Accept the offer, you need the grade bump.

Much to your surprise, everyone at school was very accommodating of your 'disability' the next day. It seemed as though the other boys who had experienced Ms Kibur's **** were especially understanding. They would often go out of their way to make sure you didn't need help. It made it all that much easier. Not to mention the girls, who looked at you with a rare mix of lust and fear. It was very eerie. Additionally, there were little to no problems with the teacher's as far as your uniform went, barring an offhand comment or two, it was as if nothing had changed, But it had, they all knew your arrangement with Ms. Kibur and understood the situation. However, you could tell they all had a hint of jealousy too at Ms Kibur's find.

Besides that, your day went relatively normal, until you had to report to Ms. Kibur's office. This time, she was grading papers so you had to wait a bit before she would have her way with you, but in preparation she had you lube up her cock with your saliva. This was a difficult task indeed, considering the sheer size and weight of it, but you had ****. You took up her unwieldy penis and slowly began running it through your throat. Your mouth moved the entire distance of her cock, head to base easily, much to your surprise, yet still difficult.

As you ran your mouth along her penis, you spent every free second trying to suppress your gag reflex, afraid of what she might do. However, it was very pleasurable, sort of filling in a way. This was where you belonged, below her desk pleasuring her, and only her. You could feel every inch, every vein, every bulge in your mouth. Before long you felt her pulling out, like a baby with her pacifier you felt yourself resisting, hoping for just one more second. Once it was out. you really got a good look at it, specifically the lipstick ring you had left around its base.

"Get up."

You complied nervously.

"There we go, bend over."

Here you felt safe, bent over her desk again. It was familiar, you allowed yourself to breath a sigh of relief. All would work out fine, your stomach had already started to go down in swelling and you actually liked your new school uniform. You felt a breeze in your testicles as she pulled your panties down and lifted your dress. You heard a laugh when she saw your erection, but you didn't care.

"Please fuck me!"

You heard yourself say, to your surprise. You were only met with a grunt, but you could tell you would get what you want. Her hand shot up and grabbed you by the hair and her dick shot into your ass. You forgot how big she was already as you felt a major pain at this. In seconds she began destroying your poor hole, and arching your back as she yanked at your head. You squealed like a little girl, giggling with glee, it didn't hurt as much as it felt orgasmic. However, she was brutally quick, already shooting her load up your unprotected ass. You felt her semen rush up your body and meet yesterday's batch. She immediately pulled out as she was obviously expecting splash-back, and rightly so. Without even letting you cum she made you lick up the mess she had made over her chair and desk and then kicked you out.

You couldn't help but feel used and angry that she didn't even get you off. Fortunately you didn't feel this for long as you were unexpectedly ambushed by a bunch of...
