Enlist his help.

"Frank, will you help me against the other's attempts to humiliate me?" You ask with a bounce on his cock.

"What is in it for me?" He asks.

"What would you like?"

"Make sure I pass the class."

"What? Really?"

"Yes, I know I am not smart, but I am a hard worker. But if I fail this, I get tossed out onto the street and my options dwindle."

"I think you are smarter than you give yourself credit for. I will pass you, and I will do my best to teach you. Will you help me against these bullies?"

"I will. Thank you Miss T."

"No problem, coordinate with Brad, he is also helping me. but on a different note..."

"I don't think I should cum inside you."

"Agreed."

You strip your shirt off and spin around to face him then you get back on his cock.

"Tell me the moment you are cumming, ok?" You say.

"Trying to make it last to the last possible moment, that's hot." He replies.

You fuck him slow and steady, grinding your pussy on him with purpose. You cum 3 or 4 times, because of the aphrodisiac still affecting you, but you still have perfect control of your body.

"I'm close." He warns.

You keep fucking him.

"When I say 'now' I will cum." He says.

You continue fucking him. You feel his cock start to pulse.

"now!" He groans.

You are at the height of a thrust when he says that, his cock is already mostly out of you but you want to be risky today, emboldened by your humiliating Trish and turning the tables on the students. You drop down all the way. You feel a spurt of cum deep inside you. You then jump off his cock and drop to your knees to quickly take him inside your mouth. You swallow everything he gives you.

Afterwards, he leaves fairly quickly, mumbling about being late. You scoop his cum from your pussy and suck it from your fingers.

You clean up and get dressed and head home.
