When we went back to tell the others, they had moved into the living room and were watching a movie. Megan and David had paired off again and Adam was sitting with Lyssa. Some campy comedy was playing on the flat screen.

"Hey guys!" Molly got their attention. When they turned to see what she wanted, David hit the "mute" button on the remote. She continued.

"Rob already sent some of the clips from what we did this morning to a friend. He wants us to do some other stuff."

Nodding heads and mumbled "cools" were heard around the room.

"What kind of stuff?" Lyssa wanted to know.

"One guy said he wanted to see us do some bondage, but I don't know what he meant by that. And another one wanted K9. Do you know what he meant?"

David and Adam looked at each other and grinned. Lyssa answered: "I know what bondage is. We did one of those movies last week. It was kinda fun. Daddy and Sissy were like dressed in leather and spanked me, then tied me up, then had sex with me. THAT was the cool part!" They all laughed at that. "But I don't know what K9 is. Daddy," she continued, "what is K9?"

I had sat in my favorite recliner, and pulled the naked Molly onto my lap. She sat across my legs, her right arm around my neck, her legs draped completely over the arm of the chair. I had one hand on her waist, the other toying with a bare thigh.

"Well, K9 is when you have sex with a dog." I let that sink in. All three girls shared looks of disbelief. The boys had not only seen it, but been in a movie where one of the girls had done it.

"Don't that hurt?" Megan wanted to know. "I mean, how does a dog, I mean, oh wow," she was becoming exasperated. "I just don't understand." We all had a good laugh at that.

"Molly, if you look on the shelf under the TV, there's a DVD labeled "Chrissy's Babysitting Adventure. Put that in the player."

She slid off my lap and found the movie. She was obviously very comfortable with her body now, and being nude in front of me or her brother's friend did not bother her one bit. We obviously enjoyed the view as she bent over in front of us to find the movie.

Once she located it and had it in the machine, David hit the "play" button and she returned to my chair to watch with me. I watched the response of the three girls as the movie startd. "Chrissy" was played by a 13 year old girl I had used in movies since she was 11. Both David and Adam had been with her in some of those movies. She was now pregnant and living in another state. We aren't 100% sure, but think it's David's baby. One of my best customers is taking care of her, along with four other girls.

Chrissy is babysitting in the movie. Dressed in a typical schoolgirl outfit, she ensures her charges are asleep, then begins to play with the family's German Shepherd. From her comments, the viewer is led to believe she has played with him several times before. This time, Pepper is wanting more. He nudges her with his nose, licks her to orgasm, and then while she is panting, he begins to hump her leg.

As she turns to look at him, she rolls over onto her hands and knees. Pepper needs no further invitation. He immediately jumps onto her back. She giggles, and flips her pleated skirt out of the way, dropping to her elbows, her ass in the air.

As Pepper finds his mark, she moans in pleasure. He humps her with his own rhythm, and his knot begins to move. Lyssa noticed it first and asked what it was. Adam whispered it was to lock him to his bitch so his sperm could stay in her and get her pregnant. That's in their nature. Did it hurt? She seemed to enjoy it. Neither girl took her eyes off the screen.

Molly was squirming in my lap and I noticed the other girls were squirming on the sofa. The boys weren't unaffected either. Both of them had erections starting. With Molly unable to keep still on my lap, my own cock had started it's journey to erection.

"Well girls, what do you think?" I asked them. My hand had moved up and I was fingering Molly's recently deflowered pussy. She was clamping down on my invading digits and moaning. I used my thumb to massage her magic button, which brought more moans.

"I want to try it. Where can we get a dog? Right now, just watching it made me horny. I need a cock, Rob. NOW!" She turned to face the TV, straddling my legs and sliding her pussy down on my cock. I had no objections.

As she started to grind, I told them I had a dog already. Pepper was mine. He was "on loan" to a friend. I could make a phone call and get him back. All three thought they wanted to try it.

Lyssa and Megan both claimed an erect cock and started riding. We all needed release, and we all got what we needed. Soon, orgasmic sounds of pleasure filled the room as six people reached their climax.

"So, I guess that means we want to do a movie?" Molly laughed, looking over her shoulder at me. She was still impaled (albeit briefly) on my shrinking cock.

"I know, how about a bondage movie where you are forced to do K9?" I suggested. "You could be slaves and we draw numbers or something to determine who goes first."

They all liked that idea and Megan moved off David's cock to find a pen and paper. She would write out a script. The others had to leave for home, but agreed to come back the following weekend I made the arrangements to bring Pepper home.

On Thursday, we went to my friend to pick up Pepper. He was glad to see me, and my friend was sad to see him go. So was her daughter. My girls were excited, and the big shepherd was happy to meet two new potential playmates.

Arriving back home, they wanted to know how he became excited. I told them to just let him sniff and get to know them. Nature would take care of itself. They sat in the floor, Indian style, and let the dog do just that.

As he smelled their scent, his cock started extending. Lyssa was the first to notice, and asked if she could touch it. I told her to be gentle, but he wouldn't mind. In fact, she could do the same with his cock as she could a guy's, and would get the same results. I wasn't surprised when she lay on the floor and started sucking.

Pepper stood and let her bring him to completion, rewarding her with a mouthful of doggy cum. Megan kissed her sister, tasting it second-hand. Both girls moaned and giggled.

"How long does he take to recover, Daddy?" Megan asked. I told her he was pretty quick, but the girls decided to wait until Molly was with us, and shoot the movie. I was glad they weren't afraid of trying new things.

Watching the girls with Pepper, I briefly remembered when we had met, and how shy they were at first. Memories of our first sexual encounters, the movies, and everything that had happened since brought a smile to my face, and an erection to my cock! We decided it was time for bed, and Lyssa won the coin toss we did each night to determine which of the girls would go first with me. Tonight, as it was discovered, would yield something different.

Megan had started her period today. Lyssa went to bed with me, and Megan took a hot bath, then decided to sleep in her bed. Lyssa came in with me, and we made love for the first time. Not just sex, but passionate, lovemaking. I had done this with both girls at different times. We would find out a little over a month later, that with her recently having started her period also had one other complication: she was extremely fertile and so was I. My little Lyssa became pregnant that night. But, that's another story. (and yes, we did include that in a movie).

Because Megan had not been having periods very long, hers didn't last very long. Most of her bleeding had stopped after only two days. She was ready for the others to return on Saturday. Molly was anxious to meet Pepper, but the boys were unable to make it back. Their football coach required some extra practice after losing the Friday night game. Megan and Lyssa were disappointed, but we decided to go ahead. Megan would play my assistant as she had done in the first bondage film that we had done with Lyssa.

The set was simple. Molly and Lyssa were dressed in the rags that would come apart easily when they were whipped. Megan had kept Lyssa in her role from before and suggested we do a part 2 to the previous movie since we had received such great reviews. Molly was a new servant girl who was being punished for not following orders.

The scene opened with Molly's hands tied overhead. She was stretched so that she was standing on tip-toes. Megan and I enter with Lyssa following. She is being led by her sister by a choke chain type leash

"Our new girl here has decided not to follow the rules. You should have explained the consequences to her a little better. Because you didn't, you will be punished as well," I tell Lyssa.

She begs for mercy, but Megan gives the choke chain a jerk and it silences her. I pick up the cat-o-nine-tails and approach Molly. She is wiggling, in a feeble attempt to get away, and begs for mercy. My response is to whip her, shredding her clothing. Her barely-teen body is slowly revealed, along with the red welts over her bottom and pussy. I even whipped across her tits. She screamed, which resulted in my twisting and tugging on her nipples. Those beautiful, eraser-sized nipples.

As a twist, Megan had suggested that she use a strap-on dildo to fuck Lyssa. When I released Molly from the hook she had been hanging from, I pulled her across a sawhorse, then used her hair to hold her head up. This would force her to watch Lyssa being abused by Megan.

As Megan was taking Lyssa, I took Molly. More screams, pleading for us to stop. Stop I did. As soon as I had unloaded into Molly. I moved in front of her, made her clean my cock, then told Megan to stop. She looked at me, but complied. I told her I would return, and to leave the skank bent over.

I returned with Pepper. When we walked in, Lyssa and Molly both gasped in shock. They were great little actors. Of course, when I came back in, Megan had moved to Molly and was fucking her with the dildo. Maybe Molly's look was more pleasure?

I ordered Pepper simply to "mount." He moved to Lyssa, and did just that. She knew better than to move, or resist. She was, after all, a good little slave. The big shepherd found his mark, and his thick, red cock began plunging in and out of the 11 year old girl.

Her cries went from shock, to pain, to, eventually, pleasure. I knew he had to be hurting her. Some older girls complained that he was too big. Lyssa had begged for the chance to try, so she was getting exactly what she had asked for. A large, shiny, red, doggy cock. Pumping in and out as only dogs can do.

When his knot started moving, I just stood and watched. My little slut took it. She screamed. LOUD! But she took the knot and everything Pepper had to give. When he came, so did she. More screams. This time, to let the world know she was cumming. Pepper stood still until his knot relaxed, then he pulled out. A stream of his cum was caught on film as it gushed from Lyssa's stretched pussy.

Molly, meanwhile had cum with the pumping of Megan and her strap-on. That left Megan. Molly was instructed to lay on the floor. Lyssa was moved over her, and the girls were ordered to perform 69. Molly got her first taste of doggy cum. Lyssa got the privilege of sucking my cum from Molly's pussy.

As the girls went after each other, I bent Megan over the sawhorse and fucked her doggy style. Once we had both cum, I instructed the girls to lay with the tops of their heads touching. Megan squatted over each girl, allowing my cum to drip from her pussy and onto waiting tongues.

Before we ended the shoot for the day, Pepper had fucked Molly as well. Megan decided to hold off for now, and she hadn't written it into the script for her to be used by the dog. Molly screamed, just not as loudly as Lyssa. Pepper didn't really care. He loved human pussy as much as any human male. Once he was satisfied, he licked his cock and went to sleep.

The last take for today was of our "slaves" being told they would now allow Pepper to service them at any time he showed an interest. They were very submissive. I had to wonder how much was acting.
