Homework or Detention?

I don't own Please Teacher, I am just a fan.

"Mr. Kusanagi, have you once again forgotten to complete your assigned homework?"
Kei stopped staring out the window and brought his attention back into the classroom. He looked up at his teacher and wife, both of them knowing fully well that last night Kei had been distracted by her and not completing his homework. "Sorry, Kazumi-sensei, I had something come up at home last night, can I get it to you tomorrow?"
"That is not good enough, Mr. Kusanagi. You will stay behind this afternoon for detention and complete it then." Mizuho turned away and smirked in delight.
The rest of the day passed without anyone questioning why Kazumi-sensei was being so tough on Kei and now he sat staring at his teacher, bored beyond belief. The homework she had assigned had been a piece of cake and had only taken about 15 minutes to complete, but for the past three quarters of an hour Kei had been just sitting waiting for Kazumi to tell him what to do next. He knew how much she loved these punishment games, using her position as his teacher to control and command him. Outside the voices of the other students could be heard as they were leaving after their club activities.
Mizuho stood and made her way towards where Kei was sitting. Standing next to Kei she asked, "So Mr. Kusanagi, having finally completed your homework do you have any questions?"
"Only one, ma'am, why did you keep me here for so long? Detention was over long ago." Kei asked looking up at her. The sun was setting, casting an orange glow over her.
"Wrong again, Mr. Kusanagi, your detention is far from being over." A smile played across her lips as she said this causing Kei to wonder what on earth she had in store for him. To nervous to make eye contact with him Mizuho slid herself in front of him, sitting on the desk and placing her feet either side of his chair. Looking out the window she lifted her skirt slightly, "Lick it clean", Mizuho could barely say the words and a blush crept across her cheeks.
Just hearing her say the words made Kei's cock throb and the sight before him made him rock hard. "Yes, ma'am" Kei whispered. He wrapped his arms up under her thighs, gripping her hips he ran his tounge along her slit, gently flicking the sensitive nub. "Ma'am you are dripping wet already" he informed her before lapping up her salty yet sweet juices
"Ah, oh, Kei" Mizuho breathed as she ran her fingers through his hair, gently pressing Kei closer to her clit. Taking the encouragement he relentlessly flicked the tip of his tounge over and over again causing her to buck her hips slightly. Kei then moved one of his hands away from her hip and pushed one of his fingers into her moist hole. Mizuho gasped in shock but soon relaxed herself into the feeling as Kei pressed two more fingers into her. Stroking her inside and manipulating her clit was sending Mizuho over the edge, Kei could feel the walls of her core tightening as her breathing got harsher and shorter. He looked up to watched her face as she came, "Oh Kei" she rasped before biting down on one of her fingers in an attempt to quiet her cries.
Kei leaned back in his seat and licked his fingers as he savoured the most delicious look of his teacher recovering from her orgasm. Noticing the smug look on his face Mizuho became annoyed, this was meant to be his punishment after all, that wasn't the only thing she noticed though. Pressing her foot into his crotch she looked at him questioningly, "What is that you have in your pants, Mr. Kusanagi? show it to me."
"Umm... ma'am, I don't know if..."
"Are you going to disregard an order from your teacher? Show me, Mr. Kusanagi, this is a priority one!"
Still with her legs either side of him, Kei stood, undoing both the belt and his pants slowly secretly hoping that at any moment Mizuho would stop him. Sighing in defeat he pulled both his trousers and boxers down in one swift movement. Mizuho reached out with one hand and rubbed a thumb over the head of his already weeping cock cauing Kei to shudder and let out a gutteral growl. While still grasping his engorged cock in one hand she reached up with her free hand to begin undoing the buttons of her vest first and then of her blouse, revealing a lavender coloured lace bra. "Now Mr. Kusanagi, I want you to fuck me. Right here on this desk so that every day you will be reminded of the consequences of not completing homework that I assign for you. Do you understand?"
"Yes, ma'am" he answered, subconsciously moving his hips further forward, completely forgetting the location in which their little trist was taking place. Mizuho guided his penis to her eagerly awaiting folds, leaning forward she captured his lips in a kiss just as he pushed the tip into her entrance. He shoved his entire length into her, savouring the feeling a moment before pulling out and ramming into her again. With each thrust Mizuho's tits bounced in front of Kei's face, they were so tempting that he yanked her bra down, causing them to fall out. Eagerly he latched onto one and massaged the other with the palm of his hand.
"Oh Kei, harder" Mizuho whispered in his ear, wrapping both her arms and legs around him. Though his movements were more restricted he pounded into he warm pussy harder and harder recieving many pleased moans of his name. The feeling of her tight wetness combined with the seductive sound of his name caused his cock to tighten.
"Mizuho... I... I'm about to..."
"Oh don't stop, I'm so close, harder Kei!"
Kei lifted his teacher from her sitting position and held onto her firm ass, with her wrapped around him he bounced her up and down, his cock slamming all the way into her. The new angle and depths that he was reaching caused Mizuho to cry out in pleasure and claw at Kei's back. It all became to much for Kei who spurted his thick seed deep inside his teacher with a cry. As he rocked her a couple more times along his cock Mizuho too reached her peak, leaning back and wiggling her hips as warm waves crashed all over her body.
Kei set her back on the desk and looked into her purple eyes as she attempted to catch her breath. Thought her skirt was hitched up and her breasts still exposed with erect nipples she fixed him with a very serious look. "Now I hope you understand the consequences of not completing your homework, Mr. Kusanagi. Well? Do you?"
"Oh yes ma'am" Kei said smiling, "I won't be completing my homework for a long time to come."
