McDonalds Sundae
The sexual action that involves cumming in a girls ass. There are three ways of doing about this. The strawberry sundae is having your girl menstruate in your ass. The hot fudge sundae is have you shit in her ass crack and the caramel sundae is made with you pissing in her ass.
We ordered a McDonalds sundae last night. Oh shit, she was pissed.
