This is really disturbing, but lets just say the weekend just gone, my sister turned 15 and we had a bit of a party

After everyone left, it was just me and her (I'm 23 myself)

My sister got really drunk and started doing dirty things.

First my sisters was taking her panties off and had a short skirt on and was opening her legs really wide and
then my sister was showing her vagina and breasts off to me.

and I've tried to block it out my mind but I can't believe i'm sayig this about my younger sister..
She had a reallllyyy pretty vagina.. and really perfect breasts. just the best looking i've ever seen....................................…

Now I feel realllly weird like they can't come out my mind..... this is 100% true by the way not a lie

what i should do?

My little niece in my house, what do I do /jp/? What I've done so far: Sniffed hair, poked ass with penis, rubbed ass with penis. She hasn't noticed, she was playing her DS.
