Politely leave.

Readjusting your trousers, you try to ignore your raging erection. You try to ignore a lot of things. But after this, you'll break her heart and her dignity if you just run out. You need to play this smart.

You place the hand on hers and smile.

"I'm sorry, Allisa. You're so beautiful, but I'm going through a lot right now. I was just dumped recently and I need some time, you know? But I might just have to talk to you privately again sometime. This has been a nice evening. I just don't want to go that far."

At first, you expect her to become furious, or cry, or something. But she smiles. Whatever you said made her strangely happy, though embarrassed. Her cheeks flush red as she tucks her breasts back into her top.

"S-Sorry... I got ahead of myself. Please don't think bad of me."

"I don't. I meant what I said."

"Don't be a stranger, all right?"

"I won't, Allisa." You chuckle and stands up, albeit awkwardly. "I'll head out for now. I'm exhausted and I have things to do tomorrow. Don't feel weird about this."

"I won't. As long as you don't tell anybody."

"I promise. Good night, Allisa."

"Good night, John."

You make your way out the door after waving goodbye, and as the door shuts behind you, you breath a huge sigh of relief. That was close. Too close. You had no idea your teacher would take her breasts out for you, and it seemed like she was willing to do a lot more than that. You try not to flood your mind with lewd thoughts like that right now and you walk to your car.

You make your way home.
