So In Love And Yet Nothing To Talk About by rosesofenvy

Summary
After saving the world three times, you would think that Hamato Leonardo wouldn’t have a care in the world. Unfortunately, the self proclaimed face-man was always looking to subvert expectations. This particular topic was one they’d always danced around but now that they were certifiable Heroes, he figured he could spend some time worrying about it now.
As a mutant turtle teenager who was also a ninja, Hamato Leonardo never thought he would be able to meet his soulmate.
tl;dr Leo wants to find his soulmate and is willing to throw himself (and his brothers) headlong into a new mission to do so.

Summary
Leo sighed sadly. He looked up at the dark oak above him. The tree's shedding away it's first few leaves down, still plenty more to go. Leo had thought that if they were to stay here the same amount of time like the villages before, then they'd be gone by winter's arrival. "Around, three weeks hm?", he hummed to himself.
He turned to his youngest brother, Mikey, who was waving at him from afar. He had his pack slung at his shoulder, ushering him to come. It was time to enter Neo Edo.

Aka what if the Rise Crew were a part of Samurai Rabbit's universe? I wonder what chaos would ensue? Or perhaps sappy romance?
There will be some changes on the character's background to fit the narrative of Samurai Rabbit btw!

Morning Sex by Rose_spiderlily

Summary
"Leonardo planted a light kiss on his boyfriend's growing bulge under his trunks as he groped his thighs. With his right hand, he reached under the garment and lifted the hardening dick and flipped it up. With his mouth, he kept relentlessly kissing and sucking on the other's balls."
Leonardo and Usagi wake up one morning, and thoughts about last night awaken a certain sexy feeling, and one thing leads to another. They have fun :)

The alcohol keeps suggesting he take a chance on something stupid. A comment, a reaction, a touch. Leo won’t do that, of course. He’s plenty happy with Usagi being here at all.

Summary
Leo is calm, focused, disciplined and a great leader!
(no matter what his brothers say)
So why does his brain short-circuit every time a certain samurai visits?
Suddenly clumsy and emotionally off-balance, Leo finds himself spiraling and of course! Somehow his brothers notice before he does.
Desperate for clarity, he turns to the people he trusts most to help him figure out what’s wrong with him.

Or: 5 times people realize what Leo’s feeling, and the 1 time Leo finally catches up.—

Kojiro thinks Kaoru would look pretty using that mouth to beg for his cock. Even just a single ‘please’ would suffice.
A smirk spread quickly across Kojiro's face as he committed himself to getting Kaoru to beg for it next time they fucked.
Or at least ask nicely for it.Bookmarked by Mermaidtoons

Summary
Nothing says “peak boyfriend energy” like Yuuji using Megumi’s lower belly as a pillow while he excitedly theorizes that Nobara and Maki are 100% a thing now (vending machine evidence included). Megumi swimming in Yuuji’s T-shirt, no pants, fresh panties on, only hums along, running fingers through sweaty pink hair and asking just enough questions to keep Yuuji going.

Summary
For years, Yuuji has never dared to pursue Megumi romantically for many reasons: his pending execution, the genocidal curse living rent-free inside his head, and the simple (but inescapable) fact that Megumi’s adoptive guardian is, well, the strongest sorcerer in all of history. But now that Sukuna has been defeated and life has returned back to normal, there's nothing stopping Yuuji from taking the next step. At long last, he’s finally going to ask for Gojo's blessings to formally court his son.
But, little does Yuuji know, it's not Gojo who poses as the biggest threat to their blossoming relationship.
It's Megumi’s shikigami.
(Or, in order to get with Megumi, Yuuji must win the approval of his overprotective shikigami first. Fluffy shenanigans ensue.)

Originally a request on Tumblr for underwater sex, but lube doesn't work well in water, and I didn't want to hurt Leo's or Usagi's butt so I decided to add some long rambling fluff and just have them suck each other off.
