Vet Clinic, Part 2

by GoodLittleKaren

Karen clung tightly to the Mastiff's hips. Within her butt she could feel the doggy's knot tugging for release. As usual, she was totally lost in the moment. She has no idea the back door of the clinic had allowed the newest intern Shelby in. Karen did not hear the office door close. Tang's wonderful cock had deminished to a point of being able to slip free. It left her with a slight "plopping" sound. Karen quickly tried to clamp her anus closed. But not before some of the dog cum seeped out and dribbled down her wet crease...blending with her own cum fluid.

Shelby stood on the other side of the office door. She had only meant to retrieve her things and leave. Her mind took in the event she just witnessed. Karen on her hands and knees accepting the loving pummle of Tang's penis. Hearing Karen telling the dog what a "good boy" he was and how much he was making "mommy" very happy. Shelby slipped away quietly.

The next morning, Saturday, Shelby went back down to the clinic. Karen was surprised to see her.

Karen smiled and told her it was Saturday and that she didn't need to come in that day.

"I just thought I would...uh...see if there was anything...anything I could do around here today.", she told Karen shyly.

"Well. Actually I was going to shave Tang today to prepare him for neutering, Karen said. "But I suppose I could use a hand." Karen could not tell Shelby was avoiding her eyes. The two of them went back into the kennel.

"Oh! There's mommy's good boy!", Karen said to Tang. Her words sent Shelby's mind back to the previous afternoon's event. Her mind's eye could clearly see Karen underneath Tang's strong body. Karen noticed her blank look.

"Is anything wrong honey?"

Shelby snapped back to the moment. "Huh? Oh. Nothing. I...I was just thinking. That's all."

She helped Karen lift Tang up onto a metal table. She pet his furry body while Karen prepared the clippers. Karen had her hold Tang's legs apart. She glanced down at the thick sheath and large testicles. Karen's voice once more brought her from her thoughts.

"He's quite handsome, isn't he Shelby?" Shelby almost jumped.

"Uh. Uh yeah. I guess so." she replied.

Karen saw the young intern's eyes gazing at the dog's penis. Karen's own mind drifted for a moment. Imagining her young intern sucking Tang. Shelby's voice brought her back to the moment.

"Their different from...uh...guys, huh Karen?"

"Yes. Yes they are honey." Karen said softly in reply. Karen looked at Shelby's green eyes, and saw tears beginning to well.

"Honey. Something's wrong. What is it? Please. Whatever is bothering you, you can tell me!" Karen placed her hand over Shelby's, squeezing it gently. Shelby nearly burst into tears.

"I'm. I'm soo sorry Karen., she sobbed. "Yesterday I came back to get my things I forgot and...and...", she hesitated. Karen knew instantly what Shelby was trying to say. She tightend her hand on Shelby's.

"And you saw me? Didn't you Shelby? You saw me...with Tang. In the office?" Tears streamed from Shelby's eyes. She nodded silently. Karen lifted Shelby's chin and looked deep into her eyes.

"It's okay honey. You didn't do anything wrong. Honest! I should have check the door lock." Karen's hand soothed away the tears. She could sense Shelby's curiousity and knew she had many questions. Karen tried to answer each one. "How did it happen?" "Has she aways done that?" But the final question..."Does it hurt?" is what really caught Karen's attention.

Karen leaned in and kissed Shelby's lips softly. "It only hurts if you are not properly prepared honey!"

Shelby admitted that she had never thought of doing such things before. Karen took her hand and placed it to Tang's cock, guiding the intern's hand along it's thickness. Tang whimpered a little.

Karen knew that this would be Shelby's first anal. She also knew Tang was much to large for her. She told Shelby this and they lifted Tang off the table and returned him to his kennel. While Shelby fastened the cage door, Karen took a lead and let the Labrador out. The Lab was a meduim sized dog. Also about a year old and weighed about 50 lbs. They both took him to the office.

Karen kissed Shelby once again. "Are you sure you want to do this honey??"

Shelby nodded. Karen went to place the blanket after telling Shelby to undress. The girl's supple body slowly came into view. The firmly formed breasts. The soft patch of downy pubic hair. The perfectly shaped backside. Karen removed her own clothes and had Shelby kneel on the blanket. As Shelby went down on all fours, Karen's hand carressed the glorious orbs of the teen's bottom. Shelby's body tingled as Karen told her of "preparation and relaxing". Karen parted the girl's cheeks...gazing at the tender prize within. A pink, tiny wrinkle. Perfectly shaped. Karen licked a finger and gently massaged the soft bud. Shelby's body responded as Karen urged her finger gently into it. Karen's encouraging words coached the girl how to relax and squeeze. The warm glove of Shelby's rectum hugged Karen's finger as it glided slowly in and out.
