The Birthday Cake 

Having sex with a girl from behind, and finishing on her ass. After you've finished you use a rubber spatula to evenly distribute the cum on her butt cheeks, as if it were icing on a cake. When this is complete you may stick a candle in her butt hole and light it. Finish off by putting on a birthday party hat and you have successfully completed The Birthday Cake.

"Dude, I gave Steph the birthday cake last night!"

"Oh that's nice of you dude, was it red velvet or...?"

"No dude, I came on her butt and smeared it with a spatula."

When you make a cake and rub the left over frosting on your girl's tits, then titty fuck her. Then she sucks the frosting off your dick like she is blowing out the candle.

On my birthday, after my party. My girl took me to the bedroom and we did the birthday cake.

The Happy Birthday Cake 

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!

Tonight I'm going to give my girlfriend The Happy Birthday Cake!
