Incest Seduction/Kim gives Dawn a lap dance

"Do Dawn too..." you whisper as Kim lingers next to your body again.

She pulls away after registering what you said. There is obvious uncertainty in her expression. You have no doubt that her apparent "interest" in you has been the driving force behind her performance until now. The prospect of doing much of the same to her older sister has Kim questioning herself.

"Are you done yet?"

You look over at Dawn. That remark wasn't as snarky or mean as it could have been. All things considered it was downright polite, at least for Dawn. But she looks a bit off to you. She's sitting very tensely at the other end of the couch. One hand is sandwiched between her thighs in her pajama pants while the other is over top of her cami resting just below her breasts, her fingers tucked under her opposite arm. Her ears are red. Her face is flush. She looks warm, despite wearing so little.

"N-no!" is your youngest sister's terse reply.

She pushes off of you and the couch then struts over-zealously the few measly steps to get in front of Dawn. Kim pauses again staring down at her sister and not-so-confidently says, "It's your turn."

In response, Dawn slowly untucks herself, resting her hands at her sides and offering up a less defensive posture. This does not embolden Kim however. She turns away shamefully, raising a fingernail to her lips to nibble nervously. She then glances at you. You urge her with your eyes. It's obvious to you that Dawn is bothered - in a good way - by what she's seen so far. That should mean that you and Kim are one more lap dance away from conquering Dawn the Tattletale!

After a few more tense seconds Kim begins to sway her hips. You nearly give an audible sigh as your little sis warms herself up again. But there's more to this than escaping punishment. The image alone of what is about to happen already has a bit of pre-cum leaking from your dick.

Kim sways and gyrates her lower half at an increasing pace. The lithe little teen has fewer curves than her older sister but she manages to expose more and more detail from her sultry form with every movement. Soon her hands begin to roam across her naked chest, her arousal only serving to encourage her motion.

With a burst of energy Kim spins in place with her arms in the air flashing her sister and catching a glimpse of her as she rotates. Kim stops herself when facing away from the couch again, then looks over her shoulder demurely with a grin.

The loud smack startles you even though you watch Kim's hand land on her own ass. What likely distracted you was having her stare you down as she did it. Seemingly satisfied with herself, her confidence boosted, she finally turns around to face her big sister who looks no less bothered now than she did a minute ago. You hope Kim realizes the power she holds in this moment, but in any case she pushes ahead all the same.

Dawn's lap dance goes much the same as yours did. Kim mounts her sister, both knees on the couch, and gyrates and thrusts away haphazardly. She whips her hair at Dawn repeatedly, pushes her modest tits at Dawn's face, and claws clumsily at Dawn's pajamas. The difference from your lap dance however is that Dawn is participating. You would have considered yourself an exemplary patron of your youngest sister's services, but not Dawn. She quickly has her hands all over your sister. They run up and down Kim's legs and over her yoga shorts. She holds her palm against Kim's taught stomach for quite a while then hurriedly darts upward to squeeze her tits more than once. Dawn was a terrible customer, but her eager groping only seemed to strengthen Kim's resolve.

Kim stood up on the couch just as she had with you and began to gyrate and dance with her pelvis right in Dawn's face. Perhaps Kim wanted some distance from her sister, to show her who was in control. But Dawn doesn't stop groping. In fact she takes it one step further. She slips her fingers into either side of Kim's shorts and yanks down on her sister's last piece of clothing.

The dancing stops immediately. Kim stares down in shock at her sister's boldness. Dawn stares back, but steals glance after glance of Kim's slick pussy mound. You aren't that far away, but you aren't as close as you'd like to be and aren't at the most favorable of angles. But from what you can see Kim doesn't have the slightest trace of pubic hair. You briefly ponder whether she waxes or if she really is still hairless.

"Now are you done?" Dawn asks again. It's more of a taunt this time, daring her to continue.

Kim bites her lip, awkwardly steps out of her yoga shorts, then throws them in your direction. They land next to you, close enough to get another hint of her strangely alluring scent.

"I'm done when I'm done," replies Kim. She's trying to sound authoritative but it comes off a bit bratty. Regardless, she clutches a fistful of Dawn's hair and pulls her sister right against her snatch. Kim bucks and thrusts a few times with an almost angry expression, face-fucking her older sister. She turns her head towards you, her eyes fierce and lustful once more. You give your dick a squeeze through your pants which she seems to appreciate. But then Dawn gets her attention.

Dawn, her hands on Kim's thighs, finally pushes herself away from her sister's crotch. She grabs Kim's hand at her wrist and rips the young girl's grip from her hair. Still holding Kim's wrist, Dawn pulls down hard almost causing her little sister to collapse onto the couch, but instead Kim bends at her knees and waist until the two are face to face. Kim has a frightened expression for the briefest of moments, clearly startled by her sissy's outburst. But it is brief because Dawn immediately leans into Kim and kisses her.

You're just as shocked as Kim. Your jaw literally drops open while Kim drops her bare butt onto her sister's legs. Kim's entire body goes limp. Her eyes slowly close as Dawn sensually assaults her lips. Your first thought is you asking yourself why this is happening. Your second thought is about Kim's pussy juices on Dawn's lips and wondering whether Kim had ever tasted herself before...

Keep watching. No sense in ruining this!

You can't. You gotta. Whip out your dick and jerk it to your sisters.
