Sex Education 101 was one of the elective classes at the local University, a class available for all, but usually taken by freshmen to prepare them for the sexcapade that was university life. The class was a legend; easy to pass, easy credits, a sexy teacher, and it was about sex, what was there not to like? There were a limited number of available seats each semester, however, and it was worse than trying to buy a new console on launch day when it came to sign-up day.

Today was the first day of class, and the students were excited to start, so much so that some had drawn and written on the chalkboard in the front of the classroom.

“Good morning class,” said the tigress with a smile as she walked over from the door to the chalkboard in the front of the classroom. The tigress teacher wore a white button-up blouse, an insanely short purple skirt, and matching leg warmers. Her hair was tied up in a ponytail, and she held a large cardboard box in her arms that had a few books stacked up on top of it. She dropped the box and books onto the teacher’s desk in the front of the class of students and smiled at the teenagers and young-adults sitting in their lecture seats and staring at the scantily dressed professor.

“I’m Professor Alex Marx, and I’m going to be your sex education instructor this semester.” Alex turned to the chalkboard and raised her brows as she looked over the drawings and messages. Sperm fertilizing an egg, someone vouching that “horsecock is the best”, and someone’s phone number left alongside a drawn equine member offering free horse dick to anyone who called. Alex let out a soft chuckle and placed her hands on her hips as she turned around to face her students again, “It looks like you guys have some knowledge of the basics already, it’s a good thing I prepared something special for us to work on, today.” The tigress took the textbooks she had on the cardboard box off, set them to the side, and then opened up the box to take a little peek inside.

“A lesson that I think the canine students in the class will appreciate,” she continued and brought her gaze up from whatever was inside the box back to her students. Her green eyes lingered on a few of her male canine students. She noticed that every one of them shift their legs and shook her head just a little before she stuck her hand down in the cardboard box and pulled out the item she had inside it.

Out came a large deep red knotted canine dildo, red from its tip down to the shaft, light purple around the knot, and a darker purple down at its suction cup base.

“Today’s lesson, we’re going to learn how to properly take a knot… And before those of you who don’t like taking knots whine, or those of you who have knots do, this is very important stuff. We’ll also go over how to properly clean and take care of your canine penis…” The students in the class were mostly silent, some were taking out their books or iPads to take notes, while others looked confused. A wolf who sat in the middle row of seats whispered to his dalmatian friend and they both began to giggle, disrupting the classroom and what Miss Marx was saying for a short moment.

“Do you two have anything you would like to share with the class?” Alex looked straight at the two young men with a smile and leaned onto the desk in front of her. The two canine males snickered and chuckled some more, but stopped once they saw that their professor was looking at them.

“Oh, come on. Share with the rest of the class now,” the professor continued, gesturing her head encouragingly. “What was so funny?”

The two canines were reluctant to say anything, but the one who had initiated the whisper to the other mumbled something under his breath.

“I’m sorry, please speak louder so the entire class can hear you.” Alex smiled.

“I said, this will be useful for us to go and tell our girlfriends about, ma’am.” The wolf said rather sheepishly, his ears folding down onto the top of his head. He seemed embarrassed and his friend was silent with a similarly embarrassed expression on his face.
