When I was 15 or so, we were supposed to be going to a wedding for a relative. After I took my shower and put on some makeup, I was in my room about to get dressed when I started feeling kind of horny. I teased my nipples a little and then got on my bed and started rubbing my clit. I really started feeling it when all of a sudden my mom knocked on my door.
'You almost ready?'
I was breathing heavy and said 'yeah, in a few minutes'
'Are you masturbating?'
'Oh, sorry. Go ahead and finish, but hurry up because we need to go.'
'Ok mom, I'm almost done.'
She then walked away and I started pounding my little pussy. After I came, I threw on my dress and carried my shoes with me out to the car.
She never mentioned anything else to me about it, but I know she thinks it's ok. My mom could really be cool sometimes.
