"Don't you think two sexfriends having a naughty outing sounds so much better than dating"?
...No, not particularly? Dating can still lead to naughty stuff, especially vanilla filled goodness.
That ending though. Well...A theater sounds interesting too. Any chance we get to see it?
What came to mind as the story unfolded is THIS phrase to describe Kaya, which some folks might remember (clears throat):
"She's a Super-Freak, Super-Freak, She's Super-Freaky, Yow!"
Ichi'd better make his mind up regarding whether to maintain this relationship (even as sex friends), as it seems her *cough-cough* "freak factor" is escalating to higher levels.
