Back to day one again...

So it seems like my cold has finally gone (don't speak too soon, mind!), albeit not soon enough to leave me feeling well for Friday evening action. Nevertheless, yesterday afternoon Mistress R and I retired to the bedroom for some fun and I got a whole lot more than I was expecting. See, I kind of convinced myself that Mistress R had decided to beat my previous record for chastity, or that at the least she was aiming to let me cum in a fortnight's time when out long delayed Femdom session is due. So with that in mind, I wasn't really expecting much more than making her cum and then some stroking, with maybe a slim chance of her riding my cock for a while before leaving me hanging...
But no, as I lay next to Mistress R with my cock slowly hardening, I slid my fingers inbetween her legs and gently started to tease her pussy as we kissed. She reached for my cock and began stroking it as it got harder and harder, assessing it perhaps, to see if it was satisfactorily hard for what she wanted to do.
I slowly worked a finger inside her wet pussy and waited for her signal to move down between her legs and to eat her pussy until she came, but instead she squeezed my cock firmly and told me she wanted me inside her. I moved between her legs and she guided my cock into her slit, it wasn't that long ago that I was inside her but it still felt heavenly and at first I had to be a little careful (what with it being twenty days since I had cum).
This soon passed and I pushed deeper inside, settling into a nice gentle rhythm. Mistress R asked if I was getting close and I told her 'No, not yet...'. I carried on sliding my cock in and out of her silky hole and again she asked me if I was close, I replied that I still wasn't. She told me to tell me when I was.
Perhaps another minute or so passed and I started to speed up a little, gradually getting closer to the edge, and intensely aware that I had to be careful not to go steaming up to the edge because Mistress might well tell me to stop and I needed to be able to comply with her wishes.
"I'm close, Mistress." I breathed.
"Do you want to cum?" She asked.
"Yes Mistress..."
"Ask me nicely if you can and we'll see."
I was still fucking her, right on the edge and trying to compose my thoughts.
"Please may I cum Mistress?" I begged.
"Yes slave, you may cum."
I pumped my hips harder and faster and within a few seconds I felt my cock erupt inside her. It was sooooooo good. Soon the sensation was too intense and I had to stop, still savouring the feeling of coming inside her (and being on top) as I regained my composure.
Afterwards I went down on Mistress R and made her cum, leaving us both nicely sated.
I loved the way she had me tell her when I was close and only then allowed me to know whether I was to be allowed to cum or not. Maybe she decided what she wanted before I even entered her, but by keeping me in the dark it made it so much more intense for me when she finally granted permission.
So I'm back to day one again, who knows maybe this is the start of my next record, or maybe not. It's all in Mistress R's hands as always.
