With each passionate thrust of his hips, Naruto came to the notion that he could speak of this to Sasuke. That he had intimate relations with his mother. That wouldn't go well at all. Just imagine telling your teammate, friend, and rival that you fucked his mom. That would not be a fun conversation to have with someone. This would be a secret that Naruto would have to carry with him to his grave. Both he and Makoto would have. They were too lost in their lovemaking to care about anything else or the taboo decision they just made.
It was just them two and no one else. Free from judgment. Free to enact their sexual desires for each other without prying eyes. Makoto is aware that she has just cheated on her husband with her son's teammate. However, the notion doesn't bother her. Naruto was the most passionate lover she had ever had. And she wouldn't give up this new connection between them. All she could do was moan and take the young stallion's sweet dick that was made to conquer milf pussy. And conquered it has. She has never felt so utterly dominated before. To be taken so roughly... and dominatedly, was a dream fuck. An erotic fiction out of a comic book. She thought to herself, but it was very real. She could never even look her best friend in the eye ever again, and say, "I fucked your son!" She would undoubtedly lose a friendship over that. But that doesn't scare her. What does is the connection her and Naruto have for each other.
Each movement he did was a reminder that he fell into the blissful rabbit hole. However, that didn't matter to him. He was only focusing on the pleasure he was experiencing with the Uchiha MILF. I mean, Makoto was too much of a milf not to fuck. I think anyone would have hit it, I'm sorry. The sounds of pleasure and activities could be heard within the house. Thankfully, Fugaku wasn't home. He was too busy catering to the affairs of the Uchiha clan. He didn't have a clue that his wife was fucking around behind his back. That she was being a naughty MILF for some young blondie.
