Hot Summer Job/Bust a nut on these girls
You work your pants and boxers the rest of the way down your legs after you feel the air cool your thighs. The show in front of you is hot enough but it appears that Kylie may have been proven correct; it's especially hot today. And jerking off in your jeans isn't particularly appealing to you. Besides, everyone else is naked...
Larissa's diaphragm expands sharply with each of her drawn out breaths, her control over her body slipping away moment by moment. Slowly, she bends further and further forward, her body curling into a C shape atop her sister. Eventually both of her hands are on the floor, split by Kylie's torso. Her short blonde hair falls far enough forward to obscure most of her face from view. All you can see is her open mouth, panting into the air.
You know exactly what you want. You shuffle forward and reach your non-masturbating hand forward and cup Larissa's chin in your palm. Lifting her head upwards, your gaze meets her penetrating stare. Her eyes are glassy, her expression dreamlike, peering into your soul and staring right through you all at once.
Leaning into her you caress her dainty lips with your own, eliciting a gasp from her and seemingly breaking her sexual trance. Her body stiffens, straightening up and becoming hyper aware. Her mouth jump starts into action, trying to follow the movement of your lips with hers. As you kiss, you swing your knee across Kylie's prone form and plant it on the far side of body, straddling Kylie with her tits directly below your cock.
You slip your hand up Larissa's cheek then back into her hair. You begin to kneed at her scalp, trying to offer her even more intimate stimulation. She certainly doesn't hate it, tilting her head toward your hand, a move which offers you even better alignment with her lips. Gently, you tongue at her mouth, not wanting to throw too much at her all at once. Very quickly she gets more and more animated. She grabs at your bicep, reaches forward to blindly run her fingers down your chest and stomach, just trying to touch you in any way. You reciprocate, your hand dropping from her hair to brush down the length of her arm. You reach lower and find her hip. Running your hand up the side of skinny Rissa's tight little body makes her shiver. Or maybe that one was courtesy of Kylie. It's hard to tell. But when your thumb finds the bumpy surface of a nipple with a tiny stiff nub in the center of it, your cock - which you haven't stopped beating since you freed it - has had enough.
As your cock begins to pulsate, your free hand flies up to Larissa's neck. You start to lean forward, buckling with your orgasm, and posture up on Rissa as you continue to kiss her, tilting her head all the way back. Hungrily and forcefully you gnaw at her lips, your chin shuddering with each rope of jism that fires from your shaft. Larissa's hands grip each side of your head to draw you down onto her even harder. You briefly wonder if this is her first kiss. She sure isn't shy about it if it is. Then again what is there to be shy about while your big sister is eating out your pussy?
You pant and moan into Larissa as she does the same into you. You're still pumping your dick even after you've emptied your load forcing your sensitive member to send sharp jolts of pleasure down your shaft and up your spine.
After a moment of stillness, hovering above Rissa's lips and sharing her still shaky breath, the two of you part to expose the gap between you and allowing you to witness the carnage your cock has wrought.
Larissa's stomach has at least four distinct shots scattered around her belly button. The largest glob has already dribbled its way down her pelvis. The two of you watch as it slides its way down the front of Rissa's slit where Kylie quickly laps it up. The teenager coos approvingly and tilts her chin even higher, pressing her mouth over the full length of Rissa's pussy. The overstimulated girl gasps again and latches onto your shoulders to steady herself.
With what hit Rissa you wonder if Kylie is in the clear. Cocking your head to the side you find just how wrong you are. A thick rope runs the length of Kylie's stretched neck to her collar bone. In addition to that, various smatterings and drops have sprayed out onto her tits spackling her nubile breasts and running along the inside of her scarce cleavage, a small milky pool forming in the center of her chest.
Entirely spent, you roll off to one side and collapse onto the carpet. Kylie is still going at her younger sister's snatch, but Larissa has enough wits about her now to pry the hands off of her thighs and lift herself off of Kylie's face.
Kylie's first words after her lips are free are, "I can't believe you came in my mouth, sissy!"
"Came?" asks Larissa, still hovering above her sibling.
"You had an orgasm!" insists Kylie.
"Actually... I think that was Riley."
"What? But I tasted..."
Kylie pushes past her sister and sits up frantically. The pool of cum on her chest immediately trickles down her front, curious fingers dabbing at the flow. She then glances at her sibling spotting the plentiful streaks over Rissa's stomach and pelvis. Finally she darts her head in your direction, your deflating erection the smoking gun of the whole affair. A look of shock washes over her.
"You... you came in my mouth?"
Kylie sits there letting it all sink in. Literally in regards to your cum. Once she manages to process everything she scrambles to her feet. Stomping around the room grumbling to herself she retrieves her shirt from the floor then, troublingly, your pants, followed by Larissa's nightie. You try to talk to her but she's already streaking up the stairs, the loud slamming of a door on the second level finalizing her exit.
You and Larissa shift your gaze from the staircase to one another. You both casually examine each other, sprawled out naked on the living room carpet.
"Really?" you ask aloud, after running everything through your mind again. "You didn't have an orgasm?"
Rissa shakes her head plainly then looks down between her legs before poking experimentally at her reddened sex with a single digit.
