Lust and jealousy in Beldri and Nyla's home

As evening approaches, the crowds of the Prominence Festival market fair begin to filter home via the park. With their private spot becoming less private by the moment, Beldri invites Rexus back to her family’s home.

They walk arm-in-arm, mostly because the elven girl can barely stand on her own. The first, second, and third orgasms of her life have left her somewhat unsteady, but Rex’s larger human frame provides plenty of support.

As the pair enter the cozy, two-story cottage where Beldri’s family lives, they come face-to-face with Nyla. Rex’s classmate (and Beldri’s little sister) is sitting by the fire, wrapped in a blanket and reading from a tome that was assigned to them as homework.

“Um... Hello,” the petite girl says, practically hiding behind the large book. Her eyes dart from Rex’s face to his crotch, then to her sister’s dazed expression, then to the moisture dripping down her leg, then back to Rex’s crotch. “I... I didn’t know that you two were... That you knew each other.”

“I wouldn’t say we really know each other... Not yet,” Rex replies casually, helping Beldri inside and shutting the door.

The moment the older girl has her shoes off, she hurries toward the stairs. “Are Mother and Father home?”

“Not yet, they’re still at the—”

“Good,” Beldri replies, then looks a little embarassed. “Um, we’ll be upstairs. Rexus is going to help me study.”

“B-but you’re a year ahead—” Nyla stops short, still trying not to look at the bulge forming between the human boy’s legs. “...But... I suppose Rexus is very advanced, isn’t he...”

“Isn’t he just?” She turns to Rex. “Shall we?”

As he follows Beldri up the stairs, Rex flashes Nyla a warm smile that makes her squirm beneath the blanket. She’s so very focused on his handsome features that she doesn’t notice her sister tearing off her clothes; Beldri is nude before she reaches the top of the steps.

What Nyla does notice is the sudden squeal as Rex sweeps the older girl off her feet. He carries her into the bedroom, and once that door slams shut they aren't seen again for nearly three hours...

...But they certainly are heard, if only by Nyla. The moans, thuds, and slaps upstairs drive the normally-shy elven girl further and further into a warm, fuzzy, lust-fueled delirium. Within minutes she's touching herself beneath the blanket, her book cast aside. Then she moves to the stairs in order to hear better, still working her fingers into her tight pussy as she perches on the steps. But each of her sister's blissful moans is more intriguing than the last, and soon the stairs don't feel close enough to the action.

Before she knows it, Nyla finds herself leaning against the wall just next to Beldri's bedroom. Her hand moves frantically now, thumb gliding across her clit and fingers struggling to reach deeper... To make her feel what Rexus Aldrin's long, thick human cock made her feel. Her eyes close, and she lets her head fall back against the wall.

Through the thin wood, she can feel every shake and shudder as the bed slams against it. Over and over, harder and harder... And through those vibrations, she feels Rex's every thrust... Almost as if she's the one who's on the bed, beneath his perfect body, legs spread wide, his huge member deep inside--

"Aaaah! Oh Gods, oooh..."

Nyla almost blacks out as the wave of pleasure hits her. The moment of pure ecstasy is followed by one of terror, as she realizes how loudly she moaned. Thankfully, her sister is even louder, and the thrusts continue.

The rutting couple keep at it for a while longer, while Nyla goes on a turbulent and cyclical mental voyage just outside. Her first state is nervous embarrassment:

I shouldn't be listening, I shouldn't be here... Oh Gods, what if Mom and Dad come home?

Which is immediately followed by rising jealousy and anger:

Why her? Why not me? He already HAD me, yes, but wasn't I good enough? How dare they flaunt their pleasure, in my own home?

Which soon gives way to pure lust:

I can practically see him... The sweat on his beautiful brow, the look on his face as he fills her with... Oh, Gods...

And then she touches herself, **** for another orgasm... Which she finds, again and again, more quickly than she thought possible.

The cycle repeats itself six or seven times, with long periods of half-conscious dozing between. It's in one of those sleepy periods that the thumping finally stops, the house falling silent. Nyla doesn't hear the steps approach, nor does she hear the creak of the door.

She wakes to find Rex standing over her. His half-hard cock is hanging just a few feet away, dripping with cum and her sister's juices... His slightly-muscled chest is bare... And handsome-yet-alien human face is beaming with a kind smile.

"Hello again, Nyla," he says. "Have we been excluding you?"

"Y-yes," the girl murmurs. She realizes she's still clutching the blanket, and throws it aside; the last thing she needs right now is to protect her modesty.

"I'm sorry about that. How can we--"

"Take me," she blurts out. "Right now. I want to feel your cock again."

Rex's smile grows wider as he joins her on the floor... But he doesn't grant her request. Not right away, at any rate. First he gets her soaking wet, his fingers and tongue doing as much as she accomplished in half an hour on her own. Then and only then does he claim her pussy, pushing his cockhead past her lips before working the entire shaft inside. He goes slowly and gently at first, until Nyla wraps her legs around him and begs for more.

Once they begin rutting in earnest, it's Beldri who feels the wall behind her shake. Confused, she peeks out--Only to find that the man who just left to "get some water" is now balls-deep in her little sister.

"I th-think I'm in love with you," Nyla moans, running a hand down Rex's back.

"I--" Rex is about to reply, but he hesitates as an image of Teysa Vandis flashes through his mind. "...I'm g-gonna cum," he finishes, thrusting faster.

"Gods yes, please, inside me--Oooh!"

She tightens around his pulsing shaft, her own climax helping to squeeze an impossibly large load out of Rex. Without thinking he leans forward and kisses her deeply, their tongues dancing as their orgasms subside.

"What the hell are you doing out here?" Beldri is standing in the doorway, her naked body dripping with sweat and Rex's seed.

"S-Sis! I--We--"

"Come inside." The older girl is grinning, now, and she reaches out to help them up. "It's not fair to leave either of us out... And the bed is much more comfortable."

The door closes, and doesn't open again until the girls' parents return home late that night. And though the sisters have some difficulty with equal sharing of Rex's attention (and his cock), jealousy is the last thing on their minds as the three of them tumble beneath the sheets.

By the time the human boy hops out the window and walks off into the night, they feel closer than ever... And completely, utterly exhausted.
