Anal punishment

"Is this some kind of joke to you?"she screams at you?

"What the heck? What are you talking about?"

"I got an 'F' on the paper. Did you honestly think I hadn't already checked the grade first thing?"

She starts pulling down your pants and lowers your boxers so your base ass is exposed.

"What? That's impossible." You say.

She's really upset now. "Because of you I'm going to fail this stupid class and flunk out."

She reaches around and grasps your caged cock, merely checking up to make sure you're still fully locked.

"Please I swear I don't know how that could've happened."

"It's too late for that now!"She quiets you down

She pulls something else out of her bag. You can't tell what she's doing.

Then you jump. Her fingers are spreading some cold gel against your asshole.

"If I can't pass my class, I'm going to at least have some fun.."

Then you turn your head and see it. She's got a strap on attached to her waist. You feel the pressure of the tip against your opening.

She grabs your ass cheeks and pushes slowly in.

"I'm going to fuck the high school valedictorian."
