Dominate her

I go over to a chair and sit in it. "Over my knee!" a bark.

She is genuinely shocked, I can see it on her face. But she slowly walks over and hesitantly bends over my knee. "Why are you over my knee slut?"

"Because I am a bad slut and need to be punished"

"And how should you be punished?"

"I need to be spanked, Sir"

"That's right slut" bringing my hand down on her ass with a sharp smack. Just hard enough to sting, not hurt. She whimpers. Another. Another. She is squirming now, her breathing hard. Two more and then switching to the other cheek for five more. I can smell her arousal, she is panting and squirming making no attempt to hide her desire. I slide a finger into her cunt to test "My dirty slut likes to be punished, don't you?"

"Yes, Master" I note the change in title, the increased submission. Interesting, she's really into this. I finger fuck her as my hard-on is pushing against her stomach.

"Pease Master, I want you cock"

"Please Master"

"Please..." a whimper now

Her cries become more **** with desire as I finger her, teasing. She is truly submissive now. "Go to the window, pull the curtains back so the world can see you for the slut you are"

I can see the hesitation in her face, but she does it. A bot of me is amazed. I walk up behind her and in the moment I feel adrenaline surging through my body and I put my hands under her legs lifting her up so that her upper body is pressed against the glass and her ass is pushed back, pussy exposed and ****. She is completely off the floor, held weight carried by my arms under her thighs. She is completely helpless.

I ram my cock into her pussy and proceed to fuck her hard, driven by desire and also a sense of urgency knowing I can't hold her for long. Her face and boobs are pressed against the glass and I acan tell she feels helpless and **** as I pound her for anyone to watch.

The strain on my body is intense but I am driven on. I can feel her spasming on my cock as she cums, again and again. I lower her to the floor a fuck her doggy style, still facing out the window, the reflected light from the room stopping us seeing through the glass. The entire world could be watching for all we know. She just keeps cumming. "FUCK ME MASTER!", like a chant, begging over and over.

I fuck her hard, driven on by pure animalistic lust and back arching, a growl leaving my mouth, I cum deep inside her. I collapse on top of her lying on the floor, both of us limp.

We must lie there for 5 minutes, I may have even passed out. Eventually she looks at me with her normal loving smile "That was wonderful my love". We go to bed, cuddle, and fall into a deep sleep. I have never loved her more.
