Janet fights the inevitable.

Janet continued to struggle in Michelle's grip as the girl she had intended as her pet continued to ride the feeldoe and grind their bodies together. Michelle's actions ground the shaft of the toy that was within her, the effect both arousing and shameful to Janet. With her arms now pinioned tightly behind her by the sleeve her superior muscles that she had worked so hard in the gym to build up were negated. Her shoulders, pulled back by the sleeve's harness thrust out her chest. Her overly large firm breasts on her slim torso, already tightly constrained by the cinched corset were further pushed together and upwards threatening to spill out from their confinement.

William, seeing Michelle's tight grip upon the would be domme and the futility of the latter's struggling felt relaxed. He let the leash drop and backed off so he could enjoy the spectacle whilst he leisurely undressed. He admired Janet's body, despite the tiny body his former rival John had become trapped in a strict regimen of gym workouts had transformed it that of a hardbodied athlete with surprising strength and endurance for it's size. He noted the small rounded taut globes of Janet's ass flexing repeatedly and smiled as he realised the failed dominatrix was still attempting to fight against her predicament and sought to expel the buttplug by squeezing it out of her rectum.

Gasping with the effort Janet concentrated her efforts, her rectal muscles squeezing and pushing as she sought to dislodge the plug from her sphincter.It's insertion was more humiliating to her even than that of the feeldoe. That another dominant man, as she still struggled to think of herself had penetrated her ass even with a toy was demeaning in the ****. Though her squeezing muscles could cause the steel plug to be pushed outwards, her tight sphinctal ring worked against her objective. She had never allowed herself to experiment with anal insertions either before or after her transformation and her virgin asshole was just too tight for her to **** open to pass the widest point of the plug with her hands.

"Hmmm, I don't think that will work Janet." William commented with amusement after watching a minute or two of Janet's hard buttocks flexing and the black enamelled base of the plug pushing only partway out before it's lozenge shape drew it back in. "If you'd had anal a few times then perhaps your little asshole would be relaxed enough to succeed, but for the moment it is just too tight. Your efforts are commendable although the end effect is simply to buttfuck yourself which is a pleasure I would prefer for myself."

Janet let out a moan. Despite trying to mentally block the sensations being wrought upon her body the twin effects of the feeldoe grinding in her vagina and the plug stretching and moving in her butt were too intense to ignore. Though she had never been penetrated as such in her female form she had often been licked out by subs or jilled herself to orgasm and knew every sign of her body was that she was inexorably being driven to the point of arousal at which she would climax whether she wished it or not.

Janet nodded, acknowledging the truth of William's observation. "Damn you William." She gasped. "Tell me now that you have me at your mercy was it you? Were you the one that dosed me with XChange that first time and was it you that informed the club?"
