Naruto had always wanted a dog, and year after year he never stops asking for one. Knowing he's still too young and irresponsible to take care of one, Minato opted to rent a dog for New Year. Kushina was hesitant since she was never one for pets, but later reluctantly agrees after seeing the joy in Naruto's eyes when presented the idea.
New year finally came and Minato brings Naruto to the local pet shop where he immediately picks the largest dog in the shop. Minato does the paper works and pays for it before the pair heads back home. Just as soon as they arrive, Minato gets a call from the 3rd Hokage who tells him it's an emergency. He gives his son a hug and his wife a kiss before taking off leaving them to have lunch on their own.
Naruto had just finished his meal and is now playing with the dog. Kushina didn't want to touch the dog at first, but she couldn't help but notice how huge its phallus is despite being limp and pondered on how big it could get. Kushina immediately felt dirty but couldn't get the thought out of her head. "If only there was a way for me to measure it without making it weird" she thought as she strokes Naruto's hair as he sits on the dog. She thought about getting it an erection so she removes some of her clothing and bends in front of it as if picking up something from the ground and sure enough the dog's phallus enlarges. The dog jumps her, with Naruto still behind him, and begins ripping her clothes off.
It was at this point she knew there was no going back and before long she feels his slimy phallus making its way into her tight ass. Unbeknownst to Naruto, the very dog he is riding is riding his mom, and the more he forces the dog to move the faster it fucks his mom, giving her multiple orgasms!
Happy New Year everyone!
