"Tyler!" I gasped, spitting the knot out of my mouth. Wes backed away, and hastily began pulling up his pants.

"Tyler, I am so, so, so sorry." Wes began to say, backing away.

"Can it, kid. Get out of here before I decide to tell my parents what I just saw."

Wes nodded, and looked over at me. "Avery..."

"Just go, Wes. I don't want you to get in trouble."

Wes gulped, and nodded. He began to run out the door, as I slid out of the bonds. I started to reach for my shirt, but Tyler slapped my hand.

I jumped back, my hand stinging. "Ow, what was that for?"

"Don't get dressed."

I nodded, and scooted away from him. My heart was pounding, but Tyler seemed to be enjoying this scenario.

"What... what do you want from me? I'll do whatever you want, just don't tell Mom and-"

Tyler shushed me. "I won't tell. As long as you do exactly as I say."

I nodded, brushing my hair out of my eyes. "Okay, okay. What do you want?"

Tyler smiled, and sat down on my bed, making the mattress rock. "From this point forward, I own you. You will whatever I saw, when I say it. If I say give me a blow, you do it. If I tell you to jack me off, you do it. If I say anything, you do it."

I smiled. As much as I didn't want to admit it, the thought of being completely subservient to a man was exciting to me. I was beginning to get wet. "Okay. I can do that, Tyler."

"One more thing. From this point, you are my sex slave. You will call me master whenever we are alone, or if I say so in public. If you break any rules, you will be punished."

"What will my punishment be, master?" I said, feeling my pussy wetter with every word."

"Whatever I want, Avery. Whatever I want."

For the next few days, nothing happened. Tyler kept giving me smiles, and I returned them. And then one night, Mom and Dad put me in charge of Chloe. Tyler said he was going out to hang with friends, but I had doubts of his true intentions.

Chloe and I were sitting on the couch, watching some television. Chloe was beginning to doze off, and I gazed over at the clock. It was 9:45, just about her bedtime. I was just about to carry her up to her bedroom, when I heard the door open. Tyler walked in, and threw his coat on a chair.

"Hello, my beautiful slave."

"Shhhh, Chloe's asleep."

For a second, Tyler looked as if he felt bad that he had been so loud. Then, the regret faded off of his face. "And?"

I looked confused. "Master, you don't want to wake her up, do you?"

"Why would it matter to me? Slave, get on your knees."

I was about to argue, when I remembered the deal.

"Yes master."

I rose from the couch, as Tyler reached for his zipper. His cock sprang forth, and I sank to my knees in front of it. Tyler's cock was much larger than Wes', so it was a bit harder to fit it all in my mouth.

I began toying with the head of his penis with my tongue. He let out a restrained moan, and pulled out. He grabbed my face, and sprayed his delicious seed all over my face. I opened my mouth, and a bit of cum shot into my mouth. I swallowed, and then heard a voice that I had been dreading to hear.

"Avery?" Chloe called, sleepily. "What are you doing?"

Tyler looked as shocked as I was, but he regained confidence. "Avery, explain to our sister what you were doing."

I looked up at him, pleading not to make him do this. He looked from me to Chloe, and nodded at me. "Go on, do it."

I took a deep breath, and turned. Chloe was sitting up now, rubbing sleep from her eyes. "Avery, what's on your face."

I sat up on the couch, and began to explain. Mom had made me promise that I would be the one to give her the talk, but I had been hoping it wouldn't be for a few more years, at least.

Slowly, I explained everything about sex to my little sister. I noticed that Tyler was actually jerking off to my story, but Chloe didn't notice.

I finished, and looked into the young girl's eyes. They were wide open, but not with repulsion as I had expected. She looked, eager and excited. "Can I try what you were doing with Tyler? I wanna be just like you, Avery!"

I was speechless, but Tyler stood up. "Sure, sis. Here's what you have to do." He bent in close, and whispered something in Chloe's ear. She looked very excited, and I was absolutely gobsmacked.

Tyler stood up, and walked over to his coat. He pulled something out of his pocket... a ball-gag. He tossed it to me, and told me to put it on. I stood to do it, and I felt Chloe pull my panties down underneath my skirt. Tyler had pulled another thing out of his pocket, and handed it to Chloe, but I hadn't seen what it was.

"On your hands and knees, slave." I obeyed, and felt cold air on my bare bottom. My rear was on full display, and I was dripping in anticipation, literally. I felt Tyler's large cock thrust into my ass, and I moaned into the gag. I felt something pushing on my vagina as well, and when I looked down, I saw Chloe holding an enormous dildo, pushing it into my pussy. It was if I was being stretched apart, and I loved it. And then, I heard a click.

Chloe had turned the vibrator on, with the fake dick 5 inches deep into my vagina. She pushed it in farther, and I shrieked in delight.

I felt hands, reaching up my shirt, through my bra and squeezing my petite tits. I orgasmed, over and over before I felt Tyler's cock shoot out streams of cum into my ass, and Chloe pulled the dildo out of my vagina. I was gasping for air, when Tyler pulled the gag out. "Clean up this mess, slave."

Chloe giggled. "Yeah, slave."

I felt Tyler lean in close as Chloe ran off to bed.

"You know, I didn't even tell her to turn the vibrator on."

And with that, he walked off to his bedroom, leaving me right there on the floor, lying in a pool of my own juices with Tyler's dripping out of my ass.
