Headmistress' Favorite Sport Part 4

Both she and Yvonne were sobbing hysterically, tears streaming down their faces. Headmistress bent down and brought her face close to Denise's, holding her chin in a vice grip and looking her straight into her eyes as she asked Denise: "I trust that you have learned your lesson? I trust that you will now treat teachers with the proper respect?" Denise tried to nod vigorously as she made sound of confirmation behind her gag. Headmistress looked at her again and said with an exaggerated sad look on her face: "I think not. I know sluts like you. You are always insincere and the lesson needs to be hammered home." Denise tried to shake her head, to plead for Headmistress please not to hurt her anymore, but that was of course out of the question. Headmistress stood up and with the toe of her right boot stepped down on Denise's left testicle, gradually increasing the pressure. Denise's world exploded in pain and she screamed; the tendons in her neck standing out as her head grew red and she ran out of air and her scream became silent.

Then Headmistress took her foot away and after a little while Denise had caught her breath again as she sobbed in pain. As soon as Denise had gotten tiny measure of control over herself, Headmistress did the same thing to her right testicle. When Headmistress took her foot away Denise was just about to loose consciousness from the pain. Before leaving Denise to subject the absolutely terrified Yvonne to the same treatment, Headmistress had a parting shot. She stepped back and delivered a brutal kick with her pointy boot to Denise's crotch. Denise had no air to scream but she tried anyway before she tried to lean back on her hands and get a measure of rest while she cried. It turned out that Headmistress had made their bindings so that it wasn't possible. Leaning back to touch the ground put so great a strain on her hips by twisting them, that she had to try and maintain her "normal" strained position.

Next to her Yvonne underwent the same brutal treatment: first the whipping, then Headmistress stepping on either testicle before finally finishing by kicking her in the groin.
