My cousin learns from my new wife how to have sex and I am asked to watch - A genuine amateur cuckold and whore situation

My cousin came to my house to meet my new wife and as I was leaving them alone, I asked her to teach him how to have sex. As I was walking away, I overheard my wife telling him not to worry, she would show him everything he needs to know. When I came back, I found them both naked on the couch, my wife on top of my cousin, fucking him. I sat in the corner, watching as she took the initiative to show my cousin how to fuck. I could see the excitement on their faces as she took charge, guiding him through every move. It was a sight to behold, a genuine amateur cuckold and whore situation. My wife is a natural beauty, with natural tits and a big ass that is begging to be fucked. She knows how to please a man, taking him deep inside her, fucking him hard and fast. It was a sight to behold, a true amateur anal and assfucking experience that left me breathless.
