Mia cums

Mia's moans grow louder and louder until she's wailing out and begging for you to keep fucking her. Then, completely unannounced she starts screaming out "Fuuuck I'm cumming!" as her pussy squirts all over your pelvis. You bring your rough pounding to a halt and look at her as she comes down from her climactic high. Eventually she looks down at you, still panting after the intensity of her orgasm.

"What's wrong?"

"If you want me to fuck you, you're gonna have to obey the same rules as your sister."

"What does that mean."

"See that slut behind you?" Mia turns round to see Tracy still kneeling on the floor pleasuring herself. Her eyes are closed now and she's biting her bottom lip as she rubs her pussy.

"She's probably been on the edge of orgasm for about 10 minutes now. But you know why she hasn't cum yet?"

"No"

"Because she needs permission to cum first. She knows she has to beg for it before I let her cum."

"You're seriously gonna make me beg for permission to cum?"

You grab her by the throat and squeeze lightly. "Absolutely whore. Why don't you watch Tracy and see how it's done."

You move your hand up to grab her jaw to turn her round to watch Tracy. "Tracy, cum for me."

Tracy opens her eyes finally and looks at you. "Thank you sir."

She starts furiously rubbing her fingers up and down across her clit, her pussy slowly starting to spray before she starts full-on squirting on the floor.

"I live to serve! I live to serve! I live to seeeeerve!"

She's panting as she comes down from her orgasmic bliss. When she finally returns to normal she continues on to her usual depraved acts and gets down on her hands and knees to start licking up her squirt juice, cleaning her mess.

You turn Mia back round to face you. "See how its done whore. Now are you gonna be a good girl and do as I say?"

Mia struggles to let out a soft "yes daddy" as you maintain your grip on her throat.

"Good girl." You start slowly working your cock in and out of her pussy again.

"Of course, you'll need to be punished for your mistake. Tell me, have you ever been fucked in the ass before Mia?"

She has a concerned look on her face. "Yeah only once, but it kinda hurt so I didn't try it again."

You give her a hard smack on the ass as she rides you, "address me properly whore."

"Sorry sir."

"Well I think it's time I gave your other hole a try."

"But..." You give her another hard smack on the ass, interrupting her train of thought.

"Yes sir."

"Good girl, Tracy, go get the lube."

Tracy looks at Mia with a smile, knowing what she's in for. Tracy had grown to love anal over the past few weeks but at first it definitely wasn't a comfortable experience. Coupling that with the fact that you had gotten used to a certain intensity of anal fucking and Tracy was a very happy slut, knowing her sister was in for a wild ride of pain, and maybe a little bit of pleasure. She crawls out of the living room as you continue bouncing Mia up and down on your cock.

It isn't long before she returns with a bottle of lube and kneels at your feet. You slow down your pounding of Mia's pussy before coming to a halt, instead making her shift her body back and forth atop your cock.

"Why don't you work some lube into her ass slut."

Tracy hesitates for a moment but then realises she's happy to take part in her sister's punishment, moving round to her rear. She squirts some lube out onto her index and middle finger. She then rubs lightly around Mia's hole before slipping one finger in and playfully rubbing some lube around the walls of her tight hole. Mia lets out a soft gasp as Tracy fingers her rear end. Then when Tracy feels she's ready, she slips a second finger into Mia's asshole, slowly preparing it for what's to come.
