Today was orientation day at my new all-girls school. The teacher is a little strange, but I think he is sexy! The school takes birth control and sex education very seriously. Vaginal sex or masturbation is not allowed, and it is required for students to wear a butt plug 24/7. Their studies show that it improves test performance. The teacher wanted to see that I'd been wearing my plug. I showed him I have been practicing and took it out several times. He said that for today's orientation, I would be learning about ass-to-mouth. I don't know what is it? After sucking on his cock to make sure it is hard he fucked my ass. It felt amazing! Sometimes he would take it out and tell me to suck on it. It's really sweet! Then he sat down and asked me to demonstrate to him cowgirl. My ass is so greedy for this position! Balls deep is my style and I started bouncing up and down sliding his cock deep into my asshole. I even showed off my reverse cowgirl skills too. Finally, he said he had a treat
