I'd been with my Pakistani gf for a couple of years, she had the most beautiful long hair, huge big tits and a delicious big bum.

Although I'm white I'd noticed that whenever Zara spoke to a black guy she would play with her hair and become very smiley. I never mentioned this to her but made a mental note.

I had to travel for a few weeks for work so I decided to spice things up I'd get her a black dildo so she wouldn't miss me whilst I was gone.

Zara was very reserved and never really spoke about sex so I wasn't sure how she would react. She sort of laughed it off when I gave it to her as if it was some sort of gag gift.

A couple of months later and no mention of the dildo, I was introduced to one her Asian friends Usma.

Usma was apparently dating a few black guys that she was hiding from her parents. She would take trips on the weekends to go and stay in south london telling her parents she was staying with Zara.

This gave me an idea, the next weekend I told Zara I was working and asked Usma to take Zara with her as she would be alone and needed a night out as she doesn't go out much.

I watched them waddle off on Friday night to the car both in tight jeans and those half jackets women wear.

I told Zara to have a good night.

That was it I was left alone imaging what kind of night she would have.

I woke up the next morning and Zara was still not home. I had a text saying she had stayed the night and would be back in the afternoon the next day. When she got back she looked tired but was her usual sweet self. The very next weekend she did the same thing and this carried on most weekends. She would tell me she had made friends and they would go to restaurants a club and then end up at a shisha place.

By this time I had started seeing someone on the weekends and I eventually ended up breaking up with Zara.

A year or so later I was single again and had been in contact with Usma. We became quite close friends. Eventually I plucked up the courage to ask about those weekends.

I subtly dropped in conversation that she was a very sweet gf and so innocent.

Usma gave me a look that said otherwise.

Turned out they weren't going to any of these places but rather to a house full of black guys that they would both suck and fuck all night.

Usma told me that Zara would often suck off the biggest black guy in his car and then would go back to his house and get fucked in his bed. Eventually the black guy started to invite his black mates into the room to fuck her. She said Zara was one of the biggest black cock sluts she'd ever seen. I couldn't believe my ears.

My dick had never been harder.
