I'm just worried that if I am in right or wrong hands.

My GF and one of her guy friends (she told me he is like a big brother to her) exchange sexts .... example like he said "I wanna FU some bitches" and she replies "get creative .. come on my tits" ...

This was the first time I snooped on her less than a year ago and when confronted ... she said it's a joke that I don't understand....

sometime later, he texted to her "I really miss your boobs...I mean you" ....

I asked her what that means and she said "that means he is just saying he miss me" ....

really? friends talk like that? particularly someone like a brother to her she told me.....

I'm so confused ....
