Hot Summer Job/Finish up with the mattress
Wanting to finish what you started, you finish up with the pump for the bed then move to collect your guests' bags.
"There. Living room sleepover is official," you declare, tossing the two bags onto the firm and bouncy mattress.
Bree pulls her head off the bed to look at what hit the mattress. Her eyes open wide when she spots Kylie's bag. She crawls forward dramatically then plops herself down in front of the black backpack.
"Ha! I'm gonna wear Kylie's panties!" A belligerent sounding Bree unzips the bag but she takes pause once she peers inside. "Why is your bag full of... penises?"
"Wha?!" Kylie asks incredulously. You're not sure if she's acting, but you're as equally interested.
You lean down and reach into the bag alongside your sister. She pulls out a long floppy flesh-colored double-ended dildo. You manage to grab a pair of gags; a ring gag and a ball gag.
Kylie smacks the couch and loudly groans. "Uugh! This is mom's fault!"
Bree shakes the dildo in the air, laughing as it flops about.
"Did your mom... pack these for you?" you ask, confused. And so turned on.
"Mom sells this stuff. Like, a part time thing. But I guess I grabbed her bag instead of mine... They're basically identical!" she adds, very defensive.
You start to pull more and more stuff from the bag, laying it all out on the mattress. The topless Larissa has scooted up next to your bottomless sister. You playfully think to yourself that between them they make up one completely naked girl. You do glance repeatedly at Bree's crotch and Larissa's chest but you're as equally distracted by what you're pulling from the bag.
Handcuffs. Rope. Vibrators. All manner of lube. And none of it is packaged or priced. Some of it even looks used. It's certainly not going to be sold to anyone. You wonder if this is how Carrie demos her products.
Bree pulls out a cock ring and briefly tries to wear it like a bracelet. Then she manages to pull out another long rod.
"What's this thing?" asks Bree, holding it up in the air.
"That's a strap on," you offer a bit too willingly. Looking at all of this stuff with your sister and her friends is so insanely hot but you have a hard time letting go of your conscience. Your little sis is still so innocent. In the grand scheme of things anyway. Best you pull back a bit. "It's, um... girls use it," is all you manage to offer.
"How?" she says, pulling at the straps while her one hand firmly grips the pink shaft.
"It sorta... turns you into a boy," Kylie says, stepping up behind Bree. She's tied her top into place again, but not around her neck. Both sets of strings on her short halter top now wrap around her chest, tied off in the back.
Kylie cuddles up behind your sister. Her hands slide around Bree's waist and cross over her bare pelvis, hugging your sis right above her crotch.
"It straps right here." She illustrates the point by rubbing Bree just above her pussy lips. "They're like panties that give you a penis. They're made so girls can have all the fun that boys do."
"Cool! I wanna try it!" shouts Bree, clearly excited by Kylie's description. "Rissa, try it with me!" She hops up onto her feet and then tries to stick her leg through only to collapse back down onto the bed. Larissa laughs at the slapstick level failure much harder than it deserves.
Kylie reaches in and grabs your sister's leg. "Lemme help. I've watched mom do it before."
"I want a turn too!" hollars Larissa, bouncing on the mattress.
"I think this is a one-at-a-time thing, Rissa," you point out.
Kylie raises an eyebrow. "I'm pretty sure this is a two-at-a-time thing, Riley."
While Kylie pulls on buckles and velcro to tighten the toy and lift it up Bree's legs, the younger girl points to the inside of the leather strap about to cover her crotch. "What's this thing?"
"It's a built-in vibrator. It helps you feel good while you're doing another girl. I think this one is pretty powerful too. It has a battery pack on the back."
"But this part is sticking out," your sister adds, thumbing a protruding nub.
"It's supposed to. Here, I'll show you..."
Kylie reaches in and, without warning, spreads your sister's pussy with her fingers. Bree gasps and recoils a little, then drunkenly giggles some more. Kylie maneuvers the two inch curved nub into place between Bree's virgin labia. Then she grabs the pink dildo and pushes it against Bree's crotch.
"AAHH!"
Bree slams her hands over her open mouth. There's a moment of resistance before it pops into place, the vibrator sliding up into your sister's tight little pussy. This allows the leather strap to sit flush against Bree's crotch and for Kylie to make some final adjustments.
Your sibling grabs hold of her newly acquired penis and starts to shake it comically in front of her. Her eyes bulge open. She pauses, then shakes, then pauses again.
"I can feel it move... inside," states Bree. She looks a little mesmerized.
Larissa reaches forward and jerks on Bree's pink shaft with a loud cackle. Bree squeals and turns away, slapping her hands onto her pelvis. Her fingers rub along the edge of the strap running vertically up her crotch.
"Now what do I do?" she asks, the strap-on tightly secured in place.
"Now you fuck someone." Kylie smiles, not the least bit subtle about it.
Bree and Larissa both giggle nervously, but they look at each other hesitantly. Even with the alcohol lowering their inhibitions that is apparently a big step to take. But it's not a decision they have to make. Kylie lays down on the bed in front of Bree and takes off her underwear. It's quickly discarded, Kylie pawing at the small tuft of red hair above her slit.
"Do you want me to... do you?" asks Bree.
"Sure!" Kylie cheerfully replies. "It'll be fun, I know it!"
Bree gazes down at the older teen who is presenting herself so openly. Your sis grabs her dick cautiously, inspecting its length. Then she turns to you.
"Ry, you have one. Can you... show me how?"
