13 Inch Grinch 

It was a cold Christmas night and I went out to wee. so I took out my wiener and let is wee. but then I felt a tender grip. I screamed and shouted as the grinch sucked my dick. he fucked me hard as hard as he could with his long long tender wood. I will always regret that midnight wizz but no one will here me shout for my mouth is filled with jizz. This is the legend of the 13 Inch Grinch.

Man, you look like the 13 Inch Grinch met with you last night!
