With her talking about this older guy as often as you say she is, it wouldn’t surprise me if it’s gone further than just flirting. And obviously she’s interested in him or she would have politely turned off the flirting by just saying thank for your interest but I’m married.. but it sounds as if she wants it to continue. And your wife giving him YOUR phone number, it sounds as if he is at least admirable by wanting to ask you for approval to go out with her.. again, if they haven’t already met up.. Has she been getting home later than normal.. or telling you she is working overtime.
Yes, I could be very wrong but just from what I’ve read, it sounds as if she is very interested in this guy and she’s not holding back because she’s married. If they haven’t already, she wants it to go a lot further than the flirting and it’s not just for the tips he’s giving her. He’s looking to give her another big tip.. the tip of his big black cock in her married white push..with or without your approval..
That’s what I think anyway snd hope I didn’t offend you in any way..
