Vet Clinic, Part 3

by GoodLittleKaren

Karen slowly worked her finger in and out of Shelby's bottom. She could feel the girl's body react as her finger tenderly carressed the inner walls.

"You're doing beautifully, sweetheart! Does it feel nice?", she asked.

"uh huh!", Shelby responded softly.

Karen's fingers rubbed Shelby's moist folds as she coached the girl. "Just move back and forth honey. That's right." Shelby pressed back on Karen's hand. "I think you're ready dear!", Karen whispered softly. She slipped her finger from it's place, deep within Shelby's rectum. She watched the girl's anus return to it's normal, closed state.

"Now. it's going to feel a little scary at first Shelby. But if you relax and don't fight it...it will feel much nicer. Are you ready?"

Shelby nodded and murmured, "Uh huh. I...I think so!"

The Lab needed very little encouragement. Karen's hand took his furry glove and tightened her fingers, aiming it to Shelby's butthole. The dog's hips shifted forward. Shelby let out a groan as she felt the dog's penis begin to invade her.

"Uhhhh. Ohhhhhhhhhh."

The Lab plunged forward, his forepaws steadying himself on the girl's sides. He gripped her tightly and began humping.

Shelby tilted her hips and completely accomidated his entire cock. Her eyes widened in awe as she felt herself filling.

"Uhhggg. Ooooo. Ohhhhhhh. Ahhhhhhhhh.", she grunted loudly. Karen slipped her hand beneath and teased Shelby's dampness. The dog's body slapped faster and faster against the intern's bottom. Karen could see Shelby's legs shaking as she allowed herself to be taken. Without a word, Karen's fingers sought the hidden bud of Shelby's clitoris. They pinched and beckonned the swelling nubbin. being completely inside the girl's ass, the Lab's knot began to grow. Locking himself within the girl. Shelby could feel herself being tugged by the knot. The tantalizing of Karen's fingers made it impossible to hold back.

Karen watched as Shelby gasped for breath and pushed herself back against the dog's cock and Karen's fingers.

Her throat emitting gutteral groans. "Ughhhh....Awwwhhhhkk...Uhhhhhhhhhh!!!!" Karen felt Shelby's release. Burst after warm gush began to squirt. Karen's hand became soaked and her fingers had trouble holding the throbbing button of Shelby's clitty. Slipping off it and returning. Karen revelled at the sight of the intern's body responding this way. The girl's orgasm was fierce and furious. The dog had collapsed on Shelby's back and Karen knew he was squirting his doggy cum deep into Shelby's warm bowels. Shelby's firm, perky breasts jiggled as her body writhed. Her young legs barely able to support herself.

The moment was glorious. Karen pressed her own legs tightly closed. Without even touching herself, she felt her own orgasm. Her fingers could feel the last gush of Shelby's cream...signalling the end of her cummy. She carressed the girl's back, instructing her to remain still for several more moments. Karen knew that if the dog's knot did not subside it would be extremely painful for Shelby. It only took several more moments for the dog's cock to deminish. Shelby gasped softly as she felt the dog slipping from within her. Now, free from the intruder, Shelby let her legs go and slid down...laying on her side as the Lab moved away. Her eyes were filled with tears, yet she could see the dog's red cock, coated with silky wetness. She watched as Karen eased the dog to a lie. Karen gazed down at the glistening, veiny red doggy cock. Shelby watched in silence as Karen's mouth slipped carefully onto it.

Karen could taste the musky flavor of Shelby's buttcream as her mouth devoured and cleaned the precious doggy cock. Karen's tongue swirled...her head bobbed as she lavished the fading doggy cock. Karen moved to Shelby and kissed her pouty lips, easing her tongue into the intern's mouth. Shelby allowed her own tongue to find Karen's as she accepted the kiss. Shelby could taste the blends of flavors.

Karen knew she had found the perfect little partner now. There were no longer any barriers to provent them from indulging. It would be a relationship that lasted nearly four years. In those years, Karen and Shelby would share many, many wonderful things.

The end...for now. Please enjoy this latest saga.
