[F4M] You can pay your sister back the 2K you owe her. Or put on a pretty dress and go to a Halloween Party with her. Up to you.
I paced back and forth outside your bedroom door. My green boots thumbing on the hardwood as my tits bounced in my leaf-green corset.
I could not believe I was having to do this.
Trust Mia to pull some shit like this. It was so her to cancel last minute. Weeks of planning down the drain as she sent a single text to announce that she's "Gonna go to Ryan's thing instead. Soz. Have fun tho". As if she hadn't been saying how good we were all going to look, just this morning.
It was so. Fucking. Typical.
Jade, of course, was on the verge of a meltdown. She'd spent months prepping for this party. Her first proper college Halloween, her first time hosting, and she'd told everyone that we were going as the "Gotham City Sirens". She hadn't a clue what that actually was of course, but hell would freeze over before she missed a chance to dress as Catwoman.
So here I was. 7pm on a Saturday night, wearing a Poison Ivy costume that left little to the imagination, and utterly without a Harley Quinn.
I took a deep breath as I hyped myself up. Reminding myself that you owed me. Of the 2K I'd given you eighteen months ago and not seen a penny of since. You owed me. You were the same size as Mia, you had to do this. And besides, you were my twin.
You'd say yes. You had to.
Fuck it. I didn't let myself think twice as I knocked rapidly at your door before letting myself in.
I strut right to the centre of your room, ignoring your protests as I toss Mia's Harley Quinn outfit to your bed, dropping my purse to the floor as I turn and glare at you, hand on hip.
"Shut up." I say sternly, "And try that on."

Hey! I'd love to play your older sister as I essentially blackmail you into getting feminised for a party. It'll just be a one time thing... right?
I have so many ideas for how this night would play out, and would love to take you though it in sort of a DM/GM role, having you explore your sister's friend group and get hit on by plenty of guys and girls in the process.
There will, of course, be a bit of incest involved too. But I'm very excited by the idea of you falling deeper and deeper into this lie as the booze starts flowing, the games start coming and kisses start.... kissing?
Maybe some of my friends take a shine to you. In efforts to start paying off your debt, your sister whores you out to her friends.
By the end of your night, my "totally straight" brother isn't going to be so sure anymore. Hell, in a years time, you may have evolved into a full on cum loving trans sister.
Costume's aren't set in stone, I just couldn't think of many trios!
I have a full kinklist but some include:
CNC, cock/BBC worship, feminisation, sissification, bi encouragement, huge cocks, age gap, size difference, interracial/raceplay, degradation, hair-pulling, spanking, slapping, anal, rimming, messy sex, sloppy blowjobs, deepthroat, throatfucking, outfit control, high heels, nails, bimbofication, public sex, light bondage, cheating/cuckolding, dp, gangbangs, groupsex, harems, BNWO, cum
