Meanwhile, Hands Off Frustration in the Bathrooms.

Sarah sat in the bathroom stall with apprehension. Once against she reached between her legs and touched the elastic band of the latex panties, only for them to stiffen tightly against her skin and prevent any purchase. She groaned with frustration as she had all day when she tried to sneak off, every attempt at self-pleasure thwarted by the possessed panties.

Ah ah ah, Honey.

Came that voice that had haunted her all day. Further even. She remembered the voice whispering to her in her dreams last night... She blushed again as she remembered how her dreams seemed to build upon every desire or sexy whim she ever had and... bestowed them upon Adam in her dreams. Her brother was dominated by the rest of the latex collection, twisted into a voluptuous girl, and pleasured ceaselessly by her own toys. Sarah had been constantly brought to the edge in her dreams... only to be denied as her brother got off to every fantasy Sarah ever had for herself.

Oh hun, you agreed to be my little lustful battery, remember?

T-the voice had offered things within her dreams. Power. Magic. Hedonistic pleasures to her heart's content... as long as she was willing to deal with some frustration...

Everything within my power. The succubus repeated the offer she had been given in her dreams. I just need you hot and bothered for awhile, my dear.

She didn't think it was real as she slept! She was flabbergasted at breakfast when her brother matched the latex-clad form he had been twisted to in her dreams. Her confusion had grown even more so as everyone treated Adam as though he was... Aida. A sister doted on by their mom and eyeballed by everyone Sarah had witnessed. Even mentioning Aida to her friends had brought up... indecent comments and probing questions. Sarah had nearly dropped her books when her science partner asked what color her sister's panties were.

Sarah was broken out of her thoughts as her panties began to twitch again, just like they had several times earlier today. They kept bringing her sooo close to the edge, but every time single time she was denied.

“N-not again, please!” She begged out loud.

Don't worry dear. I'll make sure you get everything we agreed to.

It felt like someone was caressing her thighs as the latex panties began to shift before moving into a rhythmically kneading motion. They stretched and distorted themselves like a living organism as she felt a segment squeeze her clit. A tendril of the now slick material suddenly rubbed against her frustrated outer lips before it began to trail downward. She let out a small squeal as it slid against her perineum before she felt it nudging its way between her rear.

It wasn't that sensation that caused her to gasp, but rather a sudden warm moist sensation on her feet and a firm kneading sensation on her shoulders. She looked down but her shoes were untouched and nothing was around her shoulders. It was as if a ghost was massaging her intently.

A glimpse into what your dear brother is feeling, dear.

Even worse was a strange... unnatural sensation within her groin. It felt like the arousal was doubled within her slit, and yet part of it felt... off and strange. A compressed feeling and yet like something that was within her was being massaged... something that didn't exist.

I meant everything your brother is feeling my dear, including his hidden equipment within my snug taut latex package.

She gasped as the feelings abruptly stopped. A slightly uncomfortable feeling within her at the sudden lack of sensation. The succubus's voice suddenly giggled in her mind as the latex panties went still. Sarah couldn't help but try to dig into them at the sudden sexual frustration she felt, but the panties suddenly felt skin-tight and prevented her fingers from digging in.

Hot and bothered honey. You're just going to have to deal with your brother's blue balls for now.

Sarah could only whimper in frustration.

Relax hon. I promise you it will all be worth it in the end... for both of you. Now I need to go tend to Aida's little interruption.
