I touched a Child’s breasts

When I was 14 (f) my mum and I lived with my Aunt, my Uncle and my 3 cousins (2(f); 4(f) ; 8(f). My little cousins were so obsessed with breasts and butts and would often want to see or touch mine, my mum‘s and my aunt’s they would often flaunt their chest and examine them. My aunt would play along with them and touch their chest too and my mum would do the same too. I would join in too though I was more self conscious about my own breasts so I wouldn’t let them touch or even see mine and would get super annoyed when they would try to peek in on me when showering. I used to stay home with them a lot and sometimes I would just playfully pinch their breasts randomly, the youngest would find it annoying and retaliate, the oldest found it painful because they were still buds. I wouldn’t ask to touch them but would do so randomly or when they would show them of and when they were shirtless. There was a time I wanted to pinch the oldest‘s and she refuse, so I told her I would let her touch mine if she let me touch hers, she agreed and when it came her turn, I refused. As I grew older I began to question this behaviour and stopped doing that. I feel bad looking back at it, because even though I had no sexual intent and it was normalised in the home as play. It probably wasn’t okay and just the thaught that I crossed that line with children disgusts me to the core. Im in a moral crisis and can’t even look myself in the mirror, like what was I thinking!? I deeply regret it and feel so much shame.
