You shove it up your ass

You jump onto your teacher, he lays you down and shoves his cock up your ass. You moan louder and louder as he continues to thrust into you. "OH YEAH FUCK ME HARD SIR!!! OH YOUR COCK IS HUGE, I LOVE IT!!!" You scream at him.

He carries on fucking harder and harder until he cums in your ass. However when he does your vision starts to blurr and you fall ****.

You wake up later trapped in a chamber, you have no idea what is going on. You have clothes on, which is strange because you don't remember them on. Then someone walks in. It is Dr Evilini!

She looks at you and says: "Hello Justin! Never thought you would see me again did you?" You are shocked and reply, "Dr Evilini?! What is going on?! I thought you were arrested for trying to steal my powers when I was at Wiztech!" "Yes but I have escaped and I have got you now. You see Justin I need your powers, so I used one of my students to poison you so I can grab you and now I will be the strongest wizard in the world!!!! Ha ha ha ha!!"

You are so scared you don't know what to do. She leaves. Suddenly you feel your crotch grow and it is harder and rougher than ever. Like a nail file.
