Jennifer and Samantha hurry to class, and first class today is Biology. Currently they are learning about evolution and how different species are related. As Proffesor Wilson arrives, he announces what will be discussed in todays lesson. Today he will be talking about mammals and evolution of feet, with examples such as the horse with its hooves and lions with digits...
Jennifer yawns in boredom. She never liked Biology classes, and the professor is as boring as watching grass grow, though a picture catches her off guard - a picture of a male horse. You can easily see its dick hanging lazily from its body. Though the other students pay no mind, Jenn can't help but fantasize about her walking up the horse, and it putting its huge horsecock in her urethra-pussy. Speaking of which, it is starting to get wet and slick. Red from emberassenent, Jen asks the teacher "Uhm, can I take a second in the bathroom? It's really urgent!". "Okay sure, but you better take care of that *thing* fast,I'm not willing to repeat what I'm saying just for you, Smith!" Snickering can be heard as Jennifer shyly walks to the front through the door. Since everyone can see her half-erect dick and her pussy, it is obvious that the horse pictures arroused her.
As she enters one of the stalls, she hastily strips all her clothes, she is really hot right now. Greedily she takes her now completely erect dick and starts rubbing it against the wall and her big breast, as her equine stench starts filling the room. Her pussy juice flows from her tip, further lubricating her dick and boobs. She starts playing with her balls and nipples while licking her pussy and clitoris. After cumming and flooding the toilet with her semen, she hastily cleans off with some toilet paper and hurries back to class, though she now smells even more like horse. The rest of class passes with nothing special happening.
