It might be possible to do a deep chest piercing on some women. I've had trouble finding any information at all relating to this piercing on female anatomy so I couldn't say how plausible it is.... but it's certainly possible on men.

Breast skewering goes deeper than just on surface. It can pierce through the whole breast. Psycho Cyborgs did it on a show. So I wondered if a guy said some woman had a permanent piercing through the breasts, if such thing is possible at all.

I suppose it would have to be done surgically to be permanent, but even then, I am pretty much unsure it is even possible. But since there are such bizarre things like piercings through a muscle, I am still not convinced it's impossible and just out of curiosity, I want to know if such thing was ever done.

Just remember, muscles don't regenerate like skin. And, muscles are stringy, somewhat like tendons, but smaller and packed closer together. If you tare your muscle it may not heal correctly and could cause you to lose functionality in parts of your body. Obviously it would depend on the location and damage done. Just saying. Keep that in mind.

Originally posted by snake07 I've read (on one forum) of some "extreme piercing show" where a dancer reportedly had a breast piercings 28 mm in diameter. The guy also said she allowed him to lube his finger and put them into those holes where his fingers met in the middle. Well, I suppose the guy was just a big liar, but I am still curious.

I have also had this experience, at a sex show in Berlin. She did several sessions for the show and started by wearing some "patches" over the holes, then some large rings about 10" diameter and probably not more than 3/8", the final stint she was wearing a massive barbell right through both breasts and a ball in the middle between the breasts all the balls were about 2" diameter.
When the show was over my girlfriend said she fancied the breast piercing so we asked if it was possible to meet the dancer, she came out and had a drink with us. After a long chat which I guessed convinced her we were serious we went to her dressing room (well cupboard) to have a proper chat and look, she removed the tubes which she was wearing to keep them open, we both had the finger experience, in my case one finger just about went right through. She has a big box of items to wear through her breasts made of all sorts of materials, she demonstrated a number of them including a toy snake and a 2 foot long double ended green dildo which looked terriffic, the barbell was a tube about 1" and the 2 balls were solid steel, the middle ball was hollow but she could not wear it for too long as the whole thing weighed several pounds.
She had had the piercings for over 10 years and reckoned they took 2 years to fully heal, they were originally punched at 10mm, (although I must be honest and admit I don't understand how something that thick/long can be punched) and still stretching them. When we had finished she replaced the tubes which were really more like a sheet of rolled up plastic which sort of unrolled when in position. One of her targets was to be able have sex in them.
