The Biology of Music - I fucked my trans substitute teacher

“Just fuck me as hard as you can and fill me with your cum. I have to have you in me. Please”

This is the invitation I need, and with the fear of prematurely cumming gone, I push my cock into her asshole, deeper this time, and then deeper again and then withdraw and then I push it all in. She screams when my cock is fully inserted, and I start fucking her as hard as I can. I pull it out almost all the way between thrusts and then push it in all the way. Her head is turned upwards and I start kissing her neck. It is the most amazing experience of my life. I start wanking her cock as I’m fucking her, and she is in ecstasy. I am a little bit worried about the noise, but at this point I don’t really care. I don’t care if I am kicked out of school forever, this is such an unbelievable experience.

I am getting so close now, So we start tongue kissing again and I start wanking her cock very hard hoping she can cum before me. It’s no use though, I can’t help it and I start to cum. I am almost aneurysmic in my orgasm and I feel my cum slosh around my cock in her asshole as I cum. She is screaming in delight as I cum, which makes me cum even harder. As the last drops of cum leave my cock into her asshole, I realise I’m still horny. Usually after I have cum, I have lost all interest in sex, but I still want to fuck her so bad. I go to start again, and she stops me, stares into my eyes and asks, “You’re amazing. Are you still horny?”

“I’m so fucking horny”, I respond. “I could fuck you all day”.

“Well if you like, you could clean me up before you finish me off and we go back to class”.

“Whatever you want me to do, just name it”

“My ass is full of your cum”, she stands up from the piano and goes on all fours onto the floor. “I’ll need to be cleaned up before I go back to class. I can’t teach biology with your cum in my ass, can I?”

I understand what she wants, and bring my mouth down to her asshole, as my cum starts to ooze out. I suck up every drop, and hold it in my mouth.
