YumYum in my TumTum 

A story about a gay couple guzzling each other's sperm.

As Andy stiffened up, he shot a large load into Brian's anus. Feeling strangely drawn to it, he then proceeded to lick it up out of Brian's asshole and began snowballing it between him and his mate. After swallowing, they both exclaimed, "YumYum in my TumTum!"
