My sister's

"Oh Ashley, I bet you're wishing you hadn't embarrassed me in front of my guest now don't you" I squirmed as I heard the phone click again. "Sam, can you help me out, I can't see her face very well" my sister said with an evil grin.

Sam was all to happy to help her out. I grunted as he spun me around roughly. I tried to break free again but I gasped I felt him press himself up against my ass again. Without a word he rested the head of his penis between my cheeks. He didn't need to speak, I knew what he was threatening, keep resisting and I'll be walking funny for a week. I remembered what it was like to have him inside me for just a few seconds, I wasn't sure I could take him for a full session.

He pressed forward again. my whole body was **** against the glass. Of course there was one part of my body that was particularly exposed. My boobs had been squashed against the glass. My sister looked very happy as she snapped a few more picks of me.

"You look so hot" Lucy laughed "here take a look" she flipped the phone around and showed me the photos. I could clearly make out both my face and Sam's. Sam looked very pleased with himself. My body blocked most of his from view. However, as I was bent over you could get s prefect view of his face and basses purely off his expression it wouldn't take a genius to work out where he had placed another part of his body.

The most worrying part of the photo however was my expression. I looked…aroused. Like I was enjoying myself. I was guessing that the photo was taken just as Sam pressed up against me and caught me mid gasp.

"Anyway" my sister continued "here's how things are going to run from now on. Ashley you now belong to Sam"

"What the hell?" I asked

"Sam, whenever Ash interupts from now on…well…you know what to do"

"AAAAuuuuGGGHH…aaaaAAUGGH" I cried out as I felt the familiar sensation of Sam filling my ass. Sam only pushed in part of the way, he grunted as he stopped thrusting.

"From now on whenever Sam needs something, anything, you have to do it. If he wants you to clean his room, clean his room while you're naked, fuck you while you clean his room naked, you have to do. Or else these photos of him fucking you are going all around the school"

"This is amazing" Sam said under his breath. I'm glad one of us is enjoying this I though bitterly.

"Don't think you're getting off easy Sam" Lucy said "you might own my sister but guess what, I still own you, okay?"

"Yes ma'am" he said quietly

"Good boy, now finish up here, you'd better be gone by the time my friends get here" with that she turned and left the room.

Sam let go of my hips and slid out of me. He stepped out of the shower and I tried to slip out the the room but he grabbed my wrist "going somewhere?"

"No, I guess not" I said meekly

"I didn't think so. So you have to do what I say, huh"

"I don't really have much of a choice" I said. I really didn't like the sounds of everyone seeing those pictures.

"Don't worry, this will be our little secret, as long as you do something for me. Well actually, let me do something to you"
