In the end...
You make up
-...you're right.- You finally admit: -I overreacted. I can't tell you what to do with your life.-.
Tina twirls a lock of her morphed hair around her finger: -Yeah, but, it's not fair that I mess up with yours too. So... peace?-.
-I guess.-.
A relieved smile appears on Tina's mouth: -Nice! I've got so many ideas about what we could do together now that we have the same powers! Erhm, whenever you feel more comfortable, of course.- she's evidently forcing herself to suppress all those naughty plans that are turbinating in her mind. It's really sweet of her.
Yes, perhaps your sister may have changed a bit, but she still remains a good person. That's also why you love her.
-Do you ever question if what you're suggesting is ethical?- You furrow. She scoffs: -Oh, come on, I made you fuck Mom, then as Mom, and then Mom again, and now you're concerned for the ethics? It's not like I'm ruining anyone's life... well, except someone who may really deserve it... but anyway, what's wrong with having some fun? Plus, their bodies feel only what we feel: this body,- she grasps her own chest, which you have to remember it's not her real one: -you know, Mom's body, has just experienced pleasure and orgasm. If I edit her memories correctly, she'll never get any trauma, probably she'll never suspect anything is wrong.-.
-Yeah, it looks like you're ignoring many red flags.- You reply scratching your temple: -But I guess it's a way to see it. In any case, uh, what about shapeshifting?-.
-What about? It's crazy! We can turn into other people in a snap! Look at this!- Once again, both her aspect and her clothes change, into another form that is well known to you.
-Ta-dah!- 'Kim' puts her hands on her hips with a satisfied grin. She has chosen a striped shirt-red jeans combo that your elder sister uses sometimes to hang out with her friends.

-And can you impersonate her as well?- You ask. She giggles and then rolls her eyes.
-Like, geez lil bro, you're such a perv, ugh!- She says in her best stuck-up-bitch tone: -So, as I mentioned last night, we can turn into any person, object, or even animal. Damn, big bro, you absolutely have to try to become a dog!-.
You're quite startled by her last affirmation, and so you decide to reply to the previous one: -We can do this even if we're already possessing someone?-.
-Duh! It's even more arousing like this, right?- She gives you a subtle smirk, then she decides to sit next to you.
-And what about possessing someone while already inside someone else? Is it possible too?- You ask, following her motion with your eyes.
'Kim' glares at you: -Oh my gosh, and thank goodness you had ethical concerns! Honestly, I haven't tried it yet. Why don't you try to morph instead? You can do it also in your real body, or outside too.-.
You look down at your opened palm. So, it seems like this manly hand of yours could become the dainty little one of a girl just thinking about it. It's not less mindblowing than being able to hijack other people.
-Maybe later...- You decide to postpone. Your sister seems playfully annoyed by your reticence, but announces that she still has to show you the coolest part of shapeshifting.
-As I was saying, you can become anything or anyone, even something small like a dildo.- You wonder why she mentioned a dildo above everything: -But! You don't have to transform your entire body. For example, you can... make a phone call pretending to be someone else.- you're amazed to hear your Mom's voice leaving Kim's lips.
-Or...- 'Kim' 's head shapeshifts back into Tina's, but the rest of her body remains the same. Since Tina is a bit more tanned than Kim, it's quite strange to notice her skin changing color from the neck up.
-Even a face-call! Mmm, but I guess you'd prefer to see how Mom's boobs would fit Kim's physique.-.
-You're really a teaser, you know?- You dissimulate your growing excitement. The strange hybrid of your mother and sisters chuckles, and then you ask again: -And you said we could become any person?-.
Tina nods, then she has some sort of realization and crawls to the center of your bed: -Oh, and not only some real person...-.
For the fourth, fifth time maybe, her form undergoes a complete transformation; however, this time, the girl she turns into is someone different. A blonde once again, but in some retro style, wearing a red bandana on her hair. Also, she has a nose ring on her nostril, and even if she's not someone you immediately recognize, she looks really familiar.

Your face turns from focused to shocked, as you finally know who are you looking at. It's your mom, only when she was your age!
-Surprise, honey!- Even her voice is your mother's, but younger: -Woah, I don't know if it's the aphrodisiac still running, but Mom's body is really turned on to be this young once again.-.
You're left gaping. This... this was simply incredible. It occurs to you that someone once said, 'your only limit is your imagination'; but she has just made it literal!
-Tina, you... wow...-.
-I know! Mom was really cute when she was 19. Have you ever imagined that she had a nose ring?- You shake your head. Then, your mother's youthful visage tinges with a seductive, erotic charge.
-Say, Tom... what about a second round? No tricks this time, just me, you... and this sexy beatnik body...-.
You glom, seriously tempted by her offer. On one side, you're exhausted, still shaken, and not really lucid; you know you would benefit from some time to process the vast amount of information that has rained down upon you. On the other...
"Fuck. She's really hot.".
What do you decide?
