By "punishing" you anytime you act like an icky boi.

You reluctantly go through your drawers which are now filled with bras, panties, knee high socks, and hose, trying to find the least girly outfit you can. Plain cotton panties, a sports bra, and a light pink socks are the best you manage, but even that is ruined by the choice of skirts and blouses. You manage to find one that covers your entire ass and chest, but it's frilly and pink and it makes you feel like a little girl, much to Mommy's delight.

"Oh you look like an innocent little angel, Barbie. Men love that. They love imaging they were the first to defile you. Of course we'll keep the truth of your slutty sissy ways our little secret." You blush imaging a man's hard hairy hands lifting up your skirt, and are embarrased to see it tenting up as your big, manly dick strains in your panties...

"Sigh, already getting into trouble, my little minx. Sissies shouldn't walk around with hardons or stand to pee or touch their clits or sit without crossing their legs or..." You zone out as the list drones on and on...

SMACK "Pay attention, Barbie! This is for your own good. Icky boi habits are hard to break, but Mommy will help you with a hard spanking, or a harder fucking if the problem persists. Now, I'm letting you keep your big clit as a reminder of what you aren't but tomorrow we start you on the sissy pills. It won't shrink your clit, but everything else will get softer and more sensitive and..." she lost you at "big clit". You are trying to will it soft, but something about the shameful situation has you humiliatingly hard...

THWACK "I see you need your first reminder." You are helpless to resist as she lifts your skirt, yanks down your panties and bends you right over your bed before plunging into your ass balls deep. You bite the sheets, desperately trying to muffle your high pitched whimpers and feminine moans, but they are too loud, too **** to be ignored...

"That's it SMACK...remember how good it feels to get THWACK fucked. Sooooo much better than trying to make SLAP Mommy cum with your pathetic SPANK clit. You know I had to think of your SMACK big bully brother to finally make THWACK spurties in your SLAP slutty SPANK sissy SMACK mouth?"

You try desperately not to spurt, but your Mommy's spanks sting so sweetly, like blissful beestings dripping with honeyed heroin. Her clit feels so awfully arousing inside you. Your "manly" ass does a remarkably convincing impersonation of a sissy cunt, milking her shaft for every tingling, trembling throb it sends reverberating through you. Her words are what really do you in. Humiliating...and heated, shameful...and seductive, degrading...and delicious. You feel your entire body seize, spasm and spurt. Your sissygasms cause you to squeeze down even harder on Mommy's cock and she fills you with gleeful, giddy gushes of her sissy spurts. For a moment every inch of you, even that manly man deep down inside you, is blissfully blank and loving every sticky, sweet sissy second...

"Well, Barbie, hopefully that reminder is all you'll need for the day. You are wearing your poor Mommy out, my lil' energizer fuck bunny."

You let her slide up your panties, the sticky mess pooling in them a shameful reminder of what awaits you everytime you try to be an icky boi. You vow to keep your head down, play the part of a sissy, and avoid any further "reminders" until you can find a way to take back your manhood.
