I find this weird... but idk... so I was out shopping with my boyfriend, his mom and his sister.

His sister went off for an hour with her friends, me my bf and his mom were having lunch. His mom told us that his sister had started her periods and was developing quickly... as I was saying she's growing up so quick.

Anyhow, when we met back up with his sis, his mom told me and my boyfriend that she refuses to wear a bra... so my boyfriend, knowing she was developed... not a kid you know... RIGHT after finding out there's no bra there flicked her titty.

I was a bit shocked... it creeped me a little. Would it with anyone else?

Edit: he was 22 at the time and she was 12
