***THIS WILL COME IN HANDY...
before she comes over look at the most disgusting, nasty, crude, sick, unhuman thing u can find on the internet or something. then while ur takin care of business if u feel like ur about to blow ur load just imagine that nasty shit from before, i no its weird but it seriusly helps, i can last for hours like that...just as im about to blow i think of it and the hard is still one just the cum has calmed down and i can go real hard again.
