Hot Summer Job/Ask your sis about her going commando
"Wait, where's..."
You slide one hand up her thigh and onto her butt. You give her handful of a cheek a contemplative squeeze then move your fingers across her crack in a deliberate fashion, as if you're having a hard time figuring out what's going on. With your hand on her bare backside, Bree's face is turning pink.
"Is this a new form of wedgie protection? Because it's super effective."
Bree tries to hold back a grin, unable to make eye contact with you. "...noooo."
"It's hot, I'll give that to you. But this seems a tad risky for school." You slip your other hand the rest of the way up her leg, playfully bouncing and squeezing her exposed ass with your hands.
"Quit it! Lemme go..."
She lightly smacks your chest with her hands. You can't help but note how tight her legs still are around your midsection. She's not exactly trying to get away.
"Maybe, if you tell me who stole your underwear."
"No one stole them."
"Oh, okay. You gave them to a guy then?"
"No way!"
"Ah, so it was a dare?" you say with a raised eyebrow.
Your sis meets your gaze briefly, then looks down and starts picking at her nails. "Maybe."
"Wow! You played truth or dare at school?"
"No! We played at Nikki's sleepover! And she's been bugging me ever since and made me go through with it. But today she said my dress was too long and I have to do it again tomorrow or take a forfeit!"
Her sudden admission makes you grin. A part of her must have been dying to tell you about it. She's been "daring" you to do lots of things lately.
"Oh, well you can't take a forfeit. That could be way worse," you state. Bree just nods in agreement. "You could try lying your way out of it. Just wear a shorter skirt. She won't know."
"But she was flipping my dress up the whole day until I proved it! She even tried to say I was wearing panties the whole morning and only took them off to show them. But I play fair! I haven't worn anything all day..." she says almost proudly. Her bare butt squirms a little in your hands adding proof to her claim, her movements working to spread her cheeks apart.
"Well was it fun?"
"Huh?" she asks, a tad confused.
"The dare. Was it at least fun? Even if Nikki was annoying."
"I dunno... kinda," she admits with a smile, again playing with her nails. "But I can't do it tomorrow."
"Why not?"
"Cuz there's gym tomorrow! I'll be naked in front of all the girls!"
"Hey, a dare is a dare," you shoot back.
"I know that. But would you do it?"
"Sure. You can't wuss out on a dare."
"Yeah, I guess..."
