I confess i ruined my submissive GFs tits for fun.
Less than two years ago when she was 19 she had really nice firm tits, and she loved to dress in a way to make her great tits stand out, fast forward to today her tits are not so firm any more and they became really saggy. I loved to stretch them whenever i had a chance and also share her with my lesbian friend who enjoyed torturing young female bodies - with her being a bit bigger girl i enjoyed watching her flatten my GFs tits by trampling them with boots, shoes, heels etc..
For now her tits feel and look like they aged 20 years in just 2 years, and she also noticed they look bit saggy even in pushup bra. Les friend who trampled GFs tits also noticed drop in outfits that highlight those tits, sometimes because they are bruised, sometimes because they hurt to much to put them in bra and sometimes because they just look saggy-sh
