Girls, Danced with my sisters friend at the club and now my sisters mad at her?

[Anonymous]

I went out to a bar with my sister and her friends, I’m 21 and they are 23-24.

one of her friends is really cute and we were dancing a bit and she started getting really flirting and rubbing her butt on my crotch which made me super hard.

my sister saw and got really mad at both of us.

why do you think she got mad?

Because you're trying to have sex with her friend? Is this really a mystery to you?

I think she was upset I got a boner, is that so bad
