"Wow, Marcie, that's heavy!" Kathy gasped, seeing her cousin freak out completely. "Come on, Pardner, fuck her! Go on, boy, go on and mount her. She wants to have your cock in her cunt."

The words made Marcie pant even more. Something had taken her over, something that was pushing her even further than her forward cousin Kathy had gone. She raised her legs a little more, letting them fall to either side of her body while she rolled her ass from left to right. At first the dog wasn't sure what was going on. He whimpered, staring at her, then tilting his head to one side and eyeing the frantic brunette. He dropped down, licking the dark wet pink gash of her cunt again and again. Marcie babbled and gasped to him as he raped her with his tongue. She brought her feet together at the sides of his head, rubbing them against him. How that tickling touch sent another rush of sensations through her! She couldn't think. No, she simply couldn't muster the strength to have one continuous line of thought in her mind. All she could think now was fucking, fucking, having that dog fuck her!

"Fuck…!"

"Oh yeah, Marcie, he's gonna do it! Doggie's gonna do it," Kathy said, her eyes wild and glazed.

Rolling over, the brunette pulled Pardner back, then began shoving him forward. The dog whined at the touch, then finally seemed to guess what was needed.

Marcie was working her ass around in tight, frantic circles, crying through her nose with excited little wheezing cries. It was crazy. It was just crazy to be doing something like this.

"Go on, boy, go on and fuck the bitch!" Kathy cried.

Kathy was panting heavily, rubbing her cunt with one hand while guiding the big dog with the other. Pardner snapped back at the girl, then stood up, wagging his bushy tail slowly from one side to the other.

Marcie looked up heavy-lidded, peering through her long blonde lashes at the beast in front of her.
