Video of husband and wife sex secretly watched

It was night time. Window of my neighbor's house was open. I went closer and looked inside and found husband and wife having sexual intercourse while naked. Wife was lying on the mat and husband was fucking her. Wife had spread both her thighs. Seeing that sight, my penis became erect. Seeing their sex, I started masturbating. Now I always see the window open at night. I would understand what was going on inside. I would go to watch live sex.
