Our wizards inventing magic together is everything.

I would love to see either wizard (Caleb or Essek) creating some kinky magic effect (magic dildo that fucks you until you finish, magic vibrator, magic long distance fleshlight/ magic dildo combo, anything your devious little mind thinks of)

But of course you can't test experimental sex magic alone! So for safety (or fun) they ask the other wizard to help them/make sure they are ok.
