After making love, a man ejaculates on his partner's anus. After ejaculation is complete, the partner expels gas through their semen covered anus. This causes a "spouting" phenomena similar to that of a whale during its normal course of breathing through its blow hole.
Man: I just blew my load on your ass. Get ready to fart!
Partner: Get the camera ready. Here it comes!
Man: I can't wait to post these pics. What a perfect Baby Beluga!
Partner: Get the camera ready. Here it comes!

That baby beluga is a whalefuck, you can see her camel toe, her pannnis hangs over her belt, and you can count her pussy lips when she bends over provided that her legs are apart
