"F-favourite dildo."

.....You don't actually have a favourite, of course! B-because you don't really have one at all!{if SexToy == 1} Well, there was Alex, but he was less of a dildo and more of a friend.{endif} You just had to think quickly, and it seems like it's something that she wouldn't go to other staff members about, since it'd be embarrassing for you and she seems like a pretty good teacher. Plus, it's something that rolls! So it makes sense that it might not be right by your desk. Actually, given the short timeframe and requirements, you're pretty proud of yourself for coming up with this one! N-nearly.

"Oh." Professor Phoebe pauses to think for a moment. "Well, I suppose that that could roll around, so let's at least check under the other desks."

See?! Justification!

The two of you take a bit of time looking under each of the classroom's desks, but since there are only six, it doesn't really take that long. Professor Phoebe straightens up to check under her main table-desk right at the front of the classroom, and you follow along behind.

You might've gotten too into character. You're here to try make her cum, you're not actually trying to find something -- and talking about an imaginary dildo doesn't make it appear in your hands! You're not sure how good of an opening you'll get when she's looking through her desk, but you need to jump for it. The second you see anything at all that resembles a chance, you have to go try and take it, or you might as well not have brought her here!
