Love seeing my wife teasing older man

We were on vacation abroad and talking about her wearing sexy, revealing clothes. That night, she wore a thin red dress with no bra, so her nipples were slightly showing.

In the elevator, an older man in her 45-50s got in and stared directly at her chest. She got shy and turned around, but the moment was hot.

Since that day, we share a new fantasy: going to dinner with an older man while she wears sexy, revealing clothes, let him enjoy her, bringing him home, and having him watch her slowly take off her dress while we have fun together. Sometimes more , we fantasize about these kind of things.
Any husbands share similar fantasies, would love to chat , we are 29 yo
