Laura shamefully screamed, "Ugh! I need to fuck your ass right now!"
Ms. Mounds was startled by Laura's outburst, and in the moment of confusion Laura shifted her hips on the desk, splashing even more thick precum everywhere.
"Hmm--oooughh!!" Ms. Mounds moaned, as she lost footing on the lubricant slicked floor. She fell backwards and just like that she was impaled by Laura's three-foot-long cock to the hilt. Wide-eyed, Ms. Mounds brought a hand to her belly, and felt the pulsing hot rod inside her.
"Well, since we're already here... if you insist," she simply said after a pause, and began resuming the lesson.
The whole class didn't even react much to the change of situation, more giggling, some gasps, but nothing more. Laura began thrusting her cock in and out of her fat-assed teacher, fondling her precum-covered ass with all four hands, spreading her own juices around like butter. That's when she felt something rough tickling her cock head deep inside her teacher.
Laura spread Ms. Mounds's ass-cheeks to better inspect the hole she was pumping away at. Spread 10" wide by Laura's cock, it seemed like it could stretch even more, and so Laura plunged one of her arms shoulder-deep into her teacher's hole. Feeling around for the rough object, she finally grabbed hold of a strap of some sort. Pulling the foreign object out Laura realized it was Ms. Mounds's lacey panties, which had been shoved deep by the accidental anal. She threw the precum soaked panty to the side, which made an incredibly loud slapping noise as it hit the floor.
Five more minutes passed with Laura continuously ramming her teacher's anus, her orgasm still denied until the end of class. The soft stretchy folds of her teacher's insides massaging all 36" of Laura's length sending her to even greater heights of pleasure.
Another five minutes passed. Ms. Mounds was now sporting a large belly, looking nine-months pregnant from cock and precum.
"Now, before I forget, it's time to pass out homework," Ms. Mounds said nonchalantly, all-the-while still being railed by her student. The class groaned, including Laura. She reached into her water-proof bag and pulled out a stack of paper, careful not to get them soaked with Laura's juices. She slowly walked down each aisle and handed out the sheets, being careful not to slip in precum but also still allowing Laura to pound her asshole.
*Riiiiing*
The students gathered their books and belongings. Class was over, and the students rushed out of the room to avoid what was to come.
Cum rushed out of Laura and into Ms. Mounds, her four arms bear-hugging the teacher in an orgasmic lock. Laura's eyes rolled into the back of her head as sweet release was finally allowed to her. She felt Ms. Mounds writhing, flailing even, as she was pumped full of girl-cock seed. Larger, fuller, Ms. Mounds grew.
"Take it! ALL OF IT!!!" Laura screamed in bliss. Not a single drop of cum left Ms. Mounds's insides.
"MORE!!!" Laura continued. And there was more. Impossible amounts of cum was made possible by the beeping of the remote. Two hundred pounds of cum was dumped into her teacher by the time the orgasm subsided.
Panting, Laura finally pulled her cock out of her teacher, noticing the cum was thick like molasses and so stayed neatly inside the vessel.
"S-sorry! At least I didn't get it on your hair!" Laura weakly laughed as she patted her teacher's beanbag-chair sized belly.
Ms. Mounds brushed her precum soaked hair back and glared.
"Well, you better get going onto your next class. I'll have to call the janitor to clean up after you."
Laura's cock flexed involuntarily to those words, shooting another hot glob of precum onto Ms. Mounds's face.
"Y-yeah! Don't wanna be late!"
Laura hurriedly gathered her belongings, and joyfully skipped out of the room feeling far more refreshed. Something was different about her today, but she couldn't put her finger on why.
