Only you

You are both astonished for a few seconds. Something suggests you that it is better to close the door for what is coming. The expression of pure lust on your sister's face gives way to anger and embarrassment, as she covers her nudity.

-You! Who the hell are you! Why are you in my body???- She screams with Tina's voice at the top of her lungs. You gulp in awe. Your suspicions were true.

-S-So you're Kim, right?-.

-Yes I am! And I demand my body back!-. Damn, it's strange to see your usually calm little sister behave like this. But it's scary too, knowing who is behind it! Your heart is pounding under your, uh, breasts.

-Who the fuck are you? And what have you done to me???-.

Before you can answer, though, someone knocks heavily on the door. It's your mother, asking your sister why she's screaming. "Tina" doesn't answer for some seconds, then you wink at her and she realizes that now she's the owner of this room.

-Only a nightmare mom!- She answers: -Sorry, go back to sleep!-.

Your mom is relieved, she tells her to slow down and leaves. You wait in silence for her to fall asleep again, with Kim deadly staring at you. You look away. God, your pussy is wet at that furious glance on the top of your sister's pure body.

-I-I'm your... your brother...- You finally babble.

-What? Tom is that you?- She goggles. You nod.

-Oh God, you're a perv!- She shouts, then coughs and remembers to lower her voice: -I'm your sister!- she whispers angrily: -And you, you've done that in my body!-.

-So you remember...- Your voice is trembling as much as your legs.

-No, but I can recognize when my body is excited. Jesus Christ! One second I'm texting and next I'm splatted on the floor with my body hijacked by my own brother! Eugh!-.

-W-Well, you had your fun too.- You point out, prompting her to cover up more with the blankets.

-It's not like that! I went to Tina's room for help and... she was already... doing this. Don't gasp! I don't allow you to be excited in my body, you perv!-.

-Ok, ok, sorry. About what happened, I don't know, I suddenly became a piece of goo. I didn't know you can do that too.-.

-Me neither!- She blurts really annoyed. You flick your long blonde hair nervously, still unable to look at her in the face. What is she thinking of you now? She will be hating you for sure. Oh shit, your life is ruined, she will make it miserable until your last breath!

-Why me though?-.

You raise your head, surprised by her shy tone. You see that she too has diverted her eyes, a cute pout on her face.

-Because... I think that... you're hot.- You spit out, immediately regretting your words. However, her reaction is not the raging one you expected.

-Well... thanks, I guess.- She murmurs, red in the face more than before. You blink a few times.

-You're not angry?-.

-Of course I am! Stupid brother, look where I am now!- She opens her arms, pointing at her current body.

-S-Sorry, you're right. So what do we do now?-.

She curls her mouth and then...
