One of my many turn ons are female cosplayers. I love it when they wear skin tight costumes. So you can imagine my surprise when I peered through a gap in the curtains on a ground floor flat and saw two people dressed as super heroes. At first, they looked like they were about to fuck in their living room, not releasing that I was peeping. But for some reason she started to get a bit angry with him. I was gutted. I thought I was about to watch these two super hero cosplayers start fucking. So my plan now was to try and get closer to the action. I knocked on their door and she answered the door. She looked fucking sexy as fuck in her costume. They both invited me in so I could talk to them. I think they were rather embarrassed to be caught in super hero outfits by a policeman in full uniform. It turns out that she got the hump with him when he suggested he calls his best mate to come for a threesome. He had even got another costume ready for him. She was not interested in his friend as he had a small cock. She explained that she is up for a threesome, but only with someone with a big cock. That was my cue to get my big cock out and I suggested that I could be the third participant in their sexual fantasy. They gave me a mask to wear that suited my uniform and we got down to business. She did her very best to fit both of our cocks in her mouth before we took turns on fucking the shit out of her tight wonder pussy.
