I have never flirted or been flirted by the staff, I always just thought it was off limits.
Honestly I am face down ass up, so even if there was a staff member I wouldn't know... Lol. Although the last time I was at Flex, my room was right near the laundry room. I was just getting ass up when two staffers walked by and I heard one say "Damn". A little bit of time and fun had passed, when a real quiet guy walked in closed the door, pretty much just slide in and pounded for about 15 minutes and dumped 2 loads in me, he was pretty endowed as well. As he finished I looked up and seen a person in all black leaving the room. Didn't think much about it, after a few hours I was packing up to go and walking out of the room when a staff member walked by, smiled and said that was a great break time.
