"Gee, Ms. B.! Your tits are making circle marks on the chalkboard!"
I couldn't see them. He had me pushed up against the chalkboard with one hand in the middle of my back and his other hand cupping my pussy from the front. My face was sideways with my cheek against the board and the palms of my hands were flat against the board on either side of my head. After pulling my shirt and bra up over my tits, he had roughly mauled them before pushing me up against the chalkboard at the side of the classroom. He held me there while he reached up under my skirt and pulled my panties down past my knees.
"Fuck, you're wet!" he exclaimed as he rubbed back and forth along my sex.
It was true; I was oozing. I could only whimper and try to spread my legs farther apart.
He removed his hand and I heard him unzip his pants. The next thing I knew he had effortlessly shoved his cock into my waiting cunt.
"Oh, god..." I managed to moan as the length and girth of his cock surprised me. However, the ease with which he penetrated me was not a surprise. Since I discovered the latent sexuality of the senior class and how I could use them to satisfy my own unquenchable yearning to fuck and be fucked, I had taken advantage of every opportunity these highly-sexed eighteen year olds provided. This was one of those opportunities.
"Chad, not so hard... Uh..." I begged as he pushed me against the chalk tray with each thrust. He ignored my plea and kept pounding me with that oversized, teenage cock.
He was a big boy, way over six feet tall with a physique and strength to match his size. I guess it should have been no surprise he had a cock to match. He had told me he didn't go out for sports because he liked to do too many other things. Maybe this was one of the other things he liked to do. I silently wondered how many girls in his class had been pleasured by his cock.
"Oh, god, Ms. B.! I'm coming! I gonna come! Oh, yeah, yeah! Oh, fuck!" He pushed me harder against the chalkboard, mashing my tits even more, and bucked his cock up into my compliant cunt as I felt spurt after spurt splash into me. God, it felt good. Even though I hadn't come this time, just feeling his hard cock and the amount of cum he dumped into me almost made me dizzy. There was no denying that I was the fucking teacher.
He was still hard and didn't pull out, but instead, reached between us and stuck his finger into my cunt alongside his cock. This gave me a brand new sensation.
"Oh..." I gasped as he smeared his finger with both our juices. Then, without warning, he pulled his finger out and stuck it into my ass.
"Aaaayyyyeeeee..." I wailed as I came immediately, succumbing to my pent up needs, even as my hard spasms were suppressed by him pushing against me.
Before I had a chance to completely savor the moment, he had pulled both his finger and his cock out. I cried a silent "Noooooo..."
"Oh, Ms. B. I'm sorry. I didn't know that would happen. Greg told me I should do that. He said a girl he used to go out with told him to do that and it would drive her crazy. Are you O.K.? I'm sorry."
"Chad, it's O.K. It's O.K.," I reassured him. It must have been the first time that a girl had come on his finger up her ass. It was a fantastic feeling and I thought I needed to let him know that it was O.K. to do that. I regained my strength and turned around. He was leaning back against the lab table.
"Chad, it was just the right thing to do and the right time to do it. Don't worry about it. It was great!" I said as I pulled my panties up so his bucket of cum wouldn't leak out, smoothed my skirt, pulled my bra down over my tits, and positioned them comfortably. I looked at Chad and he was just watching me, leaning against the table. He spent, shiny cock was still out; it must have been six inches long! I smiled as I pulled my shirt down and said "We'd better get decent now."
