I recall when I was like 16 I went bowling with some friends and we all get really fucked up drunk. Drunken bowling = depressingly poor.
So myself and my girl decide to go for a quick one in the disabled toilets as I had previously spotted them as a prime dogging spot.
So I'm lying on this filthy piss ridden toilet floor as she writhing on top of my half erect/half whiskey-dick and shes facing the wall, I'm facing looking over her shoulder at the door. Some father and his kid open the door (which we had drunkenly forgot to lock suffieciently) and is like WHOA! Well...actually he was completely dumbfounded and silent. He closes the door and probably cant fathom the words he is going to tell his son. I keep going as I am getting that drunken false alarm that your just about to come (in other words you can kind of feel your dick again for a split second) and she hasnt even realised what had happened anyway, I tell her to "get off me a second, I gotta check if the door is locked", so slyly I go and lock the door PROPERLY this time, I get her on top of me again, this time on top of the toilet seat, we're fucking for like 10 mins, and I hear this awful cracking noise beneath me, I stand up and low and behold the toilet seat had broken.... Fair enough, Why should I care? Next up, security starts banging at the door, we look at one another in panic. Quickly, quickly, quickly get dressed, fuuuuck.
Sweet, Im dressed, now what the fuck did I do with that condom? I try to think but in the confusion of the angry shouts on the other end of the door, I prepare instead to face the music/overgrown fists of a security guard. I open the door and get all sorts of outraged babble as the man from before stands with his hands by his hips. Naturally at 16 years of age, my first thought is to be like "What!? That's bullshit, we weren't having sex". Poor move son. The security man points out that my trousers are on inside out to and points towards one of my etnies where a bloodied remainder of what I assumed was a condom lay hanging over the edge of my shoe. Needless to say we were quickly removed from the premises where I then had to listen to my girlfriend bitch at me for not telling her someone had walked in.
My only defense was "You didnt tell me you were on your period"
Good times.
Another bad one was with the same girl actually, I used to stay in my grannies house when me parents would go on holidays and shit.
So I would have her house free every friday night when she went to Bingo. So Im again fucking this girl when I think I hear the front door close, I wait a second, and no noises are heard...just keep going. Seconds later my granny opens the door to see her grandsons ass pumping into his underage girlfriend ON HER DINING TABLE may I add. She leaves without a word and we pull up those trousers faster than they came down. I run out and apologise profusely, she laughs it off when my girlfriend leaves, tail between her legs.
Gotta keep in mind though my granny is pretty awesome, she used to grow weed for me.
