You and yourself

A muffled cry to your right shifts your attention back on Kim. Your sister is supporting herself against the wall, one hand between her legs and one hand stroking her nipples, turning Tina's sweet face into an erotic guise. You're astonished by her reaction, as if she's feasting with Tina's sorrow. You wonder if it's Kim's soul, Tina's body, or their interaction that gets her that horny, since she can barely stand.

That leaves you. It's your body, after all. It's not that it would be your first time beating that meat. It will be just like the other times. You cautiously approach your sister, and the swaying of two weights on your chest, the rubbing of two wet mounds between your legs, the sticky hair on your cheeks, they all remind you that no, it's not like the other times, it's completely different, it's your little sister the one that you would jerk off with a pair of hands that cannot be yours.

-Tom...- Your broken voice utters your name.

-Hey.- You pipe out with, trying to sound reassuring.

-I'll... I'll do that for you.-.

You sit on the bed, your hand brushing momentarily on its sheets. You slowly move your eyes on her bare feet, her hairy legs, her... dick, her chest, her face. Your face. Oh Jesus, this is so strange.

-Wow... I really look big from here...- You joke, snatching a half-smile from her. You then lean on a little, your manicured fingers getting closer and closer to your old cock. Both your gazes are transfixed on it, waiting for you to tear the veil of abeyance. As your middle finger finally touches it, Tina's member has a twitch that makes you retract in a gasp.

Oh shit, it's normal, it's normal right? It does this every time, so why are you feeling this, this agitated, this scared, this... this powerless?

It's a guy's dick. I have to wank a guy.

Your digits finally wrap your member. It's warm, pulsing. Large, yes, larger than you remember. But it must be your hands. Your feminine, small hands.

You start stroking it back and forth, sloppy noises coming from under its spongy skin. Your heart is hard beating in your chest, but it's like your fear is becoming superseded by something else, something better.

Lust.

Oh God. It's so big.

It's weird feeling the familiar consistency of your penis being jerked but not the sensation of having it stroked. Instead, you feel more liquid hotness spreading between your legs, like million of ants coming out of their hill. But you don't know if you're doing good, you don't know if it's working. You look up to search for your sister's face, but when you meet it she grunts painfully, and you feel the member in your hand becoming even harder.

Oh shit, oh shit, you lower your gaze again, it's working, alright it's working. Behind you, you're distracted by the sound of Kim moaning louder and of her body hitting the wall in a spasm. This is enough for precum to finally leak out.

"I, I usually don't last this long. Tina must be freaking out." You think.

"She's getting aroused by her own body. By her sister. And I am... I am her sister now. I could be the one fingering myself on the wall. Twerking my boobs while she watches. Exploring my... my womanly body.".

Kim manages to pad her howls, but Tina is starting to brace hers. Panic assails you as you recall your mother's complaint of before. You instinctively plug her mouth with your free hand, feeling your own beard and humid lips pressing on your palm. Tina widens her eyes in shock, and as if she has taken it as an invite you feel your hand vibrating against the growing strength of her screams.

"Sh...Shut up, they'll hear us!" You want to say, but as you open your mouth you're silenced by a squeal, a shriek so sharp and lustful that your swollen nipples shiver on the top of your bosom.

Was that Kim? You try to beg her to be quiet, but once again you hear that cry.

Oh God.

It's not Kim.

It's you.

"I'm producing such lewd noises... I'm so horny...".

Your next sound is muffled by Tina's hand planted on your lips, and compared to yours it's so wide that its fingers almost reach your ears. You feel so frail, so little, at the mercy of her superior body. But also... so safe.

"Is this what a woman feels when... uhh!!!" Your thoughts are abruptly cut at Tina's grasping your left breast, which proceeds to massage with vigor. Your Kim's body then reacts automatically, before you can control it, if you would have. One second you're still jerking his cock, the next one you've lifted yourself over it and you're aligning it with your dripping pussy. There's a quick exchange of looks with Tina, time stops for a moment, and then you lower down.

"!!!".

You're penetrated deeply, stabbed between your legs, but instead of pain you feel a burst of pleasure of incomparable quantity. Your inner muscles desperately try to fit around that extraneous, throbbing piece of meat that is diving in deeply. Rationally, you know that you should feel disgusted, if not horrified, by having a dick inside of you.

Instead, you feel like you're dying for the bliss. You rise up again, enough for its fungal head to tingle your labia, and then ruthlessly go back down, this time savoring its sliding in like a breadstick with the butter. You lose awareness of everything around you, fully entranced in your incessant vertical movement, which kills and revives you at every thrust, until all the energy that has been accumulated between your belly and your vagina finally erupts in a wild flood of squirting, at which your body tenses up and your eyes rolls behind their sockets.

"OH GOOOOD!!! I'M CUMMING!!!".

Then, while your mind is still going hectic, something pushes back, like shots of warm liquid filling your urethra. You quiver like electrified by a lighthing, gasping against thick sausages, and then all your strengths fade away. You collapse forward, falling into something stiff and hot, and also hairy. As virile gasps blow on your ears, you realize that it's your body.

And then, you realize something that manages to make you laugh, even in your distraught state.

You've fulfilled your dream of fucking your sister.

Someway.
