Mathew was very careful for next couple of weeks. Most of the time he spent his time at dorms except weekends. Since it's weekend he's with Ryan, happily downing a fifth bowl of ice cream.

"Boys, you've been eating too much of that. May be you should stop." Amanda tried to stop them.

To which Ryan replied " It's just a little bit of ice cream mom. Nothing's gonna happen." and added "You have to go to bed now or else I can't wake you up tomorrow. "

Amanda left them alone as she went to her room mumbling something about waking up early in the morning. Ryan went to fridge and brought some more of that goodness for both of them who were watching something on discovery channel.

Monday morning Mathew woke up feeling groggy and moody. He doesn't even want to go to college, his nose is running slightly, throat felt itchy, his eyes were red as he never slept a wink last night. Yet, he went to college.

Mathew is in the staff room, just walking about after a few classes, talking himself out of going back to home as he has just one class to teach. Suddenly, he was slammed from behind to a wall before him and that someone started to attack his neck with their mouth. A tongue came to lick where his neck and shoulder met, teeth nipped and lips sucked at the same place. First thing that came to his mind was 'Not here. I don't want to get caught.' which was stuck in his throat as the fear of moaning loud won over as it felt too good even in his moody state.

A hand creeped to his front trying to untuck his neatly tucked white button up shirt. He caught it just in time, so the free hand moved up and unbuttoned first button. Mathew caught that too. This seemed to irritate the assaulter as they became aggressive with their sucking which earned a few moans. Someone's footsteps can be heard outside walking towards his room. Mathew's heart beat became faster as he feared he would get caught and the sucking became more aggressive hitting the nerve making him shiver with excitement and fear. Footsteps got closer, the tongue traced a train to his chin sensually. Footsteps got even closer, teeth nipped his neck sucking there now. He wanted to say stop or warn, but he couldn't as the first thing that will come out of his mouth is a moan. The door was burst open as a female professor came in stacking up the papers in her hand. Mathew has never felt such a relief when the assaulting body was gone and the professor was still looking at her papers.

After she's done arranging them, she looked at him weirdly and said "What are you doing?"

Just then Mathew remembered the position he was in; still attached to the wall slightly panting with hooded eyes. He thought faster and said "Lizard" she screamed dropping the papers she arranged just now.

Mathew stifled a laugh getting his composure back and said "Relax. I thought I saw it. It's not here now."

She sighed relieved and started pick the papers cursing under her breath.

Mathew couldn't be happier that the room has two doors. He always thought why the hell would anyone put two doors for a room which is as small as this. Now he's thankful for whoever did that.

Thinking these thoughts he forgot the time and was late to class. The first thing he said to class upon entering is

"Sorry every one. I just wanted to give you guys some free time to forget about previous class before I start today's class. It is a little bit complicated so please pay attention."

The topic really is complicated as some of them are struggling to understand it and some of them are having trouble concentrating in general. Mathew looked like a wet dream with disheveled hair and wrinkled shirt. He forgot to wear his glasses which elevated his blue eyes, slightly reddened. Him, loosening his tie because he felt constricted does it. To remaining people who were concentrating on the class. Half way into the class his throat felt dry so he reached to his bottle like usual, everyone is following his every movement with utmost concentration. Mathew's eyes went to Ryan, he quickly put the bottle on seeing his devilish smirk. His voice became more raspy due to the dryness he felt, but he would take dry throat any day before he have to deal with Ryan's teasing. What Mathew failed to notice is; his voice doing things to all his students except one who found the situation very entertaining. All in all there's no one in the class who hasn't fallen for his looks except a few straight boys who are extremely jealous that their girlfriends are drooling at him. Mainly the forbidden teacher-student relationship is what hooked every one in the classroom adding to his looks: he's young, smart and approachable on contrast to most professors in the college. Unlike them he appreciates a good joke, smiles with out any hint of irritation when students asked a doubt and he would even reply to mails.

As everyone is admiring the teacher Ryan thought it was his time to notch it up a bit as he got an idea from the current topic so he raised his hand.

"Yes. Parker" the teacher acknowledged him. After hearing the question he answered. "You're confused about two main things here. Apex and base are two different things" he said as the topic concerned prisms "you had the basics in high school, you can't be confused with these things now. So let me clarify that before I move on further" and turned to board to draw a triangular prism. He pointed to the bottom half of the prism and said "This is the base of a prism and this pointed one is Apex"

"How can you say what's base and apex when the prism doesn't have a pointed surface? " Ryan asked feigning confusion.

"Well, you can say it by the thickness. Generally, the apex would be thinner and the base would be thickest." he said gesturing with his hands. "It's the same for lenses too. For example," he drew two shapes which looked like half moon and hour glass turned to Ryan saying "even for these two shapes the thin part is apex and thick one is base."

"How thick is the base?" someone asked.

"The individual measurements doesn't matter. It can be of a millimeter, ten centimeters or five inch thick" somebody gasped at that which wasn't noticed by the teacher as he continued with his deep raspy voice "All that matters is, it has to be the thickest when compared to other measurements of an object."

There were murmurs from Ryan's side, he thought they were having troubles to understand topic so addressed them "If you have any questions ask me. They don't get clarified if you talk among yourselves."

"It's nothing Mr.Collins. I was saying it would be easy to remember like a di- penis. Thick at the base." Alex said.

Mathew looked at him for a moment with a blank expression. Everyone thought Alex was going to get in trouble, but Mathew said "You'll get even more confused if you don't take example of a prism."

A girl in the first bench asked "So it's not a prism?"

"Correct me if I'm wrong, it's cylindrical and cylindrical objects are not prisms."

"What's the difference? It's three dimensional." someone asked.

"Being 3-dimensional isn't the only characteristic of a prism. It has to have faces. Whereas a di- I mean cylinder have a curved surface not faces." and he couldn't help but ask "Didn't anyone pay attention in high school?" he looked at Ryan as if to ask 'Really?'

His smile gone after that as his mood became even more shitty as he concluded that he's gonna get cold. He could handle it if it's just a cold, but no. It has stages. First his throat will become sour and scratchy, next comes body pains then cold and finally fever. Only then can he be normal, this whole process takes a week at the latest. Feeling hot he unconsciously opened a couple of buttons of shirt after loosening his tie further as he dived deep into the topic. It seems he's not the only one who's feeling hot as the whole room became hotter because of all the hormones. All the girls fanned themselves involuntarily with their hands.

Mathew heard murmurs which made him snap "I told you to ask me if you have any questions." normally he is a patient man. The aggressiveness just added to it.

A girl in front of Alex, who's the cause of murmurs by having a heated argument with him asked "Are you gay?"

"What?" Mathew didn't know how that came suddenly.

"Or Bi?" she asked again as it was their argument.

"What does it have to do anything with the class?"

"Because" she pointed at his neck which he mistook for the board, turned towards it finding nothing but the theory he was explaining.

"Sorry?" he asked again. She pointed at her own neck and later his.

Mathew is still confused as he touched his own neck and hissed when he brushed the evidence of previous assault. Ryan who was smirking cockily got a glare from him before he replied "It doesn't matter because I'm taken" he pointed at the hickey with a finger continuing "and I don't date my students." his eyes involuntarily went to Ryan who mouthed 'Lair'. He straightened his shirt feeling self conscious and said "So, if your questions doesn't involve the topic I would like to continue the topic."
