Ask to hypersexualize Stacy

You are instantly hard as your mind races through infinite possibilities, each more arousing than the last. "I want her really well-endowed," you tell Leta. "And I mean everywhere. Tits, ass, cock, the whole thing. You know Mariana Cordoba? I'm thinking like that body, but with Stacy's looks."

Leta grins lecherously and drops her grandiose manner. "Ooh, I like the way you think. So, she'd end up looking sort of like a prettier Sophie Dee with a matching dick?" You nod eagerly. "Nice. Just so you know," she warns, "she might have some little personality changes. More aggressive, more sexual, that kind of thing."

That sounds just fine to you. Although..."Actually, that reminds me," you say. "What if she's mad at me?"

"Oh, I wouldn't worry about that too much," replies Leta. "She might be grouchy when she first wakes up, but everybody loves the transformation eventually. That's part of the deal. She'll be thanking you in no time, trust me."

"Okay," you press excitedly, "How do we do this?"

"Well, we'll need some of your semen and some of mine. We can deliver it however you want."
