Offline/Tag: Ask your sis what turns her on and give her a proper orgasm
"What gets you horny?" you ask, breaking the brief silence but none of the tension.
"Huh?" She sighs, her clouded expression holding strong.
"Y'know, like, what makes you feel naughty?" As she continues to look down blankly, you brush across her clit at the top of her slit for added emphasis. "When do you feel good? Like, excited. What makes you hot?"
Her cheeks already flush, Emma takes another heavy breath while staring down at her body. "Uhh... getting n-naked."
"Yeah?" As if you didn't notice. "So you like getting naked? Showing off? That gets you horny?"
She nods. "Yeah, I guess, but... I l-like getting Asha naked m-more."
The pace of your penetrating finger increases slightly while your sister's admissions get you harder and harder. "Really? Asha? You like taking her clothes off? Even more than your own?" Emma just nods, forcing you to continue. "What else do you like?"
"Tou-... touching her."
"What? Like her hand?"
"No... Actually, sometimes. But... Her body. I like touching her body. She gets so shy, embarrassed , and.... and when we pe-" She stops herself midsentence, getting noticeably tense before continuing. You're not sure what that's about. Maybe she even got off a little. "That's, um... touching her. Yeah, I like that."
You leave your sister's clit and slide your hand up over her stomach, rubbing around her side then up to her chest, bringing her attention to her own body as well. You circle one of her nipples as you continue your slow steady thrusting with your other hand.
"So you must have felt really turned on, really naughty, when you danced with her last night."
"Mhmm," she nods and whines, like she's more embarrassed to admit to these things than letting her brother sit here and finger her.
"You did. I watched you the whole time. You got so excited getting Asha naked. And when you played with your slime too."
"Her... privates..."
"Yeah, her pussy," you stress, slamming deep before sliding your wet finger out of her just long enough to rub her thick slick juices the length of her slit. Emma keeps taking heavy breaths, her eyes fluttering. "When you played with Asha's pussy... and when you fingered her," you add, pushing back inside of Emma's tight little hole.
"I l-like... y-your fingers."
Yeah, that's hot. You've only been using one, but you immediately shove a second digit into your sister's clenched pussy. "Fucking right you do."
Even though she's squatting, or maybe because of it, her insides are squeezing you so tightly that the additional finger makes it much harder to thrust up into your little sis. You twist your digits, forcefully drilling into your sissy's virgin vagina. After a few seconds of corkscrewing with constant pressure, and Emma starting to squirm, you punch through whatever was holding you back and are suddenly knuckle deep with two fingers inside your younger sibling. Emma jumps and yelps, grabbing your wrist with fright, but you're already thrusting away like before.
"It's okay. Relax. Just relax. You're stupid tight right now."
"That hurt," she complains, pawing at her vulva and clit while allowing you to continue probing her slit.
"Sorry. I couldn't get in all the way. Probably because you're so... horny." Examining your sister, you notice a bit of blood smearing your fingers and dribbling down into your palm. You thought she was just getting wetter when you felt a small gush of liquid. Clearly you were wrong.
"It's not my fault..." she whines, blaming you for her arousal.
"But this feels good, right?" you ask, as much worried about her as hoping to prove a point. Emma gives it a good hard think before biting her lip and reluctantly nodding yes, reinforcing your confidence. "Okay. Then focus on that. Close your eyes and think about everything that gets you excited."
Locking her still cloudy gaze with you for a moment, her eyes shut when she silently agrees. She's giving in to her pleasure and you can see it over her whole body. You grope at your sister, roaming her small figure with one hand while stretching her airtight hole with two steadily thrusting fingers. You give some extra words of encouragement, reminding her of all the things that gets her horny. Emma's breathing quickens and she starts heatedly grabbing and rubbing her flat chest. Little twitches and halting breathes become apparent as her legs get weaker. She's hanging on your every word, her head rolling from one side to the other.
"Jay, I... I need to pee."
"No you don't."
"I do. I... I n-need..."
"Then do it. Do it, Em. Just go."
A few seconds later Emma's eyes flutter open and her hips buck away from the tree. You follow her, thrusting ceaselessly as she whimpers and moans. She then pushes herself off the tree and looks like she wants to get away but you don't let her. You wrap an arm behind her back and pull her in close to you, holding her in place while you finger her even faster. Your little sister lets loose pathetic cries for you to stop and keep going all at once as her thighs clench your nearly vibrating hand, but you refuse to let up while she's still convulsing with pleasure.
This proves to be a grueling experience for both of you. Once you're forced to stop and pull out due to sheer exhaustion Emma outright collapses into your arms all twitchy and spent. You wipe your hand on your shorts, cleaning off the mix of blood and girl cum that you drew out of your sister. You feel a little guilty, but it's clear now what they mean when they say 'pop your cherry'.
Emma is murmuring something under her breath, like some sort of crazy chant or mantra. It takes a moment before you tune in to her mumbled exhales.
"...yourfingers... iloveyourfingers... iloveyourfingers..."
