Hot Summer Job/Help Bree fuck Kylie
You chuckle aloud. "Yes! All the way yes!"
Kylie's demeanor changes a bit. She was much more excited when it was just your sister involved.
"Yay!" yells Bree. "So where do we start?"
"You have to turn it on first," instructs Kylie.
"Huh? Turn what on?"
"Your vibrator."
Bree leans toward you, whispering, "I don't know what that is."
"Oh! I know how!" Larissa offers, crawling up behind Bree. "At least I think I do."
As Larissa pokes at the battery pack you grab a bottle of lube.
"The first thing you need is to put some of this on. It'll make your dick slippery so it moves easier."
Bree giggles at your dirty description, despite her far more debaucherous reality. You pop the top of the bottle and squirt some lube into your palm. Then you reach toward Bree's dick.
"No! Lemme do mine. You can do yours!" orders Bree. She snatches the bottle from you and meticulously starts dripping small drops onto the strap-on. She misses more often than she hits it, and of course giggles the entire time.
It's hard to say no to a handful of lube. You pull down your shorts and your boxers to free your already fully inflated cock. You're no slouch in the dick department; you'd say a little above average. But Bree is sporting an 8-9 inch monster which looks even more gargantuan attached to her tiny frame. You're surprised that the strap-on even offers enough adjustments for it to fit a ten year old properly.
Her forearm of a cock (literally) slopes gently toward the floor. She tosses the bottle aside and places her hands on it, sloppily finger painting her pink member. Dipping your meat into the cool liquid in your palm is almost refreshing.
"OOOoo! AH! WOOah.... OOOh.... ooooh...."
The sudden crazy sounds are coming from your sister.
"I got it!" Rissa announces proudly.
"It's... rubbing... so fast..." Bree eeks out, her entire body having become very tense. You all stare at Bree, all equally aroused by the moaning grade schooler contorting her face as the small vibrator inside her goes to work. After a few moments she manages to focus her eyes again and look in your direction.
"...w-what's next?"
You've already stripped yourself of your clothes by the time your sister wants to continue. You're stiff as steel watching your little sis get forcibly pleasured by a toy that she cannot escape from, buckled and strapped to her body. But you can hardly wait to see her fuck Kylie with that thing.
"Uhh, well, any extra lube can go on the girl."
Kylie glances between you and Bree. She bites her lip nervously as you kneel down in front of her. Softly, you press your palm over her crotch and gently knead her sex with your hand. She watches you warily, propped up on her elbows.
You pull your hand down until the tips of your digits are pointed at her slit. Her slightly puffy lips are pillowy soft and give way with the slightest pressure. Kylie adjusts herself just as you slide up again and push your middle finger inside her. She gasps, not expecting the intruder. Your ring and index finger press down along the length of her labia while your inserted finger dives deeper.
"Of course, if you can, make sure you get some inside too." Your finger bottoms out on your knuckle, your cue to pull back.
You slide completely in and out of Kylie a few times, testing the waters and spreading the lube. When she doesn't kick you away or voice her apparent annoyance you press on. You find a steady rhythm in your movements, stroking her lips with two fingers while fucking her with another. Her vagina grips your finger with an intense focus, little ridges and bumps pressing in from all sides. It takes a minute, but Kylie slowly begins to enjoy herself; her eyelids droop, her body - and her pussy - relaxes. Of course it's then that you realize how long you've been fingering her.
"Bree... Bree?"
You look over your shoulder at your sister. She's kneeling at the edge of the mattress, her body hunched forward, her breathing ragged. Both of her hands are on her dick, pulling on it in sync with short little humping movements from her rolling pelvis. She can't really pull on the dick though, and not because of how well secured it is. The harness does move a little bit, but her lubed up cock is difficult to grip which makes her small hands just slide up and down it's length in short jerks with each pull. Your sis is jerking off her slippery cock and could very well cum at any moment.
Meanwhile Larissa is sitting nearby quickly rubbing the outside of her shorts. She's studying Bree's orgasmic expressions and making some of her own.
