I'm a 21 yrs old male but I'm often thought to be younger.I'm just 5'3" and fair haired,I knew from an early age that I was homosexual and as time went on became fascinated by undies.I also became besotted by stories about public toilets and gloryholes but until recently had never come across one.I've got a job travelling for a company and when I was near Hull a couple of weeks ago I came on an old looking toilet.I did'nt know if it was even in use,it was pretty grotty inside but was still in use. There was 3 cubicles on the back wall,all the doors were shut,I was unbelievably nervous but tried them,the first one was locked,the second one was unlocked and the door pushed open,there was a chap standing inside,he was wearing a bra and a little pair of knickers,he was wanking himself and made no attempt to close the door,he just stood there and let me watch him wank,he was about 60 but had a nice body,right away I was getting a hardon,there's nobody next door he whispered indicating the third cubicle. I pushed the door and he was right it was empty,I could see my first gloryhole,there was a couple of bricks missing from the partition wall.There was'nt a lock on the door but right then I could'nt care less,all those stories of toilet sex was coming true.His face was already at the gloryhole.I don't think I'll ever again get such a buzz as I started to undress,it did'nt even occur to me just to take my cock out,I did'nt think I'd ever be doing something that when reading the stories turned me on more than anything else,being completely naked in a public toilet and like in the stories being watched and played with by another man wearing just girls bra and little knickers. When I was in just my own undies,which I've been getting from an internet place,I was wearing a small satin G-sring,my cock was bulging and throbbing inside them,but before I could take them off he was already playing with me through them,the front was already becoming wet from my precum. I pushed them off to let him have full access,he drew me towards the gloryhole,I knew he was going to suck my cock,I pushed myself as far as I could onto the partition letting him having as much of my cock as I could,I felt the wet heat of his mouth as he sucked my cock in and out of his mouth,it was everything and more than I'd ever imagined,I knew then why so many men miss gloryholes,having your cock sucked by a complete stranger in a grotty public toilet is mindblowing. Even when the door behind me was pushed open and I could see a chap,again probably in his 60s,watching me,his cock out of his flies,still soft but hardening as he wanked it,yes,yes,yes,.I did'nt need to ask him to come in,he was already in and taking his clothes off,he was'nt just breathing he was gulping air,I knew he wanted my body. His cock was larger than I'd expected,it did'nt look a lot when he first took it out but now that he was naked and wanked himself fully hard it was impressive.My own balls are small and tight his were big and low hanging swinging with every rub of his hand on his cock. He gripped me from behind and I could feel the heat and power of his cock as he pressed against my back grinding his cock onto my cheeks.His hands were around me gently tugging on my nipples,all the time my cock being deliciously sucked by my next door neighbour.He wanted me all to himself and gently pulled me away from the gloryhole,my cock feeling cold as it left the heat of the hot mouth,but within seconds it was back in another equally hot mouth. I felt a twinge of guilt about abandoning him next door,but I did'nt need to worry ,within minutes he was joined by another man who was also quickly naked.This was it this was what I'd read about so many times,naked men,men in sexy undies,the chap with me asked if he could put my G-string on and asked me to play with his cock through them. I was'nt expecting him to spunk so quickly,but I felt him suddenly tense and then the first spurts of spunk into my undies,he made no attemt to stop himself,he emptied himself into them took them off and used them to squeese his cock dry,I would'nt be wearing them again. Within minutes of him leaving my cock was in another hot mouth.
