"Yes"

You answer with confidence. But Greenie seems dubious. "Okay, because you were just treating me like I was a delicate..."

"Well, I didn't exactly know what you wanted." You have to speak up for yourself, although you don't want this to turn into an argument. You somehow doubt Greenie could get into an argument. And you think to yourself, you do kinda think she's delicate. "You can't blame me."

She smirks. "Yeah, I can't. Okay then, what I want now is for you to slap me as hard as you can." She looks into your eyes and nods.

You nod back. You cock your hand, open palm. You glance over at Katie though the side of your eyes, take a deep breath...

And slap Greenie's left cheek hard. The sound of flesh hitting flesh echoes. Greenie's head fling to the right, her hair flying in every direction, her whole body almost tumbles over, and she has to catch herself on her elbows. Katie gasps.

You do nothing. You wait. You hear Greenie whisper to herself. "holy shit." The she spits and straightens herself up to face you again, running her fingers through her long hair, pushing it back out of her face, revealing a big red mark already formed on her cheek. More tears are sliding down her face.

And she smiles. "Okay. I know you're going to think I'm a crazy person... more than you already do. But I swear that alone almost made me cum."

You're not sure if the same can be said of you, but it has made your cock twitch and throb in new, unexpected ways.

"I have a plan" Greenie says, breathing hard, naked, bruised, in front of you. "I'm going to tell you what I want, so you don't have to worry about that, as long as you do it as hard as you can. Okay? I want you to do it with gusto." This is a thing Greenie says. You assume she borrowed it from some teacher and has since adopted it ironically. When you're watching a movie, eating through popcorn, "damn, we tore through that with gusto." or when she's showing off a new painting. "I really did this section up here with gusto." Now, she asking you to dominate her sexually with "gusto."

"Deal." you say. You have this sense that anything is possible. You feel your brain start to put aside worries, concerns, timidity, naivete. You feel ready to give her whatever she asks for.
