Getting amused at the amusement park

-Daaad, can you stop?- Claire groans from the back seat, right beside your original body. Her voice cuts through the rumble of the engine. Dad's just pulled another sharp maneuver, overtaking a car and swinging back into the lane like he's in a race.

-Sorry, guys, it's a bit difficult, you know.- He says with a sigh that sounds closer to a frustrated moan. You catch sight of Mom sprawled across the front seats, head low, and the wet, rhythmic noises between her and Dad are louder than the tick of the blinker. Tina glances back and nods to Claire.

-Be patient, squirt. We're almost there.-.

Claire mutters something under her breath, probably a complain for how she called her. Tina flashes me a knowing wink. You give her a grin back, but your gaze slips down to her chest. The seatbelt cuts between her breasts, pushing them up under the thin striped crop top. Every time the car rocks, her tits threaten to bounce free. And with Dad's driving, there are a lot of jolts.

-Here we are, gang.- Paul eventually announces as his wife straightens suddenly, wiping a hand across her mouth like she's just finished a snack instead of sucking his cock. The amusement park lights blaze ahead, the music thudding in the air even before you open the doors. Dad pulls into a spot, kills the engine, and you spill out into the night.

-Mom and Dad never bring us out on a school night!- Claire says as you head together for the gates.

-And we still wouldn't, if you hadn't been such good kids.- The phony Marie Anderson answers in that perfect imitation of Mom's voice. After all, under that tone is Michelle Hunt, and thanks to Katie's memories you know that the two matriarchs share the habit to speak to their kids in a gentle scolding. Then she smirks, in a way that isn't Marie's nor Michelle's.

-Besides, we could just call you in sick tomorrow and have some more family time.-.

-I think I like the new Mom and Dad.- David says with a satisfied grin.

-Yeah, me too!- Claire chirps.

The park is a haze of too many bulbs crammed on old rides, stalls reeking of sugar, the air thick enough to **** on. Kids drag parents from one attraction to another, but at this hour it's mostly couples and tight-knit groups of young adults drifting from game stands to rides.

-Alright, here's some cash.- Dad says, handing each of you a five: -The rest is on you. We'll meet you here in an hour.-.

-Nick, you're the eldest brother. Watch over your little siblings and your sister.- Mom says, arm linked with Dad's.

-Try not to lose them while we're gone.-.

-And you two try not to make another one either.- You shoot back. That gets a warm laugh from both of them.

-Well, I can't promise.- Mom says: -Now that I'm officially married to my daughter who's now a hung, it's my duty both as a mother and a wife to handle her new urges. Let's go, dear.- she rests her head on his shoulder, and they wander off together.

You cross your arms, turning at your siblings: -You heard Mom. I'm in charge.-.

-Nu-uh.- Claire shoots back, already jogging away like she's half her age: -She said you had to watch us, which I'm going to make difficult for you. Se you!-.

Your phony self peels away too, mumbling about catching the rollercoasters. You wonder for a second what it's like for him, wearing his old skin, pretending with Katie-as-Tina to be as excited as Claire or Mom. But you know that all the layers under your copied skin make the thrill real.

And then it's just you and Tina. You turn, and your throat tightens. Her seatbelt is gone, but it has been replaced by the strap of her purse pressing across her chest, making the curve of her tits even more obvious.

-Wanna hang out?- She asks, a playful glint in her eyes: -See if there's somewhere private our fam hasn't already taken?-.

-Sure, uh, lead the way.- You say. As you walk together deepen in the park, you notice her way of walking. She struts with her chin high, her hips swaying, knowing exactly what she's doing, and who is staring at her.

-People will get the wrong idea.- You tell her: -If you walk like that next to me, they'll think we're a couple.-.

-And what's wrong with that?- She says, playfully twirling a lock of hair: -I've been a kid for eighteen years, and now I've finally got something to show.-.

She slides her hand over one breast, giving it a slow squeeze: -God, this body, she feels different. Better. I might not give it back when we're done with it.-.

You should be probably disgusted at the way she treats your sister's body like a prop, but the truth is, it just makes you quite horny. And you agree with her: you too feel an extraneous energy running in your veins, and you suppose it's the veins for real, Nick's blood having all the benefits of a body who goes often to the gym. Not a gym-bro, but buffer from the old you (both of them) for sure.

-Hey, look at that.- She says, pointing to the House of Mirrors. Its sign is dark, however. A gruff attendant is locking it up.

-Shame.- She grimaces: -I wanted to try it.-.

-I think I have a key.- You say, pulling the black pen from your pocket. Two minutes later, the door's locked behind us, the man's skin discarded in a heap. Luckily for you, there's a switch right there, which turns on all the lights of the place.

-Let's stick together.- Tina says, grabbing your hand: -Don't want to faceplant into glass.-.

You walk in the preestablished route, from time to time finding yourself at a crossroads, which however reveals the pruning end just after a pair of steps. Your reflections surround you every moment, right, left, even on the roof, showing simply Nick Anderson and his older sister Tina strolling around. It's like they're a testament of your complete ownership on their forms. And while before it was hard not to stare at your sister, now that she's everywhere it's simply impossible.

How her hair falls on her back with delicate jolts when she walks; how her exposed midriff moves like a swaying pendulum; how her tights emerge in rhythm from her pleated, lacy skirt. Your mouth is getting dry. She gives you a side glance with her mascara eyelashes, and then a taunting grin.

We reach the last fork. You start to point right, where you can clearly see the exit, but she heads left without a word.

-Oh, another dead end. My, look at that.- She stops in front of the mirror, swinging back and forth, and then poking her cheeks. Your figure emerges from behind, your hands circling her hips and brushing her flat belly.

-Gym?-.

-Diet.- She says, glancing up. There aren't many centimeters of height difference between the two of you, but they're enough to make this even kinkier.

-Glad you're more… observant tonight. I could feel your eyes on me, you know. So hungry… so scary…-.

You lean down and kiss her, your hand sliding up to squeeze her breast, thumb dipping under her bra line.

-Fuck, I'm so wet.- She moans, her dainty fingers already on your crotch.

-Oh, little bro, maybe I should call you big bro from now. Being outranked by Mom just because I'm female was so humiliating, you know. I wanted to say that I didn't need your defense, but then I looked at you and… and I know I needed your protection. Your touch. I craved for it all the evening. And now…-.

The real Tina would never say that, she would have been jenuinely pissed of being treated like a helpless woman. But then again, she wouldn't unzipping your pants either, which instead she's doing now, grinding her ass back on your groin.

She braces her hands on the mirror, no need to speak anymore. You shove her panties aside and push in.

Her moan echoes off the glass, mixing with the wet slap of your bodies as you start to thrust into her. You grip her hips, watching her expression twisting in the reflection, shifting between groaning to the ground and biting her lip to look up.

-Y-Yes, fuck, I want to see this slut's face begging, o-oh you feel so good, brother~!-.

-We could make it real, what you said before.- You grunt while your shags grow sloppy: -Be a couple in these skins. Disappear somewhere new, where no one knows us.-.

-And get married and have tons of kids.- She breathes: -Mrs… gh… Tina Anderson… hah… grow old together like a lovely couple, going to church on Sunday and, uh, and become friends with the neighbors… and every night, have sex with you, my big brother~~-.

That's enough to bring you over the edge. You empty yourself deep inside her, her body shaking with her own climax, your moans having turned into cries. You sag against the mirror, breathing hard, then pull apart. She kisses you once more, tugging her skirt down and muttering about soaked panties in a very Tina-like way. You remind her whose fault it is.

An hour has passed, as you see on your phone. When you get back, after having returned the attendant to normal, your original body is already waiting, giving the two of you a quiet smile. When she arrives, Claire isn't so discreet, pointing out Tina's still disheveled hair and makeup despite her attempts to fix herself up inside the house.

-Oh god, wait until Mom and Dad see!- She laughs.

-See what, sweetie?- Your mother says, appearing with her husband from behind a corner. You spot a pair of panties stuffed in her purse—definitely hers from earlier. Looks like you weren't the only ones busy.

-You guys used a condom, at least?- David smirks.

-Son, that's not how you talk about your mother's ass!- Dad barks, and you all burst into laughter.

-So, we're going back now?- Claire then asks, all of them looking at you. You had enough fun for the night, sure. But, who says you can't remain there for a bit more? Perhaps switching skins with the rest of them, just to vary a bit. Indeed, after having been a boy for three hours straight, you're quite eager to return to being a girl.

And maybe you know which one you want to try.
