I was only 19 at the time, I worked away from home with a good bunch of lads shop fitting,We worked hard through the day then returned to our B&B in the evening to shower then go out for an evening meal and a few pints, This one evening after our food and drinking quite excessive we returned to our B&B,We all went our separate ways back to our rooms, We didn't have the luxury of en suite bathrooms so had to use the communal one on the landing, I got up about 6.30am as I needed to take a pee, After using the bathroom I headed back to my room, As I opened the door I noticed a guy laying on the bed, I stood looking at him thinking who the hell is in my room, I then realised I had walked into the wrong room,Bit Confused but this guy was laying on top of the bed and not actually in it,To be fair it was summer time and very warm, I guess he was in his early 30s,He had a great toned body and smooth brown skin, He was laying there in nothing but his pants, I couldn't take my eyes off him,Not sure why but looking at his smooth body I was getting very turned on,I was admiring his body and the bulge in his little black briefs, I was about to leave the room and reached for the door handle, At that I heard the guy groan and it looked like he was smiling slightly, He moved one hand down to his briefs and rubbed his cock, My stomach was doing somersaults and my cock was getting hard, I watched him rubbing his cock through his briefs and he was groaning, Not sure what come over me but I walked towards the bed and gently put my hand on his belly just above his briefs, He raised both hands and placed them behind his head all the time his eyes remained shut, I took that as a welcome, I gentley stroked his stomach then moved my hand onto the bulge in his pants, This was the first time I had ever touched another guy's cock, He felt very well endowed and was getting harder by the second, I rubbed his cock through his pants very slowly, He gave out a few groans of appreciation until his cock grew so much it escaped from the top of his briefs, I bent down and kissed his tip,It just seemed like the thing to do, I had often watched porn films with my girlfriend and had to confess to her that when I watched the woman sucking cock I got very turned on, Firstly by the woman giving the pleasure but also by the sight of a nice cock, She liked my honesty and said you should give it a go, I then licked his tip and knelt down at the side of the bed, I grabbed hold of his briefs and pulled them down to reveal a huge thick cock, I wrapped my hand around his tool and guided him into my mouth, He was rock hard but it felt thick and soft in my mouth, I very slowly sucked his cock while gently tossing him and his groaning was getting louder,My stomach was in knots at was I was doing and I was very close to Cumming in my pants I was so horny,I could feel him twitching in my mouth and he cried out I'm going to cum,I kept my mouth wrapped around his bell end and continued to jerk him off till he exploded in my mouth, As he came so did i, Even without stimulation to my own cock, I felt him hit the back of my throat and I swallowed as much as I could, He was a very heavy cumer so what I couldn't swallow escaped from my mouth down his cock onto my hand, I forced my cum covered fingers into his mouth which he seemed to enjoy, I then got up and left the room, I went back to my room but couldn't sleep for the excitement I had just experienced, At the end of the week when I returned home I confessed to my girlfriend what I had done and she was shocked but also very excited and turned on,She insists I need to do it again while she watches
