John is very, thoroughly, recently spent, and so this message to him (long, hot) does not do the same things the last one did. It's very hot to read, though.
The clothespins thing is sad, but if it's true then it's true. He doesn't want to damage her in whatever way leaving clothespins on for a long time does. (What does go wrong? He should probably look it up himself.) Shifts could work, though he really should look it up to understand in more detail.
The temporary copies thing, on the other hand... John really likes that idea. Obviously it's far off (and further off than the non-temporary copies, clearly) though the idea of having someone he could hurt and damage without worrying about the consequences... that definitely is having an effect down below. Even in his current state. (What would he even do with power like that? Besides the clothespins thing. He's having trouble coming up with good ideas, but still knows he wants it.)
Other things having effects on him: her finding and using fucktoy (a term he's most familiar with) and cocksleeve (a term that he probably has run across before but doesn't recall, but the meaning of which is rather clear and extremely hot) as terms to describe herself. He really, really, really likes this, and also everything that comes after in that same paragraph.
(He's also excited about better birth control methods that don't involve a condom. Condoms are supposed to be worse than without, and he wants to enjoy his fucktoy fully and properly.) (There's no way she's going to figure something out before the ritual so he can take her virginity without a condom, is there? Oh well. Maybe he can ask to do it just this once, for well, symbolic reasons? He's probably not going to ask though.)
He writes:
Four going on five after your note, though I don't think we'll get to five. I'm turned on by everything you wrote, but not enough. Keeping a high score seems fine as long as I can try to beat it with you.
He really does want to give her lots of orgasms. Even if doing it when she told him not to last time caused problems (and he still feels awful about that). With permission, though...
Understood about the clothespins thing. It's a pity, but I'll be careful from here on out.
I am very excited about temporary copies now, though I know they're a long way off. And I'm also very excited to call you my fucktoy sometimes, or my cocksleeve, when you're acting like one. They are in fact very fitting terms.
I'm also really glad about the hot things we come up with together! I've never done anything like this before, and I'm glad you're enjoying it so much. And I'm also very much looking forward to you being mine.
