Walking out of her room, Kushina Uzumaki wrinkled her nose a bit at the smell of the natural hot spring. It was easy to understand why the fake ones at the club were so popular these days, not many people really liked that rotten egg smell. Once you got used to it though, it wasn’t so bad, and the other minerals in the water were great for the skin, to say nothing about how the constant temperature was just so relaxing!
She smiled as she walked naked out into the open air, swaying her hips slightly as she looked back at her grandson, Boruto, as he walked out nervously. “It’s alright,” she told him with a smile, “Your father and the others won’t be back for a few hours at least. This town has a nice festival this time of year; it’ll keep them occupied, so we’ll have the spring all to ourselves.”
She had come to the resort with her son and his family for a brief getaway weekend. They had all spent the day walking around town and taking in the sights. She loved the way Himawari was in awe of everything, it was so adorable. But she really wanted the chance to be alone with Boruto (who seemed less thrilled to be out here). She had decided to take Ino’s advice and just go with it.
“Are you sure this is okay, think the old man suspects anything?” Boruto asked nervously as he walked out of his room. The resort was set up so several rooms all shared one hot spring pool, allowing a modicum of privacy. This bath was linked to three rooms, hers, and the two shared by her son and his family. So no one would be bothering them at all.
“Nah, come on.” she said, beckoning him closer as she waded into the warm water, shaking her ass for him as she moved. “I want to spend more quality time with my new grandson~”
She smiled as he visibly gulped and discarded the single towel he wore around his waist. His huge dick was already more than three quarters hard, and Kushina couldn’t help but lick her lips at the sight as she moved to one of the benches carved into the pools side. Boruto followed her as she sat down, her heavy tits still just above the water’s surface. She smiled as she watched his cock getting harder already and moved her hands to pour some of the water over her nipples. It felt hot at first, but rapidly cooled, making her nipples stiffen.
“I’m all yours.” she said with a purr.
She giggled as he shyly leaned forward, grabbing her heavy tits in his hands and gripping them tight, his fingers sinking deep into the soft flesh. The redhead then moaned as he pulled one fat tit to his mouth, wrapping his lips around her nipple. ‘Boy’s and boobs,’ she thought to herself as she reached her own hands into the water, grabbing his long and thick cock. She loved the way it felt in her hands as she stroked his length slowly.
“Mmmmmh, ‘Ba-shan…” he groaned around her nipple, swirling his tongue around the stiff nub as she gripped his cock in both hands. She began pumping them up and down his huge length faster, her pussy already aching with need as she shifted in her seat and spread her legs wide.
Pouting, Kushina lifted one hand out of the water and chopped Boruto over the head, “I said call me Ku-chan!” she said dourly.
“Sorry… Ku-chan.” Boruto said, rubbing at the tiny lump forming on top of his head.
She smiled, “Mmmmh, kiss me…” she breathed as she moved one hand to cup his heavy balls, gently rolling them around with her fingers. Boruto moved to press his mouth to hers. Her tongue slid against his, sucking it back into her mouth as she guided his cock inside her slowly.
“Mmmmmmmh… Yesshh… Sho thiiiick…” she moaned into his mouth as half his length pushed inside. Her legs moved to wrap around his waist, pulling his dick all the way inside. She could feel her belly stretching around his length and moaned even louder.
“Mmmmmh, Ku-chan, you feel so good inside dattebasa… much tighter than Hanabi-nee-chan” Boruto groaned as he began thrusting against her, the water sloshing around them. His hand moved to grab her tits again, kneading them roughly as he kissed her harder.
“Yeshhh, more… Fuck me harder…” Kushina moaned, pushing herself up on her hands slightly so she could roll her hips against Boruto’s thrusts. Her tongue slipped and slided against his as she shuddered in pleasure. She loved the feel of his cock slamming into her over and over, so long and thick, filling her completely. The redhead couldn’t decide what turned her on more, the size of his cock, or the forbiddeness of their affair.
As her body shuddered in ecstasy, Kushina decided she didn’t care as she tightened her legs around his waist. Using a mix of her own strength and the buoyancy of the water, Kushina whirled Boruto around onto the bench and shifted to straddle his lap. She rested her hands on his shoulders as she bounced herself up and down, moaning louder as she began cumming again and again.
“Mmmmmmh, Boruto-kun, don’t hold back, you… AHH FUUUUCK!!!… You can… Cum inside!!” she panted.
“Ku-chan, I…” he began, but she cut him off with another kiss, sucking hard on his tongue as she lowered herself all the way down on his length and clenched her inner muscles. She smiled inwardly as she felt his cock throbbing inside her as he came.
“MMMMMMMMMHHHH!!!!” Kushina moaned as she broke the kiss and slowly rocked her hips back and forth in his lap, stirring his cock around inside herself.
“Mmmh fuck! that was great…” Kushina smiled, and then to her surprise noticed that her rocking and grinding slowly reinvigorated Boruto’s erection .
‘What stamina! youths these days are quite something.‘ she thought with a grin.
