After a few minutes of waiting, the door flew open again. In stepped a peculiar woman wearing nothing but some bone jewelry and an eerie oni mask similar to the ones for noh plays. A snake (clearly her familiar) slithered all over her nude body. "Greetingssss, I am Sssaku," she said, her voice very much like the hissing of a snake. "I am the witch who Kyūri hassss hired to change you into formssss better sssuited to hissss heya."
Ellie quickly shifted back into human form, hir fur giving way to bare skin and hir massive cock shriveling back into a clitoris (albeit a large one). She figured it was best to show Saku what she had to work with. She bowed to the masked witch. "Greetings, Saku-sama. As you can see, we werehyenas only have penises in our beast forms. In human shape, we have to settle for clits. This makes us female in our human forms and thus ineligible for sumo training. As for our were fox friend, she doesn't have a penis in either of her forms, and Joelle Bowman's an ordinary human."
"Yessss, I have much work to do," Saku mused, stroking the contours of her mask while her serpentine familiar slithered from her right arm to her left arm. "We will ssstart with getting you your penisssessss."
Saku opened a satchel strapped around her waist. "I have sssix potionssss with me," she said, taking six vials out of the satchel. "I made them jussst thissss morning with fresssh tanuki sssemen. Each of you mussst ssswallow the contentssss of a sssingle vial, and you ssshall have a penissss in each form, human or beassst."
Each girl took a vial from Saku. Beck grinned from ear to ear as they clutched their vial in their hand. "This is it!" the non-binary werehyena cheered. "One swallow of this, and I can keep my dick even in my human form! Best welcome present ever!"
"Jussst one little warning," Saku hissed. "As your new penissss growssss in, you will become exxxtremely arousssed and feel an overpowering urge to masssturbate."
"Sounds fun!" Kristi giggled.
"Well, who wants to drink up first?" Ellie asked her fellow exchange students. She was a bit bashful at the thought that she and her friends might get caught up in a group masturbation session (or even an orgy) in front of their new classmates, but the idea thrilled her just a bit, too. "Who wants the first cock? Who's our first true futanari?"
