"Golly, Mr. Grant, you're practically slobbering all over 'em!" squealed twenty-one-year old Karen Johnson. "Honestly, I don't think I've ever met a man who was so crazy about my big titties!"

Bill Grant was too distracted to answer. The handsome, forty-two-year-old instructor was seated behind his desk in the now-deserted classroom, on the grounds of the little known Rickman-Hymer School of Dental Studies.

Karen was standing beside him, her blouse unbuttoned and her double D-cup bra unsnapped to free her enormous tits from confinement. Dazedly she looked down at her teacher as he slurped feverishly on her giant tits, his mouth ovalled around one wide, coral pink nipple, puckering his cheeks as he hungrily slurped the fat, rubbery tit between his lips.

Karen grimaced, suppressing a mewl of pain as her horny instructor grazed his teeth against her sensitive nipple flesh. But she decided not to say anything, and instead stroked Mr. Grant's hair as he kept sucking and slurping feverishly on her jugs. After all, she told herself, this was going to be his last sucking session with her big titties. And he certainly deserved the reward of being able to nurse on her giant tits after giving her so much extra-curricular help in getting through the Rickman-Hymer studies.

Thanks to her own hard work and Mr. Grant's tutelage, Karen had just earned her diploma as a certified dental assistant. This, she felt, was a great accomplishment, and she couldn't wait to start looking for her first job. It wouldn't come a minute too soon, when she found one. Karen was now sharing a tiny apartment with her kid brother Jimmy, and there was a real danger that they'd run out of money before she could find a steady job.

Still, Karen was determined to succeed. She felt grateful for the help Mr. Grant had given her, and wasn't bothered by his request to nurse on her huge tits in return for help with her schoolwork. Deep down inside, Karen had never been too confident of her academic abilities. What she always had been confident of, however, was the powerful allure of her body.
