She came for office hours... but stayed to surrender. Grace thought she was just failing a class-until she walked into Professor Kane's office and realized she was about to fail control, too. What starts as a desperate plea for a second chance turns into a twisted, tantalizing education in obedience. With every private session, Kane pushes her further-testing her patience, her limits, and her soaked desire to please. But she's not alone. "One mouth opened the door. Two tongues kept it wide. Three bodies surrendered together." Grace, the perfect student with perfect grades... and a perfectly filthy streak. Ava, the teaching assistant who obeys with her mouth before she speaks. And Lena-the innocent newcomer, untouched and eager to learn. "This syllabus ends with a squirt." As plug-filled lessons turn into shared service, vibrating denial, and wet, writhing submission, Grace finds herself on her knees in more ways than one. But in Kane's world, pleasure is earned, punishment is precise, and good girls don't just make the honor roll... They make a mess. "They came for extra credit. They left dripping with praise." This is a high-heat, high-control, wet and messy erotica you won't forget. You've been warned-class is in session.
