Susan looked at Jen with a slightly confused face, "You have a flexible penis that you pee with and also use to spray yourself clean, like always."
Jen felt a now familiar sensation between her legs as an incredibly long penis shot out of her body above her vagina. The large penis landed on the floor with an audible plop, and Jen noticed she could feel the floor through it. The thought of having such a thing horrified her.
"How can I have a penis when I'm a girl? I shouldn't have one right?" Jen blurted out frantically, but Susan laughed slightly.
"Come on Jen, you've always had a huge penis and don't pretend like you don't love having it played with!" At that Susan reached down and began to run her hand up and down Jen's penis. Jen suddenly found herself in a state of immense pleasure and began to rapidly pant with her tongue out like a dog. Her penis also began to grow. Despite her building pleasure however, a feeling of terror began to fight for control as she realized what was happening.
"Susan please... in front of everyone...no pe... nis..."
Susan stopped. "Oh that's right you only have a penis so you can't ejaculate or anything, you'll have that erection for a few hours, but at least when you're errect you can reach your penis with your mouth. You're so cute when you're licking yourself."
Again Jen felt her body tingle. Suddenly she had a huge desire to put her penis in her mouth. Hours ago she couldn't imagine herself in such an absurd situation, but it was no longer the past, but the present. And in the present moment Jen began to drool over the prospect of wrapping her tongue around her newly acquired male organ. On all fours she arched her back to bring her penis even closer to her mouth. Her long shaft was now rigidly pointing directly between her hanging breasts which bounced on and off her penis as she began to play with her tip with her tongue.
Jen's actions weren't popular with everyone nearby however. A passing girl commented "Jeez Jen, could you be any louder slobbering all over yourself? Why don't you use that thing of yours like a pacifier and shut up"
Jen's mind went hazy again. She suddenly calmed down and sat on her butt sort of like a dog. Her penis was fully errect and vertical, but now instead of assaulting it with her tongue, she sat with it firmly in her mouth, lightly sucking on it. As before it came with a multitude of mixed feelings. The pleasure of sucking on a penis, the pride of a powerful errection, the embarrassment of pleasuring herself in public, the humiliation of having almost no bodily control, and the horror of having her female body disfigured with male and animal parts. As Jen dealt with all of this the bell rang and she felt a tug on her leash.
"Come on Jen, time for class!" Susan said cheerfully. Jen go back down on all fours, with her legs outstretched as she clumsily walked along unable to remove her penis from her mouth.
