This is a true story from some years back.
I was 19 years old at the time, it was a Friday night, and my parents were out of town for the weekend. I was still living at home while finishing College. I was lucky enough to have a back yard that rivals some of the houses on MTV's Cribs complete with a heated swimming pool, a waterfall and an in ground hot tub.
I threw a small party this night, and we grilled out, swam, drank some alcoholic beverages and had an overall great time like we usually did on weekends. It started to get really late, around 3:30am, and most of the guests had already gone home.
At this point it's just me, my friend Mike, and my friend Tess that are still awake. Mike's younger brother Brian (who happens to have a huge crush on Tess) is asleep inside on the couch in the living room; we can see him through the big glass doors and windows. We've just gotten back in the hot tub for another soak, just drinking and talking as we usually do. We all hang out pretty regularly, but we're all just friends. Until this night nothing sexual had happened between any of us.
