You nuzzle your way into the room were the smells of sex are the strongest. You recognize the naked girl on the bed as Katy. Your instincts tell you this somehow all started with her. Your high school crush and hatred of her bitchy behavior merge into a single desire, exposing your crimson tip.
"Buster, do me again, but this time don't stop."
She's mistaken your identity, something she soon won't be capable of, but first you're going to make her beg some more. You leap on her bed and standing over her lick her face. Her body shivers with anticipation as she runs her fingers through the fur covering your head and chest. Katy pounds her loins against the matress making the familiar sound of a kid jumping on a bed. Your exposed cock comes into contact with her bouncing belly and you decide you're waited long enough.
Letting yourself drop you place all your glorious canine weight on katy's nakedness. Her excited screams distract you little over your own heavy panting as your four legs try to straddle her energetic body. Surrounding her throat with your jaw stops her long enough to slide youself in missionary style. Having just been serviced by Buster, you have no trouble thrusting your dripping cock up all the way, locking you in place as Katy suddenly becomes aware of unfamiliar changes in her own body.
