When a man loves his woman so much, he is willing to compromise on that day of the month. First, the dong is used to ravage her booty hole, and upon pulling out, the man's bell-end(penis head) is covered in a peanut butter substance. He then proceeds to mash his wanker into the jelly-filled period cooter, thus creating a perfect mashup of peanut butter and jelly in between two slices of ass.
My side piece has been on her period for the past week, but it's okay since I was able to make a delicious PB&J between her enormous bum cheeks.
