Hot Summer Job/Find a way out of this

You're taking this really far and you want to take it farther, but you know better. Mostly. You walk towards the stairs with a slightly exaggerated step bringing your sister's pussy to bounce against your hand the tiniest bit each time.

"Since you're in a daring mood I should give you a dare of your own."

"Uh-huh...?" Bree mutters with another jerk. As you scale the staircase the micro bounces becoming more pronounced.

"How about I dare you to clean your room?" you tease.

"Really?" she whines. "That's not fun."

"True, but you should still do it. I even started on it for you."

"Ooh... thanks!" she manages after a short sigh.

"So you really want a dare huh?"

"Well not if it's to clean!" she sneers at you playfully.

You carry your sis into her bedroom, ceasing your ministrations. That only seems to frustrate her. She jerks against your stationary hand a few times as you continue.

"Okay, well your dare was basically for me to get naked..." Bree looks away with a grin when you point that out so blatantly. "So this seems only fair. Until tomorrow night, you have to spend as much time in your room as you can. And when you're in here you have to be naked."

Bree leans away from you. "What!? Until tomorrow?"

"Yup. Tomorrow. Are you chickening out already?"

Bree glares at you comically. "Never!"

You take a few steps to the side of her room and, moving your hand out of the way, plant her butt atop her desk. You dick brushes up against the edge of it as you help lower her down. She takes her arms off of your neck and brings them down to the front of her dress, immediately pulling it down her legs to find some modesty now that your mutual bodily contact has been broken. But after a brief pause she pulls it up a few inches, looking down between her still widely spread legs. You know where she's looking, but you're already crouching toward the floor. You grab at the carpet blindly searching for a piece of clothing that you may have missed while cleaning. Your finger does manage to grab some loose fabric. You snatch it and begin to rise. But as you ascend and place the fabric on your semi, it dawns on you what you've grabbed when there is so little fabric in your hand. But it's too late. You're committed.

Your sis watches as you rise in front of her holding nothing but a pair of her panties against your cock.

Her instant giggling somehow entices your cock to harden even more. These panties barely offer enough material to cover you right now, let alone a minute from now after additional growth.

"I think I'll go get dressed now," you state, your own cheeks beginning to blush a bit. You back away from your sister heading for the exit. "But your dare has already started, so you're about 30 seconds away from taking a forfeit."

She hops off her desk, still holding onto the front of her dress. "Okay, okay! Then hurry up Ry! You're such a slowpoke!"

"Yeah? Well keep your panties on!"

Bree sticks her tongue out at you and you reciprocate as you stumble your way backwards to her door. Suddenly Bree races toward you. You clutch her panties tighter around your dick with both hands, but she doesn't grab what you initially feared.

"Wait here," she orders, quickly closing the door in your face.

Instantly curious, you of course keep your feet planted firmly on the hallway carpet. After merely a few seconds her door opens again. She peeks around the corner, head, neck and bare shoulder the only thing in view. But that much skin is enough to see that she's already complying with her dare.

"Here's my proof," she says, tossing her yellow dress out into the hallway.

Witnessing the dress she wore only a moment ago sail past you through the air brings your dick to twitch even harder. Why are her panties so damn soft?

"Are you satisfied?" she teases you.

"Just about..." you mutter, shuffling away. "But just think! Spending so much time in your room you're bound to get it nice and tidy!"

"No way! Spending time in here I'll think up an even better dare to get you back!"

"Good luck with that nudie!" you call out, a final insult before stepping into your room and closing your door. Knowing your sis will be stuck in her room naked for the next two days is making your cock swell like crazy. And that thought brings back memories of the day, with images of another teenage nudist flooding your mind. With so much literal and mental stimulation you can't help yourself. You start pumping your cock needily, beating it with intense force and speed. In less than a minute you blow a huge wad into your hand.

...and into your sister's panties.

You shake off the sexual cobwebs and immediately scold yourself for jizzing in Bree's underwear. You didn't do it on purpose. Well, at least not consciously. Maybe you can throw these in the wash tomorrow. You should probably just throw them away. Will she really miss one pair of panties? For now you just stash them under your bed. You can deal with it later.

Pulling on some pants you glance at the time. It's still pretty early. What now?

• Make Bree's dare harder by harassing her

• Kick back and relax until tomorrow
