Hot Summer Job/Jump out and grab Kylie
Kylie has a comfortable lead over Larissa. It's pretty obvious her younger sister is going to have a hard time catching her. At least by herself.
You lunge forward and wrap your arms around Kylie's midsection as she whips past you. Her forward momentum swings you out behind her but you dig in quickly. Finding your footing stops her dead in her tracks, the leftover lateral momentum bringing you to swing her in your arms 180 degrees until she's pointing towards Larissa.
"You're not wearing any panties!" Larissa squeals, braking hard to not run into her sister. "I can see your pusssssy!"
As the two of you come to a full stop, your arms close in tight around Kylie's torso until your bodies are in full contact. You can feel her butt against the thighs of your jeans but you can't feel much else. You peer down one side of her body to see her shirt bunched up in your arms and her bare hip fully exposed.
"So what?! You're only wearing panties!" Kylie shoots back.
"Yeah, but you're not!" Larissa emphasizes again.
"It's not my fault!" Kylie whines, barely even moving in your arms. "You know I sleep naked!"
"Are you sleeping now?" asks Larissa, her smart ass grin displayed proudly.
"Maybe I am!" Kylie looks up over her shoulder at you. "Ry, am I dreaming?"
"I hope not," you mutter.
"Riley, hold her arms!" orders Larissa.
Kylie's hands shoot up into the air as soon as the command is uttered, as if her sister just pulled a gun on her. That definitely seems like the worst idea, turning her wrists into conveniently placed handles for you to grab. You do so without hesitation, and without bothering to ask why. Kylie gasps dramatically.
"Wait, what are you going to do?"
The younger sibling glances about, at her sister's disheveled top, her secured wrists, and at your bare chest just over her shoulder.
"You took off my top, so I want to take yours off too."
"What?!" cries Kylie with feigned shock.
Larissa swoops in and latches onto her sister's tank top. Kylie twists and bucks in response, but she's mostly just gyrating the bottom half of her body. She isn't fighting against your grip at all. After a few seconds she drops down to her knees in front of her sister. It's another ineffective decision, as Kylie's height advantage would have made it hard for Larissa to lift her shirt off, especially if you're holding Kylie's hands in the air.
"Come on Rissa," pleads the teen. "Don't take my shirt! It's all I have!"
"It's not even yours!" counters Larissa. "It's mom's! You shouldn't even be wearing it!"
Kylie slumps a bit lower as the shirt inches higher. Larissa can't keep from giggling after she lifts the tank above her sister's boobs. You don't have the best view from behind Kylie, but your dick gets harder and harder as you watch her little sister reveal more and more of her nubile form.
Groans and whines escape the teenager when the shirt reaches her chin. She shakes her head in protest, but again doesn't fight you in the slightest. Larissa takes a moment to rub the shirt in her sister's face, literally rubbing in the embarrassment. From there she quickly advances it up the captive girl's arms rendering her body completely bare. Of course Larissa can't take it all the way off while you're holding on.
