I used to live near Gravesend in Kent, I had a sexy partner who did not know I was bisexual. One day I was on a day off from work and as my girlfriend was working, I decided I needed some fun. I went to the bathroom and removed all of my pubic hair, my 8 inch cock was stiff with the thoughts in my dirty mind. I showered then went to the bedroom. I selected a red, lacy Teddy with suspender straps and a pair of sheer black stockings and put them on, folowed by a tracksuit and trainers. Next I drove to some public loos off the A2 at Gravesend (think they have gone now), it was a truckstop with a cafe and always busy. I went into the gents loos and was lucky enough to walk in as a guy was leaving one of the cubicles. I went in and bolted the door then covered the peepholes in the dor and walls. I stripped to my undies and began reading the messages on the walls as I stroked my rigid cock. I heard the guy next door leave and someone immediately went into the cubicle, I took away the paper covering the peepholes and peered through one. I was not disappointed, the guy next door had already dropped his trousers and pants and was wanking his large cock facing the peepholes. I passed a note over the top of the cubicle, it said, "you have a lovely cock that i would love to suck", he replied "let me see you through the hole", so I stood up to show my undies and hard cock. I wrote "do you like?", he replied "lovely, can i join you?", I replied "tap on door twice when its safe to come in". A few minutes later I heard him tap on my door and I quickly opened it and let him in, I locked the door and stood still as he felt my cock and my stocking covered legs, such a turn-on for me. Next I sat on the loo, he stood in front of me and I held his hips gently, then pulled him forwards and took his swollen knob into my mouth, he groaned quietly and I started sucking him deeply, I glanced towards the holes in the wall and saw a black guy watching me suck the guy with me. This really turned me on as I had never had a black guy and I wanted to see if the hype about big black cock was true. I started sucking the guy faster and stroked his balls and ass, I felt him tensing up then he groaned again and unloaded into my gulping mouth. He zipped up quickly and left as soon as he finished. I passed a note over again and asked the black guy if he liked what he had seen, he replied that he loved it and wanted the same, I told him to come in with me as soon as it was safe. Again, a few minutes later, I heard him tap on the door and I let him in. He was around 6`4" tall, slim and very handsome, when I had locked the door he looked at me and said he loved my undies. I sat down and he stood in front of me, his bulge looked huge through his jeans, he unzipped himself and pulled them down, he wasn't wearing anything underneath and it was my turn to gasp, his cock was enormous, around 10 inches long and thick too! I immediately took as much of it as I could into my mouth, I felt like a horny slut! Then came the shock of my life, he unlocked the door and easily pulled me out into the toilets, there were 5 guys at the urinal who looked around at the noise, when they saw us they all turned to reveal they were all wanking at the urinals. The black guy forced me to my knees and fed his cock back into my mouth, I was so turned on, I didn't care about the audience! Four of the guys came over and stood around us as the 5th guy kept watch at the door, they were all wanking as I sucked the huge black cock, after a few minutes I felt him tensing up, he started cumming into my mouth then pulled out and came over my face. Three of the guys came with him, jetting ropes of cum over my undies and stockings, the 4th guy led me back into the cubicle and locked the door. He told me to bend over the toilet and gave me some poppers to sniff, my head was floating as I sniffed the poppers. I felt him pull my Teddy to the side and heard him spit onto his hand, he rubbed the spit around my hole and without warning I felt his large knob against my ring. He pushed forwards slowly and I groaned as he slowly slid inside me, he began fucking me slowly, gradually easing his cock further inside me, when he was fully in he held my hips and began slamming his cock into me. He only lasted a few minutes before I felt him spasming as he came inside me. After he left, the guy who had been keeping watch at the door came in with me, he knelt on the floor and gave me a lovely blowjob, swallowing every drop of my cum. After he left I cleaned myself up as well as I could, dressed and went home. What a fantastic day!
