Hot Summer Job/Be nice to your sister
"You can't beg your way out of this... Don't give me those puppy dog eyes... Okay, okay, mercy, uncle, geez," you finally relent. When she piles on the guilt you can never hold your ground. "Then... take it off as far as you dare."
She smiles widely at you then peers down at her dress. She contemplates her options and starts to lift the dress upward but stops herself, looking uncertain where she could actually stop without taking all of it off. Then inspiration strikes her. She pushes the flimsy straps of her dress off of her shoulders and slips her arms free. It's a very well fitted dress and the top of it barely shifts at all through her movements. She looks up at you with a conniving grin.
"That's not very daring," you critique. "Really, is that as far as you'll go?" It's an almost rhetorical question with your fingers pressed up against her snatch.
Bree rocks back and forth as she mulls over your question. Maybe how horny she is determines her courage? After her cheeks redden some more, she quickly leans back and folds the top of her dress down. Bree lowers it just enough to show off the two bumps on her chest that barely count as breasts. But more intriguingly, her button-sized nipples are pointy and hard, the tiny nubs looking to be rather sensitive.
Her arms outstretched, holding onto your shoulders, your sister presses herself into your hand more forcefully. With her chest exposed she stares into your eyes fiercely, even if you can't seem to return her gaze.
After another moment Bree grunts and throws her hands down, pushing her yellow dress as far down as she can. She slides it well past her belly button, the crumpled top edge dropping to the top of her pelvis, limited by her widely parted legs. The dress still keeps your eyes off of where your hand already is, and keeps her from peeking at you in kind.
"There! I think that's... pretty daring!" Bree declares. Her legs twist around your midsection as one of her hands lightly roams across her taut stomach.
"If you say so!" you counter, although plenty happy to have her go even this far.
Bree scowls at you playfully. "I DO say so! And I also say it's time for your next dare!"
"Fine. Lay it on me."
"Okay... um... you have to close your eyes first." She's looking especially bashful now.
"That doesn't seem like a lot of fun," you shake your head, glancing between her rosy nipples.
"It's my dare! And the first part is you close your eyes!" Bree commands, jumping right back to her playful self.
"Okay, I got it, keep your panties on."
"I'm not wearing any," she emphasizes with another leg squeeze. "So it's kinda hard."
Yeah, well I'm more than 'kinda' hard...
You raise an eyebrow and close your eyes as instructed.
"Wow this dare is tough! I don't know how I'll manage!"
Bree smacks your chest. "We haven't started it yet!"
"Seriously?! I can't even take it!"
"Ry?"
"Yeah?"
"Stop talking."
"Wuh...?"
Your sister's arms slip behind your neck just as her lips meet yours. She pulls her body close to yours and kisses you sweetly with dainty lips and cautious movements. You're taken completely by surprise, barely returning her kiss as you stand naked and frozen in the living room. You open your eyes for a moment, still taking this all in. You note that hers are closed, a strained expression on her face giving you everything that she can. Through her gusto you can tell she's still inexperienced, not that you've made out with a lot of girls yourself.
Bree's breath is shaky, alternating between her nose and her mouth as her lips press into you over and over. She bucks her hips into your hand, perhaps involuntarily, as she loses herself in your embrace. Her passion is infectious, your cock throbbing and pulsating beneath her. Your fingers start up again, circling against the front of her slit, eagerly seeking her clit. She gasps and kisses you harder, closing the tiny gap between you that much further and ensuring that a little bit more of your bodies are making contact.
But you make contact somewhere you weren't expecting. Your throbbing cock pulls up higher and higher until your head taps against the underside of your sis. Your dick touched your little sister's ass. The shock makes your hands clench, pulling a finger right up into Bree's clitoral hood until it pops past it forcefully.
"EEEEP!" Bree yelps, leaning back and breaking your kiss before a shiver runs through her body. That shiver causes her to slump forward into your chest just as fast as she pulled away.
The two of you remain still for a moment, lightly panting in each other's embrace trying to compose yourselves. Bree's slump also managed to lower her body an inch or two bringing the same butt cheek to rest against the tip of your stiffened cock.
"Well..." starts Bree, slowly leaning back under your support. "I'd say that was a good dare. What's next?"
