Grimm biology

"As you can see students, Grimm reproduce through sexual contact similar to us." Glynda Goodwitch said a bit louder than usual to compensate over her entire class masturbating. Her naked form leaving nothing to the imagination as her perky G-cups heaving up and down, a passive purple glow surrounding it, her semblance is quite useful in keeping her balance. She really doesn't mind though as there just enjoying her body. "Their sexual equipment is dependent on the species. Beowolf? Knot. Horse? Horsecock. And so on."

Jaune was fapping quite vigorously as he hasn't had the chance to do this since yesterday. Now he can do this whenever, wherever he wants. His team also were masturbating as well with Ren and Nora fapping to each other while Ren is writing notes and Nora is just howling in pleasure, Pyrrha was fapping to...him? Now that he thinks of it she has been sort of doing a lot of weird things around him, she dropped her pencil and bent down showing him her Ass to which he slapped them, she keeps asking if he needs help wanking and even before finding this book she was genuinely nice. Maybe Pyrrha was better than Weiss?

Jaune felt he was going to cum soon so quickly added something extra to his book.

Old Rule - Cum is an excellent source of protein and is greatly approved by the female sex. When a guy is about to cum he asked the nearest female to put his cock into their mouth and suck it.

"Pyrrha, ah, I'm about to cum!" Pyrrha immediately put her mouth around his cock and suck on it. Jaune could feel her tongue lick his shaft as he cums hard into the roof and throat of her mouth.

Everyone else also came into either a woman mouth if you're a guy or squirted into their desk if you're a girl. Professor Goodwitch also came as she had a vibrator up both her pussy and ass. "That is all for today class, for those applying to the sex-ed class tonight I will be expecting you tonight in here." sex-ed? Oh, Jaune is going to have fun with that.

At lunch...

Jaune opens his book and writes while masturbating. The entire cafeteria is filled to the brim of horny students and the occasional teacher.

Old Rule - Men and women can assist each other when one is masturbating. Whether it be Blowjobs, Titfucks or just a handjob, they are willing to help.

Jaune feels a significant increase of pleasure and looks down to see that instead of his hand it was Pyrrha giving him a Titfuck with the added bonus of her tongue licking the tip.

Old Rule - Sex products like flashlights and dildos are easy and cheap to get while also being in high quality.

He looks at team RWBY's table and sees that Ruby and Yang are using 6-inch dildos to help each other to get off, Wiess is using a dual vibrator for her pussy and ass, Blake, on the other hand, had gotten her self a very large 12-inch dildo that is similar to Jaune's cock and sees that written on it says 'Jaune Arc' Jaune looks at Blake and sees her bowtie twitch and licking her lips. Jaune gives her a smile and begins to write something for her.

New Rule - Blake Bellodana breasts will never sag and has 100% increased sensitivity in the vagina.

Jaune looks up to see Blake orgasm and her legs spasm a bit. She looks at him with a knowing look and gives him a thumbs-up, maybe he'll tell her later about the book, who knows? Maybe she'll give him some new Rules to make. Jaune laughs a little bit and then cums into Pyrrha's mouth Jaune writes something very important down.

Old Rule - Jaune Arc does not have a refractory period as well as able to produce enough cum for a 20 feet deep swimming pool in an hour.

Jaune feels his balls swell up with semen and dozes Pyrrha in gallons of hot, sticky, white cum. Her entire face and E-cup tits are covered inch by inch. She smiles and proceeds to lick it all up, one lick at a time. The rest of the cum spill unto the floor where many females were trying to scoop up the cum and put it into sport drink containers.

I look behind me to see Velvet with a sports headband on top sucking Cardin's cock like a vacuum cleaner. He holding her ears quite tightly yet very gently as well. 'Huh, looks like I helped them a bit.' Jaune thought as he writes another rule down, this time for combat.

Old Rule - Jaune Arc is skilled at using Crocea Mors in CQC

Old Rule - Jaune's sword can shoot concentrated semi aura-piercing plasma.

Now Jaune was not scientist, he knew that. But he was pretty sure that this was going to ruin someone's day. Jaune closes the book and continues to facefuck Pyrrha. He shoots another load, this time straight down into her stomach, bloating her. You know what? Another one.

New Rule - Cum and long penis can go straight through a female.

Cum runs out of Pyrrha's ass as she keeps chugging and chugging, ignoring the fact that the floor underneath the table is cum. Soon the entire cafeteria floor is covered in 2 feet of cum, with 20% of beings Jaune's.
