"So ladies," Amy said as she picked you back up, "What do you all wanna do after school?" She pointed you towards her hotdog and fondled your balls. She stroked your shaft with her thumb, lightly arousing you and getting you erect. You don't think you'll ever get used to just how much stamina you seem to have. It's like you have a very quick refractory period or something.
"We should totally go to the mall," Gloria suggested, peeling a banana, "I wanna check to see if anything new is in stock. You can never have too many yummy outfits!"
"I so agree!" Amy said, stroking you a bit harder, "I could invite Sara over and we could get some more twinsie outfits. Ooh! Maybe some see-thru harem pants! Belly dancer style is so in this season!" She started licking the base of your shaft and an electric current pulsed through your nerves. You blew a huge load all over her hotdog and promptly went limp. "Hee hee! Thank you (Your Name)." She set you down on the middle of the table like you were a condiment bottle.
"If there's any in black," Rachel said, "I'd definitely be interested. Meanwhile, I need to stock up on candles. Full moon's coming up and there's a spell I wanna try. Of course, I'll have to borrow a dick for it."
"Can't you use your daddy for whatever it is, girl?" Gloria asked.
"No," Rachel shook her head, "Mother is going out with him that night. I'll be home alone and I don't have any penis siblings. Amy, you wouldn't mind if I borrowed your brother that night, would you?"
"Depends on what you're up to," Amy replied through bites of her glizzy, "You're not like, gonna kill him, are you?"
"That would be detrimental to what I intend to do," Rachel explained, "I need him alive for the ritual. It's a spell that makes a penis grow as tall as a bimbo. Imagine, a five or six or even seven foot tall cock! The amount of jizz he could make would be nothing short of awe inspiring!"
"Yeah, but like," Gloria asked, "how you gonna fit a dick that big inside you?"
"I could also do a spell of stretchiness," Rachel shrugged, "See if I could fit his entire body up my ass, that'd be hawt."
"I'm sure (Your Name) would love to help you with your magic!" Amy smiled, "Just be sure to turn him back to normal before you give him back. Mom would be livid if he came back home gigantic."
"If you like," Rachel offered Amy, "I could cast a spell of stretchiness on you too, Amy. Or maybe... maybe I could even have you and your brother try that spell together. The Hermaphrodite Transformation spell."
"Her-what-phro-huh?" Gloria asked.
"Hermaphrodite," Rachel explained, "A creature that is both Dick and Bimbo. The complete expression of a human being according to ancient legend. Based on these old-ass cave drawings some sciencey bitches discovered, there's a spell that can fuse a dick to your crotch and make you become one being. Male and female at the same time! Doesn't that sound incredible?"
"I dunno, girl," Gloria sighed, "I can buy making a dick grow gigantic, but that just sounds ridiculous."
"I'll think about it," Amy stroked her chin, "I'd have to get Mom and Sara's approval on it though. If I went through with it, that would mean having my brother all to myself forever. Also, is there a way to reverse it?"
"There's always a reversal spell," Rachel nodded.
The bell rang, and it was time for the next class. Amy scooped you back up into her cleavage and skipped back into the building.
