On a 10+, Eva stays after class willingly, and carry +1 forward

The bell rings and the girls file out. Eva is still at her desk, looking your way.

You walk over to her. Her uniform is immaculate, except that her blouse has an extra button undone and she's showing a little cleavage. Nothing like Jessica's complete disregard for the uniform and the deep valley between her breasts. Eva is just being a little naughty, not full-blown slut.

"Well, Eva," you start. "You are one of my best students. I'd like to reward you for the fine work you do here."

"Why, Mr. Ambrose, thank you," she says with a smile.

Luck favors the bold, you hear in your head. So you reach and take her hand, moving it to your crotch. Eva gasps in shock, but doesn't move or pull away. She's looking up at you with a look of awe. You squeeze her hand a bit and rub it on your bulge.

"Oh, Mr. Ambrose, did I do that to you?" Eva says as she lets you rub her hand on your cock.

"Yes, you did, Eva. Now, take it out and lick it," you order her.
