Hot Summer Job/Exercise your new found power while you masturbate
Bree gives you a giddy-bashful smile when you start slowly pumping your hand up and down the shaft of your freed cock. Her incredulous grin seems to prove just how amazed and interested she is seeing all of this first hand, even if it's with her sibling. You can only imagine what weird and exaggerated stories she may have heard at her sleepovers. But all of this means you likely have a lot of leeway when it comes to exercising your newly acquired "powers" over your sister. She may have agreed to take your forfeit, but she's still doing all of this voluntarily. Even with the right incentive it's hard to know just how far you can push your little sister.
You drop your hand to the side leaving your erection to bob freely in front of you. "Lay down," you order.
Bree's giddy expression quickly disappears. That wasn't a dare. With trepidation she asks, "Why?"
"Your forfeit. You have to let me touch you anywhere." You reach out to softly tuck a strand of hair away from her face. "And if my sister is going to make me jerk off for her - and without porn, too - I at least want to have a little fun to get you back for it." As if jerking off is such a hardship.
Bree's grin returning, she appears to consider this conundrum she's in. She stares longingly at your exposed stiffy. For a moment you worry she might be contemplating letting you out of her dare.
"Just touching, right?" she asks warily.
You nod. "That's what I said. I mean, I guess you don't have to lay down, I was just trying to make it easier for you. And for me."
Bree puts on a mockingly dramatic voice, tossing her short hair with playful attitude. "Ugh. Fine."
"On the table," you instruct before she can finish turning toward the couch. Bree corrects her trajectory, quickly sits down and splays out on her back over the hard surface. You grip your dick and start up a slow pump again, walking around the coffee table almost menacingly. Her grin grows wider, flashing her teeth. She watches you with unwavering interest.
Even while you lean down and grope the bare half of your sister's flat chest, you blatantly eye up your sister's crotch, so happy you cut away the fabric between her legs. She follows your gaze and eventually covers up with one hand, your focused stare making her self conscious. That won't do. You drag your fingertips over the short length of her torso then bump your hand into hers to remind her of your new power..
"I'm pretty sure I did say anywhere," you stress again, pushing her hand aside.
Bree shifts uncomfortably. "I know. I was just... itchy."
"Yeah?" You pull apart your sister's legs and kneel down between them. "So am I."
Bree tenses up when you plant your thumb on one side of her lips and plainly open up her sex. You rotate your hand and push the other half of her labia open with your fingers, all the while jerking off as per her dare. Your sister is probably kicking herself now that you're effectively making her do the dare that she refused to do herself, opening up her virgin snatch for everyone in the room to see. It's almost a shame there's no one else here to enjoy the sight.
She lifts herself up onto her elbows so she can look down at what you're doing. Maybe she just wants a better angle of you jacking off. But despite your masturbation you aren't finding much satisfaction. Staring into your little sister's bright pink pussy is making your dick angry. If you could just feel her excited slit against your shaft... You shuffle forward, creeping your way closer until the head of your cock brushes against your sister's lips.
"Wait," squeaks Bree. "You said just touching."
"Yeah. And I want to touch you with my cock. So what?."
"But we're not supposed to do... that," replies Bree coyly. Her cheeks are fully flush. She's getting awful shy all of a sudden for a girl who wanted to watch you jerk off.
"Do what? Have sex?"
Bree actually glances around the room, as if someone might have overheard. "Y-yeah."
You weren't exactly planning on fucking your baby sister. Then again, you're not sure what you were planning to do after rubbing yourself against her. You're not exactly thinking that far ahead. But come to think of it, does Bree even know? She's only 10 after all.
"Do you know what sex is?" you ask with a raised eyebrow.
Bree unconvincingly nods while looking away from you. "Yes. I mean, I think so."
"Okay, then you tell me." You shuffle forward some more then rest the full length of your cock over your sibling's tight little slit. "If we're touching like this, are we having sex?"
Bree peers down at the impossible scene in front of her, her brother's highschool cock placed so purposefully against her grade school cunny. She takes a few seconds to size it up, really evaluate what it is you're both doing..
"Umm... no," she timidly admits.
"Okay. So then touching is fine. What about this?" You pull your pelvis back then thrust upward, rubbing the underside of your cock to and fro across Bree's bald little mound.
"No," she replies following a shudder.
"So both rubbing and touching is okay? Hmm," you contemplate aloud. "Just as long as it isn't sex. But... what if I touch you inside?"
"Inside?" she echos.
"Yeah. Like this."
You reposition your fingers between Bree's legs and double the force you used to spread her vulva a moment ago. This time you push her lips apart as wide as you can. You really stretch your sister open, smoothing out the inner folds of her already featureless underage pussy. A mild whimper the only protest, her tiny visible entrance widens just a bit, glistening in the light. With a steady hand you manage to dip the head of your cock most of the way inside her slick yet unyielding little hole, her tight lips forcing your foreskin back.
"You're... inside," Bree notes breathily, almost as if she didn't know that was possible.
"Yeah, but we're just touching still. We're not having sex, right?"
Bree's head bobs from side to side inquisitively. She studies your partly-joined privates, carefully inspecting the throbbing member that is on the cusp of properly penetrating her.
"No. I guess not."
"Good. Well I guess I should keep jerking off, right?" You ask, gripping your meat. Bree purses her lips together and speedily nods. "Cool. And of course I still get to touch your other places too." You illustrate this point by brushing your palm across the thin monolayer of lycra covering Bree's stomach. She briefly watches your hand meander across the lower half of her body, then focuses lower to get a better look at the raging erection you have begun to service once more.
You're not slowly jerking anymore. Even though you can only access the shaft, you quickly ramp up into a needy, hungry rhythm. You hand bops against Bree's vulva again and again with every upstroke, rapidly tapping her soft parted lips. Along with this, forcefully working your shaft is wiggling the head of your cock just inside your sister. Combined, Bree is having a hard time sitting still. She's constantly shifting and wriggling beneath you, and even briefly paws at the top of her supple mound. It seems you're not the only one enjoying this.
It's somewhat astounding that your sister is allowing your cock part-way up inside her flawless little snatch. Even if it's just the tip, you can hardly believe your sis is actually that naive. Sure she's young, but she's not stupid either. It sure didn't take much to talk her into "not-sex". Either she trusts you implicitly (which has rarely ever been true) or she just wanted an excuse to tell herself it was okay. You sure aren't complaining. Even with just the tip in, her pussy is so velvety soft despite how tight she is. It won't be long before you're painting the walls of your baby sister's vagina with your spunk.
But can you take this even further?
