She makes him an offer

Miss Clema was beyond grinding down onto Vince's fat ass as she pushed more and more against him. The grinding and bumping was more than he could take! He was trying to keep his mind clear but it was impossible for him to do anything but grind his cock back against the beautiful red head teacher! But as soon as it began it seemed to come to an end as Miss Clema stood up. Fully straightening out of her dress as she walked to the front of the class. Her heavy childbearing hips swaying left and right as she began to lecture on the topic at hand, breaking up the groups as Vince flushed. He was sure that she was going to do more than just grind on him, but it seemed the futa was content to end it with just that. Feeling a bit disheartened by that Vince sighed and decided that it was time to just chill out and clear his head! He was trying to beat the stereotype that all males were just looking to get knocked up by thick futa dick anyway! He focused on her teachings and lessons before the class ended wonderfully early. His tiny dick still hard as a rock as he sighed and put away his stuff. On his way out Miss Clema waved him to the side as he gulped praying she did not reprimand him for what happened as she gave him a warm smile.
"Vince... I would like to say that I did not expect you to be so forward." She said as snickers came behind him as class ended and the rest of the students including the beautiful Planta left. He froze as he felt his mouth go dry as a desert as he shivered.
"I... I don't know what to say..."
"Well I do. I would like to make you an offer."
"W-what kind of offer?"
"Well as you know I'm a futa with needs and you have already aced my class. So let's make a deal. I need a desk boy."
"A desk boy?"
"A simple deal. You will be under my desk sucking my cock for the rest of the semester. You will be given full school credit and will get a full letter of recommendation from me to any college of your choice. And you will also get the experience of sucking a futa dick well and trust me if you ever want your dick touched by a futa you will want to know how to please one. So tell me Vince do you want to take me up on this once in a lifetime offer?"
