Takes photos of her wearing it.

"Ok, let's take some photos," Abbey said. "Maybe it will incentivise them to do even better."

George moaned as Abbey started to strip. "You want to incentivise them to do better?" he asked.

Abbey paused halfway through stripping, "As in I want to see them do well," she said, "not, necessarily, to see them do me well."

George just smiled for a moment. "So, it looks like they are going to hit the top mark and get to play with your tits," he said. Abbey nodded as she pulled on the long jacket George had bought. "I think you should give some more options at tighter intervals. After all, you can't expect the whole class to get 100%."

Abbey laughed as she buttoned up the jacket and adjusted her tits, "So, what are you thinking?" she asked.

"Right now? How much I want a blowjob from you while wearing that outfit," he said. "But as far as points are concerned. So right now, they are 20 points up. At a passing grade, they are playing with your tits. You saw my list the other day," he reached behind his back and took it out of his pocket.

"You think I should tell them that at 60%, I will stop my pill?" she demanded.

He leaned in and kissed her, "Actually, I moved some things about," he said. "So, at 50%, cease the pill and teach naked, here."

"George!" Abbey exclaimed, "If I'm naked here, they are all going to try and cop a feel," she felt flush at the thought.

"I know, and at 60%, I think you should give them blowjobs; I was going to go with tit fucks, but that would be a lot of cum covering you. 65%, the highest scorer gets to date you."

Abbey laughed, "You mean go out?" George shrugged. "You mean the highest scorer would be my boyfriend for the rest of the term?"

He nodded and heard Abbey moan, "70%, you date them all. 75% gangbangs. 80%, you'll be their tutor for next semester."

"You are suggesting that I date and fuck my student bareback and unprotected and let them gang fuck me?" she asked.

George stepped forward and slid his hands into her jacket to squeeze her tits. "Why not? You seem to be enjoying yourself."

Abbey moaned at his touch, "I can't believe I am even considering this," she said. "Ok, but you know they are close to getting me to stop my pill, and it takes a few months for the effects to wear off. But, if the next test they pass that mark, I'm going to be fertile by the end of the semester?"

"I know, and that's why we have a graduation party at your most fertile, with all of your virile students getting to fuck you, bare and fertile," George whispered the words into her ear, and she felt her legs go weak as she shuddered. "Did you just orgasm?" he asked her.

"Maybe," Abbey confessed, "And next semester, reset the score and work their way up again?"

George laughed, "Wouldn't work; they know the game now, don't they?"

"So you suggest that if they do really well, I will be their gang-bang slut next semester?"

"While helping them learn, yes."
