Help. Married man being teased by a busty blond bombshell at work?

I know i'm being a bad boy. I'm a 43yr old married man. I own a business. I usually focus on my business and put all thoughts of pu..y out of my head when i'm there. However, my nether regions are really starting to lead me with a babe i hired. Shes basically 24, blond, tanned, and is galore. Theres a total flirtation between her and I and I'm finding her real hard to ignore! She has the best you could ever see on a woman, they have to be at least an E cup...i know i sound like a right ld perv...but i'm tytt man! Anyhow the weather is scorching here at the moment. Theres a park nearby my office. I wen there for my lunch not knowing she was there....perched against a tree.....her shirt undone......her skirt hitched up...taking the sun. She actually called me over and asked me would i like to join her. She was in her BRA, shirt undone. She said to me 'you dont mind do you'!! I was a sweating larthering wreck...shes clearly coming onto me...what will i do?
