The pounding was definitely having an impact. I was thrusting away and slapping your rosy bottom as often as I could. Each slap sending a tingle up your spine and a little clench to your pussy.
Your ankles and knees tied together, resting on my shoulder. A pillow under your butt and your wrists and elbows tied together forcing your head forward. You were reduced to just experiencing what I wanted you to, and you were enjoying it.
Feeling the buildup you clench your hands and ask, "Please, may I cum, Sir?"
"No," I reply, redoubling my efforts.
"Please!" urgency in your voice. In fact, permission isn't going to be a factor if I keep up.
"Don't you dare!" I say, a sparkle in my eye. I reach over and grab the vibrator and hold it to your clit with the hand that had been spanking you.
Closing your eyes, you try to control the rising wave of pleasure, but my continued thrusting and the vibrator are relentless. You fight as long as you can, but it's a losing battle and eventually the orgasm wins.
I watch your body tense, feel you squirting on me and the wonderful feel of your pussy spasming over my cock. I thrust a few more times and join you in orgasm.
Resting your legs to the side, my now softening cock still in you, you look up at me. The smile on my face both comforting and slightly worrying.
"Even without permission, in direct defiance of a direct command, you came. Not only came, but came hard and squirted. You've been very naughty pet! Lucky for you, I know how to deal with naughty pets!"
Bending over I kiss you deeply, lightly tweaking your nipples.
"First things first," I say as I position myself and present my cock to your mouth. "Clean."
You take me into your mouth and lick and suck all our juices from me. Even having come so recently I start to firm up as your tongue slips along the underside of my cock to clean my balls as well.
As wonderful as this feels, I have work to do. I untie your legs and retie them to the headboard, ankles and knees wide, fully exposing you pussy to me.
Laying on your left side I alternate between kissing your face and tits while I use my hand to hold the vibrator to your clit.
Primed from your first orgasm you quickly near your second. "Please, Sir! Permission to come!"
I place my hand around your throat and say, "Oh yes, you have permission to come. In fact, I _order_ you to come! Now!" I punctuate my command my tightening my grip on your neck.
