A/N: So, I had a bit of a problem with this series... I knew where the story was going but needed a couple of chapters in between so it wouldn't seem too rushed. I conveniently had a part written ready for this story from long ago that kind of fit here. When I first started writing this story, I wrote like 12 parts or so but realized I didn't like how the story turned out so I started writing an alternate version from part three I think... And well, I liked it better so here we are now. Anyway, hope you like this part.

Warning: angst, mentions of male masturbation, didn't go into too much detail (it was a lot more graphic before but I felt too weird about it so I changed it up)

Sitting at his desk while staring at the screen of his laptop, Chris had his chin resting on his hand as his mind raced. He was trying to read through some assignments sent by his students but he couldn't focus. All he could think about was what had happened during the night taking place between Friday and Saturday of the previous week. He shook his head after realizing his mind had started wandering again. He turned his attention back to the assignment.

After trying to get past the first sentence for what felt like the hundredth time, he groaned in defeat and slumped back on his chair. The wheels turned, causing him to drift away from the desk slightly. He rested his elbow on the armrest and leaned his head on his hand, rubbing his temple as he fought the urge to just flip the table in front of him.

Usually when he was working, he could leave everything else aside, let them store in the back of his head and only focus on his work. He loved his job, he loved to teach other people and help them learn. When he worked, he could forget about everything else for a while. At least that was how it was before you came along.

He had seen the looks you had given him on the very first day you had seen him. He had heard the odd tone in your voice when he had called out your name as you answered, "Yes, sir." It sometimes sent shivers down his spine just thinking back on the very first time he had heard you speak.

Your answer had been so soft, so gentle yet there had been a little ounce of lustful tone laced in your voice. It had been clear that you felt some sort of attraction towards him. Granted, it hadn't been the first time Chris had recognized those feelings in a student before but for some reason, he found you to be different.

He couldn't quite wrap his finger around why he felt about you the way he did. Sure, he was physically attracted to you but there was something much more deep within you that intrigued him. He hadn't even known you for that long but he felt like he was already hooked. All it needed was a few interactions between the two of you and suddenly he was addicted.

The fact that the two of you had slept together wasn't making things any easier. The night kept repeating itself in his mind. He may had had something to drink but the whole night was crystal clear. He could still remember every little movement you had made, every little curve of your body had imprinted itself into his memory. It was like his hands never even left your body. He could still feel you.

He found his mind wandering to the night once again, the way you looked, the way you responded to every little touch, every little word that came out of his mouth. It was so refreshing to be with someone so enthusiastic, so full of passion and need for him. 

He could still hear your moans, whimpers, the curses that left your lips while your eyes squeezed shut in pleasure. He felt your nails on his back, scratching his skin as you moaned out his name. He enjoyed having someone to please, someone to show him how good he made them feel. He enjoyed having someone to communicate with in such an intimate way and not feel like they were doing something just to get some relief themselves.

His eyes closed as his hand started moving down his body. His palm was slowly gliding along his torso over the flannel he was wearing. He pictured his hand as yours and slipped his fingers past the waistband of his sweatpants. His fingers brushed the part of his body that ached for your touch and he hummed in satisfaction. His head fell back and his mouth dropped. His breathing was getting heavier as he continued to think of you, think of the night you had spent together.

The night was vivid in his mind, it was as if he was experiencing it all over again and not just fantasizing. He whispered your name aloud but didn't realize it himself. He was in too deep with the mental image of you two together. He had lost all sense of reality in that moment.

He began to moan and his back arched against the chair. His hand was doing all it could to help him release the building feeling of pure lust rising in his body. He growled under his breath as he twitched slightly, nearing the goal he was trying to achieve and feel that relief rush through his body.

Chris's eyes shot open as he heard his phone ringing. He sighed in frustration and picked up his phone that was set on the desk next to his laptop. He lifted the mobile device and looked at the screen, seeing his wife's name plastered on the top of the screen. He ran his hand over his face before accepting the call. "Hello?" He asked a bit breathlessly.

"Hi, Chris," Reina's voice was heard from the other side of the line. "Is everything alright? You sound—"

"Just came from a run." He answered quickly. He got up from the chair and looked down, seeing his erection pressing hard against his pants, begging for release. He ran his fingers through his hair and headed down the stairs. "How are you? How's work?" He asked like he always did when she was out of town for work.

"Good. Listen... I think I need to stay a few days longer. Just thought that I should call you and let you know."

Chris sighed, going over to the kitchen and getting himself a glass of cold water to drink. "That's fine," he said simply. "Take as much time as you need," he said and gulped down the glass of water and set the glass on the counter.

"Okay, good." Reina sighed, sounding disappointed. "How are you doing? How's teaching going? Found your pet, yet?" Her laugh rang through the phone.

Chris cringed at her joking tone as he thought back on what he had been doing right before his wife called. He had been touching himself to the memory of being with another woman, a student.

"No, no." He tried to laugh it off. "Teaching is going well. I feel like I'm really getting through to the students."

"That's great. Anyways, I have to go now. I'll talk to you later?"

"Yeah, goodbye," Chris said to the phone, waiting for Reina to say goodbye to him as well before hanging up.

Chris set his phone his pocket and rested his hands on the marble surface of the counter. He hung his head low and took a deep breath. Once again, he felt bad for cheating on his wife. He was surprised how easy it was to forget at times.

Trying to clear his mind, he shook his head and headed back upstairs. He sat in front of the desk and looked at the screen of his laptop again. Instead of trying to finish what he had started with reading through the assignments, he put the lid down.

He rested his elbows on the desk and buried his face in his hands. It's like Reina had sensed something was off and contacted Chris when it was the worst timing for him. The timing is exactly what made Chris even more tense.

His gaze fell to his lap again, realizing he still had a bit of a problem to take care of. 

"Shit," he cursed to himself, standing up abruptly and sending the chair wheeling backwards from the force. He headed straight to the bathroom. He walked up to the sink and splashed his face with some cold water as if he could wash the problem away.

He took a towel and wiped his face dry before staring at the mirror. He shook his head in disgust. "What's wrong with you?" He whispered. "Your wife called you and you're still hard? How did that not—" 

He stopped as he felt his phone vibrating in his pocket. He groaned, taking the mobile device from his pocket and looked at the screen to see a text from Reina.

I forgot to mention I stacked up on shaving cream for you before I left. Just in case you run out, just know there's more in the cabinet under the sink. Take care. R

Chris shook his head, pushing the device back in his pocket before looking up at the mirror again. 

He found himself frowning while staring at himself in the mirror. He didn't look any different but be barely recognized himself. He never knew he would be able to do such an awful thing and cheat on his wife. 

What he had done was wrong, so incredibly wrong. He knew it, he acknowledged it and felt guilty because of it. But he also couldn't get himself to regret what he did. 

He didn't regret spending the night with you. 

He ran his fingers through his hair as he realized he really didn't regret sleeping with you. He turned away from the mirror, disgusted by his reflection in the mirror. He leaned back against the sink and stared ahead of him, sighing. 

He knew he shouldn't be thinking such things yet he couldn't help himself.  He couldn't stop thinking about you although he tried.

It was getting harder day by day. You didn't seem to leave his mind alone.
