Kinky Minded Swimming Coach

When I was in university, I had to do 2 semesters of sports and I had the chance to do swimming at the campus swimming pool. We've had a sexy female coach in her 40s... and lots of hot young guys and girls. In my fantasy she is bisexual and one day she tells us to do laps for an hour, then we can go home. Meanwhile, she gets into her office and connects to the swimming pool cameras, spying on us as we are swimming. While she is doing that, her mind wanders off, and she imagines herself, ordering us out from the pool, standing in a line, so she can suck our cocks and lick our pussies one by one down the line... Then the whole scene erupts into a wild, bisexual orgy next to the pool (or in the sauna at the swimming pool).
