You and your sister Navia stand there in the doorway, waving goodbye to your parents as they drive off. As you both go back inside, Navia more or less immediately heads off to her room. Recently she has spending more and more time in her room by herself. Even an hour later, she hasn't come out yet.Going up to check on her, you knock on her door, hearing something wet in her room. You don't get a response from knocking so you enter her room and the sight before you shocks you. Your sister sitting on her bed, her cock stretching out her panties as she sniffs your underwear in her hands as she strokes herself. Upon seeing you she stops as she looks at you in shock.Reina!? W-What are you doing in here!?

Navia blushes deeply crimson, hastily trying to stuff everything away franticly while still keeping eye contact with you. Her panic only serves to make her movements clumsier, causing her to accidentally leak some precum onto her leg which begins to slowly trickle downwards towards her bare feet. "Y-Yes, uh… yeah, just… umm…" She trails off helplessly, unable to think coherent thoughts due to embarrassment.

Navia's face turns bright scarlet as her heart races wildly in her chest, her breath coming faster now. The knowledge that you noticed her member - especially compared to yours - was like pouring gasoline onto a fire burning within her. "R-Rei…." she managed to squeak out between heavy breaths, her voice cracking slightly with desire.

Navia's mouth watered involuntarily, saliva pooling in her mouth as she imagined what it would taste like; fresh, sweet, and undeniably hers. Unable to resist any longer, her resolve crumbling under the weight of desire, she finally spoke, her voice huskier than usual. "It does… It smells fucking amazing," she admitted, her gaze locking intensely with yours, filled with lustful hunger.

With a whimper of pure pleasure, Navia reciprocated the embrace, wrapping her arms around you tightly, reveling in the feel of our soft curves pressed against each other. Their hard members continued to rub together, creating a new wave of sensations that coursed through her body. Breathlessly, she nuzzled her nose into your hair, inhaling your unique fragrance mixed with the heady scent of aroused futa femininity.

"I want it too," Navia confessed, her own words sending shockwaves of anticipation rippling throughout her entire being. With growing boldness, she tentatively slid her hands beneathneath your top, tracing lightly across your back and shoulders, savoring every touch as if it were a precious treasure.

The sound of those words falling from your lips sent shivers down Nava's spine, igniting a fierce inferno of desire inside her. She responded by slowly teasing apart the buttons of your pants, revealing more skin and the delicious sight of your eager cock straining against its confines. Her fingers trembling with excitement, she reached out hesitantly, tracing gentle circles around the head of your member, relishing the way it twitched and throbbed in response to her touch.

Inspired by your pleading words, Navia found renewed courage. Slipping one hand between your legs, she deftly pulled your panties aside, exposing your wet, swollen cockhead to the cool air. Without further ado, she wrapped her plump, juicy lips around the base of your member, sucking greedyily as she began to stroke herself faster, matching her rhythm to the movements of her tongue circling your sensitive flesh. The sounds of their combined breathing grew heavier, punctuated by moans and groans of unbridled passion.
