A week later...

A week has passed since being locked in chastity, the first few nights were hell, you'd wake up several times a night in pain, due to night time erections, or rather your body trying to produce night time erections but unable to since your little clitty is locked up tightly.

After the first few nights however your body got used to the chastity and now you are sleeping though the nights fine.

However now you notice that your nipples are getting very sensitive and tingly, and you think that its maybe cause your locked in chastity and that its playing with your mind so you put it out of your mind, that is until one morning you get out of the bath and while walking by the mirror you catch a glimpse of yourself in the mirror and notice that your chest appears to have little breasts now, not man breasts either but breasts of a girl going through puberty.

That evening when Samantha comes home you mention it to Samantha "Mistress, after my bath today i seen myself in the mirror and it appears like i have little breasts."

"Oh goody, its working, every morning in the smoothie I've been giving you breast growth powder i found while shopping, but i wasn't sure if it would work or not" she says.

"YOU'VE BEEN WHAT?" you yell at her.

She slaps you across the face faster then you can react, "you watch your tone of voice when talking to me sissy bitch"

"I'm sorry mistress, i just can't believe you did this to me" you say.

"Every good sissy needs breasts, real men don't want a sissy with a flat chest." she replies.

"I've also been collecting the used condoms from my boyfriend when we have sex, and I've been cooking your scrambled eggs with his cum, that's why you've noticed that they have a salty bitter taste to them, i wanted you to get accustomed to eating other mens come, and figured the best way to start would be to incorporate it into your food without you knowing about it, now take off your shirt and show me your new breasts" she commands of you, you just do as she says and take off your top, she gently starts to play with your nipples, tweaking them, and pinching them, and you inadvertently let out a soft moan, and you hear her chuckle and say "ah the sissy has sensitive nipples i see, they got nice and hard as soon as i started to play with them, this is a good thing, i'd say your boobs are sized about A-cup so far, this means we need to go on another shopping trip and buy you a new bra to go with your new boobs."
