Tolerance is a bitch. It ain't like when you were 15 and the sight of a nipple through a t-shirt could get you off. Watch a little porn, and the fact that the girl is sucking cock on camera just isn't such a big deal anymore. So you move on to Gag Factor. And then, after a while, it too is no big deal. Hell, the chick is barely even puking.

Snuff films can bring the rush back, but it, too, is temporary. "Hell, the begging for her life bit was soooo derivative. I've seen better. And she didn't even see the final death blow coming, that totally killed my wood.

"Dude, I've got some new shit for you. Snuff Bukakke. This will get you back!"
