M/26 years old

So I’m still a student to the game, but learning as I go along. Tonight I went to karaoke bar around 10pm. I sang a song and got a number. The chick that gave me her number at the bar was coming down from Jacksonville and she’s 28 years old, but here’s the catch she’s married, yet she gave me her number while she was with her two friends on her birthday weekend. I just want to fuck an older woman that’s older than me by 10-15 years and possibly have a new playmate. I just want to know when is a good time when cougars start showing up at bars.
