I got caught by my big bro a lot of times. It almost never sucks to have a big brother catch you. Lucky for me!
The first time, I was 8. I was in my room, I forgot to lock the door, and he went in because he forgot his phone in there. He said he was going to talk to me about masturbation when I was 11, but he was to late.
Now he just says, "again?!" whenever he catches me.
