Danger Shag 

Danger shag.....Basically you get a bird in bed (prefrably of the african/african american sort) and you go to her house and proceed with natures intention of pile driving making as MUCH noise as possible while the father's downstairs.....when you're close to the end of your stamina bar you shout said fathers name and have to finish and tidy yourself and the surroundings up before the behemoth makes it upstairs and (pardon my french) fucks you up from the inside out

I had a Danger shag the other day but i got caught and her dad snapped my dick off
