"I'm going to fuck you until you beg me to stop...

And then you can cum as much as you want."

That's what Mistress Luchia had told me Monday morning. I hadn't remembered it, as I thought it was just a sexy thing to say at the time. I was wrong though.

When I got home from work last night, I took a shower, had some wine, and after being forgetful again I grabbed my milking box from the corner and presented it to her.

"Will you please fuck me and milk me Mistress?" I asked.

She told me to strip, and kneel on my hands and knees on the bed. I put my head down and she got a long thin black scarf from somewhere. Mistress tied my balls and cock tightly at the base, and then she tied each long, free end to each of my ankles. I couldn't stand up straight, and I couldn't get out of my kneeling position without causing myself a lot of discomfort.

Where did she learn that?

I kept my head down as she put some analese on my ass  and then started to fuck me. It was light at first, but then it got harder. Then it got harder still. Then it was fast, and hard, and light exploded behind my eyes as I moaned and clawed at the bedsheets.

I was screaming into the pillow and biting against the pain from being fucked so hard and fast. Earlier in the day I had mentioned to her that there was a forum I'd seen that tells you how to make a home made fucking machine.

"You don't need a fucking machine. You have me. Aren't you my little bitch?"

I couldn't answer her. My concentration was on trying to keep my ass open and presented to her constantly pounding cock in my ass. A stiff, 8 inch replica cock with only a slight amount of give.

Finally I remembered how to speak. I cried out "Please!"

"Please What?" she asked.

"please... stop..."

That was the end. She did. She stopped fucking me.

I was relieved when she pulled her cock out of me, but at the same time it felt empty after being so abused. I couldn't move. I couldn't think at the time. I just stayed collapsed on the bed until I heard the shower start in the bathroom.

I went to join Mistress and we talked about how it went. I was still dazed and fuzzy, which felt good.

She asked me if she broke me, and I nodded, as I had never begged anyone to stop anything before. She also said that next time she wouldn't stop when I begged her too.

25 minutes. She was disappointed though. She was shooting for 30.

Once we were out of the shower she took me back to the bed and started playing with my cock. I wasn't sure if I could do any more, but I managed after a bit of her toying with me.

She pushed me onto my back and put my inside of her and started to ride me, hard and fast. I asked if I was allowed to cum and she leaned over and pushed her body against mine. Mistress breathed her answer into my ear "I promised this morning that I was going to fuck you until you beg me to stop, and then you can cum as much as you want."

It wasn't much longer before I exploded inside of her.

Monday is my favorite day.
