You woke up Mom again

Pants and sighs reverberate in the room, by now intoxicated by the smell of corporal fluids that have been released by your switched-up bodies. While you're laying upon your own, your now fluent mane spread on its manly chest, your mind is spacing into a cosmos of chaos and wild wondering, unable to process the full entity of the forbidden pleasure you were baring up to a minute ago.

"It's... not... possible..." You think.

"It can't be real...".

A noise, a voice coming from the outside, brings you back from the afterglow. You need several moments to recognize her, and even more to understand the meaning of her words.

-Tina, what's with this noise? Are you ok?-.

"It's only Mom... Mom???" An adrenalinic rush awakens your limbs and you laboriously raise your head in alarm. You look at Kim, who is fatiguely getting up, holding onto the wall.

-Yes, I'm fine!- She answers after some hesitation.

-Are you sure? I'm coming in.- Your skin gets crawling when you see the door handle turn, and Tina too eventually realizes the imminent danger.

-Wait, don't!- Kim shouts, just when the door is beginning to spin.

-Why?- Comes Mom's confused voice from beyond the fissure. Your heart is drumming down your throat, and you instinctively hold your breath. Just another second, another centimeter and she could see you on the bed. The minimum noise, the little cry and you're doomed, she will open the door and it will be over for you.

And Kim knows it too.

-I... I'm not p...presentable...-.

Some moments of intense silence, and then: -Erm, I see. Well sweetie, try to be less noisy next time, ok?-.

Oh shit, by the tone of her voice, she has understood that... holy fucking shit!

-Y-Yes, I'm sorry.- Kim lowers her face, but you can see how it has become even more purple than before.

You hear your mother's steps leaving, and you finally blow out. You realize you're still trembling though, still shaken by terror like you never did before. Why can't you calm down even now that it's all ended? It's because of female estrogens? Is this how girls usually feel like? You're not sure you like this...

A warm arm encircles your waist, and almost immediately you feel melting into a sense of safety and security. However, much to your later embarrassment, Tina was just trying to get you off, as she actually pushes you aside and sits on the bed.

-That was close.- She comments.

-Yes... and it hasn't worked!- Kim scoffs. Then, horror and disgust disfigure her pretty Tina's face.

-What have we done? I just, I just let you have sex in my body! With my brother! Oh my God!-.

-Calm down, it's not that bad...- You try to sound reassuring, but as you stand up you feel something sticky dropping from in between your legs, making you shiver. Kim notices this, and seems on the verge of a heart stroke.

-P-P-Put on something, we have to clean that-that shit.-.

Five minutes later, she is cleaning your pussy with a sponge in the bathroom, wiping vigorously the innermost sides of your folds. The feeling you are experiencing is indescribable, you can't even tell if it's pain or pleasure, if it's tolerable or intolerable, it's like having a caterpillar creeping under your skin which branches electrical sparks all over your body at each crawl.

-Could you be more delicate, please?- You ask with a faint voice.

-Shut up! Just... shut up.- Her tone decreases in an almost begging, something that you didn't expect from her.

Right then, your body joins you. Kim protests against this unwelcomed intrusion, but Tina points out that she's not a real man and that she wants to check on her own body too.

-"We're doing this together", right?-.

Kim's mood worsens even more, and therefore she increases the speed of her rubs.

-We're... almost... done...!-.

You hope so.

-Uh, you're pretty good at this.- You comment in a **** attempt to calm her a bit.

"I guess?".

-Yeah, it's not my fir...- She abruptly stops and pipes up angrily.

-What are you implying???-.

-Nothing, I was just...-.

...Just trying to be nice. Instead you made another mistake.

"Another", that's right. This situation is all your fault: if you hadn't possessed her body in the first instance this would have never happened, and you wouldn't be hiding here from your parents while your sister is cleaning your pussy by your own sperm. In your defense, you've been simply a horny boy who wanted to satisfy his most forbidden desires, and you really didn't want to hurt anyone; but how much can such motivation be worth in the eyes of who have basically been your victims?

-I'm sorry.- You murmur.

-I've been careless and egoistic. You're right to be mad at me.-.

Kim looks in surprise, but she's fast to go back aggressive: -Precisely! This is just because you couldn't hold your dick in your pants! And now... now you've stolen my perfect life and you're going to ruin it!-.

-Hey, don't be so harsh.- Tina comes in your defense, making you blush, another reaction of yours that you can't comprehend. Why are you? It's because it's your sister on the inside, or... or your body on the outside?

-You're right, it's also my fault! I shouldn't have listened to you, I should have done things in my way!-.

-Kim...-.

-Don't!- She shushes you with her finger, turning away from you: -I don't want to hear my voice sounding so weak and pathetic! I just want to go to sleep and wake up tomorrow back in my body! And you two, stay away from me!-.

She strides out, livid and fuming, but you could see the desperation hiding behind her rage. She looked so... miserable. It tears you apart, and you feel your eyes itch.

-Come on, don't worry.- Tina softly says, getting a bit closer: -She will calm down.-.

You nod, but you keep your head low.

-Maybe we should truly sleep on this. I guess I'll take your room, if that's ok for you.-.

-...yes, of course.-.

Tina sighs and opens the door, but you stop her by calling her name.

-What?- She asks, turning around.

...

-Nothing. Good night.-.

-Good night.- She returns. Then, with a sly smirk: -Sister.-.

You smile sadly, and you're left alone in the bathroom. The girl looking back in the mirror is a remorseful and depressed version of your haughty big sister, one that could really benefit from a night of sleep.

-Alright. Things look better in the morning.- You try to convince yourself, and you head back to your sister's room.
