Megan and I had gone back upstairs and showered after the "orientation" of Anna and Mari. Lyssa had remained with them, attaching their new collars and giving them some instructions.

We returned to the main living area and found the three girls waiting on us. They were kneeling beside my chair, hands on their knees. Lyssa spoke up first.

"We are ready for you sir. They have their collars on now, and I gave them the instructed as you directed."

"Good job, Lyssa. Come sit with me," I told her as I patted my legs. She quickly climbed onto my lap, facing me. Neither Megan or myself had dressed after our shower. My vitamins were working, and I expected another erection very soon.

I looked at the new girls who were watching the two of us. Megan had turned on the cameras and was recording, as usual.

"Anna, Mari, come over here. While Lyssa and I are kissing, Anna will suck on my cock to get it ready. Mari will finger Lyssa's pussy to get her wet. Do it now."

Mari looked very unsure, but moved to obey. I had the feeling once more she would be submissive like Lyssa, while Anna seemed to be a little reluctant to comply. She did, however, move between my legs and take my flaccid member into her hands. As Lyssa started to kiss me, I could feel Anna's tongue on my cock. She may not be fully submissive just yet, but she was a pretty fair cocksucker to have only done this twice in her life.

Lyssa and I started kissing. I could tell she was enjoying the ministrations of Mari on her little cunt. She was moving against the touches of Mari, and from her kisses, I could tell she was very turned on. When Anna had me at full attention, I broke the kiss and told Lyssa to turn around. I slid down in the chair a little farther, opening my legs. Lyssa put her feet in the chair on either side of me and lowered herself to my shaft.

I looked around my lover's body to watch the girls as my cock disappeared into her cunny. I fondled her breasts as she rode my cock slowly.

"Anna, move closer and lick my balls and cock while Lyssa rides me." I could see she was unsure about getting that close to another girl, but she obeyed. I felt her tongue on my ball-sack as she began to lick, then move up my cock as Lyssa continued to ride me.

After a few minutes of this, I told the girls to stop and Anna to kneel on the floor, facing away from me. Lyssa moved next to her. I had both girls assume the "doggy position" and face away from me. Mari was instructed to lay under the girls. When I entered Lyssa again, she was to suck Lyssa's tits.

Slowly pumping into the mother of my child, I watched as she threw her head back, and lowered her body to give Mari better access. After a few strokes, I pulled out of Lyssa and moved to Anna. Mari was told to move under her sister and do the same thing to her. In this position, Anna's breasts were a little more noticeable. Mari didn't hesitate, and began to suck on big sister's titties. Anna's pussy was still extremely tight, and she grunted when I slid inside her. She was, however, very wet from what she had witnessed so far.

I could feel her pushing back against me with every thrust. Like Lyssa, she had lowered her body to allow little sis better access. The new stimulation was too much for her. Within minutes of starting to fuck her, Anna's orgasm hit.

"OHHHHHH!!! WHAT'S HAPPPENINNNNGGGG!!!" she moaned as her body bucked back against me. That was the stimulation I needed to unload. I had fully intended to take my time, but the way she squeezed my cock was too much.

As I felt my cum bubble up from my balls, I gave Anna several hard, deep strokes and unloaded several hot, thick ropes of cum into her pre-teen pussy. This was the first of many loads little Anna would get today. When I finished cumming, I sat back on my heels, my cock sliding out of Anna with a squishing noise.

"Mari, it's my turn. Come over here and clean my cock with your mouth."

She moved from under Anna, who collapsed onto the floor in a daze. I laid back and Mari hesitantly took my shaft into her small hands. Lowering her head over my cock, she began to lick the combined juices of her sister and Lyssa, along with my cum residue.

While she was on her knees over me, Megan handed Lyssa a strap-on with a small dildo attached. On the inside, it was formed to stimulate the wearer's clit. She loved using this, and I loved watching her.

Lyssa took some lube and applied it to the dildo. Moving onto her knees behind Mari, she took the girl by the hips and inserted the dildo into her. Mari's head came up when she felt Lyssa's hands. I pulled her back onto my cock. She looked frightened until Lyssa started moving. When she realized the artificial cock wasn't as large as mine, and in fact fit easily inside her, she relaxed and even raised her hips.

Lyssa was pumping into Mari when Anna looked up, having recovered from her orgasm.

"What, what, are you doing to Mari?" she asked as tried to come to her sister's defense.

"She's fucking Mari's pussy with a strap-on Anna. Mari was in the right position, and since I came inside you, Lyssa will be able to cum wearing that strap-on. Remember, girls are meant to be used and to serve others.

"Lyssa is my little girl, and she serves me. Because the two of you are here, you will serve both her and Megan, and anyone else I choose. The same goes for Mari. As I told you earlier, you will practice until you can take all of my cock, and you will remain nude unless I tell you differently. And, if Megan tells you to do anything, it is the same as coming from me. Understand? Or, do we need to go back to the punishment room?"

"Um, no sir. I understand, sir," she replied as she watched her sister getting fucked doggy-style by Lyssa. "Was that the first orgasm you've ever had?" I asked her.

Still watching Lyssa, she nodded her head.

"Good. Now you know that sex can be good. Both of my girls like it, and enjoy being used by me and whoever I tell them. They have orgasms almost every time. Lyssa is close now, and from the way Mari is sucking my cock, I'd say she's pretty close, too."

Little Mari had succeeded in taking almost all of my shaft into her mouth. The stimulation of Lyssa fucking her with the smaller dildo, and probably from watching the rest of the show, had her bucking back against Lyssa as well.

I pulled Mari's head off my cock, and told Anna to take her place. She moved to my side and leaned over my cock. She was in a position that allowed her to watch her sister's orgasm build.

Mari had what was probably the first orgasm of her young life. She squealed and shuddered and Lyssa followed soon after. I told Anna she should swallow every drop. She mumbled "yes sir" and continued to suck.

She still wasn't taking more than just over half of my member into her mouth, but she did try to swallow everything when I came a few moments later. She gagged, gulped, but did swallow. When she pulled away, she wiped her mouth and sat back on her heels.

"Was that better, sir?" she asked.

"Yes, Anna. Now, after you practice more, you will be able to take it all. You and Mari may go take a nap. Lyssa will show you where you can sleep. We have much to do later this afternoon. You will have your first modeling session, and later, we have visitors coming over."

She looked up, and obviously had a question, but didn't ask it. Instead, she helped Mari from the floor and went down the hall behind Lyssa. Megan switched off the cameras and came to sit beside me in the floor.

"Modeling? Visitors? What's going on, Daddy?" she asked as she settled into my arms.

"Her mom wanted the girls to model some, so we will do that. She also wants them to learn to serve "men" as in the plural sense. David, Adam and a younger boy who has been in some of my movies will be here. The younger boy, Jamie, is more for Mari. He's not very big, so he can easily fit inside her.

"As for my two sexy, beautiful girls," I said, hugging her and giving her a kiss on the forehead, "you can help me with the cameras. Once they are finished, you can have some quality time with the boys if you want. Or, we can just let them spend the night and have their way with the girls all night.

"Tomorrow, there will be an even bigger group. During the day tomorrow, I want you and Lyssa to work with them and help them learn to deep throat. You both do such a great job."

She giggled, then replied: "Anything for my daddy!"
