我的前女友正在拍摄自己抚摸她的阴户

I've suspected my girlfriend is cheating on me with my stepdad but I never had proof until now. I filmed her masturbating on our couch while filming the whole thing. With one hand holding the phone and another fingering her pussy while occcasionally rubbing her itchy clits, she captures one hell of a view. She then sends the dirty clip to my perverted steddad
