"That should do it," Joan said at last. "Now you're ready for that beast's fat prick. Have fun, child."

"I will, Mom."

Jill arched her back and spread her thighs wide. Then she looked back over her shoulder and called to the dog. Immediately the animal mounted her and wrapped his forelegs around her slim waist. She shivered hard when his belly hairs brushed against her soft ass, but she wasn't at all frightened.

"Oh, good doggie," said Jill, licking her lips dreamily. "Fuck me, boy. Stick that big prick in me and pop my cherry."

She wriggled her ass, hoping to excite him even more.

Shep held her waist tightly and began humping. His hips lunged forward again and again as he drove his cock against her cunt lips with brutal strokes. He jolted her hard with his cock, all the time threatening to pierce her fuck-hole.

"Eeeeee!" squealed Jill as shivers raced up and down her spine. "Ooooooh! That big fucker is something else."

Shep continued to hammer her cunt lips with his fat prick head, until her cunt hairs were soaked with his jizz. Finally, his cock head slipped into her cunt crack where it belonged and forced apart her smooth young cunt lips.

"Aagh!" she cried, throwing back her head. "Shiiyyiit!" Excitedly, she began pumping her cunt muscles prematurely.

Shep, feeling the heat of the girl's tight pussy, humped harder and drove his prick up into her fuck-hole. His cock banged her cherry mercilessly, and she screamed in agony. But then he fucked into her again and ripped through her cherry.

"Iiieee!" she screamed, shaking her head miserably. "Oh, fuuuck! There it goes, Mommie!"
