Lara stared at Derrick, swallowing a few mouthfuls of water before coming to a decision. "Alright, Derrick, I suppose you suffered enough-"
"Oh thank you, thank you, thank you-"
"You didn't let me finish," Lara growled, Derrick stiffening up with sudden unease. "I'll restore your body, and even your dick... mostly."
"Wh-what do you mean mostly?" Derrick stammered.
"Well, I'll give you a good five inches. It'll grow over time, but if you ever start cheating again, it'll shrink again. So either stay loyal, or remain uncommitted and you'll keep your man card." With that she snapped her fingers and Derrick bent over, gripping his crotch. Slowly but steadily his vagina filled in as a sack of flesh popped out and his former clit began to grow back, reaching to a good five inches before stopping. He smiled, almost laughing with joy as he realized that he was back to being a male. Just as he was rejoicing his height began to increase and muscle mass returned. Within moments he was at his original stature. I had to admit, she was awfully generous.
Derrick knelt before Lara and thanked her profusely, kissing her hand then feet and essentially worshiping her. "Derrick," she called, looking annoyed, "stop grovelling, it's not a good look for a man."
Solemnly he stood up and looked down at her with abject respect and fear. "Is... is there anything I can do for you?" he asked sheepishly, his cock becoming hard indicating he already had an idea.
"Why yes, Derrick, you can." Lara smiled. Derrick straightened up, feeling the pride he once felt back when he originally fucked her. "I want you to go out there and fuck any woman who will spread her legs for you."
Derrick looked at her, confused, and seeming to wonder if this was an obscure test. "H- how would that be helpful to you?"
"Simple," she said, poking Derrick's chest. He backed up a bit, looking down to see a mark appear on his chest only to glow and vanish before our eyes. "Every time you have sex, I'll get a cut of your sexual energy. With each hookup I become stronger. And Derrick, I love getting stronger. So go fuck like you're about to die tomorrow."
"Y-yes ma'am," he acknowleded, heading towards the door. He gingerly opened it, likely trying to get used to his rejuvenated stature.
"Oh, and Derrick," Lara called, the other looking over his shoulder nervously. "Stay away from Charity. My curse is still in effect, and you've just got another five inches for her to siphon, and I don't do take backs."
"Yes, ma'am," he nodded, leaving the room quietly.
