Didlo in the ass ( butt plug )

When I was going at school, I had I fear with my asshole. I want to make it bigger cause I thought it was too small. So I thought when I had private lessons at my house I could put me but plug on my ass. This made me so horny in the lessons that I liked it so I decided to put my butt plug and at school. At the beginning it was okey and after some time I got used to and I felt any difference. But in one lesson at maths at my home I got so horny that my teacher understood that I was using something in my ass. She told me to take off my pants to see I was doing.At that moment I felt very shy so I said no, I she told me she would told my mom what I was doing if I didn't have taken off my pants. So without a second thought ( because I didn't want to be punished) I took them of, and she so my butt plug! She asked me if she could touch my pussy and my ass and I was so horny to say no. Immediately she start masturbate my pussy and kissing it . Then he kissed together and liked each other's boobs . After that she started fingering me until I cumm . That was my first ever sexual contact. After that I never took off my butt plug at me lessons and every once in a while we have sex with my theacher
