Incest Seduction/Ask Kim what she's going to do about it
Kim smiles at you coyly. She pushes herself down harder against your lap and rotates her pelvis forward and back, using her underside to gentle stroke the top of your dick through your respective clothing. Each of her hands massages the back of your neck briefly before they move down the front of your body, clawing at your chest haphazardly through your shirt. Leaning into you, her fingers begin to dip into the waist band of your sweats. You actually feel nervous now. This is starting to feel less and less like some game of chicken.
Kim pauses and smiles at you.
"I'm going to go shower!"
She pushes away, swinging her legs off of the couch and onto the floor. You sit dumbfounded as your sister walks away, pulling her pony tail out and nonchalantly shaking her hair as if she wasn't just grinding into your dick. Just before she leaves the room she turns around sporting an evil smirk.
"Have fun with that!"
You look down to see the crotch of your sweats tenting comically into the air. When you look up, Kim's gone.
What was all that? you ask yourself.
Pulling up on the waist band, you peek inside your sweats. You're definitely at full mast. You move a hand inside and give it a squeeze. You're insanely hard, but you start to wrestle it down, trying to get control.
You're not sure where any of that came from but you can't help but be disappointed; partially in yourself for allowing it to get so far, but then for not getting further with her than you did. Do you really want to have sex with your baby sister? Even Dawn is still young, but Kimmy...
You've never been more conflicted about anything before.
Might as well just sit here and watch TV. You're here for laundry after all.
You can't just sit in the living room with a raging boner. Best you take care of this.
