On your girlfriend or wife's birthday, you buy her favorite birthday cake and feed it to her. About a half hour later, you have sex with her doggie-style, and while penetrating her vagina,you stick a ping-pong paddle, or other flat, round shaped object, into her anus. She then takes a dump that comes out in the shape of a cake. You flip her on her back, placing the "birthday cake" on her stomach, adding a lit candle or two. You then fuck her missionary style, and when you cum you ejaculate "frosting" all over the birthday cake, also extinguishing the lit candles. Happy Birthday, Sweetie!
