Someone is using it on David's wife at the restaurant

The murmur of voices and clinking of glasses flowed around David and Sandra as they sipped their wine and chatted about their weeks. The two of them had been married for several years now, and David could still not believe that he had landed this woman. Thirty-three years old, blonde hair, and a bombshell body, Sandra turned more heads when they were out in public than any woman he had ever been with. While some men might have been intimidated by this, David thought it was hot. He had ultimately married Sandra for her fun and exciting personality, but that didn’t mean that he would ever stop thinking about that body of hers.

She wore a tight and short navy dress tonight, the thin fabric clinging to her hips and dipping low enough to warrant glances from the waiter every time he leaned in with a bottle. Sandra’s laugh was a bright, physical thing, her hands always in motion, her eyes crinkling at the corners. Whenever they were out like this, she always had a sort of mischievous energy about her. Like she knew the attention she was getting and was unafraid to lean into it.

David watched her tuck a loose strand of hair behind her ear, and then lean forward, blue eyes glistening. She was talking about her boss’s new obsession with “team-building,” her hands flitting through the air, her smile edged with mischief.

“…and then, of course nobody actually wanted to schedule the meeting so -ooh!” Sandra seemed to momentarily twitch in her seat as her eyes widened suddenly. She blinked twice then quickly shook her head with a little laugh. "Excuse me! I think there was some sort of static or something in this chair."

David let out a little laugh, and watched his wife eagerly go back into her story. However, she only got out a few more sentences before something seemed to overcome her again.

"So Jennifer was of course really annoyed, so she-nnnhah..."

Sandra's eyes fluttered and she arched her back slightly in her seat as she pressed her thighs together beneath the tablecloth. Her hands momentarily gripped the edge of the table before she managed to recover from whatever had just passed over her. She took a short shuddering breath before giving David a quick apologetic grin.

"Wow! Sorry!" She let out an almost nervous sounding giggle as she shook her head. "There must be something about this wine!"

She licked her lips as a flush creeped into her cheeks. Her eyes momentarily darted around the restaurant as if she was searching for someone but was unable to find them.

“Right…”

David’s eyes flicked up and down as he studied his wife. If he didn't know better, he would say this his wife was getting very horny. In fact, it almost looked like she had just...orgasmed?

Sandra let out a shaky breath, and her hand dropped to her thigh beneath the table, fingers bunching in the fabric of her dress. She tried to continue her story, but this time as soon as she opened her mouth, her voice faltered entirely. She let out a little moaning gasp that was barely audible to David above the din of conversation around them as she arched up in her seat with a small shudder. David caught the way her nipples pressed hard against the thin navy fabric, their outline suddenly impossible to miss despite the bra she wore beneath as if some unseen **** were teasing them directly through the dress.

"Sandra?" David asked slowly, eyeing the way his wife was squirming in her seat.

David had no idea what was happening to her, but it was clear that something was...stimulating his wife. The was she blushed, shuddered, and writhed was making it clear to him. She was clearly putting up a valiant effort to maintain her composure, but it appeared to be a losing battle.

Sandra bit down on her lower lip, closing her eyes for a second too long. Her legs squirmed together under the tablecloth as she crossed and then uncrossed them. David swore he saw the faintest ripple move through her body—a barely suppressed tremor—before she straightened again, her chest rising and falling with hurried breaths. A blush spread across her cheeks as she tried valiantly to pick up the thread of conversation, but failed miserably.

“I—uhh—I’m sorry,” Sandra’s lips parted as though she wanted to say more, but then another invisible bolt seemed to ripple through her body. Her shoulders tensed; her hands clutched at the napkin in her lap. Her eyes darted, unfocused for a heartbeat before she stifled a gasp that trembled on her tongue. Her back arched ever so slightly, pushing her breasts forward so they caught every last stray glance in the room as her ass ground in restless circles against the seat cushion.

David’s concern warred uneasily with his arousal. Seeing Sandra hot bothered like this was turning him on, but what the hell was causing it?! He reached across the table and squeezed Sandra’s hand gently.

“Are you alright?” he whispered.

“I don’t know what’s happening,” She breathed with an incredulous laugh , eyes wide as saucers as a little smile twitched at her lips. "I think - oh god - I think somebody is doing this!" She hissed with another disbelieving giggle as her eyes darted around the restaurant.

She squeezed his hand suddenly on the table as her body momentarily tensed. Her eyes fluttered back in her head and she absentmindedly rolled her tongue across her top lip. David heard the little stuttered moan she tried unsuccessfully to swallow as her back arched again—a subtle motion, but unmistakable. Something was definitely happening to his wife, something deliberate.

“Bathroom,” she rasped suddenly, releasing his hand and standing quickly enough that her chair scraped against the floor. She steadied herself on the table, fingers trembling as they curled around the wooden edge.

He watched her walk away, her hips swaying almost involuntarily, tension rippling up through her thighs and into those curves he knew by heart. The dress hugged every line of her ass and the swing of it drew more than one glance from nearby tables.

What the hell was going on?
