I had a married couple (M54F49) rent the house next door to mine when I was 17. They were both super hot and I had a crush on them both. On more than one occasion I saw them bring another women their age there and then I would hear them all moaning and yelling i knew they were having threesomes. I would play with my pussy when i heard them. They had a bedroom window across from my bedroom window but they never had their blinds up. One time they had them up just a tiny bit and I happen to look over and they were both eating a lady's pussy. The husband made eye contact with me and I froze but he just kept licking her and looking at me. I pulled my blinds down in a sorta panic and never mentioned it. Even though i panicked that night it made me wet too. I went to college and they moved while I was there. Now I just edge thinking about how I wish that could be having them both lick me.
