Premature (futa/f, futa-solo, premature ejaculation, excessive cum, teacher/student)

Hi all. Long-time lurker, first-time poster. I wrote this story for AdultFanfiction a couple years ago and decided to bring it here. Hope you enjoy it.

To most observers, Jennifer (called “Jenn” by her friends) was an ordinary girl. An American girl of Southeast Asian descent, Jenn had light brown skin, large brown eyes, a bright smile, and beautiful black hair that fell to the middle of her back. Her large D-cup breasts and pert, round buttocks made her very popular with her male classmates. And she faced many of the same problems as ordinary girls: boys, school, parents, and, as an eighteen year old high school senior, college applications. But as she awoke one Monday morning, she had a problem most girls didn’t have to deal with: morning wood.

Along with a vagina, Jenn had a ten inch cock that was so thick she couldn’t get her fingers to meet around it when it was hard. Her meat was complemented by a pair of balls the size of plums. It could deliver a massive load of cum only to harden less than a minute later, ready to deliver another equally huge wad of cum. Her package would have been the envy of all the boys at her school if any of them had known about it. But the monster dangling between Jenn’s thighs caused her nothing but trouble. It seemed to have a mind of its own. Incredibly sensitive, her cock would harden at the most inconvenient times, such as in school. But that wasn’t the worst part. Because her body produced semen so quickly, it had a powerful urge to expel it quickly too. Jenn was a premature ejaculator.

Once, while admiring her English teacher’s bosom in class, Jenn had soaked the back of the chair in front of her. Luckily, people were too focused on a test to notice. From that day on, Jenn sat in the back of her classrooms. It was a miracle that she had been able to conceal such a big secret for four years at her high school.

So as Jenn awoke Monday morning, her dick was already hard and on the edge of orgasm. “God dammit,” Jenn groaned as she felt the familiar pleasure in her shaft. Resigned to yet another huge, messy climax, Jenn threw off her covers, placed both her dainty hands on her abnormally large shaft and began stroking rapidly. Her huge tits wobbled as she mercilessly attacked her rebellious cock. Her thoughts drifted to one of her favorite jack-off fantasies, a young black waitress she’d seen in a restaurant. This beautiful woman had been five months pregnant, wearing a tight black shirt that emphasized her swelling belly and showed off her caramel cleavage. Jenn imagined herself standing in the restaurant as the waitress knelt before her, somehow fitting her thick cock into her mouth. No woman would be able to deep throat Jenn in real life, but so w
