She would love to

“ I would love to become your Girlfriend Kiba!.” Kushina turned her head and brought Kiba in for a kiss. The two fiercely make out as Naruto could do nothing but watch, while his mother and his former friend swap saliva right in front of them. The frustration and shame bubbling inside him growing as he saw Kiba’s tongue slip into his mothers mouth, with her groaning in pleasure as he did so. The two continuing to kiss for an entire minute before separating With a Tell string of saliva connecting the two of them.

“ I can’t believe how lucky I’ve gotten. Not only do I have a hot girlfriend, but I also get to pay back Naruto for the humiliation I faced during the chunin exams.” Kiba gloated, both his hands now molding his girlfriend's large breast, relishing in the way Naruto could do nothing but watch as he made his mother moan from his touch, letting him play with her as he pleased, especially now that they were a couple. He couldn’t imagine better payback than this, and he was only just getting started.

“ Hearing that makes me so happy! Kiba. How about we go out and buy some new clothes and a collar for me to wear, I’m sure you’ll want Naruto to see a reminder of who's girlfriend I am!.” Kushina recommended, knowing that a tangible representation of her new relationship with Kiba, would remind Naruto of the humiliation of his own mother going out with his friend. To know the mother he loved would become the lover of someone who he once trusted. It was the ultimate punishment, a constant reminder for his inadequacy as a man.

“ Of course, if you’re going to be my girlfriend then we need to get you a new wardrobe. The housewife look is nice, but I’m sure we can get you something sexier. Tell me which shop shall we visit first?, the dog shop for a customized collar, the cosplay shop for various skimpy outfits, or the sex shop to buy all the toys you’ll be pleasured with. We’ll even take the loser to watch as you put on the collar and try on all the clothes you’ll be getting!, and picking out the sex toys you want used on you.”
