They wanted each other and they ended up like this
Although it may not seem like it, they were you and niece, but they had such a close relationship that they actually desired each other. Each time that desire was more evident, mainly on his uncle’s side. It is no wonder since his niece was a really pretty and attractive girl. Any hug took the opportunity to touch her ass, sitting next to her he touched her legs and even tried to get closer to her breasts. He wanted to see her naked, but she was his niece after all. However, that day on the couch everything changed, he touched her like other times, but now he stopped. He began to undress her and touch her pussy, he even put his fingers in her. Then she ate his cock.
They decided to go to bed and that was where everything happened, as they both fucked like they had secretly wanted to do so many other times. When her uncle came she got dressed and left, perhaps repentant.
