The Neti Hot Pot Dick Snot Surprise uses the Neti Hot Pot at the conclusion of a blow job while standing upright. While getting your nob slobbed, have a Neti Hot Pot handy. Right before you blow your load, tilt your head to the side and use Neti Hot Pot. The hot diarrhea will enter your top nostril and travel through nasal cavity and exit out of your bottom nostril, then falling down and covering the giver of the blow job with a nice coating of snotty diarrhea. While they are being covered they are also receiving a hot load of cum in their mouth.

I was feeling stuffed up and horny, so I called up Sarah to suck me off. Little did she know i was going to give her the ol' Neti Hot Pot Dick Snot Surprise.
