Mark can feel Cal’s knot slowly start to shrink and he pulls his mouth off of it. Cal is still lapping up Mark’s cum with his long German Shepard tongue.
“Cal, you’ve totally changed!” Mark exclaims.
Realizing that being seen in the driveway having sex with a German Shepard is probably a bad idea, Mark grabs their cloths and runs for the door. “Come on Cal. Come on boy!”
Somewhere in the back of Cal’s mind, he realizes that he’s not really suppose to be a dog, but he can feel his new canine instincts slowly taking over.
Down in the basement, Mark tries to come up with a plan while Cal curls up in the corner and begins to lick himself. “Alright, I need to come up with a good excuse for why you’re here. Having a friend over for the night would have been easy enough to explain, but bringing home a strange dog’s another story. Cal, can you understand what I’m saying?”
Cal looks up at Mark with his big brown eyes and wags his tail… then goes immediately back to licking himself.
“Obviously you have your own priorities now… I wonder how long it will be until you change back?” Mark mutters to himself.
Just then the phone rings.
“Hello?” Mark asks.
“Hi Mark,” his Mom answers. “I’m going to be late tonight. There was a robbery and I’ve got tons of paperwork.”
“Are you okay Mom?”
“Oh, I’m fine. I just won’t be home to make you dinner. Don’t wait up, okay?”
“No problem. I find something to eat. Don’t worry about me.”
“Okay, I won’t. Take care.”
“Bye Mom.”
Slightly relieved, Mark looks over at his canine friend. “Well, that just bought us plenty of time to figure out a plan.” Sitting down next to Cal, Mark begins to slowly pet the top of Cal’s head. “You know Cal, there’s something I’ve wanted to try, but it always sort of freaked me out. But since you’re not really a dog, I guess it would be okay. Besides, I don’t know how long before this wears off and you change back… I may never get a chance like this again.”
Mark slowly moves down to Cal’s bright red doggie dick.
“Let’s just see if we can get you completely hard again,” Mark whisphers.
Cal watches as his friend runs his tongue up and around the pointed tip of Cal’s cock. He can feel the animalistic desire to mate building inside him. Mark licks his fingers and reaching back, slides them up into his own ass to loosen himself for what’s next. Cal gets the hint and walks behind Mark and begins to lick at Mark’s asshole with his long canine tongue.
“Oh yeah buddy. You know what I need.” Mark moans.
Cal doesn’t need any more encouragement than that. With one hop, he’s on Mark’s back and sliding his dick back and forth against Mark’s pucker. Mark reaches back underneath and helps to guide it up inside his hungry hole.
“Oh fuck that feels good!” Mark groans as Cal’s cock slides deep up inside his ass.
Cal begins to hump with reckless abandon as his instincts take over completely and he takes Mark as his bitch. Cal pounds into Mark harder and harder until Mark begins to feel Cal’s knot pushing against his ass. Mark pushes back wanting more until the knot is all the way inside and he can feel Cal begin to coat his bowels with cum.
That proves to be more than Mark can take and suddenly, with out even touching his own cock, Mark begins to spray cum all over the basement floor.
“Oh yeah! Oh fuck yeah! Fuck that ass Cal! Make me your bitch!” Mark shouts.
That’s when Mark notices…
