Portablumpkin 

Getting a blowjob while shitting in a porta potty

I was at this tractor pull in Tomah and got my woman to give me a portablumpkin.

After receiving fellatio while dumping in a portapotty, cum in the girls eyes temporarily blinding her. Then, exit the portapotty and simply push it down a hill tumbling end over end.

i.e. Location, location, location

i got bored with getting blumpkins so I upgraded to the tumbling portablumpkin.

Porta Blumpkin 

The act of getting a blow job while taking a shit on the toilet inside a Porta-Potty. Very similar to the plain BLUMPKIN. Just watch out for the blue water.

Why don't you come inside this porta potty and give me a Porta Blumpkin.
