Saw parents having sex

Yes I have seen my parents have sex couple of times..

This happened recently while passing through their room.i saw my dad pounding mom in missionary while mom was in her bra lying on her back and giving hot moans and expressions.dad was enjoying her too much and I could see it properly.mom got on top of him in riding position and gave hot moans again.after a few mins I saw dad Cumming into mom giving hot expression and moans both of them.they fell onto bed and hugged each other..

It was a visual treat that day and saw how they enjoyed each other.
