[M/F] - My girlfriend's best friend. | 2016

I have to admit though, a reverse cuckold situation where I am dominating someone in front of my girlfriend is something that has ALWAYS been a fantasy of mine, but I've never had a girl interested in sharing me enough to do it. This is the closest experience I've had to that 'fantasy'.

I was dating a girl and she asked me to try and fuck her best friend. I wasn't really attracted to her friend, she was the principled moral types who really don't sit well with me (I am abrasive and a 'ends justify the means' type).

She challenged me, said I couldn't do it even if I wanted to. I hate being challenged like that. I decided to accept her challenge, and I attempted to rise to the occasion. I systematically wove my way into her friend's life - showing up at mutual parties I'd usually skip, going to group dinners and making sure I'd sit next to her - that kind of thing.

It took about three months to make any progress and my girlfriend and I weren't talking about the challenge anymore. At that stage, she believed she won and told me it would never happen... But it wasn't over yet.

It was June last year and it was fairly cold. My gf was working until 9 and then she'd probably head to hers and pass out. I was chatting to her friend when she mentioned she was house sitting. I jumped at the chance and asked her if she was having any parties while they were away.

She responded that sadly she was not, but she'd be keen to have a few friends over for a few drinks. I then asked her how it was spending a night alone in the house and she said it was a bit daunting. I replied with something to the affect of 'well I'd keep you company but ya know, I'm with Melissa'.

She responded 'No that's fine, if you came over we'd just be hanging out as friends'.

I was in. I got excited and responded 'yeah sure that would be fun actually, I'll head over soon'.

She flicked me the address and I was at some strangers' house at 9pm on a Thursday night. I walked in the door and she was wearing her night gown. My eyes popped looking at her, although her face was fairly plain, she had curves in the right places. Her breasts poked through the black silk. It was easy to see that they were a solid C cup. She had a very small frame and it made them look fairly large. Her legs were the perfect length for her frame and they were a nice, bronze colour. She may as well have been naked. Needless to say, I was in heaven.

I didn't hesitate. The dressing gown told me all I needed to know. I leaned in for the kiss, I wanted to see what would happen.

She launched at me. We tore at eachothers clothes like animals. Her clothes dropped quickly but she was just as adamant to have mine removed. When she tore my shirt off, she saw my chesthair. She ran her fingers through it and looked me in the eyes and begged me to fuck her.

We skipped foreplay. I turned her around and pushed her against the wall, spreading her legs right there in the hallway. I did not put on a condom and I entered her with such a vigor that I swear the street heard her moan.

I whispered in her ear 'you are my fucking whore'. As soon as the words left my lips she started shaking, her knees buckled and I had to hold her hips up. I started thrusting into her as her body shook and she started to shudder.

I wish I could say I was some kind of god, but the experience was too much. I thrusted into her for maybe 10-15 more seconds and then I was finished. I came all over her tight ass.

She looked at me quite scared, not knowing about my gf and my bet. I told her it was okay and it would be our little secret. We spent that night and many others together - I never told my (now ex) gf that I won the bet, to this day she believed I lost.

Oh well. :P
