"Take your clothes off, and bend over"

"... Take your clothes off, and bend over my desk," she commands. She days this with so much **** that you don't even think about what you're doing. You just quietly slide your pants down your legs and take your shirt off.

"Everything," she commands. You hesitate and she rips your boxers off and bends you forcefully over her desk. One of her hands reaches around and grabs your semihard cock. It stiffens immediately and you let out a little gasp. Ms. Nanci laughs. "It's so small! Hold on.."

Ms. Nanci fumbles around in her desk and pulls out a tape measure. She measures your cock. "Only eight inches," she says. You can hear the laughter in her voice. "C'mon, measure me," she commands as she takes her skirt off. Your breath catches in your throat as you see the massive bulge in her panties. It looks like someone stuffed a can of tennis balls in her underwear. You slowly pull the panties down her legs, and her dick flies out of it's too-small confines, practically bitch slapping you as it comes out. Her cock is semihard and hugely thick Ms. Nanci laughs. You bring the tape measure up to her huge cock.

"Elev...no, twelve inches," you say nervously, as you know she's not even fully hard yet.

"That's right. We're going to be using my cock for this little extra credit assignment. Now bend over."

You do as she says. Ms. Nanci leans over you again, and you can feel something massive probing your sphincter. It actually feels pretty good. You stick your ass out a little farther, wanting to feel the sensations even more strongly.

"Hah, you little slut," Ms. Nanci laughs, as she continues probing your ass with her massive cock.

Suddenly, Ms. Nanci sticks more of her cock up your ass. You cry out in pleasure. She goes slowly at first, but quickly picks up speed. You've never felt anything like this before. It feels amazing. Before you know it, your vision goes blank and your dick spasms, sending loads of your cum onto the carpet.

Ms. Nanci laughs and leans forward. "That was only the first couple of inches of my dick, you know." You flush red in embarrassment.
