Not all of them

As Amelia navigated towards the showers, the noises of showerheads, running water, and even giggling could be heard. Rolling her eyes out, she figured that there's safety in numbers after all and it was her fault that they returned late. And so, as she stripped nude in the locker room, unraveling her bun, and finally stored her clothes in a staff's locker, she walked towards the bright embrace of the open shower space that illuminated her face and perky 36 D-cups alongside her athletic body before she too was welcomed by her students as well.

"Girls, hope you had a fun day today." She remarked and several (homogenous) responses promptly returned to her. Choosing a showerhead somewhere in the corner of the room, Amelia first allowed the water to run through her body as to allow for an easier time in applying soap around her body. Ignoring the rest of the room with whatever they were giggling about, Amelia soon began lathering her body from neck to toe - though noticed that the room got eerily quiet as she bent over for her lower body parts.

Then she felt a small slap to her cheeks to which she immediately recoiled from, turning around to see a Warrior Princess by the name of Ahura Anliem whose cheeks seemed to turn red - something very unnatural in her realm's culture, - before she reaching for the shower's knob.

"My apologies teacher, I'm a bit of a hurry for a shower." Then with a twist, she too was washed down. Impressed by the manners of someone whose culture consisted of primary warfare, Amelia observed the warrior shampoo her long brunette hair before looking down towards her tanned and toned body until noticing that the futanari had a stiffening boner. The teacher looked away as she witnessed it jolt all of a sudden and returned to rinse away the foam off of her.

Then she noticed something else suspicious with her student, located on her face was a smirk of some kind which too was rare from this student of hers, - whose fierce outbursts once scared a good handful of her classmates - and her suspicions rose when a lowly giggle was heard trying to hide under the noise of the showers. Investigation on this problem was postponed as the feeling of something sharp but gelatinous in a way came from behind.

Her neck immediately sought to find the offending person, only to find an elven student by the name of Alora Ginwide who had a grin stamped on her face. Before Amelia could protest and demand an answer, her breasts were groped by the woman behind her, another offense. A hand departed away from Amelia's jugs as it made way down to her womanhood which she began to massage while two fingers rubbed on the teacher's sharp nipples much to the distress of the latter.

Soon Amelia noticed that some of the showerheads were being turned off as she was surrounded by her pupils of all races and all expressions of glee and lust on their faces.

"What's the meaning of all of this!" The teacher demanded as a silent yelp escaped her lips afterward, then another student came forwards, a snow fairy and another futanari by the name of Ella Konen.

"Teacher, we've noticed that after each activity you're as tired as an ox. We believe that it's time for you to relax for a bit and as thanks for being such a cheerful and impactful teacher, this shall be our way of thanks to you from now on.

"Through a physical show of ****." She leaned in to kiss her teacher but merely lasted only for a second before Ella slid away, "Just the way she taught us, ladies. One by one until the enemy's whittled down to the last woman!"

Ella disappeared in a massive crowd of pupils awaiting a turn with their teacher. Amelia's pupil darted at every corner that her eyes permitted only to see herself trapped. With no other option, a hand of her own slipped downwards to her crotch and met the fingers of the elf, tracing her womanhood in a slow rotating manner as Alora laid another kiss on the teacher, this time on her cheeks.
