"Um...can't we just have a proper sexual relationship like every normal couple?"  Tamyshia asked, feeling very embarrassed just thinking it.  "I mean, I haven't even experienced proper sex, let alone lesbian sex and the first time I ever came was when you licked me all over inside your mouth."  She continued, knowing that nobody except Reiko would hear this conversation.  "And besides....I might be only three and a half feet tall when I'm back to normal, but that's still far too big to fit inside your mouth, let alone your belly or intestines.  Also, the protection spell would've worn off by then."  Tamyshia explained in the last five minutes of class.  By now, she had adjusted to the smell, but it still felt embarrassing as she wriggled around in there, trying to get more comfortable since she'd been lying in the same position for a while.
