Author's Note: This has always been a fantasy of mine.

Part 1

A couple of weeks ago Sir had started letting me sleep in his bed with him. He would lock my leather cuffs on my wrists and ankles, and lock my wrists together and to a tether attached somewhere around the headboard. Sir would leave enough slack so I could sleep comfortably. But as I discovered the first night, he could and would, draw up the slack so my arms were above my head. He would then clip my ankles to tethers, keeping my legs spread wide apart. Using clips instead of locks on my ankles was one way to torment me. No need for locks when I can't reach my ankles, and I'm still incapable of closing my legs.

I was sleeping and slowly came awake, and realized my arms were above my head and my legs were spread wide, and Sir was caressing my stretched body. Sir softly chuckled as I reflexively tugged against my bonds as he rubbed his hard cock against my hip and thigh. He grabbed one of my tits in his hand and squeezed it as he pinched, rolled and tugged my nipple. He took my other tit in his mouth and used his tongue and teeth on that nipple. I couldn't help but moan as I tried to writhe from his ministrations as he continued to rub his hard cock against me.

Sir gave my nipple one last pinch and tug then ran his hand down stomach to brush around my pussy and rub my inner thigh. He brushed over my pussy and lightly circled my clit once with his finger before running his hand up my body back to my tit to grab it and play with my nipple again.

Sir tugged on my nipple with his teeth before setting it free, then lightly blowing on it before taking it in his mouth again. I moaned again arched my back as much as I could. Sir once again tugged on my nipple with his teeth before releasing it. He began tracing a lazy pattern over my body with his hand, occasionally teasing my pussy.

Sir moved so he was between my legs and began to tease my pussy in earnest with his tongue and hands. He loved to turn me into a sexually frustrated bundle of nerves, quivering under his touch.

"Sir, may I please cum?" I panted, knowing I had to ask permission, and knowing what the answer would be. Still I asked, hoping I might be granted that release. Sir lifted his head up from between my legs as his fingers still toyed with my clit and pussy. Sir didn't answer at first, watching me as his fingers worked in and out of my wet pussy. "Please Sir."

"Not right now." He finally answered. Had he said just no, or not tonight, I'd have known not to ask again. But since he said not right now, I knew I'd be able to ask again and possibly be granted the permission to orgasm.

Sir was watching me intently as his fingers fucked my needy pussy, and one slipped into my ass hole, making me gasp and moan. Now he was finger fucking both holes, making me moan and try to buck my hips and help. He chuckled again at me.

"You like that, don't you? You dirty slut." I whimpered as he used his fingers on his other hand to pinch, roll and tug on my clit. "Answer me, slut."

"Yes Sir. I like that." I gasped.

"Tell me why you like that." Sir began alternating between slow, easy strokes and rapid thrusts.

"I like that Sir, because I'm a dirty slut." I told him, my eyes closed, focusing on the pleasure in my pussy.

"Look at me and tell me." Sir ordered, keeping me on the edge.

I opened my eyes and looked at him. "I like that Sir, because I'm a dirty slut." I moaned again as he smiled and sped up. I closed my eyes again.

"Yes you are. You know why you're a dirty slut?" He asked, still changing up his rhythm. "Look at me and tell me why you're a dirty slut."

I looked at him again. "I'm a dirty slut because I like things in my ass and for it to be finger fucked. And I like to be fucked." I told him, feeling humiliated at having to tell him as he was fingering fucking my ass hole. He liked to humiliate me and make me humiliate myself by having to beg and tell him things like I just had. He also knew I liked the humiliation and it was something of a turn on for me.

"Do you want to be fucked?" Sir asked.

"Yes Sir, please. Please fuck me." I asked. Sir pulled his fingers out of me and got up.

"Please Sir, please. Please fuck me. Please fuck and use your dirty slut." I begged as he walked out of the room.

My empty, wanting pussy was tingling in anticipation and my ass hole felt empty and lonely. And I was bound tight, unable to reach my pussy and ease its craving.

Finally Sir came back in with his hands behind his back and his cock standing tall and hard. As much as I wanted to be filled and fucked and used, I knew to stay silent. Sir stood by the bed, looking at me staring at his hard cock as I thought about it filling my pussy.

"You want your holes filled like the dirty slut you are?" Sir asked.

"Yes Sir. Please fill my holes like the dirty slut I am." I told him, feeling my pussy quiver.

"Open your mouth." Sir ordered. I did. Sir didn't do or say anything as I obediently held my mouth open. "Close your eyes." He finally said. I did, lying there with my eyes closed and my mouth open. I thought Sir would put a gag on me.

Finally I felt something go into my mouth, and realized it was a fake cock. It was relatively small and didn't trigger my gag reflex when it was all the way in with the fake balls resting on my chin.

I then felt something circle around my wet pussy, then push under me to my ass hole. I tried to raise my hips and help as a plug pushed against my hole then slip in. Sir pushed and tugged on it to seat it to his satisfaction, which caused me to moan around the fake cock in my mouth.

"You like those holes filled, dirty slut?" Sir asked.

"Yes Sir, thank you." I tried to say around the cock in my mouth.

"Do you want your last hole filled?" Sir asked.

"Yes, Sir. Please." I tried to answer. I felt something that was hard and not Sir's cock push into my pussy. I was both happy to have my pussy full and disappointed it wasn't Sir's cock to fuck me.

"Do you like that in your hole?" Sir asked. I knew it was something of a trick question. Whether I said yes or no, he wouldn't fuck me. If I said yes, he'd leave the dildo in me. If I said no, he'd take it out and leave my pussy empty and wanting.

"I'd rather have Sir's cock in my hole." I answered. Sir chuckled as he pulled the dildo out with a wet, sucking sound.

"Do you want me to fuck you?" Sir asked.

"Yes, please Sir. Please fuck me. Please fuck your dirty slut." I tried to beg around the cock in my mouth.

"Oh, yes. You dirty slut." Sir said, slowly sliding his cock into my waiting pussy as I made a quiet sound of contentment in my throat. He pushed it all the way in and held it there. "Slut." He told me, then started a slow pace of fucking me.

As his thrusts became more aggressive and faster, the fake balls of the fake cock in my mouth began moving and bouncing on my chin, helping me back towards orgasm.

"You dirty, fucking slut." Sir told me as he fucked me. "Look at me whore." Sir ordered. I opened my eyes and looked at him. "You're a dirty fucking slut aren't you? You like having a fake cock in your mouth and your ass hole filled while being fucked, don't you?"

"Yes Sir." I tried to answer as he changed up his rhythm. "Sir, may I please cum?" I tried to ask permission.

"Why?" He asked.

"Because I'm a dirty slut and being fucked with a fake cock in my mouth and my ass hole filled makes me need to cum. Please Sir, may your dirty slut please cum?" I begged, then moaned.

"When I tell you to." Sir told me, then started pounding into me hard. "Dirty, fucking slut." He emphasized with his thrusting. "Dirty whore." He slammed into me as hard and as far as he could and kept pushing. "Fucking dirty slutty whore." He started to cum. "Cum now you dirty slut." He pinched one of my nipples and twisted it. I tried to cry out and get my nipple away as kept cumming and my orgasm hit.

When my orgasm finally finished, Sir told me to look at him and I opened my eyes and did.

"Dirty, fucking slut." Sir called me, then pulled out of my pussy with a wet noise.

Sir got up off the bed and left the room for a minute. When he came back in he clipped my ankles together before getting into bed and turning out the light, leaving my mouth and ass hole filled and my pussy empty and wanting more.
