oven sex is when one cranks up the heat on the oven and shoves a douche up their ass and leaves then sits on the oven for hours and melts the douche after. A while after that they go to the family doctor and gets him to pull out a weeks load of shit and it goes all in his mouth
Frank: honey, are you alright do we need to see billy (family doctor)
Malinda: yes sweetie, I did a oven sex before
