"Do you think he wants to fuck me?"
Their dinner guest had just excused himself to make a call and Jo slipped her hand into her lover's and leaned close to him, whispering the words playfully into his ear. They'd had a lovely meal, it was winter again, her favorite season, and tonight she was just... happy. She felt light and sensual, like the microscopic bubbles spiraling in her glass of Crystal, and James looked so handsome in his not-worn-often suit. Fine tailoring always turned her on, he'd been erudite, funny and charming all evening, which was driving her mad, and suddenly she felt a bit giddy and adventurous.
"Why? Do you want him?" James asked dryly, glancing across the crowded room to see if Burton was still out of earshot.
"No, I want you. But I thought maybe we could have some fun. That is if you think he'd be game... and if you're in the mood."
An hour later they were standing together in the living room. James had just lit a fire and it was the only available light, casting a flickering orange glow on Jo's breasts. James was undressing her while Burton watched over the rim of his glass. When she was entirely naked, James urged Burton to come closer, adding "You might want to set that down for a minute."
The bet was entirely Jo's idea. James warned her he didn't think she had that much control yet, but she insisted and promised if she failed, he could concoct a wickedly erotic punishment. But she wouldn't fail.
"I want to show you something," James said, and told Burton to insert two fingers into her cunt. She inhaled sharply at the penetration, they were ice cold from holding his drink. James touched the tip of her nipples, and she shivered slightly as they blossomed. He traced a line up her silken throat, then turned her face to his and kissed her deeply, passionately, pressing her body against his with Burton's arm caught between them. Both men felt her cum instantly. Not once, but repeatedly, over a period of a minute, the whole time her lover's mouth held hers captive. When Burton withdrew his fingers, they glistened with her cum. He tasted it, and murmured he was glad they invited him to the party.
Now that Burton knew with certainty that Jo wasn't frigid, that in fact she was passionate, willing, maybe even easy... James wondered if he'd like to make a little bet, just to make things interesting. He explained that Jo belonged to him and would only cum if he gave her permission. Her lover was willing to bet a hundred dollars that, no matter what he did to her, Burton couldn't make her cum. Until James told her she could.
Burton laughed softly, "No one can do that."
