Welcome back to my story. First off, I want to give credit to Fox King JM's story "The Boys vs. The World vs. The Universe" for inspiring this story.

Naruto and Kushina looked outside their windows when they saw the green flash of light and heard the noise of thunder. Outside were a handful of people, some were familiar faces they knew, others were entirely new.

There were their fellow futa friends Hinata, Tsunade, Mikoto, Kurenai, and Anko. Tsunade was fully naked, her massive H-cup breasts, colossal ass, thick full bush, chubby tummy, thicc thighs, and sixteen-inch foreskin-covered cock on full display while the rest of the girls were either in their underwear or bikinis.

Standing next to them was a handsome and suave man in a gold shirt and black pants holding a ray gun and he was accompanied by a gruff brunette man in a white dress shirt, a black leather vest, black pants, and cowboy boots.

Tsunade shouted out "Hey Naruto! You and your mom should come out here right now! Don't even bother getting dressed. You're coming along with us. Where we're going, you won't need clothes. We'll explain everything!"

"Umm, okay...Kaa-chan, you want to go with Tsunade and her friends?"

"Sure thing, Sochi. Let's head on out!"

Without further preparation, Kushina ran outside totally bare-ass naked, her dick flopping and her boobs and butt jiggling freely as she went out to greet Tsunade, Hinata, and the rest, her nude blonde son following close behind.

"Tsunade, it's so good to meet you again. I was going to invite you, Hinata, Anko, and the rest over to my place tomorrow for a party but it looks like the party's come to us! Who are your two friends?"

Tsunade turned to the two men and said "Introduce yourselves, my dudes."

The man with the gold shirt shook Naruto's hand and then kissed Kushina's hand.

"I'm the enterprising Captain James Tiberius Kirk, affiliated with the Federation's Starfleet. I was sent on a mission across the multiverse and I wanted to recruit some help. You and your son are crucial to the mission, as are your futa lady friends."

"Nice to meet you, Captain Kirk. I'm so glad you invited me and my son to come along for our journey. I'd love to come with you if Naruto's cool with it."

"I'm down for whatever, mom. Believe it!"

"Awesome!"

The brown-haired man in the vest then moseyed his way over to the nude mom and son and shook both of their hands.

"Name's Han Solo. I'm the captain of the Millennium Falcon. It's a good smuggler ship that can run the Forty in 2.2 seconds but unfortunately, I lost it in a poker game to some dick named Cooler. So I'm riding with Captain Kirk and these fine sexy futa women. It's good to meet you two."

"Pleasure to meet you too, Mr. Solo. Let's ride!"

Soon, all the futa women stood close together alongside Naruto, Captain Kirk, and Han before the enterprising star captain entered some numbers into a device on his wrist and they all disappeared in a green flash of light, only to find themselves in a luxurious large room that was decorated with all sorts of beautiful manga artwork, some of it erotic in nature and the room had a massive soft comfy bed with a large bathroom area next door. The bathroom had a large walk-in shower with multiple shower heads, there was also the usual sinks and toilet stalls as well as a small locker-room area and on the other corner, a swimming pool, a hot tub, and a bath tub.

"We're now officially on the most luxurious ship in the entire multiverse. Welcome aboard the HMS Colossus, the pride and joy of the White Star Line. Now, this ship is clothing optional for the passenger guests. Not only are nudity and public displays of affection permitted, but they are encouraged. Even things like having sex or masturbating out in the open are permitted in most areas unless specifically marked otherwise. Han and I are going to the ship's bridge to work with the crew. You all can feel free to get comfortable, have fun and mingle with each other and the other passengers of the ship."

As Captain Kirk and Solo walked out of the room and into the halls, Tsunade and Kushina sat down on the soft bed alongside Naruto while Hinata, Mikoto, Anko, and Kurenai all got fully naked, their beautiful bodies in full view. Each of them were futanari women with large breasts, big butts, broad hips, thick thighs, full bushes, chubby physiques, and large dicks, exactly the kind of women Naruto likes.

Tsunade gently kissed Naruto's forehead and began to stroke his dick to full hardness as the blonde teen sat on her lap, her own penis was now rock hard to the point it was throbbing and nestled between his soft round butt cheeks.

"You want me to fuck you?"

"Yes, ma'am! Fuck my ass hard. I just got done fucking my mom just before you got here, and now I'm in the mood to bottom for now."

"Hehe, with pleasure, sweetie."

Soon, Tsunade gently slipped her cock into Naruto's tight butt, making him scream loudly and moan lustfully in a strange mix of agonizing pain and ecstatic pleasure.

"Your cock is so big in my ass! A lot bigger than I remember. It's been so long since another futa has fucked me."

"Fuck, your ass is so tight! Feels so fucking good around my cock! Ahhh!"

Giving Naruto a few minutes to adjust to the massive penis inside his butt, Tsunade took deep breaths while Mikoto and Hinata kissed and caressed him to comfort him and Kushina leaned down to give him a blowjob to help him relax and feel very good. Naruto was so overwhelmed with sensory stimulation that he came a lot earlier than normal, blowing his load into his mom's awaiting mouth, the redheaded futa swallowing all of his cum with glee.

Tsunade still hadn't met her own needs, so she then began to fuck Naruto as soon as his climax died down and Kushina was finished swallowing his seed, the older blonde thrusting upward and hammering at his sweet spot as she went at it like there was no tomorrow. She hadn't jerked off or had sex in over three weeks and she really wanted to blast her load. Since Naruto came already, she decided to just give it all she got and pound away at his butt until she finally nutted inside him. Leaning in as she grunted and groaned, Tsunade kept at it, making Naruto scream and moan until she felt her own orgasm draw near.

"I'm gonna cum! I'm gonna cum inside you!"

"Do it, Tsunade! I want you to nut inside my ass! Ahh, fuck!"

Without any more warning than that, Tsunade's balls tightened and her cock twitched before she had a truly mind-blowing orgasm, the BBW futa queen nutting for two whole minutes as she filled Naruto's butt with her hot white spunk. As soon as her loads fully died down, the older blonde slowly and gently pulled out of her teen male lover, rolling over onto her back while Naruto was still laying on his stomach, panting. Tsunade's cum was slightly oozing out of Naruto's anus and she even blasted one last small load onto his buttocks as she was pulling out.

The two lovers were tired as fuck from their activities and both of them passed out and fell asleep, Kushina gently kissing both of them and pulling the comfy sheets and blankets over the two sleeping lovers while she decided to head out alongside Mikoto and Kurenai.

"Hinata, Anko! Either of you want to join us three MILF's and explore the ship?"

"Sure, I'll go! I love hanging out with you, Kushina. I mean, I've got something I want to tell you, since you're Naruto's mom. It's a surprise for him." replied Hinata.

"Eh, I'll just stay here and relax while Tsunade and your son get some rest. Probably gonna take a shower and then explore on my own if I'm feeling up for it."

"Works for us. We'll see y'all in a bit."

Kushina, Mikoto, Kurenai, and Hinata strolled out of the shared bedroom, intentionally walking in a way that made their naked butts swaying as they headed on out.
