving up and down his cock. His sucking on my cock became more and more intense and of course I know now he was wanting to suck me off,but because of my issue with delayed ejaculation I was still just in a state of utter sexual abandon and the more he sucked the more I wanted him to keep doing it,even when somebody pushed the door part open and could see what was going on it did'nt phase me,I even enjoyed it. When I saw his first spurt of spunk shoot from his cock I was really surprised,was he coming off already,but I'm afraid he was,he was covering his pants in his own spunk.I was gutted when he stopped sucking my cock,but he just left me standing there naked and frustrated and he was gone. It was my lucky day,the chap who'd looked in on us earlier was waiting in the wings,I definitely made no attempt to stop him joining me,he wanted propper sex,it was'nt just grab and wank,he stripped off naked,he had all the neccessaries with him,condoms,KY, he fucked me,he left the gear with me,I was a bit sore for a couple of days afterwards,but I know that at least tree others fucked me before I eventually manage to spunk,and did I spunk.
