"You're only allowed to watch"

"Imagine he comes to you one day and says 'My cousin Nikki is in town this weekend. You know, the one I have... a real crush on.'" It's still odd for her to say that out loud. She's still getting used to the fact that you've always had a thing for her.

Katie nods, rubbing herself slowly.

Nikki goes on. Her voice is drenched in naughtiness. "And he says 'She's agreed to give me the best blow job of my life. And she wants you to watch.'"

Katie smiles as she rubs. Sure, this whole situation is ridiculously silly. But she's having no trouble getting into it.

"'and only watch'" Nikki adds.

Katie's eyes open. Her face is painted with an uncertain expression. She's not sure if she just wants to watch. This is a new turn of events for her.

"'You can touch yourself, but you can't touch us."' Nikki goes on. And you're not sure if she's saying this in the fantasy as if you're saying to Katie, or if she's really genuinely saying it right now. "You have to watch your man with the girl he's crushed on longer than anyone. And there's nothing you can do but appreciate the show. And it's all he's ever wanted. Would you approve?"

Katie shoots you a look, and takes a deep breath. Just like you, she's not sure if Nikki is indulging in a fantasy or being serious. But at this point you're not sure if it's any use being difficult or disagreeable. You see Katie trying to channel her dirtiest self. You love watching her eyes as you know dirty thoughts float through her mind. Her right hand works into her wet panties fervently. Her left hand gropes her own wet breast.

"Well?" Nikki says eagerly, water dripping from her pale body.

You shake your head. You still can't believe this is happening.
