You Do Accidentally

Your thrusting fingers strike a chord within you and your body coils back into the office chair. You feel your mouth shout out "Yes!" which the person at the door takes as an invitation. The door begins to swing open as you try and fail to work up the willpower to keep from pistoning in and out of your needy snatch. The door opens and standing across the room from you is your sister, dressed in a tan business outfit that seems out of place on her younger body.

"Sarah...?" you manage, body for once saying what your brain asked it to.

She smiles. "Miss Brown, is now the best time for that? You'll be late for the meeting." She looks down at the fingers of your right hand as they continue to **** your sex.

Sarah, get me the fuck out of this body now!

"Sarah, I need to fuck you! Pleeeease don't make me wait any longer!" Your left hand flies up to your tits and starts to **** them violently as you try to keep both them and your anger in check. Sarah smiles brightly at you, committed to playing dumb as you work yourself over, splayed out on the office chair.

"Of course!" she chirps, smirking. "What else are interns for?"

You manage to get your hands to calm down and begin to start dressing you again, when you see your stepsister start to raise her skirt. The moment you catch a pink flash of panty peek out from beneath it, a jolt passes through your body. You can feel the need pressing against your skin, running like an electrical field around your entire body. As more and more of the lacy number comes into view, your body removes any bit of control you had.

The bra you're wearing presses into your back as you spill forward onto your hands and knees, breasts bouncing roughly beneath you as you crane your head upwards, looking directly into Sarah's crotch. When did she get so close? You can feel your tits swing slowly from side to side as you move the last few feet towards her, every curve of your ass modeled by the material of your skirt as it strains into the air.

"Good girl," she says, running her hand through your hair. She presses you face-first against her panties and you can feel her getting wet as your own hot breath bounces back across your face. Your body can't take any more of it and you feel your tongue dart out of your mouth. The instant it makes contact, you swear your eyes roll back in your head from the sheer pleasure that courses across your body. You vaguely notice yourself being held back at the head, but your thoughts are in a mess from the sensation emanating from your tongue, as well as that caused by your crotch grinding against the rough carpet of the floor.

Sarah laughs. "Perfect, exactly like I wanted! Now, Miss Brown, I'll be excited to see what you have to present to us at the meeting." Winking at you, she turns and exits the room. You watch her as she leaves, unsteadily supported on your two hands, lower half slowly humping the ground.
