As Karen walked into the door, she was shocked at what she saw. Her son and naked daughter on the couch.
"Kids, what's going on here." asks Karen
Cal sits up, "Have a seat Mom" he asks.
Karen closes the door, and sits down in her husband's recliner.
Katy says, "We found a way to be dog people." Cal raised the collar and then reached his hand into the lycra shorts, to pull out the canine dildo. Katy continues, "Cal now has female dog parts, Mark is his canine mate, and Dad is your bedroom as a hermaphrodite human/great dane hybrid."
Karen stares at her kids in disbelief, "Where's your dad?"
Cal says, "In your bedroom"
Karen quickly gets out of the chair and storms off to the master bedroom, and pushes the door open to find Mark's cock stuck in her husband's canine vagina.
"JIM!" screams Karen
Katy quickly puts the collar around his mom's neck, and then asks, "Mom, please sit down on the bed."
Cal looks to his sister, "You know her mind is filling with those canine urges, we better not keep her waiting long."
Katy goes over to Mark and Jim, "You two can show my mom what it's like to be canine." Both Jim and Mark grinned ear to ear. Cal took the dildo over to Mark, "Here. Try to whisper suggestions to my Mom before removing the collar. It's how I got mine. Me and Katy are going to the mall."
Jim growls softly, "Kids, there's some money in my wallet, come back late."
Katy and Jim head to Katy's room for clothes to change into. Katy hands Jim a spandex shirt and a pair of keds shoes. Katy puts on a similar shirt, and a pair of spandex tights. "We are going to the club first. Are you in?"
"I already have an appetite for canine cock, I can settle for human while Mark's busy." smiles Cal.
They leave together in Cal's car to a local club popular with the twenty something crowd.
