She left her boyfriend Marcus and the rest of the crowd watching the demonstration in the guillotine gallery, turned a corner, and then another, and found herself lured by some warm, inviting light into an empty chamber. A handsome French window afforded a fine view of the city’s outskirts, but even better, the room held a comfy-looking chair. With only a moment’s hesitation, Pia sat on the dark, crushed-velvet cushioning.

It felt good.

So good.

She took a deep breath. A moment later, she kicked off her sandals.

A moment after that, she drew her little black dress over her head.

For a minute or two, she managed to sit quietly, luxuriating in the warm, glowing light on her thighs and breasts, but the tease of the chair’s crushed velvet on her bare bottom, on the delicate petals of her moist sex, became too much: she had to touch.

Stealthily her palm smoothed along her little belly. Carefully her hand wove its way through the soft thicket of pubic puff. Gently her middle finger crept toward the erect clitoris.

She touched the tingling tip of it. Instantly she gushed. The orgasm was as sharp and powerful as any she’d ever experienced. Spasm after spasm of ecstasy ricocheted through her body, leaving her limp, breathless, but also strangely refreshed.

She got up out of the chair and stepped to the window. She stretched. Pia had never felt quite so good.

And then a sound behind her. She whirled. It was Marcus. “What are you doing here?” she asked sharply. In one hand he held her little black dress, in the other a pretty ankle bracelet of turquoise pearls.

“I might ask you the same question,” he said, his voice gruff, his eyes going from her nakedness to the chair and back to her nakedness. He handed her the anklet and pointed to the chair. Right in the center of the plush red velvet seat was a sizeable wet spot. “Is that what I think it is?” he asked, more than a touch of sternness in his voice.

“I don’t know,” Pia answered. “What do you think it is?”

Marcus frowned. “Well, how did it get there?”

Pia managed not to blush. “If you take off your pants, I’ll show you.”

Marcus took off his pants.

Pia showed him.

Her fingers circled his sizeable erection. She drew the soft skin slowly back, exposing the plum-colored cock-head. Precum gleamed in the little slit. Pia slid her hand forward and then back again. His penis was warm. The feel of the skin reminded her of the feel of the red velvet on her ass. Two or three more strokes and his orgasm began. The rich ribbons of ejaculate jetted through afternoon sunlight. The initial spurt cleared the chair; subsequent shots spattered thickly upon the velvet seat as well as on Pia’s little black dress.

“So much!” Pia exclaimed, after seven or eight strong jolts. She licked her lips and milked out a last droplet. “How long do you think before it sinks in?”

Marcus chuckled. He told her he had something else for her from the gift shop— something to match the ankle bracelet, and a moment later fished the present from his trouser pocket.

Pia took the two eggs to the window so the light could play upon them.

“They’re heavy,” she said. “They’re beautiful. What are they for?”

Marcus paused a moment before explaining. “One’s for your front, and one’s for you back.”

Pia grinned at him. “You mean my cunt and my asshole?”

“Yes, your cunt and your asshole,” Marcus agreed. “They have strong magnets to help keep them in.”

“Oh, can I try them now? Will you put them in for me?”

Pia sat in the red velvet chair and lifted her legs over the chair’s arms. Marcus pushed one of the eggs into her asshole and inserted the other into her cunt.

“How do they feel?” he asked.

Pia couldn’t answer. She was already coming.

By the time she and Marcus were waiting in the taxi line, she’d had half a dozen more orgasms.

And long before she and Marcus got home that evening, the boys in security had edited the high definition video from the museum’s surveillance cameras. “Third time this week,” one said to the other. “One more will be the record. I don’t know what it is about that red chair.” They shrugged and smiled at each other and updated the private downloads section of the members’ gift catalog.
