Take over the tour

You decide the best way to proceed is to take over the small tour group, so you activate your mind control ring and approach the guide.

"Hey! Alright, you're done for the day. They need you back in the office. I've got this," you say.

The bespectacled guide looks confused at first, then nods as your mind control kicks in. "The office? Okay," he says, then he leaves in brisk manner.

Next, you introduce yourself to the remaining group of 9 which consists of 3 sets of potential college kids and their parents, and deactivate your magic ring, not wanting to accidentally give out any commands to the unsuspecting group. Luckily, you've been on the tour before and you're still familiar with the campus, so you continue on with it, talking and pointing, making some stuff up along the way although nobody notices. In the meantime, you keep checking out Hannah and it certainly looks like she's lost a lot of that baby fat from before and her body is even primer than before. In fact, you notice, her mother isn't bad looking either with a nice body and you can see the resemblance and how the genes have passed on.

It doesn't take long for the other 2 families to drop out of the tour, wanting to go explore the campus by themselves, and you're left with the 1 family you want.
