Does Max add any new rules to it?

Yes, about nudity

Max entered Tom's classroom with sandwiches again. The other man looked up from his desk and smiled. Tom crossed room and gave him a kiss as he grabbed the bags from his hands.

"You have the best timing in the world, I'm starving."

Max chuckled and set the drinks and his bag down. "Only for you." The other man blushed, started clearing his desk, then wrapped Max in a hug and gave him another kiss.

As they ate together, they chatted and joked around. "I could never be a biology teacher. I'm too squeamish," Tom said. Max rolled his eyes. "We don't do nearly as many dissections as college kids do. You'd be fine."

"What about your anatomy class?" Tom countered. "I'd rather explain trig than all the gross stuff bodies produce."

"I don't know why you've got a problem with saliva since you don't seem to mind sharing yours with me," Max growled, leaning in for a kiss. Tom met him halfway and gave him a peck. "That's different."

"How so?"

Tom blushed, "You turn me on."

Max chuckled. "In that case, can I count on you to be my model for male anatomy in a few weeks?"

Tom turned his head away. "I can't get naked at school! Even if it was for educational purposes, I'd be fired so fast."

Max put his hand on Tom's thigh. "I'm sure they could make an exception for you."

Tom's face got redder as he sputtered, then got up to use the bathroom.

Max laughed to himself for a moment, then stopped. He suddenly remembered the nude photos Tom's ex had been passing around. He wondered if Tom's reaction hadn't been shyness so much as fear. Max thought for a moment, then pulled out the book.

NEW RULE: Tom and Max can't be fired or receive disciplinary action for being naked on school grounds.

Max put the book away feeling proud of himself and the plan he had. If all went well, he'd be seeing Tom's naked body soon.
