Greesy Kayak 

While a male is recieving oral sex from an angry female to get her back he stick his thumb in her rectum and while shes giving him the 'oh shit theres a thumb in my butthole face' he squirts his hot juicy load into her nasal cavity thus rendering her useless.

My girlfriend was pissing me off so to make up for it she sucked me off so i gave her the greesy kayak.
