5 days

Day 2.
I was strapped to the bed again. This time there was a fuck machine pounding me. Charlie had put a clock on the table for me. More like a cruel joke than anything else. I was supposed to be on the machine for an hour, but it felt more like ten. When he came back and turned it off I was only vaguely aware of my surroundings. Over the next few hours, I slowly came back down but not completely. I could feel my wet pussy drooling on the bed beneath me. He brought me lunch. I struggled to move because of the exhaustion. When I had finished he suggested I get some sleep before the evening session began.

Another hour on the fuck machine. After 30 minutes Charlie came back and clamped my nipples. They were as sensitive as anything and I can't remember if I screamed or moaned, everything was a blur at this point. Again he stood beside me, jerking his cock. His manly smell hit me hard, long before he even came. I felt an empty longing feeling in the pit of my stomach. Before he came said "Ohh, I'm about to cum, You want me to cum inside you? Give you a sweet sweet orgasm?" His words somehow increased my feelings, the pressure mounting but not giving me release. I could feel my body screaming for it. It wanted to cum so badly. I gritted my teeth together, willing myself to not answer. Soon warm squirts of cum hit me. All around my breasts and face. The smell again intoxicating, pushing me even further.

Day 3.
Plug in my ass today, and a smaller pink vibrator. It looked like a ping egg with a long tail. It went inside me. For a moment I thought he forgot to turn it on because he just left me there, then suddenly it started up. Wave after wave hit me. Then it stopped, and a little while later started up again. Sometimes slow, sometimes fast, and other times it pulsed up and down. 3 hours went past before he came back. Then lunch. I added small vibrators to my nipples and set them on low. "Well, I'll be back in a few more hours he said as he left me there again. The vibrator inside me kept going. I think I passed out at some point, because suddenly Charlie was there again, and a whole hour had passed on the clock.

"You feeling alright babe?" his words rang in my head. It was like being drunk, I struggled to hear what he was saying. Suddenly the world was in sharp focus again. His cock was right there in my face. I could smell it, I could see the clear precum drops at the tip. I wanted it so badly. He moved closer to me, and I leaned my head forward and took it in my mouth. Oh my god, what was I doing? He didn't **** me or anything. My body was reacting on its own. It wanted his cock. I was sucking him off as if my life depended on it. Soon he was moaning and announced his imminent climax. "Where do you want it, babe?" I wanted him inside me. I felt the empty feeling inside me. It was screaming out for him. But I still said nothing. "In your mouth then?". I couldn't stop myself. My head made a nodding motion, and then I felt the hot jets of cum fill my mouth. Still, I kept sucking. It was delicious. A euphoric sensation filled me, and knots in my stomach cried out in a mixture of hunger and agony. I think I swallowed.

Day 4.
He moved me over to a bench, I was strapped down doggy style as the fuck machine was back on. The hour passed just like it did the first time. No break, It just kept going. I had been on it for two hours. Before he untied me for lunch. He sat down on the bed, the bulge in his boxers seemed to be calling to me. I wanted him so badly. It took all my willpower to **** me from making a move. I wanted to crawl all over him and ride his cock to fill me with his cum.

Back on the bed, the pink egg-like vibrator back in. 3 more hours passed before he came back. "Where would you like it today?" he asked pulling off his boxers and stroking his cock. "Fuck me!" I screamed before I could control myself. "You want me to cum inside you?" I shook my head. He put on a condom and placed himself between my legs. Then without even removing the vibrator inside me, he pushed inside. It was just as I had expected. New levels hit me. A minute of fucking later, I heard him moan. My stomach churned over, and my whole body braced for release as I felt him twitching inside me, but... nothing came. "AHHHHH," I cried. Tears streaming down my face. The vibrator switched off. He removed the plug and loosened the restraints to my bedtime position. Before he left he took the condom off and emptied it on the mattress next to my pillow.

I went to sleep, the intoxicating smell of his cum filling my nose as I finally drifted off.

Day 5.
I was still riding the high when I woke up. The smell of cum and sweat filled the room. Every day had pushed me further, and every time I came back down, a little less. The bed was soaked, and my pussy was drooling wet. When Charlie came back that morning, I knew I had lost. Just the smell of him was enough to drive me crazy. I couldn't go on like this. I was struggling even remembering my own name. I was constantly horny, the only thing on my mind now was cock. I wanted it, no... needed it.

He was getting things ready and was about to move me around for another round on the fuck machine. "Please..." I croaked "No more... I... I..." "Something you want to say, baby?"
"I... Fuck... Fuck me." "You need to be more specific, baby. Remember the deal. Only when you ask me to," he said. I was done for, there was no resistance left in me.

"Cum inside me", I said. "You sure about that?" Dammit, don't test me now, just do it.

"Yes," I panted. "Then you will be pregnant, and be my girl forever?" Oh shit... I... I... I needed this. Was I willing to give myself up to him like this? My body answered for me.

"Yes!" I screamed without any chance of stopping myself.

He dropped his boxers and moved into the bed. Pushed my legs up towards my chest. I felt the tip of his cock touch my pussy, and immediately I was on the edge. Fuck Fuck Fuck this was worse than before. Just his precum was driving me crazy. He pushed inside "Mmmmmm, Yes!" I screamed. This was what I needed. I could feel all of my body tighten. My pussy clamping down on him, holding on to his cock for dear life. He was pistoning inside me, long slow strokes. "Fuck me harder!" I screamed. He obliged, speeding up harder faster thrusts. The tip of his cock hitting my womb. "Yes Yes yes!" I wasn't even restrained now. If anything this was the best opportunity I had to get away, but it was hopeless. My body wanted only one thing. To milk every last drop of cum from him. He pulled out. "No no no no, don't stop!" I screamed. He lifted me up and sat down on the bed. I was on top now. My hips moved on their own now, like the most natural thing in the world. I gyrated harder and faster. Panting, screaming. I heard his breath quicken. "Mmmmm, I'm about to cum," he said. "YES YES CUM INSIDE ME!" I was doing all the work now. No one was forcing me. I felt the first twitch, hot cum painted the inside of my fertile pussy. Everything went white. Days of pent-up pleasure exploded inside me. Every jet of his cum releases new waves of pleasure. Every muscle in my body was tensing up. It kept going for what felt like minutes but was probably a lot less. I collapsed down on top of him as all my muscles released their tension and had no strength left in them. It was all a blur now, I felt his tongue in my mouth. Mine in his, swirling around each other in the hottest most passionate kiss I have ever felt.
