Naruto's cock was permanently hard and he was unable to have sex with hinata because she was away, after all the time he had spent working as a shinobi he needed some relief. It just so happens that kushina trains in the forest, she chooses this location because she likes to take her clothes off when she's training. Naruto sees her with her big busty tits popping out of her chest through an open shirt, and she had nothing on the bottom except a pair of panties. Naruto's dick just couldn't take it anymore, he tells kushina about his never ending hard dick so she asks him to pull it out for an inspection. As soon as his cock was in front of her face kushina knew she wanted to suck it, despite their relationship she just couldn't help but feel like she wants it in her mouth. She tried and tried to hold out, but after naruto put his hand on the back of her head and teased her with the idea of deepthroating his cock in secret, she couldn't stop herself from sucking, she loved it
