It has been a few weeks since Scrappies life had changed. Not long after being turned into a female and raped by Matches. She finds out she was pregnant with dragon eggs.  After 2 weeks of being gravid she finally lays her eggs. Matches watches with arousal as his spawn are laid. After watching Scrappy lay her eggs Matches decides he wants more female pups to breed. Knowing he can only make eggs Matches decides to have a mammal breed her full of pups. And he knew just the male.

He drags Scrappy to Scooby's classroom telling him that Scrappy was a new student that was skipping class and should be part of a demonstration. "Uncle Scooby it's me Scrappy!" She shouts at her uncle. Unfortunate for her, Scooby does not recognize his former nephew turned niece. "What a cute werepup you are, here for a hands-on lesson?" he asks the struggling pup. Suddenly his nose twitches as he picks up her fertile scent. "Oh, you are definitely ready." He says with a slight growl as her scent triggers his instincts to breed.

Scooby picks up scrappy and holds her down on his desk. "Class it's time for another demonstration on sex" he says as he looks at his class of monster girls. all sporting baby bumps. Scrappies eyes widen when she sees Scooby's member. "Wait! Uncle Scooby it's too bi-" she was cut off by the beast of a cock penetrating her tight folds.  "Damn you're the tightest one so far." Scooby says as he can barely move with her vice like grip. After waiting for her to adjust he quickly starts fucking her roughly. The normally gentle lover is driven by his instincts demanding he breed the fertile pup with his pups.

Scrappy while struggling weekly in her uncle's grip, was slowly succumbing to her role as a broodmare. She curses her body for enjoying the rape as her juices ease Scooby's entry.  With the extra lubrication Scooby was able to speed up and reach her loosened cervix. Scooby lets out a frustrated growl that she's too small to knot.
Scrappy lets out a yip as Scooby pulls out and sits in his chair. He then plunges her back onto his cock. This new position allowed him to pierce her weakened cervix. This was the breaking point for Scrappy. She came as she embraces her new role as a breeder. "Please," she begged. "Give me your pups" She pleaded. This sets Scooby off as with a primal howl, he floods Scrappie's small womb with strong virile cum. Scrappy lets out a pleased sigh as she basks in the warmth of her bulging womb.
Deep inside her womb, several young eggs were bathed in Scooby's energetic sperm. All eager to knock up the young pup. The vulnerable defenseless eggs stood no chance as the powerful swimmers easily broke through their soft shells, Egg after egg was claimed by Scooby. Soon 8 fertilized eggs will grow into 8 pups within Scrappie's womb. Scooby pulls out of the exhausted pup and gently lays her on his chair. Matches looks happily at the sleeping scrappy knowing he will have more pets to breed.
