Headmistress' Favorite Sport Part 4

This was confirmed one day as Headmistress entered her class one day to give her a message. Mistress Erica had fallen to her knees instantly, kissing Headmistress Kaltenbrunner's shoes. The Headmistress had delivered her message and turned to leave when she thought the better of it and returned. She had then ordered Erica to drop her skirt and it was here that the class found out that she was shemale and why she had never asked any of them to perform any sexual favors for them. Underneath her dark blue leather skirt Erica's member was imprisoned in a chastity tube. They saw this as Headmistress released the strap that held her genitals up between her legs after removing her panties and the sopping wet sanitary napkin they held. First Headmistress whipped Erica's ass, demanding that she count out the blows and thanking her after each blow for: "Teaching such a useless sissy-shit proper posture and discipline." She finished the session by rolling up her sleeve, putting on a rubber glove, lubing up her hand and ramming as far up Mistress Erica's ass as it would go.

And that was quite far, all the way up to Headmistress' elbow. While pumping it in and out of Erica's ass to the sound of her out of breath screams, Headmistress amused herself by squeezing Erica's balls viciously. After half an hour of this treatment Headmistress removed her arm and Erica collapsed on the floor, thanking Headmistress for the lesson. As Headmistress finished by letting Erica licking her arm clean from shit neither Denise and Yvonne could control themselves any longer and came both massaging their now quite respectable tits as they emitted little orgasmic screams. Their behavior eluded the spent Erica, but it did certainly not elude Headmistress von Kaltenbrunner. She looked sharply at the two oversexed sissies and said: "Send these two to my quarters after class Erica." Erica croaked: "Headmistress, yes, Headmistress." Headmistress von Kaltenbrunner looked at the sissy licking shit off her arm and spat: "Get cracking you useless turd! These slaves are in need of training and what do you do? You lie around loafing.
