A happy couple who moved to a certain residential area. They may be newlyweds, as they don't have any children yet. I can see into their bedroom from my room next door. The sound of their lovemaking that I could occasionally hear was stirring up my fantasies. One day, I witnessed the wife masturbating through the gap in the bedroom curtains. Her fingers were so intense that I couldn't imagine her being a quiet wife. I quickly took out my cell phone and filmed her masturbating. I was worried, but I couldn't resist my excitement, so I hurried over to her. I rang the doorbell, entered the room, and locked the door. When I showed her the video, she looked suspicious of my visit, and her face clouded over in an instant. When I touched her body, she weakly resisted. I took off her clothes and ran my fingers between her legs, and she was already wet, probably from the masturbation I had just done. I stroked my erect and hard penis. She stared at it while playing with her private parts. I presented my penis in front of her, slowly opened her mouth, and stuffed it into her mouth. I made her stand and inserted it from behind, and she began to moan with delight as she reached orgasm.
