My teacher v

My dick felt like it was numb being hard for so long and no attention paid to it. My butt wanted more, the boy woke up something in me. Wanting to cum I looked between my legs to see if Mr. Roberts was ready for me. The boy was leaning towards me holding the desk. Mr. Roberts was behind him licking his butt and fingering him. I wanted to cum so bad, I didn't care if I failed math. All I knew was my balls hurt, my dick and hips were numb from being in this position, and my butt ached for more attention. I was reaching up to stroke my dick when I felt a sudden pain and a smack sound. The boy had slapped my butt, which caught me off guard and woke up something.
I heard Mr. Roberts say something but I couldn't understand him, the boy reached up and squeezed my balls which hurt but to feel someone touch them was good. After a minute of squeezing, he pulled them tight which made me want to cum even more. He stopped rotating his finger in my butt and pulled it out. It felt funny, my hole tingled from the stretching now it throbs wanting to feel more in it. He wiped up some pre cum I had dripping and using it as a lube he rubbed it on my painful dick. Within a couple of minutes I was about to cum, when I felt pressure on my butt. Mr. Roberts had his hands on my butt, a finger pushed so slightly into my butt. The boy released me and stepped to my side, taking my hand and putting it on his dick. I wrapped my fingers around it and started to stroke.
My urge to cum grew as I was being stroked. Mr. Roberts suddenly shoved his finger in me deep and rotated, I couldn't take any more. I came so hard, my body shook, I felt my butt sucking the finger in it, and I was stroking the boy as quickly as possible. He was holding the desk and my arm. As my balls finally emptied the boy shot his second load, we collapsed on the desk panting. Squeezing my balls Mr. Roberts milked the last out of me. After we all caught our breath, and dressed he said he wanted me in the morning and the boy in the after school. We left the school and I found out the boy lived two blocks away from me, as we talked about being with our teacher he said he liked my dick and my butt was so tight. I asked if that was a bad thing, the boy said no but it'll hurt if you want a dick in you. I asked why would I want that, he said it feels good. Confused with what he said, we made plans to meet Saturday and do things.
