Cal parks his car on the street in front of Mark’s house. As he walks up the driveway towards the back of the house, he catches a familiar scent. Somehow he recognizes the scent as Mark’s Mom’s K-9 partner, and what’s worse, she’s obviously in heat. Cal stops at the chain link fence that surrounds the backyard. There she is, tied up in the backyard next to her doghouse. Cal’s instincts start to take over and the red pointed tip of his new doggie cock begins to slide back out of his furry sheath. “Maybe coming here wasn’t such a good idea,” he says to himself as a wet spot begins to form on the front of his shirt over his drooling member.
“Why’s that?” a voice from behind snaps Cal back to his senses. Cal turns to see Mark walking up the driveway.
“Uh, I was just thinking that hiding out here might not be such a good idea. I don’t want to impose,” Cal replies.
“Dude, it’s not a problem,” Mark replied. “I love hanging out with you. You’re welcome here anytime. What’d you spill on your shirt?” Mark asks, pointing to the large wet spot over Cal’s throbbing cock.
“Uh, that’s the reason I need a place to hide for a while.” Cal sheepishly replies. “Promise you won’t freak out.”
Mark has a confused look on his face but nods in agreement. He then watches as Cal slowly raises his shirt revealing a huge canine cock sticking out above the waist of his shorts.
“Cal, is that for real!?” Mark exclaims.
“Yep. It’s attached and 100% me. I couldn’t help but get boned up when I saw your Mom’s dog. You know she’s in heat, right? This thing just seems to have a mind of it’s own. Makes it hard for me to resist doing stuff. That’s why I wanted to lay low for a while.”
Mark’s expression is a mix of curiosity and amazement. “Can I touch it?” he asks.
“Uh, Sure. I guess.” Cal replies.
Mark reaches out and grasps the fur-covered sheath, pulling it down a little further to reveal even more of Cal’s stiff red dick. “This is so cool,” he whispers under his breath.
Cal leans back against the fence and lets out a soft moan as Mark begins to massage the crimson tip. Cal always wondered if Mark was gay, the way he worshiped all the jocks in school. This seems to confirm that suspicion. Between the scent of the bitch in heat and Mark’s massage, Cal begins to lose himself in the moment. Reach out, he places his hand on the back of Mark’s head and pushes him down towards the dripping tool.
Mark is totally captivated by his friend’s doggie dick. He’d messed around with a few guys from the football team in high school, but this was totally different. He reaches out with his tongue and begins to slowly lap the precum off Cal’s cock.
“Oh yeah!” Cal growls, “I’m going to make you my bitch.”
Mark slides the length of the cock all the way back into his throat. The pointed head seems to make it easier to take. Cal leans forward, grabs Marks head with both hands and begins to quickly pump his tool deep into Mark’s mouth.
“That feels so good.” Cal moans. He’s so caught up in the moment that doesn’t notice the changes to his own body. The soft fur that covered his crotch has spread over most of his body and his hind legs have begun to reshape. His ears are growing out and his nose and mouth begin to stretch into a muzzle
Mark lowers himself further to the ground to continue nursing on Cal’s dick. Without letting the cock slide from his lips, he lowers himself first to his side, and then rolling slightly until he is completely on his back, neck pushed up to meet Cal’s thrusts. Mark can smell the musky scent of Cal’s balls as they jiggle in front of his nose. Suddenly he feels something push against his lips. It’s Cal’s knot. Forcing his mouth to open as wide as he can, Mark let’s Cal push the knot in. “Oh man,” Mark thinks, “this is like trying to swallow a tennis ball!”
With a free hand, Mark manages to unbutton his shorts and pull out his own rock hard cock. He’s so turned on having Cal’s cock filling his throat, his dick feels like it could go off any minute all on it’s own. Suddenly Mark feels a long wet tongue begin to lap at his cock and balls.
Cal’s hind legs begin to quiver a bit as he begins to pump his huge load deep into Mark’s gut. This sends Mark right over the edge and he sprays his chest and belly with his own sweet spunk.
Mark can’t seem to get his mouth off Cal’s cock and realizes that he may have to let the knot go down a bit if he doesn’t want to hurt Cal with his teeth. He opens his eyes to see Cal’s tail wagging happily back and forth.
“Holy crap!” Mark thinks, “What have we done?”
