Hello.

So this chick that i hooked up with lately, texted me from her trip saying:

I'm coming back this week and i would love to meet up at your place on tuesday to study maths for about 3 hours. See ya :*

I helped her already once few months ago and it turned out into very amusing studying and in the end us ending in bed + she got a really good mark on her test
Last week I also helped her with some ideas on her essay. (we didnt meet just wrote her some ideas with 0 effort because i had time at that moment).

Now she knows I'm very good student, but I'm wondering if I should agree on this text, because I do not want to become her on - call teacher that she can ''abuse''. So i was wondering to reply that i am pretty busy on that particular time, but we can meet up for a drink later in the evening. What do you guys think?

To handle out even the inception of this misconception, lol rythmic words, just set up a small hoop for her to jump in order to avail your help.
As the joker in The Dark Knight says -- "If you are good at something, dont do it for freee..!! "
Your idea of suggesting a different time to meet up shall also work fine.
Another alternative if you want to meet up and not postpone, could be to text her something funny like --

"Sure, as long as you dont piss me off... and hey dont forget to bring that giant peacock feather to fan me out. !! "

She would know it to be a playful banter and also should project not-an-on-call-teacher vibe a little.
