Incest Seduction/Jerk off to your sisters
This is amazing. This is wrong. This is so incredibly hot.
Fuck it.
Pushing down the elastic of your sweats your diamond dick immediately pops up into the air. You grip yourself firmly but pump your hand slowly, not wanting to blow your load too quickly, or for that matter interrupt your sisters.
Kim sits limply in Dawn's lap, shocked into inaction by the intense kiss. Dawn's hands roam and grope her younger sister's naked body. Her soft touch coaxes equally soft whimpers and the occasional shudder from Kim. Your youngest sister looks confused and uncertain but she is willing, in one way or another, to let this happen.
You sit there gently beating your meat and studying your youngest sister's naked form when you realize that she's watching you out of the corner of her eye. Your hand stops, as if you've been caught stealing from the cookie jar. She tilts her head towards you, locking eyes with you while Dawn continues to explore her. Brazen or stupid, you slowly move your hand over the length of your cock, teasing or even daring her to do something about it.
Unexpectedly, she does.
Leaning into Dawn, little Kimmy kisses her older sister with a fervent desire. A desire for more.
It's now Dawn's turn to be surprised. Her hands rest on Kim's midsection while Kim grabs Dawn's head in her hands and assaults her sister's mouth with her tongue. This only lasts a few seconds before Kim claws at Dawn's pajamas. The cami comes off swiftly, and probably would have been torn off if Dawn hadn't lifted her arms into the air in time. Kim spends as little time on Dawn's pajama pants. She's only able to slide them halfway off of Dawn's ass before she decides it simply isn't necessary and slips a hand down the front of them instead.
Dawn's arms shoot down to the couch pushing down hard as she arches her back and twists her pelvis. You can only imagine that Kim parted her sister's vulva and pushed deep inside her from the pitiful little shakes she is exhibiting. Dawn's freed breasts jiggle happily with these sharp movements. She's a heathy C cup, although comparing your sisters' tits side by side has you a bit confused. You're not sure if Dawn looks larger than normal or Kimmy looks even smaller. Either way, Dawn's round perky breasts and slightly puffy nipples are a beautiful contrast to Kim's younger, daintier assets.
It's not long before Dawn catches up to Kim's burst of enthusiasm. She cups and kneads her little sissy's petite tits then rubs up and down the length of her hairless slit with nimble fingers.
With each of them masturbating the other they keep getting surprised looks of pleasure when their fingers hit just the right spot. Precum is already lubricating your hand. The slick sensation brings you to imagine yourself sliding inside of your sisters...
You're going to explode. You can't stop it.
