William J. Moriarty my beloved

First

In which, a naive student believes he has outsmarted his mathematics professor.

⚠️Reader is feminine, William makes out with reader, but it is not too detailed {mainly because author- san is inexperienced 😌}⚠️

I hope you enjoy

"Professor! Professor!" A young blonde raised his hand, trying desperately to catch his professor's attention- who had been carefully writing some equations on the huge blackboard. Said professor, turned from the blackboard with a slightly annoyed look on his face.

"What is so important, mr. Waters, that must interrupt our lesson?" William's voice was strict and so was his tone towards the young student.
Waters flinched, but didn't loose his composure. Gulping, he momentarily remembered a little prayer that his grandmother had taught him, but quickly brushed the irrelevant thoughts off.

"I apologise, mr. Professor, but, I have a... a.. c- complaint!" He managed to stutter out the words he had been repeating on his head since the day before, ignoring Tate, who had been trying to warn him by waving his hands rather animatedly. All the other students gasped.
William let his books on the dark brown desk in front of him and quirked an eyebrow in curiosity (and mild amusement).

"A complaint? Very well then, mr. Waters. Proceed" the mathematician sat most elegantly on his chair, crossing his legs, eagerly awaiting to hear what had caused his student's displeasure.
Waters took a deep breath, and spoke, under the curious gazes of his classmates and his mathematics professor.
"You've been repeating from the beginning of the semester that we students shouldn't  get involved with the local ladies...."
"That is very correct"
"But- yesterday, after our last lesson for the day, me and some of my classmates saw you....

"William, we really shouldn't- what if we are found...?" You whispered, as the very infamous professor lifted you off the ground, to help you sit on his desk.
"Relax, darling. The lessons have ended for today, and... If you stay quiet, no one shall discover us" he wrapped your legs around his waist and gave you a teasing smirk, his hands stroking your thighs.
"If you say so" he kissed lightly your forehead "That's right darling" he pressed his lips against yours gently at first, then lead you into a deeper, slower kiss. You let his mouth lead you into the depths of pleasure, your worries totally forgotten. When your lips parted, you were both a blushing, panting mess, you shyly pulled his tie and William followed, lowering his head to fill your neck with kisses and bites. You hummed softly,  he whispered sweet words inside your ear, then bit the earlobe, sending thousands of shivers down your spine, before diving once more in your neck. You did your best keeping quiet, but your lover sure did make it difficult. "W- William, kiss me on the lips" you spoke, and William immediately fulfilled your request, giving you the most passionate kiss a man can manage.

"So, I do not understand why we have to stay away from loving girls inside the school grounds, when our professor clearly hasn't" a smug smile could be seen on Waters' face. For a moment, he really did thought he had outsmarted the one and only professor Moriarty. Tate mentally questioned himself why hadn't he been more persistent when warning his classmate.
The classroom had felt silent - absolutely nothing could be heard. The students were looking at each other eide eyed, blushing, but none of them dared to speak a single word.
The young adolescents knew very well that Waters was, well, for lack of a better term, dead meat. They knew it by the gleam in their professor's eyes, that he didn't even stand a chance defending his opinion.
William James Moriarty chuckled, sitting up on his two feet.
"Thank you for sharing the reasons of your dismay, mr. Waters. I shall now give an answer equal to my...charges" he stood behind his desk, leaned forward and supported his weight with his hands on the firm wood.
"I understand what your point is, mr. Waters. But I am afraid that by "loving girls" you are referring to sneaking random young ladies from nearby pubs inside the school, which is strictly prohibited, and may result in the most scandalous situations..." William cleared his neck, before glaring at the young audience across him.

"Does what I say ring any bells to any of you? Perhaps mr. Anthony? Or you, mr. Gladstone?"
The two boys' complexions got extremely pale, but didn't mumble a syllable. William smiled.
"Now, before I go on, it shall be reminded that I am a married adult, and any erotic activity I may have with my wife, isn't the same as fooling around with ladies, drunk, instead of attending my classes. Do you agree, mr. Williamson?"
The redhead by the name Williamson averted his gaze "Y- yes sir" he almost whispered.
"Very well. I hope that the difference between you and me is now clearer. Furthermore, I am afraid you cannot prove your point, mr. Waters.  You said that there were some classmates of yours along with you? May they raise their hands?" As William had anticipated, no one moved a single inch.
"Then, you are the only one who claims seeing me and my dear wife, lets say, having some private moments. Therefore, it could very well be a lie to justify your own beliefs"
George Water's complexion had turned purple, and, as his classmates guessed, that moment he only wished to dig a hole on the ground and bury himself.
William smiled most innocently, even a small blush could be seen on his pale cheeks.
"I take it you have nothing to add? Good. Back to Algebr-"

Much to everyone's relief, the bell was heard from the enormous corridors of Durham University, cutting off their professor. William sighed.
"Dismissed. And don't forget your assignments for next week" William gathered his books and notes, carefully placing them into his suitcase.
"Hello, mr. Professor sir"
William's thoughts were interrupted by the same melodic voice he'd much like to hear untill his last breath.
"Darling" he breathed out, already by your side.
You stroked his cheek "I heard everything"  you giggled, "I told you it may result in trouble". You helped him put on his brown jacket, then the mathematician leaned in to press a quick kiss on your lips. "I admit defeat, my dear. I should've listened" he replied in a teasing tone, meanwhile grasping in his one hand both his cane and suitcase, his free hand was offered for you to take. "My goodness, I managed to outthink William James Moriarty. I must be rewarded" you jested, as you walked together out of the lecture hall. A small chuckle escaped his lips "A reward? Let's see... Maybe a kiss?"
"Ugh-uh, too little"
"My, I sure have a greedy darling. Then, how does a romantic moonlit stroll sound?"
"I think I'll take it"
