Fully Her

With Katherine bent over in front of the toilet you place your hands on either side of her hips and turn her body at an angle so that you can kneel behind her.

“What the fuck are you doing?” She hisses, her hand still holding the older man’s cock.

You push her skirt up exposing a tight pair of white silk panties. She doesn’t fight as you yank them roughly down her thighs to her knees and exposing the lips of her pussy framed by neatly trimmed dark pubic hair. You reach up to the cheeks of her ass and spread them apart to reveal her puckered pink asshole.

“I’m going to slide my dick into your tight little ass Katie, and I’m going to fuck it while you suck the cum out of that cock.”

Katherine stares hatefully back at you.

“Don’t you dare!” She cries.

“I will tell them everything Katherine,” you reply as you massage her asshole with the tip of your finger. “Now put that dick back in your mouth where it belongs.”

She stares with wild hatred at you and then sucks the man’s cock back into her mouth.

With one hand holding her ass apart you push the head of your cock against her asshole, rubbing it up and down and wiping precum and Katherina’s saliva on it as lubrication. Gently at first you press, her ass clenching tight to deny you entry.

“Relax or this is really going to be bad for you,” you advise her and she belatedly acquiesces, relaxing her sphincter and letting the very tip of your cock inside.

She groans around the old man’s dick, although you’re unsure whether it’s pleasure or pain. You slide her skirt up even farther to get a good view of her ass as you begin to thrust in and out of her. You take it slowly at first, giving her ass time to respond to the stimulation and relax itself. You begin to thrust faster, your legs slapping loudly against her ass cheeks, your hands holding tightly onto her hips.

The man on the other side of the divider groans.

“Oh yeah girl,” he moans, “I’m going to cum.”

Katherine keeps her lips tightly locked around the man’s dick as he begins to cum. She moans slightly as the semen pumps across her tongue.

“Drink his load,” you tell her, thrusting even harder. “Swallow that cum for me.”

You can feel your own load churning in your testicles and as you fuck Katherine’s tight asshole, your cock making wet noises and it pistons in and out of her hot ass. Katherine releases the man’s cock with a pop and a small stream of cum trails down her lips and chin. She swallows audibly.

“Good girl,” you compliment her. “Are you ready for another one?”

She just stares at you as you pound her from behind, then she closes her eyes and lowers her head. You reach forward and grab her long black hair, pull her head upright and using the added leverage to pull yourself even deeper inside of her.

“Oh fuck, I’m gonna cum.” You groan. “I’m going to cum in your tight little ass."

You hold firmly onto her hip with one hand, still pulling her hair with the other, and begin to orgasm. Waves of pleasure radiate through your body and your cock spasms, sending jet after jet of your cum into her guts. The wet squelching of your thrusts grows louder as you slide along her increasingly cum-filled ass. After what seems like a wonderful eternity your orgasm subsides and you slowly fuck the last few drops of cum into her. You withdraw and tuck your withering dick into your boxer shorts.

“You’re even hotter than I expected Katie,” you say, offering her a hand up. She turns away, pulling her panties up and whispering something nasty to you.

“I’ll see you in two days at the office. Remember the plan.”

She doesn't reply or look at you.

You chuckle and step out of the bathroom heading towards your car. You hear a sound behind you, sort of a cross between a feral growl and a scream. You turn just in time to see Katherine, her face streaked with tears and her eyes clouded with rage. You start to say something to her and then the pen she has clutched tightly in her fist makes contact with your throat. It takes you a moment to realize that the pen has punched cleanly through your throat and embedded itself between the vertebrae of your neck. Your body goes limp and you slump to the ground. You can no longer will yourself to breathe, although by the hot spray of blood on your face you somehow know it wouldn’t matter anyway.

You fall on your side, blood pooling before your eyes. Katherine falls too, scrambling away from you into the corner, her eyes meeting yours. She’s catatonic, you see no person behind the glassy windows of her eyes. A moment later and there is no one behind yours either.
