Goo runs away.

After about half an hour you feel the knot shrink and Buster pull out of you. Before you can make any response he runs off outside. The goo ashamed that he lost control over his own body. You don't bother to call, you're to confused to try. You crawl to an armchair, doggy cum pouring out of your ass. You pant still confused about what happened. You decide to pretend that it never happened. After a shower, a clean of the living room and an ice-pack for your ass you decide to start your day proper... Or maybe find Buster.
