Doggy style.

I don't know why, but I decided doggy style, maybe it was because it would feel awkward looking into the teacher's eyes, maybe it feels more fun, or maybe I just wanted to show my arse. Either way I was sure that that was the position I wanted. I also decided to strip right there, which was nerve wracking, but strangely exhilarating. Like, I had never really been the rebellious kind (Ok I was basically little miss perfect) but something about how naughty it all felt seemed quite intoxicating. I guess I was kind of sexually repressed. Anyway as a took the position on my hands and knees, fully naked and facing away from the teacher, she asked "Is that how you want to do this?" I nervously nodded and waited for the feeling of the strange tentacle inside me.

The tentacle inside me felt like nothing ever before. I couldn't help but moan and gasp as soon as I felt it in me. My heart was already racing out of nervousness beforehand, but now it was beating as fast as it could. The warm pleasure started in my pussy and radiated outwards across my entire body as I submitted to the strange thing inside me. I was completely lost in the sensation when Mrs Braithwaite asked

"How are you doing there"

"Excellent" I moaned.

"Well, just to remind you, if you feel uncomfortable, or want to stop, do let me know ok?"

"Will do"

And just like that, I got lost in the sensation again, seconds stretched into minutes, minutes into hours, until suddenly. I then felt close to the most powerful orgasm of my life when I heard her speak again.

"I'm about to come, you ready?"

I bit my lip and simply nodded, doing my best to look back at the teacher who had her "cock" in me. She then let out a strong moan at the same time I did. I don't know how I came so much, or how we managed to time it perfectly. Either way I was lost in the sensation and couldn't be brought out.

"How do you feel?" she asked as I was just coming out of it.

"Good" I answered dreamily. "When will I start to get the effects?"

"Well, I recommend in two days from now trying to get at least one creampie a day, and within three weeks, you'll you'll start to notice the thing poking holes in your clothing, and in a couple more after that, you'll quickly lose bladder control. I recommend you go to the toilet as normal, until you start getting holes in your clothes while in public. Then, don't worry about it, just let it happen. See the nurse if you are having problems. However, I did say you could have a go peeing here and now to get used to the idea, so if you need to go feel free."

I kind of did need to go, so I squatted down, but nothing would come out.

"Well, it seems you can't go right now. If you'd like, you can always come back to my class after school to try again, but you might get into trouble if you start peeing among the general public before you really show."

"Urm, thanks" I stammer, before leaving, not quite sure how to process this. I wonder what my parents will think: I know my dad wouldn't accept sex before marriage. And then there's the whole peeing thing. Sure public places are being designed more to handle it with drains and cleaning, But what about home?
