Ghoul in the Basement - Let the mutt finish.
From Create Your Own Story
You decide to wait, and settle down in the bushes to watch.
This dog has some stamina. It goes on and on like a jackhammer, slapping its cock in the girl's tiny cunt for almost an hour. Its claws leave small scratches on her shoulder and back, and every now and then it nips her on the back of the neck. An animal thing to show it's in control.
Finally, her cries increase as it starts to speed up. Exhausted, her arms give out and her face falls into the dirt but it just ignores her, thrusting harder and faster until finally, with a howl, it comes inside her.
It takes a few moments to calm down, panting and slobbering all over her back as it waits for its knot to subside. Finally, it pulls free and lopes off into the undergrowth.
