Dude last night I was so stoked. I was just dumping, drinking my folgers pumpkin spice coffee, and then this hot girl randomly came in and gave me a blowjob. It was amazing. Gotta love blumpkin spice.

Blumpkin Pie is a delicious home made recipe that any male with or without cooking skills can make.
While receiving fellatio you shit in a pie tin. Then as you are cumming, you put the cum ontop of the poo poo. Then you shove the girl's face into the pie and force feed her the rest of the meal. This is ganranteed to be a meal she wil never forget and will talk about it for years to come.

Carina: What the fuck is your problem?
Brian: What are you talking about?
Carina: The blumpkin pie you made me eat last night... there must have been a tainted substance in it because i feel nauseous and i think i'm going to blow chunks!
Brian: oh, well just don't get any on my shoes, they are new.

Male is taking an upper decker and the female is sitting reversed on the regular toilet seat taking a shit and giving the guy head.
We really fucked up the toilet at Kieth's house when Sharliene and I did a double blumpkin, Shaeliene is such a dirty girl.
