before all of this happened me and my sister have had some run ins. she has accidentally walked in on me and i had seen a lot of her because she used to fall asleep in my room or in the living room and always wore skimpy clothes. but i digress.
i walked into my room one day and started watching tv and quickly put on some porn. i took out my dick and had a long session of stroking my dick.
i got up and cleaned myself off and when i come back in i heard a noise coming from the pile of blankets on my bed.
my little sister was planning on scaring me but instead she watched me playing with myself.
a couple days pass and just the fact that she seen that was getting to me, it honestly just made me turned on that she seen. then one night as we were watching a movie she brought up how she seen me looking at naked women and she watched me jerk off.
