Jen's face was hot and sweaty from her first male orgasm. She took her seat in class, taking a few extra minutes to adjust her cock and balls so that they weren't pinned uncomfortably to the chair. Susan was behind her, giggling as Jen shifted awkwardly against the chair.
And what was worse, the first class of the day was something horrendously boring. There was nothing to distract Jen from the stirring in her cock. After Susan jerked her off, Jen assumed that would satisfy herself for the rest of the day. But she found herself hornier than ever. Her mind kept replaying vile images. Things like horses having sex, or Jen having sex with horses. Susan with a gaping horse cunt, and Jen fucking her. Or perhaps a horse fucking Jen.
She was only vaguely aware of how hard she'd become, and that her penis was spurting pre from its slit. Since she wasn't wearing any underwear, all of it went straight to the floor. There was a white puddle forming under Jen's desk. She had slipped a hand down, lost in her thoughts, to stroke her horse meat. Susan was watching, and she too grew a bit wet at the sight of her friend getting aroused.
"Jennifer Smith!!" Her teacher, Ms. Parks, suddenly barked at her. Jen was jolted out of her trance, and jumped straight out of her chair. The entire class snickered, while Jen turned a bright red.
"Are you alright Ms. Smith? You seem quite preoccupied. I hope my lesson isn't boring you." Ms. Parks said.
"Uh, no ma'am."
"Ugh, you just can't control yourself can you?" the teacher said disgusted. Jen followed her eyes down, and saw the mess in her skirt, and on the floor. Embarrassed even though her classmates thought there was nothing wrong with her masturbating during class, Jen ran from the room crying.
Ms. Parks shouted after her, but Jen wasn't listening. Her cock and balls slapped against her legs and she ran. Not caring where she was going, Jen ran out of the school and down the street. Cars honked their horns at her, so Jen fled back to her house, where she hoped she's get some privacy.
Having sprinted home, Jen nearly collapsed on her back porch. Her chest heaved up and down, and her cock and balls were sore because they kept smacking against her legs and getting pinched as she ran. But Jen didn't care. As far as she was concerned, she was just some weird freak of nature. And all because of that stupid Kyle.
"I'm going to kill him the first change I get." she thought angrily, looking around for the spare key her family kept at the backdoor. No one was home, all the cars were gone from the driveway. Jen slipped inside, glad to have the house to herself so she could deal with her problem.
She dragged herself up the stairs, and cried on her bed. Her penis was squished under her body, forcing Jen to roll over. It tented in her skirt, disgusted Jen at how easily it was brought to an erection.
"What am I going to do?" she thought somberly.
Suddenly there was a rapping sound at her window. Jen froze, unsure if she should look to see who it was.
