Fun with a teacher

Though she could do anything with this book, Bosscake found herself completely devoid of any ideas of what else she can write, so she just wait for the end of the lesson, but when the class was over she remain seated while her classmates left the room and couple minutes later she was one on one with her teacher.

Fiercely blushing, Ms. Lemi slowly approached to her student.

"So, what do you want?" - asked Bosscake slyly grinning and moving her legs apart exposing her growing bulge, and her smile grows wider when she saw that Ms. Lemi's eyes never leaving it. - "Seeing something you like?"

"Oh, um..." - shy teacher blushed even more and her own bulge grow as well.

"Well, why don't we have some fun? Come on, strip down!" - said girl as she took off her pants and panties exposing her already hard large cock. Ms. Lemi also took off her short skirt and lacy panties and her cock also hard, it's cute little thing barely 4 inches long. Then Bosscake grabbed her teacher's wide hips and pushed her into her lap, her large dick twitched between her large buttcheeks. - "Are you ready Ms. Lemi?"

"Y-yes... And p-please call me Hanna..."

"Hanna? No, I think I'll call you... slut!" - said Kessler as she thrust her member into Hanna's pussy, the woman moaned and her cock begin leaking pre. - "Hmm, I don't want to get dirty. Let's change position!"

Bosscake reposition the teacher so she's lying over near desk with her ass up in air, and the girl don't hesitate and start fucking her. She was delighted seeing as Hanna moaned and her ass jiggled each time she hits her thighs. Soon she was lose to her limits, Bosscake leaned onto Lemi's back, cupped her large mammaries and begin moving faster and faster.

And couple minutes later Hanna loudly moaned and sprayed her ball's content on the floor and stool. And several moments later Bosscake pushed her cock as deep as possible and filled her teacher's womb with her seed.

"Well, that was good!" - said girl as she slowly pulled out her cock. And then they heard bell. - "Oh, damn i still have lessons..."

"Wait! Give this to your teacher to avoid problems." - Ms. Lemi give her student a note and Bosscake head to her next class.

"Ms. Kessler, the bell rang several minutes later!"

"Ms. Lemi told me to give you this."

"Hmm... Oh, okay, then you can take your place."

When Bosscake sat down she pulled out 'The Rulebook', after her little adventure she got several ideas, so she rewrite couple rules.

Old rule: Bosscake Kessler (the owner of 'The Rulebook') is voluptuous futanari 7 feet tall with E cups and thick dick 20 inches when hard and 12 inches soft with big balls.

Old rule: 50% of men and 50% of women are futanari with big boobs and butts and with big cock no bigger than 20 inches long. Humans are stretchy enough, so such big insertions are not painful and do not cause any damage. Their ball very productive, allowing to cum large quantities multiple times without dehydration or other damage to organism.

The moment she put down her pencil Bosscake felt as her body start growing and her clothes become uncomfortably tight, so before she burst out of her clothes she wrote new rule.

New rule: all Bosscake's current clothes adjusted to her size.

The girl sigh with relief when her clothes loosened, especially in crotch area.
