Chris begins to sweat and pant as he tries to concentrate on the homework, the tent in his pants tight.
Brandon pulled at his collar trying to cool himself off, "Yeah, it does feel a little warm in here." He said sniffing at the air, his nose rising.
Brandon's dick flexed slightly as the scent was recognized suddenly blurting out, "Are you hard?! Uhh I mean are you ready?"
Chris slowly turned back around on the chair, his heart beating like crazy, doing nothing to cover his obvious bulge, panting as he noticed a growing outline in Brandon's sweat pants. "How did you know?"
Brandon sniff at the air again, lust starting to overcome his rational thought once again. "I can smell it," he said licking his lips.
"Maybe I should go," Chris said jumping up, his pants falling slightly, stopped by his hard on, pubes showing below his now thin and muscled stomach.
Quickly moving toward the door Chris felt a hand on his shoulder, looking at it he saw dark pointed nails on hairy fingers and hands.
"You know you want to stay." Brandon said his other hand wrapping around and squeezing Chris' crotch.
Chris moaned in pleasure as Brandon licked his neck, nibbling his ear with his sharp teeth.
Brandon moved around to Chris' front; pulling his shirt off of him, running his hand through the new blond hairs in the middle of Chris' chest.
"What are you?" Chris said as he saw Brandon's face now getting hairy, the nose turning black.
Brandon growled back, "Man's best friend," as he pulled his own shirt off.
Chris couldn't help but moan at the sight of Brandon's strong hairy pecs and thin chiseled abs. Chris couldn't hold back any longer, fingers pushing into Brandon's sweats, pulling them down in one swift motion. He dropped to his knees, drooling as the uncut member in front of him slowly grew, hairs starting to grow along the length of his foreskin, a glistening pink tip beginning to poke out the end. He reached a hand around the thick member, pulling the hairy sheath skin back, revealing more and more of Brandon's changing cock. Chris' eyes glazed over as he pushed his tongue out, licking the sweet moisture from the tip.
Brandon growled in pleasure as Chris pushed his mouth over the whole length, his face beginning to protrude as his ears pointed. He began to hunch over as his shoulders pulled in slightly, his body starting to hump Chris' mouth as Brandon slumped over his head.
Chris reached his hands around, feeling the thick hairs on Brandon's ass, the cheeks spreading as he slumped further over. Chris could feel a bulge over Brandon's ass, caressing it as he would a cock as a hairy tail began to push out.
Brandon's legs altered as he bent over the rest of the way, his pawlike hands touching the ground on both sides of Chris between his legs, his muzzle drooling and dripping down Chris' back as he madly began to hump his face like a dog should.
Chris felt Brandon's knot thicken, unable to take the full length of his cock in anymore, his body suddenly stopped humping stream after stream of warm cum shooting into Chris' mouth.
Chris fell back to catch his breath, wiping the cum from the side of his mouth as he looked at the Dog beast Brandon come down from his orgasmic high. His hand moved down to scratch an itch on his tight abs, looking down, watching as the blond hairs quickly began to spread.
