Proceed with caution

As much as your impulsive side wants to kiss your big sister right here and now, you keep your head on and resist the urge. It’s gonna take more than a weekend of patching your relationship for you to work up to revealing that particular secret.

“I don’t know–” you start, but your sister has already noticed your focus leaving the lap dance to ask yourself whether a kiss is something you’re okay with.

“Sorry! That just slipped out!” she pleads with evident fear in her tone, “I didn’t mean to make things weird. Please don’t be mad.” It seems your parallel thoughts run deeper than being about each other’s lips.

There’s no reason to be scared, but maybe she needs a reminder. “Just ‘cause I said no doesn’t mean I’m mad at you. I meant it when I told you there’s no wrong requests” you explain. A soft smile tugs at your lips. “If anything, I’m glad we’re doing this out in the open. This way you can ask for what you want, and I can set some boundaries.”

Instead of looking relieved, your sister acquires a grimace. She still has a hand in her nethers, but the motions become sloppy and irregular. “Then could you tell me I’m not a monster?” she proposes as her next request.

You set about easing her fears without hesitation. “Hey, no no no, Sis–” You pause the dance completely and cup her cheeks. “Can you look at me? In the eye, I mean.” She answers by meeting your gaze. “Hannah, you are not a monster, and I’m not just saying that because you asked me to. It’s really okay to have the hots for your sister. What you do with that feeling is what counts.”

Her left hand comes up to sandwich your right between it and her cheek, while the other remains down below but without moving. “Thanks, V. Sorry for killing the mood. I can get back to it if you still want me to?”

A playful ribbing should help get the vibes back on track, so you answer with, “Uh, yeah? I expect commitment to the bit.” You slip your hand out of your sister’s embrace and resume touching your chest to egg her on. You keep just your calves together to maintain skin contact.

Hannah resumes rubbing on herself right away. “I’ll give it a shot” she declares, with eyes locked onto your latest exhibition. “If I could have you as my toy…” she nervously begins, “I would put you on display, with multicolored lights.” She pulls her view away from the private show, looking up for validation. You nod for her to continue. “I’d dress you up in tight clothes and break out the professional camera to make a whole set.”

She stops voicing anything other than a fleeting moan, but you can tell she has more ideas bouncing around her head. “And after that?” You try your best to be disarming as you urge her to go on.

The rapid back and forth of pleasuring herself ramps up ahead of her sharing the fantasy behind it. “Once I have enough material to show off my hot sister in my portfolio, then I’d, uh,” she admits with shaky conviction, “strip you down, and take more pictures just for me.” She pauses to catch her breath. “Your slender little body in its uncovered form would be mine to drool over and no one else’s.”

Without you even thinking to prompt it, the riled up bombshell in front of you nudges her panties down with her one dry hand, then shucks her top entirely. “Too hot” is the only explanation she can manage before her vocalization is taken over by increasingly unbridled moans. You follow the visual splendor from her flushed upper chest to her juicy melons, down to where she’s gotten started fingering her wet hole.

The phenomenal show your sister is unwittingly putting on makes you lose your composure, and she doesn’t even realize how she’s affecting you. Her little doll is getting just as much out of knowing it’s doing something forbidden as she is from her desires being welcomed. In your horny delirium, you invite her to ponder, “What’s something you think there’s no way I’d agree to?”

It takes a moment for her to process what you said. “Huh? Oh, I guess anything I saw before? So like undressing in front of me and getting completely naked, or you also touching yourself.”

She’s right about you wanting to remain at least partially clothed. Touching yourself on the other hand, you’re just turned on enough to go for. You step back a little and snake a hand into your shorts, the other tweaking a nipple.

Hannah’s eyes bulge. “Oh fuck!” Her rubbing effort speeds up as she relishes the sight of your dancing fingers. “I was wrong about one.” She latches her free hand onto the ripe fruit of her breast. “Never in a million years did I think my little sister would accept this part of me, let alone offer to present an erotic show. Oh!” She lets out her loudest moan yet, and furrows her brow. You can tell she’s getting close.

The performance deepens in tandem as you mirror her actions. Your pajama shorts provide enough flexibility without needing to displace them. Hoping you still have your own plausible deniability to hide in, you assert that, “I’m just showing you how you look right now, with your wicked cravings put on display.”

Your dirty talk pushes Hannah over the edge. Her legs wrap around yours and pull you closer with a slight stumble. Her glistening fingers end their barrage and simply hold inside. Moans catch in her throat before spilling out all at once.
