So for a headsup on how it happened me and my ex where in what I call semi open relationship since she was allowed to be with other guys or girls I even encouraged her and I wasn´t cause she was extremely jealous and I was fine with it. So this one time she told me to dress up as a security guard (I had a really convincing costume from last halloween) and go to a specific address. She would´t tell me why when I asked her and kept on saying I was gonna love it so I just figured it would be a role-play night. So according to her instructions first I sent her a text telling her I was on my way she replied back with a naked picture of her on the Balcony which at the moment thought she took herself with self timer or something .Next when I got to her building I texted her to say I was downstairs and that I was going up to her apartment she didn´t reply and when I got there the door was open...

First thing that happened is I hear her screaming of pleasure to the pint she was having an orgasm and when I get to the living room surprise !

She literally rearranged the whole place so I could see her get ridden by a stranger , she was on her four getting pounded by a guy and I saw her pussy getting stretched. I got an instant boner and I didn´t know what to do cause she never told me if the guy knew I was coming or not ! After a some 30 or so seconds of enjoying her laugh while getting pounded she grabs the guys face and tells him that security arrived and he could leave.

After 5 minutes or so the guy left and she tells me " ¿Did you like the surprise babe ? now you know what I look like when I´m cheating on you, he was the thief you´re the guard now do your job "

I can´t recall a time where we fucked more and with that feeling of competing according to her it was on her top 3 fucks I know it´s on my top 3 as well.

As a bonus info : That was the first time I "caught her " Cheating and she did it more than 30 times , BEST Experience on sex life I´ve had and actually made me be a lot more secure of myself and so it did for her.

Cheating Story 1 out of 30+ :)
