Prompt:
Vegacest with Cat secretly watching and masturbating. Maybe from Cat's POV?

Warning: Incest Porn!

I'd heard the rumors. Everyone has. So when Tori's parents went away for the weekend and I was staying overnight I was secretly watching for some sign.

Nothing, I saw nothing that seemed strange. Then Tori woke me up in the middle of the night, sneaking out. So I followed her.

I was glad I did when she stopped at Trina's room and walked in.

Trina met her at the door, naked and grabbed her off her feet, flopping backward into a recliner she had in the corner and pulling her sister into her lap. "Come tell big sister what you need," She said.

Tori laughed and said. "You know what your little sister always needs?"

Trina chuckled. "I don't know whether that's adorable or sick, Tori. But I'm going to go with I've got better uses for your mouth than talking."

Trina continued to kiss her sister. Running her fingers through her hair as her other hand possessively wrapped around the back of her neck. The kissing itself was also far from gentle as Trina's lips parted and her tongue pushed out to explore Tori's mouth.

Trina's hands became bolder before my eyes as they began to grope Tori. Grabbing and squeezing her sister's boobs and bottom almost frantically. Tori began to grind her herself slowly into Trina's lap. Her own hands cupping Trina's full firm tits squezzing and pulling lightly on her nipples

Trina impatient and filled with lust had pulled Toris nightgown open. Kissing Tori's small perfect breasts and sucking on her tiny chocolate mini-kiss nipples. The tip of her tongue reaching down as far as she could ,Trina licked from just above Tori's belly button to her caramel marshmallow puff boobs.

I started to squeeze my own tinier but more adorable puffs. Then one hand reaching down and sliding into my pajama bottoms finding my already slippy hot slit, Just cupping and squeezing it to start.

Tori leaned in and began sucking and kissing Trina's neck as she ground on her. First on one side then when Trina went for the other boob Tori would sit back pushing them forward, then kissing on the other side. Trina pushed the top half of Tori's nightgown off so it pooled at her waist.

I slipped my middle finger just a little inside, to the first knuckle. Tickling my pussy with the fingertip.

The girls took turns suckling at each others boobies but I guess Trina couldn't bear it and she got up, not quite lifting tori completely, but lifting her partially and turning, putting her on the chair where she was.

She turned Tori and placed her back on the chair facing the back with her hands on the top of the chair, kind of like on her hands and knees. Trina pulled Tori's nightgown off completely.

As I watched Trina come in from behind Tori, as she knelt there on the chair, I slid my finger inside completely. I was willing to commit a little more to playing along while watching them because the chair had rotated a quarter turn in the shift and while I wasnt in the perfect viewing spot, I was in a good place as long as no one opened the door suddenly.

Trina's hands gripped Tori's hips bringing her soft hairless slit toward her mouth. Kissing her plump lips, already glossed with excitement. Then she skated the tip of her tongue over, kissing gently before going harder and deeper with her exploring tongue. Moaning softly in the back of her throat with the pleasure of tasting her sister's sweetness. Tasting her and clearly taking as much pleasure as she gave.

Tori moaned and called out as Trina fully made out with her pussy. A simple strategy but not one I could say I would have thought of. Her tongue lapping at Tori's smooth soft lips and tongueing the slick walls of her - i dont know. what my nasty brother would call her sopping fuckhole. Consensual incest is a whole different world.

Tori's pleasure juices dewing up on the walls only to be licked away by Trina's tongue. Before Trina moved her tongue back to tickle teasingly at the entrance to her sister's puckered pink bottomhole.

As Trina seemed commited to this new tongue placement and began to finger her sister I started fingering myself with two, and the thumb of the other hand rimming my butthole with a sensation that is totally new but I could definitely get used to. Tori moaned and pushed back against Trina's exploring tongue and fingers.

As I slipped my thumb inside to mimic Trina's eager and inserted tongue, I felt my first orgasm of the night that had been building suddenly crest and release.. Luckily Tori had the same idea so her moans more than covered my heavy breathing as I rode it out.
