Gym class with Ms. Stone and his bully, Jessica

Duncan's mind was in a fog as he walked toward his class, with each female classmate and faculty member he passed making the long dark beast in his pants swell. Girls that Duncan had never given a second thought before today were popping into his head, his now raging libido imagining them in various states of undress and seductive poses. He passed a Latina girl and felt the bulge in his pants pulse as his gaze followed her thick bouncy backside. Catching himself staring at her ripe, squeezable ass, he quickly glanced to the tiled floor as he continued on his way. 'Damn,' he thought as he tried to keep his eyes directed toward his shoes, 'It's like my cock is affecting my mind! It must be pumping extra testosterone into my system or something.'

He looked up from the floor and saw that he had reached the doors to the locker rooms, with the men's on the left and the women's on the right and the gym teachers' office located between them. Normally there were two gym teachers but the senior instructor, Mr Gibbets, had been out the last two weeks on leave after injuring his back during a class. That left Miss Stone, and the last thing that Duncan wanted right now was to have to spend any time talking to the young gym teacher.

Miss Stone was only twenty-four and a former all star athlete at the high school. The complete opposite of the balding, pot-bellied, fifty-four year old Mr Gibbets, the young blond was still just as fit as she'd been in high school. She kept a strict exercise regimen, leaving her body toned and lean, besides her generously curved ass and chest. She had a plump set of D-cup breasts, but she was the only girl that Duncan had ever seen in real life that visibly defined abs. Her biceps were probably bigger than Duncan's and more than once, she'd called him out in class for being so scrawny, telling him that he should spend more time in the gym.

If he wanted to be excused from gym class, he'd have to go through Miss Stone. He didn't know if there was an excuse that he could make-up that she'd believe and he definitely didn't want to explain his new situation to her. An image came to him of the blond teacher's surprised face as he pulled his massive cockmeat from his gym shorts and he grinned, thinking, 'She'd never call me scrawny again after that!' His cock pulsed in his pants again, seemingly encouraging the fantasy, but he shook his head. "Right. And then she'd have me kicked out of school, or worse! That kind of stuff only happens in pornos!"

Duncan glanced again at the doors in front of him and debated what he should do.

What does Duncan do next?

* Try to go to gym class while keeping his new endowment a secret?

* Explain his dilemma to Ms. Stone?

* Go to see the school nurse instead?

*or something else?
