Go talk to Emily's other brother, Peter

You slink out of the bathroom carrying your clothes, leaving a stunned James behind you. You don't need to look back to know that he's staring at your ass as you walk out the bathroom door, still completely naked.

You've planted a seed in his mind, telling him about Emily's voyeurism and her interest in his dick. Still, you're not satisfied with just that. There's something inside you telling you to push the Fowler siblings even further, that you can be even more daring and bold. You've never been a shy woman, but this is daring, even for you.

Emily has another little brother. His name is Peter. In all the years you've been friends with Emily, you've had maybe a dozen major interactions with him. There were whispers back in high school that he had a crush on you. Well, why wouldn't he?

Peter's room is at the other end of the hallway. His door is shut, with a scribbled sign on the door telling his siblings to stay out, hastily taped to the door. Somehow, you feel like he won't be too angry about your intrusion. You push the door open without knocking and find exactly what you're looking for.

"Hey," you say cheerily.

Peter is crouched over his laptop at his desk, still wearing a shirt but with his pants around his ankles. He scrambles to cover himself when you enter, only looking more confused when he sees what you're wearing, or rather what you aren't.

You set your clothes down beside the door and close it again behind you. You slink up to him, still seated in his chair, and lean over him. "How are you, Peter?" you whisper.

"Uh," is all the young man is able to manage. He isn't quite as attractive as his sister and brother, with some baby fat on him still, but you remember all the times your panties disappeared while you slept over here and the way he wouldn't meet your eyes in the morning.

You can make your plan happen, and you know Peter isn't going to resist.

"Why don't I help you finish that?" you offer, pointing one dainty finger at his still-hard dick. "And in return, you can help me with a little project I've been working on."

"Uh," Peter stammers. "Anything," he says. "Absolutely."

You smile.
