I put her to bed naked and let her sleep for a couple of hours. I made her sleep on top of the sheets so I could see her naked body while she slept. She slept on her side, almost in a fetal position.
I sat on a chair near the bed, also naked, and watched her. She was exquisite. I watched her flat belly slowly moving in and out with her breathing. I almost hated to wake her up. Almost.
I opened a drawer next to the bed and pulled out a set of two wrist restraints. One end of the restraints had cuffs, which I gently attached to her wrists while she slept. I attached the other end to fasteners on the corners of the bed's headboard.
I slowly pulled the restraints through the fasteners until they started to draw on her wrists. I applied gentle pressure, pulling her arms back toward the corners. Once her arms started to extend, she began to wake up.
"Wake up, little bitch. Wake up for your Daddy."
As I continued to pull on the restraints, she was forced to unfurl herself and lay on her back until her arms were stretched taut behind her. It didn't take her long to wake up fully.
She eyed me apprehensively from the bed, wondering what I had in mind. Once she was lying with her head almost at the headboard and her arms firmly restrained, I tied off the restraints.
I crawled onto the bed and sat up with my knees on either side of her torso, with my cock hanging down over her face.
"You were such a good girl earlier, little bitch. You made the right decision to put the needs of my cock over the needs of your cunt."
"Thank you, Daddy."
"Now it's time to train you to do something else for Daddy. Something that gives me a lot of pleasure."
She looked up at me expectantly, some trepidation showing on her pretty face.
"Little bitch, why do you have a tongue?"
"Daddy, the reason that I have a tongue is so that I can put it into your butthole and make you cum super hard."
"That's right, little bitch. And have you ever put your tongue into a man's butthole before?
"No, Daddy, I never have."
"Are you ready to learn how to do it properly?
"Yes, Daddy."
My cock had gotten super hard just talking about what I was about to teach her how to do.
"The first step is to suck Daddy's cock. Open your slutty little mouth."
She obeyed.
I shoved my cock into her waiting mouth. I leaned forward and fucked her face for a few minutes, gagging her. I pulled out, her drool dripping off my cock and onto her face.
"Next, service Daddy's balls."
I moved my cock forward. She obediently stuck out her tongue and began to lick my balls, slathering them with her spit for several minutes until I pulled back.
"Next, lick Daddy's taint. Do you know what the taint is?"
"No, Daddy."
"The taint is the skin between the bottom of my balls and my butthole. "Lick it, get it wet, taste it."
I moved forward and pushed my taint over her face. Once again, she didn't hesitate and started licking and slathering my taint with spit. Feeling her tongue getting close to my ass was tantalizing and sent shivers up my spine. I moved forward and backward, helping her to cover every inch of me with her tongue and spit. I pulled back and looked down at her pretty face.
"Now it's time to put your little girl tongue into Daddy's butthole. Are you ready?"
She looked a little hesitant. She took a deep breath but didn't yet reply. This was one of the requirements we had discussed at length before she had agreed to become my submissive. Ass-licking is a deal breaker for me. Any good girl should be willing to worship her Daddy's asshole. I fucking love it. It makes me cum like a fucking rocket ship.
"Little bitch, did you ever make out in the back of a car with one of your high school boyfriends? Go park somewhere remote and in the dark, get in the back seat, and stick your tongues down each other's throats? It would go on forever because you knew you weren't going to let that boy into your panties that night. You let him touch you over your clothes, but every time he tried to get under them, you'd push his hand away. So you just kissed and kissed and kissed."
"Yes, Daddy."
"That's what you will do with Daddy's butthole. Kiss it. Stick your tongue in it. Make out with it, like you made out with that boy in the back of his car at the end of a date on a Saturday night."
She shivered a little as she finally responded, "Yes, Daddy, I understand. I will make out with Daddy's butthole. I'm ready."
I moved forward further this time. I moved my thighs apart so that I could rest my asshole over her mouth, and I lowered myself down. I felt her warm, wet tongue slither into my butthole, and I let out a loud moan. Fuck, what a feeling. I pressed myself lower onto her face, and she began fucking my ass with her tongue.
I jerked off my cock while she rimmed me, moving my ass around on her face to help her work her tongue all around inside my ass. Occasionally, I would lift myself off her face to let her catch her breath. Her pretty teen face was a sweaty mess of spit. She looked up at me, clearly seeking validation of her work.
"You're doing such a good job, little bitch. Keep it up."
She nodded fervently as I lowered my asshole back onto her waiting mouth. I edged myself several times while she licked and tongue-fucked my asshole. I wanted to draw it out and enjoy her for as long as possible.
When I knew I couldn't wait any longer, I ground my asshole against her face. She moaned into my ass, pressing her face hard up into me, her tongue swirling and darting and licking in a frenzy. I jerked my cock, this time allowing myself to get to the edge and over it. I let out a huge moan as my cock began to spurt out my hot sticky cum. I caught all of it in my other hand. When I was utterly spent, I pulled back to expose her face. She was breathing hard, her face a total wet mess.
"Little bitch, that was fantastic. You made Daddy cum so good. Now you get a reward."
She beamed up at me, smiling with her whole face. She was genuinely elated to have serviced and satisfied me. To have been of good use to me. A sign of a well-trained submissive. I carefully spilled and rubbed the cum in my hand all over her face and mouth. She hungrily darted out her tongue to get as much of it into her mouth as she could.
I painted her face with my cum and then moved my hands down to her slender neck and her breasts and her flat belly, rubbing my cum into her skin. I put my cock against her lips, and she eagerly cleaned the cum off of it.
I laid down next to her on my back and let myself relax. My nut had been stratospheric. Nothing makes me cum harder than to have a pretty, young girl's tongue in my ass.
She lay on her back, panting and staring at the ceiling, a cum and spit-soaked mess. Her legs were squirmy, and she kept thrusting her hips. Her girl-cum was running down her thighs. Servicing my asshole had gotten her going again, as it should for any submissive worth her salt.
