The story I am about to tell happened around this time three years ago. My partner got this thing in his head about swinging,And was always finding. Ads from couples who felt the same as him, I cant say I was against the idea, To cut a long story short we met a couple and we had sex with each others partners. Afterwards we both admitted we hated the fact it had happened. A lot of jealousy came into it but we got through. Mainly because it was not like a affair and we both knew what we was getting into.If anything it made us stronger. At the time I was working as a bookeeper for a small company not far from where we lived. Most of the guys that worked there were young black guys. Because I was in the office we never really came into contact with them. But our office overlooked the yard and loading bay, So could obviously see them obviously working or kicking a ball around during their breaks. The girl I shared the office with was also black, I cant say we were close friends but working together so much we did talk openly to each other. Then one day I made an innocent comment. And her reply shocked me, I caught sight of a few of the guys kicking a ball around during their break, It was summer and the guys were all stripped to the waist. I jokingly said, I best come away from this window as those guys are getting me hot. Without smiling and in a Jamaican accent, she said never let a black guy stick his ting in you. The "Ting" made me laugh as she had never used the accent before, Seeing I was amused she said I am serious, Those guys just want to knock you up, Your just a trophy to them. When I pressed her about being so defensive. And said if that's the case how come your boyfriends black if they are that bad. She said they don't treat us like that, You let a black guy fuck you. He will brag about it. And if he knocks you up. That's even better for him.As I had no intention of fucking any of them the conversation finished. And I never gave it another thought. I suppose some would say the next chain of events were fate. But around October my partner and I decided I should come off the pill. Not so much to try for a baby, more of if it happens it will happen. My company does not have Christmas parties as such. We just finish on the Friday lunchtime and they provide some food and drink. The music goes on and that's it really. The previous year I had one drink and left, Not because I was a party pooper, But I did not really know any of them. Only this year my partner had gone away for the weekend, So I had nothing to go home for, and one drink lead to two, And yes I was enjoying the male attention, But was also aware as there was only five girls there it was not exactly a compliment. I was a little tipsy but still fully aware of what was going on. As I left the toilet I was confronted by one of the guys holding a bit of mistletoe above us, demanding a kiss something that was probably happening all over the country. As I offered him my cheek he suddenly kissed me full on the lips. I don't know why but we just looked at each other then moved in for a full open mouthed kiss. As we kissed not only did I know this would go further I wanted it to. I could feel his erection against me through his clothes, And by now all sensible thoughts had gone.I felt his hand go under my jumper and cup my breast, I can remember saying not here, Take me home, As we entered my flat we was to carried away in lust, I just lead him to the bedroom, I am not saying I have not been around but even I cant remember acting like this before. Soon we were both completely naked and I saw his black dick for the first time, and I just wanted to touch it for some reason, In my mind I thought as it was black it may feel different, I really don't know why. I do give oral, And quite enjoy it once its started But it is not something I play the lead role in giving, But for the first time in my life I actually moved to take him in my mouth, I tasted the saltiness of that little bit of pre cum men have and knew it would not be long before he cum fully, And I wanted him inside me, so moving fully onto the bed I opened up for him to enter me, I can remember though saying don't cum in me, But as soon as he began to thrust into me any fears I had just went,I have to say I don't know if he was just good or if it was because I was being fucked by a black guy, or just the circumstance in how it happened but the sex was amazing. I had never felt pleasure like it before, And suddenly with a final thrust he came deep into me. This would normally have made me angry, But I was so satisfied that I could only lay there as he went soft inside me. I am going to be honest here, sex with my partner is good but once is enough, Yet this was different I wanted it to happen again, And he did not disappoint me. Within minutes he was hard and inside me again and taking me to a place I had never been, And somewhere I did not want to leave. I am fully aware it was lust, But just for those few minutes I was in love I wanted him to cum in me I wanted his baby as crazy as that seems. And for reasons I cant describe when he did cum I was willing for his sperm to hit the spot. we kissed for a while and drifted off to sleep. I woke up early and looked at my lover beside me sleeping, And all I could think about was the amazing sex we had the night before, I should have felt guilt but did not. I got up to make coffee and on checking my phone. I had a message from my partner, saying your probably in bed feeling lonely We are having a great time. Try not to miss me to much. I rather wickedly felt like texting back, In bed but not lonely or missing you. I brushed my teeth and took the coffee back to the bedroom where by now he was awake.He pulled back the quilt, and motioned me to join him which I did. Looking back it could be said I had an excuse for the night before as a lot of alcohol had been drank. But I had no excuse now, And I knew I wanted sex again. Which we did and it was just as amazing as the other two times. Again he made no effort to pull out of me cumming deep inside me, which the time I actually wanted him to. We just lay there in each others arms, Until finally he said he had to go. He dressed and left as quick as that, we never swapped numbers just see you at work. I just laid there thinking of what had happened the night before. But at no point did I think he may have made me pregnant. Going to work Monday was not easy. And my worst fears was confirmed as I entered the office to see Julie just shaking her head. I could only say who knows, And she replied I warned you everyone. Then she really hit it home to me when she said did you use anything, she obviously knows I stopped taking the pill. I admitted no. She then said so you want a black blokes baby, Because he would not have been careful. I felt like a child being scolded. Again I said no, And in a more sympathetic way than sarcastic, she said well think ahead as pregnant you will be. Its always the way. And I knew she was right. I had a worrying Christmas as I had by now convinced myself I was pregnant. Fortunately I was not. I have never strayed again so far. But do sometimes think of the amazing sex that night. I cant see my relationship ever ending. But if it ever did I have to admit I would probably go down the black guy route.
