I've been going out with my girlfriend for 5years now and have not been tempted to cheat on her once with another girl. She's gorgeous and has a cracking body and we are very much in love and have we have a very active sex life.

However!...... Recently for work I was sent on a training course in Scotland for 2 weeks where I had to stay in a hotel for the duration.

It all started very boringly, the usual crap on training courses and after having a heavy night drinking at the hotel bar and depression of 2 weeks without a play, I decided to pretend I was sick, not go to work and relax in the pool and jacuzzi on the last day instead. I was happy to see that I was the only person in the pool area and spent 20minutes in the jacuzzi on my own. Then suddenly I heard the sauna door open and a well built muscular black man got out and started walking towards me.

He got in and after a few minutes of the awkward silence we started having a chat.

He told me that his name was Chris and he was a part time boxer from London and he had come up to Glasgow for a job interview somewhere.

I was glad no-one else was there as I felt a bit intimidated as I am a slim 10st in weight white lad and he looked totally chiselled and was about 14stone of pure muscle. Maybe it was just my masculine pride. We then decided that we'd go and get showered and get changed before grabbing a few beers for the evening. We got to the changing rooms and I looked through my bag for my towel, when I turned round Chris was brazenly standing there texting someone on his phone totally BUTT NAKED apart from a hotel towel over his left shoulder.

It was impossible not to notice his thingy as he stood there in front of me. Now I've never had any problems or complaints from my girlfriends with the size of my length 6half inch's according to my missus But I was staggered by the size of his length. I quickly looked away as soon as I had seen it, but decided to have a discreet second look, just out of curiosity I guess. I 1st looked up at Chris' face, but he was engrossed in sending his text message, so i decided to have another look at his length. It was a few inchs bigger than mine and was extremly thick too. I must have been gawping at it for 4 or 5 seconds before I hurriedly got my things and as calmly as I could, said to Chris i'd meet him at the hotel bar in an hour & went up to my hotel room to get changed & phone my girlfriend. After chatting to my girlfriend for 30mins I started to realise how much I missed having a shag. I went to the bathroom and whilst preceding to have a pull whilst viewing a few sexy pictures on my phone that I had taken of my girlfriend previously. However half way through I kept getting images of Chris's length in my mind and started dreaming of getting on my knees and sucking him off. Just before I was about to cum however the cleaner knocked on the door and I lost the image in my head and suddenly started feeling a bit weird about what i was doing and pretended it had never crossed my mind. I got dressed and when down to the bar. Chris was already there fully clothed thankfully and we began to down a few beers, flirt with a few barmaids and chat about all the things blokes do football, politics, girls etc and after 4 or 5 hours we were a bit sozzled and went out for a few more drinks on the town. We got back to the hotel room just before last orders and we decided to get a bottle of wine and go up to Chris' room and watch a film.

He got into his bed and took his shirt off and I lay on my stomach on the end of the bed facing the tv. There was a sex scene on the tv and it got us talking about sex for 30minutes or so, favourite positions, different girls we've played and so on.

I even felt brave enough to show him the naked pictures of my girlfriend on my phone and he showed me a few dirty pictures on his phone of girls he'd previously shagged.

The film we were supposed to be watching and whilst channel hopping, Chris said he was going to pay for the porn channel that was available and we both got comfortable and started watching it. It was a lesbian scene that was going on and there were two gorgeous british girls going at it. Gradually our small talk began to stop and I felt myself getting a serious erection whilst I was watching it.

I then began to hear some grunting to my left and noticed chris' arm going up and down under the sheets as he was obviously pulling himself off. He looked at me and asked if I was getting horny too.

I just sort of gulped and said yeah. Suddenly he pushed down his sheets and revealed his huge member as he slowly masturbated it. For some reason that seemed to make me even hornier and I seemed to be looking at him rather than watching the porn on tv. For some reason I happened to comment that he had a huge length and that I bet the girls he's been with have loved it. He told me to feel free to start pulling too and so I did.

I felt a lot more comfortable than I thought I would pulling with another man.

I still kept finding my eyes wandering to his enormously fat black length as much as the two horny girls on the tv and after a while Chris' eyes fixed on me.

'You like my length?' I remember him asking. I just nodded and looked back across at the tv. I suddenly felt a shiver accross my body as I found that it wasnt just my hand on my length, as Chris' large hand removed mine and he started jerking me off slowly himself. my body froze, but if anything my erection was getting harder by the second. 'Do ya wanna do the same to me' he said 'Or would you rather use your mouth?' I immediatly started pulling him too as I looked in the reflection in the mirror of us beating each other off and felt myself about to explode my cum. Suddenly he stopped pulling me off and gently put his huge paw around my head and whispered, 'Suck me!' 'I want you to make me cum in your mouth' I still had his mammoth length in my hand without even deliberating, I moved my head down to his midriff and started to toy his shaft. With one hand I cupped his balls with my other I felt myself rubbing his groin. I then began to put his helmet in my mouth as I felt myself slobbering down his length and was quite surprised how much of his huge 9" length I could take in my mouth as I worked him off, occassionally I would stop and pull him for a bit before gobbling him a bit more.

I think I had been doing it for about 9 or 10minutes before I heard his breathing and grunting getting more and more loud and suddenly I could feel his leg tighten and his head move down from the back of my head to the back of my neck, as I suddenly got a huge warm shot of spunk down my throat, I had a very brief urge to gag before suddenly I felt a few more big shots of hot cum hit my face. Suddenly I felt myself being pushed onto my back and Chris saying, 'My turn', as he started doing the same to me. I think it took me all of about 5 minutes before I came. All over his chest. Gradually our breathing slowed down and my heartbeat began to slow too, from all. my recent excitement. I didnt know what to say, and just decided to make some pathetic excuse that I had better get back to my room and text my girlfriend.

We arranged to meet each other for a few drinks before we left the next day, but in the morning I decided to check out early and make my way home. It initially left me witha sense of guilt and I wondered why I did it, but the more I think about it, the more it turns me on and makes me want to do something similar again. I still prefer sex with my missus. But I think a discreet bit of bi fun every now and then could be a distinct possibility. Wish I'd got Chris' number!
