3weeks
After the first week my nipples began changing and growing and became irregular in appearance looking as if they were melting into the normal skin aswell as begin sensitized with a nodule behind.
After the second week I'd noticed that I had sensation in the whole region not just the nipple.
In the third week... I had a shower and the head shower at the place I was staying would occasionally fall apart and you'd have to reassemble it... this happened. So I was on my knees picking up the bits and because I had my arms out streched infront of me in narrow profile. I looked down initally at the shower head but also saw on my chest two small boobs.
It's just a shame that after the 4th month my breasts stopped growing at bee-sting size However my nipples just keep growing and growing >_< I have almost no boobs but have to wear a bra because of how much my nipples stick out. cut a golf ball in half and stretch it out into a dome shape you have an idea of how big they are now. ¬.¬
argh body fail

(They look nicer if I can make my nipples erect otherwise my boobs are just two giant nipples.
