You could definitely use some help... But HIM?

You let his offer hang in the air for a bit. Especially the last part. As you are getting dressed, you think things over. He could have fucked you pretty bad - literally and figuratively - if he'd just kept his mouth shut. He chose not to... Then again, he was conspiring with Mandy earlier...

"Why should I trust you?" You ask him once you are fully dressed. "You don't have to. I'd be happy to leave this all behind and leave the two of you to it. I guess... I guess I've just got something to make up for, don't I? So, my help is here if you want it, and I'll be out the door the moment you want me to be. Well, after I get some pants on, that is."

How to turn this to your advantage... Mandy may be an idiot, but even she is not going to be dumb enough to let some guy fuck her while this GAME is on. Not even Sam, most likely, even if she believes he simply failed rather than turned. And she's definitely not going to let him near her ass...

Even just going through the options annoys you, because you know everything you're thinking about her applies to you just as well. You're not going to take any chances anymore. No cum will get anywhere even close to you until this is over. No dicks, even. Fuck, how long is this going to take? Days? Weeks? Months? Knowing that Mandy is in the same celibate boat is only a meager comfort...

Then, an idea strikes you.
