Like a good little slut, of course

"I'm so glad I bought you these as a gag gift last year."Sarah giggles as you find yourself blushing, worried about just what you are going to end up dressed in.

The two girls turn towards you with the clothing in their hands, but you're unable to tell exactly what it is. They place the bra around you, positioning it, and while it feels different, you are quickly told to keep your eyes up when you try to look. Once again the order of "Up" is given, but this time its more authorative and you find the panties quickly slipping up your legs. They, too, feel strange...almost as if parts of them are missing, but you find yourself being led towards the mirror once more.

You gasp, shocked at the abrupt change, and stand still. Your eyes wide as you take in the sight of your new sexy body standing in a bra that doesn't cover your nipples and panties that leave your wet pussy bare to anyone who walked in.

Your sister Gwen approaches, her hands trailing across the top of your bra of what you thought was a decorative design, but you quickly realize it was letters. "Suck These" with little arrows pointing down towards the general direction of your nipples, even as Sarah's hands trail across similar letters on your panties. "Eat me" your panties command.

"I...think there's been a mistake..?"You hesitantly ask, trying to cover yourself as your face flames red. Your hands are quickly removed as Sarah sinks to her knees beside you, her hands possessively grasping one of your thighs.

"No mistake, little slut. You've clearly gone too long without affection and, with my brother out right now, it falls to us to be...hospitable. "Your sister replies as she leans in, taking your erect nipple between her lips and begin to suck and nibble. Sarah slides herself around, her blonde hair framing her face as she leans in and begins to lap at your wet pussy.

The two of them begin a mission to please you, but never quite seeming to allow you to cum. Your nipples become fully erect from your sister's teasing, her hands sliding up and down your back with gentle scratches. You press your hips against Sarah's face, but she simply pulls back, leaving you gasping, begging to be allowed to cum.

"Don't be silly, slut. We both know there's only one real way for you to cum and that's with a nice, big cock in your slutty, wet pussy, isn't it? We can help, if you'd like, but there can't be any complaints..."Gwen replies, cupping your chin in a commanding fashion as she leads you back towards the closet.
