No Sealing Jutsu Required! (Kushina x 4 Tails)

While on an undercover mission together, a Konohagakure patrol team team accidentally knocks Kushina out while under the impression she was the enemy. Thinking his mother to be critically injured or worse, Naruto unleashes a rage which sets the 9 tails' chakra lose sending everyone running away. Moments later, Kushina wakes up in time for the 4th tail to emerge from Naruto's body, and with little to no time to spare, she heads towards her son to save him from fully transforming into the demon fox. Kushina had neither wood style nor a chakra suppressing jutsu at her disposal. This left her resorting to a more "traditional" approach in suppressing a jinjuriki's chakra. With a deep breathe, she slowly removes her pants while asking Naruto to calm down. Having never seen a woman's naked body before, Naruto stops rampaging and obeys his mother's command. He walks closer to her panting and unable to control his member from erecting itself. That was a step into the door allowing Naruto to take partial control over the 9 tails' chakra, but Kushina knew it wasn't enough to fully suppress it. As Naruto stands infront of her, Kushina lays on one of the nearby tree's roots spreading her legs wide open for her son to see her pussy and ass. Naruto suddenly feels an urge exceeding the 9 tails' temptations, and with his member already erect, he penetrates his mother's ass without any hesitation! Kushina yells : "Aaahhh! Not in my ass Naruto!!" Naruto pays her no mind and pushes his member deeper into his mother's ass and all she could do is endure it. His hands grabbing her legs like vise meant she was going to be in that position until he is done! It would be hours before the chakra cloak would completely wear off, and by then Kushina's ass would be filled by her son's cum..
