He had a substantial void in his recollections of the evening they met, which, given their professional relationship, was a serious concern of his. He was afraid he may have wandered over the line while sitting next to her at the bar, and she would have something to potentially hold over him. And in fact, she did offer that he became somewhat 'touchy/feely' during their initial meeting that night. It was a playful remark, and he took it that way. But there was also the implied admonition that 'touchy/feely' had no place in their relationship. But he wasn't sure she was serious, or perhaps he just didn't care. Pursuing her was worth the risk.
Other than the initial revelation of her desire to fuck a guy with a strap-on, and his volunteering for the duty, the subject did not come up again. Just as well, for the time being anyway.
He never considered himself to be dom or sub. Nor did being in the immediate proximity of a cock while fucking another man's wife cause him to think about anything other than pounding the pussy in front of him. But, he had enjoyed having a toy in his ass during conventional sex with previous partners. No, that wasn't entirely true. The vibrations of the toy against his sphincter carried right through to his dick, and right into his partners' pussy, causing the most extraordinary, unconventional orgasms either one of them had ever felt!
So he couldn't help but wonder what a nice pair of tits bouncing against his back while being drilled by a strap-on would feel like. To be able to reach back, grab her ass cheeks, pull her in, deep and close.
He had no idea of what the impact of her watching the strap-on pound into his ass would be.
Could she feel the other end of the dildo pounding against her own pussy?
Maybe she needed a jumbo butt plug/vibrator in her own ass so she could share the experience?
He would eventually bring himself to climax, while fingering her clit and bringing her own climax to an explosive end!
But, he would have to wait, as that could never be their first encounter. He would need to prove he could satisfy her pussy, and possibly her ass, before asking her for similar treatment.
However, her intrigue with the size of his dick did persist.
He had only physically touched her once in a sexual manner. A quick, or perhaps not so quick, handful of her right ass cheek during a congratulatory hug after her divorce was final. While she didn't encourage him, neither did she pull away, something she vowed would happen earlier in their relationship during the 'touchy/feely' discussion.
She often remarked about the size of his hands, trying to correlate the size of his dick with the size of his hands. At least now she had a real reference, seeing that old picture, and perhaps fantasizing on riding that beast?
