Incest Seduction/Dawn takes over the lap dance
It takes every ounce of restraint left in you to not interrupt your sisters in one way or another. Your breathing is so shallow you've almost stopped. You're just trying to be a fly on the wall.
Kim is melting into her sister's lap. Her arms hang limply at her sides. Her legs are split by Dawn, all scrunched up with her feet in the cushions and her knees almost as high as her head. Her torso curves lazily toward Dawn. Kim has effectively been turned into a rag doll, a horny ball of nerves and confusion, and all it took was for her to strip naked and be kissed by her older sister.
Speaking of, Dawn is darting her tongue into little Kimmy's mouth. Kim is barely moving her lips compared to Dawn, who is actively exploring not only Kimberly's lips but the rest of her body as well. Dawn rubs the length of Kim's inner thigh. She gently scratches at Kim's tiny tits with speedy fingers, pawing at her mounds teasingly over and over until she finally tweaks one of her nipples. A pitiful whimper is all Kim manages to muster, still paralyzed by her older sister's actions.
But it seems Dawn is only getting warmed up. After spending quite a while kissing and teasing, she unceremoniously plunges her digits inside her little sister. You watch as Kim's entire body stiffens, her hands clenching, her eyes opening. She whimpers loudly then gasps sharply. Dawn grabs Kimberly's chin firmly with her other hand and kisses her even harder.
You have to lean forward for a better angle as Kim's legs are blocking much of your view. Dawn has shoved two of her fingers well inside her lil sissy's sopping wet pussy. Just two slender digits appear to have already filled Kim's tight virgin snatch. But Dawn isn't thrusting into her. Not especially. By the movement of her other fingers it looks like she is rubbing and massaging inside of her pussy.
Leaning back, it becomes obvious to you that Kim is trying to kiss Dawn as best she can but she is losing control of her body. Small regular shudders pulse through her petite frame. Her eyelids flutter randomly. She continues to gasp and whimper, so much so that Dawn will soon have to start breathing for her if she doesn't part her lips from Kim's. Watching your younger sister stroke your nude baby sister's g-spot only an arm's length away coaxes another spurt of pre-cum into your pants.
