Happened to me about 12 months ago with a temp at work. We clocked each other when I walked into the office she was working in. Our paths had no reason to cross or indeed any reason to interact with each other. A few of us had a night out in Manchester a couple of months later, whilst she was still with us and she came along too. I spent most of the evening with her and eventually we (deliberately) got separated from the group. No sex, but we did some naughty things down an alleyway in Manchester. Completely different to how it is with a WG.
She continued to work for another couple of months before going back to college. She's 20 years younger than me, fit as fuck, with a body to die for. Why she was interested in me is a mystery. We're going out again next month and she's coming too (a relation works for us) which might be fun, although we may have to use different tactics this time. I may book a hotel so we can do things properly.
Never thought I'd admit properly cheating in public and actually feel ashamed of myself. There you go guys.
