The world has a 50/50 split of Futanari and regular women, Males do not exist. Futanari are women who have a penis, though they themselves can be split into two genders, Pure and Hybrid.

For contributors As was stated at the top: while there were will be two general threads to go off of (for a guy and girl), feel free to create your own characters or scenarios. The only shared premise among them needs to be that they find themselves, however you decide that happens, in this universe and, as The Eagles would say, "You can check out any t...

Tuesday and Wednesday soon passed. Two days since Carmen wrote Mary's name in the book and transformed her, entirely out of a desire for revenge. A desire that was left unsated. Mary hadn't changed in the slightest, not in any way that Carmen could discern. She remained as narcissistic and hateful as ever, tormenting anyone and everyone who crossed her path....

Carmen glanced back around the corner, watching Zoey leave the short redhead of Gretchen's group. Rachel, if she recalled. They were of equivocal height, though the tanned girl still retained a couple of inches on her friend. How long would that last? She resumed her path to the classroom, doubtful that she could help more than she already had, not without t...

It was maelstrom of fleeting thoughts. Zoey cycled through them all, one after the other, each as unsustainable as the last. She was glad to be with Carmen, though that meant being stowed under her desk for the meantime, but Gretchen was out there. Stalking the halls. Her heels had probably cracked under the force of her steps. Had the black eye set in yet?...

"She's avoiding me," Carmen said, sipping at her coffee. She was sat in Stacy's office once more, both taking their slight reprieve from the first rush of the day, though neither could afford to take long. In the last week, the flood of customers had worsened, as had their insistence that Carmen be front and centre. Stacy had said business on Carmen's off-da...

The wait exasperated everything. Carmen's sharp and heavy breaths, the thudding of her heartbeat in places she wished it wasn't, and the rush of air on her skin all seemed too focused. She listened to the clamour of customers outside, footsteps passing to and from the door, always alert for the dreaded knock. And yet, in spite of that anxiety, her cock stood...

"Thanks, Mary. Honestly, I don't know how it happened," Carmen said, taking the large box from her former antagonist. The blonde shrugged, sending ripples through her impressive bust, which forced Carmen's eyes away. It was getting harder to ignore such things, more so with Mary proudly showing off her chest. The shirt even had the cup-size embroidered into...

I woke up early and was standing at the front window, staring out at the street, when Kim wandered out of the bedroom. "You're up early," she cooed from behind me. "Yeah, the driver said he was going to be here at seven." The sky was just beginning to show the colors of dawn. The horizon was an almost majestic purple. "It's six fifteen," Kim slipped her...
