Samantha runs the class as normal as possible

During the day Samantha tried her best to keep things under wraps both in class and in her mind by again ignoring Nate's gaze as much as possible. Though, he made no such effort, and often, she would catch him staring at her. Finding him gazing at her body, almost undressing her with her eyes often made her squirm in her seat.

Eventually, the lesson ended. This time, Samantha greeted everyone out and sat back at her desk. She spotted Nate still sitting at his seat towards the middle of the room.

"How about you get those clothes off and come here." Nate said confidently with a grin, not hiding any of his intentions anymore.

"Uh-u-um..." Samantha mumbled incoherently as she struggled to find the words to say.

"I've already said it's okay Samantha, you don't need to speak for these lessons." Nate said confidently. "Now let's continue from yesterday. Take those clothes off." He said grinning at her.

It was as if Samantha had no voice of reason at all anymore. The only voice she was listening to was her desire, as she quickly slipped out of her clothes, eventually standing completely naked at the front of the class.

"Hah, imagine if the other boys saw you walk in like this. I bet they'd do anything you wanted them to." Nate said with a smirk. "Or maybe, you'd do anything they wanted you to." Nate said following with a little chuckle.

"N-no that's not. I-I wouldn't." Samantha said in protest.

"Never say never Samantha. Did you ever imagine that a student would be able to get you to undress just by telling you to?" Nate said with a grin.

Samantha's face went red, but she felt so unbelievably hot, something she'd never admit. Nate was absolutely right. She did what he wanted her to. Her student made her continuously cum on his cock behind her husbands back. She let him cum inside her but not her own husband. And worst of all, this made her feel the horniest she had ever been. Standing there naked in her classroom at the convenience of her student.

"Hah, I'm starting to feel like the teacher here. Come over here and take care of this for me." Nate said fishing his already semi-hard cock out of his pants. It looked so much more intimidating than John's from the night before. She quickly tip toed bare feet and stood in front of him.

"I'm gonna stay sitting today if that's alright with you. I've had a long day." He said sarcastically.

Samantha knelt in front of him on the cold tiled classroom floor, completely bare nude ready to take his cock in her mouth. This time though, she lifted his semi hard cock up and went straight to licking his balls, making sure to look up and get his reaction.

"Oh-hah, s-shit you know me too well haha." Nate said, caught off guard but clearly enjoying himself not only from the sensation, but from the thought that she wasn't just following directions anymore. She was doing what she wanted and what she wanted, more than anything at that moment, was to please him.

"If only I knew how much of a slut my teacher was, I wouldn't have wasted this much time going home with my balls full haha." He said still enjoying the sensation as she moved her tongue up his balls, his shaft and finally wrapping her pretty little mouth around the head of his cock, tasting the salty precum she'd brought to the surface.

"F-fuck me. O-kay." Nate exclaimed as she worked up and down his shaft with her mouth, occasionally twirling her tongue around the head.

"Alright Samantha, stand up for me." Nate said with authority. Samantha obeyed, taking her lips off his cock and slowly getting up with a string of saliva still attached to the head of his shaft. She opened and closed her mouth clearly wanting more. Nate stood up and took his trousers off completely.

"I'll be nice now and take care of you a little too." He said into her ear as he rubbed down from her tits, her belly and finally, stopping at her wet snatch. He continued to rub up and down.

"Hmm-uhhhhhh-huh." Samantha exhaled a moan. She didn't know how she kept herself up, but she almost immediately felt an orgasm coming on. "Ohhh fuuuck." She moaned as he made her cum in what seemed like no time at all, now targeting her clit in particular.

"Haha damn you really are a horny slut. You came on my fingers and I haven't even really started yet." Nate said laughing looking at Samantha's face turning red. "Turn around." He said sternly.

"Oh-uh-um." Samantha mumbled awkwardly but quickly turned around. Almost immediately, he put a heavy hand on her upper back to bring her head down, exposing her holes to him completely.

"Haha what a view huh Mrs Rogers?" He said while laughing.

Suddenly, she felt something poke at her privates. It started stroking up and down her needy pussy and as she realised what it was, she was fighting the urge to back up onto it every second.

"Hmm uhh-mm." Samantha moaned in anticipation.

"Seems like it wants me inside. What do you say Samantha?"

"Uh-um I don't know what you mean." She said, trying to sound disinterested but quite obviously failing.

"Come on Samantha. Don't you want me to put it in? Don't you want me to fuck you?"

"Oh uh-um I don't know Nate. Ma-"

"So you want me to put my cock away and leave right now?" Nate said in a sarcastic tone, cutting her off.

"Oh...n-no!" Samantha said, her lust betraying her.

"Do you want me to put it in you? Fuck you? Make you cum?" Nate asked, confident of the answer he was going to get as he kept rubbing her wet slit with the head of his cock, teasing her.

"Y-yes..." Samantha muttered under her breath.

"Then I suppose I have to listen to my teacher and do as she says." Nate said as he sunk the length of his substantial shaft into her needy, wet snatch.

Samantha instinctually bucked and backed up onto his length, feeling every inch of him inside of her. Her mind once again went blank as she came on his dick.

"Haha once again Samantha, you really are a slut for my cock. Cumming in one thrust." He said as he kept his shaft still inside her, feeling the contractions on his cock. "I'm assuming that's a green light for me to keep going." Nate said with confidence as he began to fuck her with long deep strokes, feeling her wetness with every thrust, using some of it to tease her ass.

Samantha seemingly kept cumming, her head up in the air as he kept her on that high. With her constantly tightening and contracting around his cock it was as if her greedy snatch was trying to milk him.

"F-fuck." Nate said, desperately trying to avert an early orgasm but to no avail. But it didn't matter, Samantha was still cumming like crazy. "I'm cumming."

"Y-yes...fuck." Samantha responded, still in a trance induced by Nate's cock.

"Hah-uugh." Nate grunted as he sunk his cock deep in Samantha's slit as she was cumming too. As Nate came, Samantha's snatch contracted, milking longer and longer spurts of his load inside her. This time, she knew what was happening, but she didn't care, and in fact, she might've wanted it. It just felt right to her. Nate's impressive cock shooting it's seed deep inside her as if desperately trying to breed her.

"F-fuck you drained me this time Samantha." He said withdrawing his cock from her pussy.

"Well, thanks for that. I'll catch you later." Nate said casually as he pulled up his trousers nonchalantly. He quickly thought what her reaction would be if he spanked her and without much thought raised his hand and landed it on her ass firmly.

"Oh!" Samantha jerked up from her trance, but no doubt, her stinging cheek only added to the burning heat still in her loins. She was still unbelievably turned on.

As Nate walked out, she could feel his cum dripping and down her legs. The cold air of the classroom against her exposed holes and stinging cheek just added to the sensations which made her want more. She thought about the fact that the door was also unlocked. Perhaps the principal would walk in and find her? Maybe another student? What would they do if they found her like this? The thought of being used again turned her on even more. Someone walking in, thrusting their cock straight into her needy hole without warning, pushing Nate's cum deep back into her. Maybe they'd add to his load.

"Ughh f-fuck." Samantha moaned as she began playing with herself, feeling herself becoming more and more accustomed to the pleasure. Or maybe that was addiction she was feeling? She pushed the thought to the back of her mind as she felt herself getting close.

She once again came leaning on top of Nate's desk. She kept herself as exposed as possible, as the thought of being seen, of being used again was amplifying her ecstasy even more. Eventually, she slumped onto the desk, tired but satisfied.

She took a respectable amount of time before getting ready and going home, once again popping some plan B tablets in the car.

"Maybe I should get onto some birth control." She thought to herself, once again turning herself on at the thought that her she was considering something to continue to please Nate, despite the fact that her husband would never cum inside her. Did she want this to keep going? Maybe she should stop this before falling even further?
