Newton, stretched and looked across the lab. Hermann Gottlieb, or rather the back of him, was visible. The soft noise of his incessant chalking was bizarrely comforting. Hermann was muttering to himself as usual. Did it help him think, or did he just like to grumble? Newton knew the man wouldn't turn around so he stared freely. Hermann's body was thin, but not just thin, what was that word? Lithe. Yeah, definitely. Though he used a cane and his walk was awkward, the way he slid up and down the ladder as he worked was graceful. In fact, every time he caught Hermann moving toward the ladder he almost always stopped what he was doing to watch him maneuver on it. Presently, he was just standing, staring at an equation, a hand on the back of his attractively scrawny neck. Newton gulped. He could just imagine, gripping him by the scruff of that close-shaven neck, lightly shoving him backwards into the chalkboard, kissing the life out of him...

"Newton," Hermann said, distressed. Newton could feel every letter as he spoke, taste his own name on Hermann's lips. He felt lightheaded with sated desire. "You're ruining my equations," the man said into his mouth.

"Nope! I took a picture, see?" Newton reached into his back pocket and held up his phone. I totally guarantee he thinks I'd be inconsiderate and mess up his fricken equations. But they mean so much to him, how could I do that? Hermann looked at Newton tenderly, uttering his name again in gratitude, sighed with pleasure, and kissed him full on the mouth, daring to add a little tongue. He'd be totally classy about that, I'm sure, Newton thought to himself.

"God, you do feel lovely..." Hermann breathed between caresses.

"Wait," Newton stopped, leaning on his arms, hands covered in chalk, "You actually think I'd ruin your equations? All your work?"

"No, I suppose not..." Hermann said, returning to Newton's lips.

"No, seriously?"

"You want reassurance?"

"Yeah." Newton felt himself melting into Hermann. He bent his elbows and pressed Hermann flat against the chalkboard. Oh my God, have I got a praise kink? Hermann was about to reach up to Newton, but he didn't get very far. Newton pressed his chest into Hermann and took hold of his wrists, pinning his hands to the ledge of the chalkboard. A couple pieces of chalk hit the floor, one was ground into powder beneath his boney fingers. Newt imagined Hermann's thin, strong hands, covered in chalk dust. He needed to catch his breath. Wow, this really is a fantasy because Hermann's not saying anything. But I wanted him to now.

"Hermann," he said, still lip to lip, "Say something."

"Like what?" Hermann was breathless too.

"Anything...I just want to feel your mouth."

"Oh, Newton," he said, indolent, drawing out every syllable, "How long have you wanted to do this?"

"Do what, Hermann?" Newton played dumb, not wanting to do the talking.

"Force me...up against the chalkboard...manhandle me...explore my mouth..." Newton moaned deeply...

"Are you alright, Newton?"

"What?!" Newton practically jumped off the floor he was so startled. Hermann had turned around and was looking at him suspiciously.

"You just made...a sound."

"Oh really?" Newton failed spectacularly at pretending to be unaware of the blatantly orgasmic noise that just escaped his open mouth. "Yup, I'm totally fine, just been a long day. Iiii'm gonna go clean up. See you later." Newton turned on his heal before he could see the painfully bewildered look that was no doubt painted on Hermann's face.
