My Girlfriend turns into a Nasty mistress

It was another day in bed with my beautiful girlfriend . We had been in a relationship for over a year now and our sex life as you can say had hit a bump..... She is a cute teen 5'5 ...good B cups.....but what was the sexiest thing about her was her ass... Coming to me I am an average looking guy 5'10 ..athletic body as I run daily....and have an average 6inch cock Coming back to the story, we were lying naked with each other and just had sex with me coming inside her but she dsnt seem to get to an orgasm this AGAIN. "Alright!! This has to stop NOW! " she said while sitting up. I give her a confused look although I knew exactly what she meant. "This is way too much for your pleasure and none for mine. You know what? I guess it's time to switch roles." She said while straddling my chest in a quick movement. As my arms are stretched upwards ,she has access to them. She quickly pins them down and reveal a handcuff from under the pillow which is under my head and locks them up. I start getting a little turned on by this so I don't struggle . "I don't know if you will like this or not, but I'm sure I will" she says with a wicked grin. The handcuffs from under the pillow have already made me realise that she planned this. She moves her bare pussy, the pussy I just came in, closer to my mouth. I see a lil of my cum trying to get out of her delicious pussy lips. "Oh dear lover, would you mind cleaning up your own cum from my pussy?" She asks in mock pout and doesn't wait for my ...

I feel her wet pussy filled with my jizz highly intoxicating so I open my mouth and stick my tongue out and try to maneuver it inside her cunt. "To eager to eat your own cum huh? Such a slut you are" . I'm shocked from listening all this filth coming out of her mouth. HER SLUT? Hell yeah I wanna be that. As I taste my cum, my predicament and her nasty talk is somehow injecting life back in my cock. Meanwhile she moves herself a little forward , my tongue now directly above her asshole. I don't hesitate and start licking without even being given the order. She moans "oh you're such a nasty whore. Licking my asshole like a cheap slut" she says and start riding my tongue which is embedded inside her sweaty asshole. I'm absolutely loving this, being smothered by her ass. She cums hard for the first time ever and I feel her sphincter muscles tightening around my tongue. She backs a little bit to sit on my chest and look in my eyes and give an evil smile. But there is something else in her eyes. It is like she knows that I'm her slave now During all this my cock has become painfully hard and I badly need a release. She notices my 6 inch hardon and smiles at me again "awww does someone wanna cum?" Pouting. "Please ..." That's all that comes out of my mouth until I receive a big slap on my cheek. "You don't speak unless you spoken to.....you got it bitch?" "Yes mistress" I say immediately regretting what I just called ...
