The act of smearing cream cheese around the ring of your girls asshole, fucking her in the ass, pulling out and blowing your load on her face, then as she precedes to suck your cock, you have a delicious cream cheese and cum mixture all over your dick and her face. This one will surely make her happy.

Bob: "Jimmy you sick fuck, doesn't that involve her sucking on your cum, cream cheese, and shit covered dick?"
Jimmy: "Why yes it does! It sure is delightful!"
