This is a story I've never told anyone, it's going to be nice to actually let it out. So, like the title says, I hooked up with my friends dad and obviously my friend has no idea about it.
A little back story, her father and I would often playfully flirt with one another when nobody else was around, say for example I went to downstairs at her house to get a drink and her dad was there, we might flirt a little, and I would often notice him checking me out, just as I'm sure he noticed me checking him out. This went on for a couple of years until we finally hooked up.
