Hold step-mommy\'s towel while she showers

Days turned to weeks as your step-mother showed no signs of planning to unlock you from your chastity cage. Instead, putting you to good use, you must now stand in the bathroom while she has her morning shower, holding her towel for her for when she gets out. "Stand there. Don't speak. Hold my towel for me and hand it to me when I tell you to." She barks. You nod and stand exactly where she points to the floor. Shooting you a wry grin, knowing how torturous this is for you, she slowly peels off her towel to reveal her naked body. You take take the towel and hold it, not daring to make eye contact. As you catch glimpses of the lathers of soap coating her breasts and trickling down her svelte figure, you curse your mind for betraying you as you feel your inaccessible member begin to swell, pressing up against the imprisoning confines of the cage. It's not your fault, it's just been so long since you had any stimulation down there now. But that was why she locked you down in the first place - your ever naughty and wandering eyes. You stand there, knees beginning to melt as you push against your chastity with each flex and throb you exert, your blue balls stirring with pent up frustration. There's no way to relieve yourself. You stare and shake as she soaps herself up in front of you, her butt lightly jiggling with each gently placed step as she slowly turns underneath the deluge of warm water. Asking to be unlocked or complaining about your punishment is an easy way to be punished more, so you say nothing. Every now and then she eyes you, a smirk crawling across her face as she knows you must be desperately squirming in your cage, but there's nothing you can do about it. There's no escape, no respite, no end in sight. She's gone from step-mommy to mistress with just the turn of a key.
