“Please make sure to read chapter 5 of your textbooks before tomorrow.” Mr. Kelly announced as the bell rang and students began collecting their stuff. “But Lucy, I’d like to see you after class.”

Lucy looked up from her detailed History notes and blushed. Had she done something wrong? “I thought my grades were perfect...” she whispered to herself as the class cleared out for lunch, leaving her and her teacher alone.

Mr. Kelly, a handsome brunette man in his early 30s, approached her desk and sat next to her. “Lucy, I wanted to talk to you about your grades. I know you’ve been aiming for Valedictorian this year and I’m afraid it looks like you’re close to failing.” Lucy turned her head to try and hide the tears welling in her eyes. She could have sworn she’d been doing better than ever. “I know it’s been tough on you since the TG Flu turned you into a girl, but I’m worried you’re not doing your breast-*ahem*, I mean, best.” As his young pupil looked away he snatched a glance at her generous sweater puppies. A couple months ago Luke had gone from a young acne-ridden male nerd into the cutest, bustiest girl in school that every guy was salivating over, even though they all knew that she was originally a he. It didn’t help that she seemed blissfully unaware of just how desirable she was, and that she constantly wore his skirt so short.

“I-I’m so sorry, Mr. Kelly!” Lucy cried, tears running down her face. “I had no idea! I really need to pass this class so I can get my dream university scholarship! I’ll do anything!”

“Anything?” That was what Mr. Kelly was waiting for. “You’ll really do anything?”

“Anything, sir!” Lucy replied, desperate to maintain her perfect academic record.

Grabbing Lucy by the wrist he pulled her hand to his crotch, her delicate fingers pressing against his hard dick through his pants. “You remember what this is, right?”

“Oh, uh, sir!” Lucy gasped, pulling back. “I-I don’t think this is appropriate!”

“I thought you wanted to pass Math, right? I’m happy to help you with your grades if you’re happy to ‘suck up’ to me...”

“Oh, um... okay, I guess if it’ll help my chances...” Lucy said, consigning herself to her fate. Unzipping Mr. Kelly’s fly and unbuttoning his pants, she reached into his boxers and extracted his whopper 10-inch dong. “I-it’s enormous! I don’t think I can fit this in my-” she was interrupted as Mr. Kelly grabbed the back of her head and forced his way into her mouth, making her gag and her eyes water as she took inch after inch of his thick member inside of her. “Mmfhfmhh!” Lucy mumbled, using a hand on his cock to stabilize herself as she tried her best to give her first sloppy blowjob. As she did Mr. Kelly reached down and grabbed handfuls of her soft breasts, sending previously alien sexual sensations through her body as she truly felt her femininity for the first time.

After a few minutes of heavenly sucking, Mr. Kelly pulled his cock from her mouth and pushed his student onto her back on the desk, hiking her skirt and spreading her legs. Lucy covered her eyes in embarrassment. “What are you-AH!” she squealed as she felt her teacher penetrate her tight virgin pussy, thrusting in and out as the two were joined in carnal desire for an age. Lucy felt so vulnerable, but that only seemed to enhance her submissive pleasure until she felt her partner seize up and moan loudly as he came unprotected inside of her.

Collapsing on each other tired and overwhelmed, each enjoying the pleasant afterglow, Mr. Kelly stood back up and began putting his pants back on. “Great work, Lucy. I think you earned yourself an A+ for the upcoming assignment.” Heading back over to his desk, he opened up the student grade record. “Although if you want to maintain your grades, we might have to fit in some more ‘private tutoring* next week.” He looked down at her record and mimicked entering a perfect grade. She was doing perfectly already - although he figured it was for the best to keep that on the down-low for now.
