Stay together

You brush your borrowed tits, blushing more in anticipation than by the tepid feeling itself. Nonetheless, you're interrupted by a dreadful glance coming from Tina's (now Kim's) body.

-Get your hands off, dweeb! If you think I will let you alone with my body again, then you're deadly wrong!-.

-But...- You protest. She marches towards you, firmly lowering your wrist.

-You'll do nothing but stay quiet. The only person who will touch my body will be me, understood?-.

You gulp and nod timorously, and so she orders Tina to lay down on the bed. Your original body gives her an annoyed look, but complies and takes off its pants. Your view is however impeded by your shirt, which Kim is unceremoniously discarding.

-Uh, but how will you do if...-.

-Shut up.- She hisses, refraining from screaming just not to alert your parents.

-Just. Shut. Up.-.

You don't think hers is the exact mood for masturbation, but you don't dare to say it. Soon, both you and she are naked, and you're not sure where you're allowed to rest your eyes. You can't avoid taking a peek at the nubile, delectable form of your younger sister's body, at her sinuous hips, her shaved crotch and especially at her plump, rosy tits, still glossy in sweat from before. You feel some radiance down there as you recall the prohibited act you've accidentally assisted to when you opened the door, your little sister playing with her vagina while moaning your older one's name; that is, the body you're currently in: this sexual, breathtaking feminine body, still pulsing from the **** you've committed in its room, a taboo even greater since you didn't just jerk off to your sister, you jerked off as your sister.

Your flow of thoughts is abruptly interrupted when Tina's fingers begin to rub your labia, while her thumb presses and twerks the sensitive lump on their top. Waves of electricity are sent throughout your entire form, making your toes twirl in a spasm and your jaw opening. You barely recognize the resulting moaning voice as your sister's, you have never heard it like this, not even in your dreams; and now, you're the one that is producing it.

-I know all the spots of my body.- Tina's crisp voice informs you, though with your eyes now shut you cannot see her.

-We'll be over soon.-.

Those words strike hard.

"S... soon? But it feels... ohhhh... so good...".

Kim's manicured digits proceed spedly, with surgical precision, depriving you of your breath and your strength. You have to support yourself on her shoulders, but then you feel her free hand groping your chest, where your still extraneous mounds are dangling, and twisting your puffy nipples. Your body tenses all over as if ready to explode.

She's right, you won't last a minute anymore, and this knowledge is excruciating and delightful at the same time.

"My own sister is fingering me... she's fingering... my pussy...".

The contradiction between your ascertained identity (your memories, your inner being, your rationality) and the feeling that your body is instead experiencing intoxicates your mind like myrtle liqueur, spreading a broadening warmth from your stomach. Your closed eyelids light up in white flashes and webs, and you lose awareness of your limbs. Your hands clasp onto something soft and squishy yet with a turgid point, and your knees wobble hectically.

"Oh God!!! I want this to last longer!!! I...".

As if indeed a divinity has listened to your prays, you feel her impetus slowing down, enough to allow your eyes to reopen. Tina's face is right in front of you, red as a tomato, snorting and scrunching her lips. You lower your gaze a little and you understand why. Your fingers are tightly grasping her bosom. That means that those things were...

-Damn... I... you...- Kim's stolen face is contrite in a grimace which you can't discern if it's raging or pleaded. You cautiously move your shaking hands to loosen the pressure, but as you do it she moans and throws herself at you, jamming them between your torsos. Taken aback, you spread your jaw as her fingers resume their work with even more emphasis, her impetus makes you withdraw and finally she buries her face on the side of your slender neck, like an animal assaulting you.

-Ahh! K-Kim! Ahh~~!!-

You eventually find yourself with the back on the wall. The spasms that were setting your groin on fire now thrill you up to the end of your hair. Her fluffy bosom squeezes and pinches the palms of your hands, thereby their backs are scrubbing and mashing yours, the bone entanglement nipping your nipples. Her humid lips chew your skin, leaving circular spots where they suck. You lean your head aside to expose more of your flesh to her untiring hunger, and with narrowed and redden eyes you see your old body furiously stroking its member, couched on your sister's pink sheeted bed, an intruder in their own room. Oh, Jesus, his face, his breath, his heartbeat, you can feel them on your skin! And those big hands, your hands, and that, that cock, that cock that he's jerking on you, because he wants you, he yearns for you, he pines for you!

You clasp your sister's head and shove it more deeply, earning yourself for more, more to feel, more to show. More, just more, endlessly.

-!!!- Your sister retract suddenly, truncating the panache like a cold shower. Yet, in her big blue eyes her burning lust refuses to be suppressed by her frantic panicking.

-No, this is... this is wrong! She's making me feel... toward my body... my own body...! I can't...!-.

She's struggling, fighting inside her mind, torn apart by her instinct and her reason; and it's Tina's face that is suffering, and it hurts your heart to see it like that. But you don't know how to react, how to talk to her, how to touch her, not even if you should; as if you had not a person, but a glowing star in front of you, and you were required to manage it. But your body chooses for you. It takes her by her hands, firstly intertwining your fingers together and then caressing the back of her thighs in a mellifluous movement, and it gently draws you closer to her.

-Let it go, little sis.- You whisper.

-Let it go.-.

With one palm, you trace a line along her hips with its knuckles, reaching up to her cheek and then moving a tuft of hair behind her head. She shivers at your gentle touch and sucks her teeth, eager by herself to remove her own inhibitors, unable to retain herself to wish for more, for again, for you, and so your faces are now getting closer and closer, and your lips are tightening as they protrude towards the other's, and you can already taste the taste of her stolen lips and the fragrance of her nostrils.

-Guys...-

With bated breath, you turn to your sister, now brother, who seems to have called for your help. He's sporting a painful and upset expression on his face, his hands are laying on the side of his hipbones, an anxious tic traveling on their fingers. His, yours, trunk stands by itself, pointing right at you.

-W...What's going on?- You ask. Kim retracts again, an indecipherable mixture of emotions on her face, and she's pending from her mouth.

-I can't do it. I can't... my hands refuse to, to end it. I'm sorry, I... I'm too scared.-.

You open dangling your mouth. Tina is... is scared? But you were too, you remember, when you masturbated for the first time: the feeling of an imminent release, the hormones skyrocketing, the fear of the pornstars' eyes on the video looking at you; it was all so confusing.

And now, your poor little sister is feeling the same.

"Maybe... maybe I could... with these hands...".
