His wife takes charge.

Sarah woke up to the sound of a scream from the guest room. "John!" she whispered and ran out the door, not bothering to put anything over her thin nightie. Her man was in trouble. She threw open the door to the spare bedroom.

Her jaw dropped; some sort of monster was there, up to its hips in a young coed. The thing was fucking her hard and fast while she whimpered and pleaded and moaned. But most importantly, there was no sign of John. The only sign he had ever been there was that horrible cock ring, split open and lying on the bed.

The girl let out a long slow moan, followed shortly by a gasp and groan as the monster stiffened its back, obviously shooting a wad of yuck into the girl. The creature pulled a good foot of furry cock out of the coed and turned its hungry eyes on Sarah.

Sarah gulped, suddenly realizing the danger she was in. The beast was some sort of wolf-man: some sort of extremely horny-looking wolf-man.

"Calm down, boy." She had no reason to believe the wolf would react, but she was terrified enough to try anything.

The wolf-man's eyes cleared and its tongue lolled out the side of its snout. Its tail was wagging. It bounded toward her like a dog when its master arrived home, then grabbed her shoulders and started licking her face.

"Down boy! God, you're just as bad as..." her eyes widened as she put two and two together, "...John!"

The monster switched to licking her neck and started rubbing his enlarged member against Sarah's leg. If a real dog had done that she would have been repulsed, but somehow knowing it was John was getting her aroused. And other, stranger ideas were forming in her head...

She pointed at the cowering girl, "What's your name?"

"B-Becky."

"Well Becky, you snuck into the wrong house tonight. This is either the luckiest night of your life or the unluckiest." Sarah pushed John aside gently and knelt down. "Becky, crawl over here on your hands and knees."

"Why would I...?"

Sarah scratched John's head between his wolf ears. "I could sic him on you."

Becky rose to her hands and knees despite the soreness between her legs. She crawled over to the woman.

Sarah smiled evilly, "You had the doggy, now you get the pussy. Lick me." She hiked up her nightie to present her mound to the coed burglar.
