[I Love Mr Slope]

I guess I masturbate 6-8 times per day during the week and maybe up to 10 or 12 times per day at the weekend.

For the whole of September I'm going to carry about an old school film canister in my pocket (the kind that used to come with the films in the 'roll of film' avatar), and every time I masturbate I'm going to cum in it. I'll have to take it to work etc so will have to find a way to make sure it doesn't leak.

I reckon I can fill it up within 30 days but my sister says it's going to dry out and won't fill up within a month no matter how much I masturbate. We've got $100 riding on it so who's going to win?
