Busty school girl Bella Luna takes the D in order to get the A

Bella Luna had bombed her exam and blown off the makeup, leaving her grade hanging by a thread. Desperate, she slipped into her professor's office after hours, pleading for one last shot to pass. He'd already given her too many chances and watched her waste every one, but tonight he offered a filthy deal: she could wrap her lips around his thick, throbbing cock and earn that passing grade with every sloppy, desperate suck. Bella didn't hesitate. She dropped to her knees, yanked his zipper down, and attacked his hard shaft like a starving slut, tongue swirling, throat opening wide as she took him deeper, gagging and drooling while he groaned above her.
