In High School the hottest teacher we had was a guy named Mr Jones who taught Gym. A lot of girls liked to go and watch the boys training just to see him in shorts. I used to sit there with soaking wet panties before heading off to the girls room for relief. Those big, thick, hairy thighs were in my minds eye quite often when I whacked off!
Also, he was obviously pretty large and never wore a jock, so it used to flop about quite a bit! The girls used to talk about that with a lot of pleasure. One of the girls claimed that a senior from a few years ago named Marcy had jerked him off in his office, 'and it was like a foot long and it spurted two feet in the air'. No-one else had ever met this 'Marcy', it was pretty obvious it was something that she'd thought up when masturbating and so we teased her: 'yeah, spare us your whack off fantasies, slut!'. Still, I bet I wasn't the only one that made use of it for the same purpose!
