Compensate Kate for her work.

Alex was in awe at her new body. As she ran her hands over her incredible curves, she turned to look at Kate, only to see that the pervert had started masturbating. "I think I know exactly how I want you to repay me for this..." Kate said with a wink. Alex, having had done this to woo Tina, was questioning herself over whether or not she wanted her first time as a futa to be with a different woman. But seeing Kate with her shirt lifted up and her pants down just low enough that she could get to her pussy made Alex decide that polyamory would be the way to go. "Well, let's do it then..." Alex said in her new, sultry voice.

Kate tied her shirt so that it would continue to reveal her breasts and midriff and walked over to Alex, swaying her relatively wide hips in an exaggerated way as she did. She then pulled Alex into a very passionate kiss, slipping her the tongue almost immediately. They made out for several minutes, Alex pressing her huge tits against Kate's average-sized pair all the while, until Kate finally pulled away. "Your lips are so full! I wonder what they would feel like against my other lips?~" Kate said with a giggle, "But I think there's something we'd both like more than you eating me out..." she continued, rubbing the tip of Alex's futa cock against her soaked pussy. Then Alex braced Kate against a nearby wall and easily slid her huge cock into Kate's wet cunt. The two of them moaned in ecstasy as the new succubus penetrated her proverbial mother.

They fucked for nearly an hour until they came, Alex pulling out to finish in Kate's mouth. "You know Kate, if you don't count masturbation, that was my first time." Alex said. "I bet it was amazing. It was for me..." Kate replied. "It was indeed. That was enough sexual energy for me to conceal your more... hellish features for a few days. Would you like me to do so now?" the voice in Alex's head said. Just as Alex thought 'yes' her horns, wings and tail disappeared and her hooves became human feet. Then, a thought struck Alex. "Uh, Kate? Did you think far enough ahead to bring me some new clothes?" Alex asked. "Shockingly enough, I did." Kate replied, getting a pair of black yoga pants, a similarly colored tank top and surprisingly a pair of boxers out of the backpack she'd brought with her. The clothes fit Alex quite snugly, being sized for Kate's slender figure. And, feeling quite sexy, she decided to tie a knot in the tank top to show off her flat, toned stomach and tiny waist. Then, the voice in Alex's head spoke again, "If you're wondering how others will react to your transformation, I will make you secrete a pheromone that will cause people to think that you've always been this way." it said.
