He is so completely wrapped up by Reborn, he can't even try to get out; literally speaking.
The hitman has one arm across his chest, one across his belly, a leg between his and curled around his bottom leg (He's lying on his side), his other leg throw over the higher thigh, and his head resting on his shoulder. His eyes are open, but they're glazed – meaning that he is asleep.
This is really bad, because Lambo really has to go to the bathroom or else he is going to piss in the bed and no one is going to be happy about that.
He began a fruitless wiggle that only ended up in Reborn biting the back of his neck and a hand between his legs, cupping his manhood. He gasped and slapped both hands over his mouth, trying to be careful not to be too loud. He wants out, but he doesn't want to wake the Reborn up; that is a disaster that doesn't have to happen.
He begins tugging and pulling a bit more until he is free of one leg and one arm and then manages to slip out of the rest, the whole process taking a ridiculously long time that makes him squirm with the need he has. He has to pee; and Reborn isn't helping by grabbing his thigh and squeezing.
He waddles to the bathroom and relieves himself (it makes him so happy; he could have started a musical). He washes his hands; after a moment, he also rinses off his belly (and with another small pause in which he flushes darkly) and his butt of last night's juices. He runs a tired hand across his face, rubbing his eyes. Now more at ease, he saunters at a lazier pace back into the bedroom, stretching his arms above his head and arching his back with a pleasant groan. He trails a finger across a water drop resting on his hipbone.
He moans as he crawls back into bed, reaching a hand out to grab Reborn and be a tangle of limbs again. He mumbles when his hand comes into contact with nothing. He reaches further and – ah hah! – he grabs a hold of something; he's half-upset to feel that it is wearing clothes, but already mostly asleep again. If Reborn wants to leave, he can do so after Lambo goes back to sleep.
He becomes more upset when he manages to drag his lover to him instead of using Reborn to drag himself to him. And then he is completely confused when Reborn is small enough that he is no bigger than his chest.
He opens an eye slowly, blinking it into focus.
"Ciaossu."
"GAH! YOUNGER REBORN!" He flinches so hard, he falls off the side of the bed, dragging a blanket with him. He peeks over the side of it fearfully; for someone that just saw him naked, Reborn is keeping a calm, collected face.
… And still looks like a baby. The curse of the Arcobaleno, Lambo remembers. Only Lal, who had been an incomplete Arcobaleno, had been able to age, if he wasn't misinformed.
After a moment of staring at each other, Lambo takes a deep breath and runs a hand through his hair, shoulders slouching. "Yare, yare, this is awkward…" He glances at the Arcobaleno. "I thought the 10 years bazooka was taken away after we came back from the future?" He makes it a question; how else would younger Reborn be here?
"It was. It was accidentally found again and we decided to see if it still worked."
"You volunteered?" He is, not surprisingly, doubtful of that. Why would younger Reborn do that?
"No good Tsuna wouldn't decide fast enough."
"Ah." Lambo puts his elbows on the side of the bed and his chin into one palm. "You do realize that young Vongola and who else was there are going to catch an eye full. You weren't exactly descent when you fell asleep."
"I figured as much." Reborn cocks his head. "You're my lover." It isn't a question, but Lambo nods anyway. "Why would I sleep with a dumb cow?" He watches as Lambo chuckles amusedly.
"Had I known that, as a child, all I had to do was moon you and you would start talking to me more, I would have done it." At even eight years old, Reborn had ignored him as if he had not existed. And now, after seeing Lambo naked, he was suddenly oh-so talkative, wasn't he?
"You haven't answered my question."
Lambo smiles (unaware of how loving or warm he looks as he gazes upon younger Reborn) and ruffles a hand through his hair. "It was your idea. All I know is that it happened when I was around nine." He brushes his bottom lip with a finger, cheeks dusted with color. He sighs and stretches his shoulders lazily, relaxing again. "I suppose it wouldn't hurt to tell you that everyone is alive and well and that Byakuran has never been a bother, much less an existence, in our lives."
"And no good Tsuna broke the Acrobaleno curse, I see." Reborn gives a small smirk of pride for his formerly hopeless student.
Lambo looks from him to what is revealed of his neck, chest, and arms from above the side of the bed – he is covered in love bites, bruises, and hickeys. "Heh heh heh… Don't worry, young Reborn, you are still a complete asshole; you just happen to be a considerate lover."
"That's a comforting thought. Why hasn't Bianchi murdered you yet?"
Lambo pales and looks at Reborn with horror. "Yare, yare… I forgot all about that… It wasn't until last night that anybody else knew of our relationship… except Hibari." Now he is scared for his life… Bianchi is going to rip him a new one and then shove it full of poisoned pies.
The arcobaleno's head tilts up as if he had heard something interesting. He stands up from where he had been sitting in the middle of the bed and struts towards Lambo's head, grabbing each cheek with one tiny hand. Lambo blinks at him, confused by the other's action. "Young Reborn? -Mm!"
When the pink smoke clears, an irritated, full-grown, Reborn is sitting on the bed. On the ground is a very red, very shocked Lambo who has a hand over his lips and an impossibly wide eye. "… Your baby self kissed me… I don't know what to think about that…"
It goes an amazingly long way to calm Reborn's attitude; almost getting him to smile. He crooks a finger and Lambo crawls back onto the bed, therefore Reborn's lap. "You let another man touch you without my permission?"
The guardian sputters. "It was you, from 10 years in the past." Hands trail down his chest and drag over his hips, picking him up and wiggling his bottom over an awaiting erection. "I didn't know you got morning wood." Which is amazing, considering the fact that he had been waking up with the hitman for weeks now and had been thoroughly fucked by him every morning. "That must have been awkward when you arrived in the past – Ah HAH!" He makes that sound again, like a moan, a whine, and a gasp all in one, and throws his head back, arching his spine.
Reborn licks his upper lip before lifting Lambo back up and letting gravity have him fall onto him again. Up and down, up and down, until Lambo is bouncing of his own will and Reborn is watching with perverse pleasure. He grabs the guardian's length and begins pumping it in time with their thrusts. "Naughty cow…" He purrs, bucking his hips up to meet every downward thrust with a 'slap!'. "Beautiful, sexy, cow…"
As far as mornings go, this was one of the better ones, hands down, no competition.
Author's Note: I really want to write a fluffy chapter soon…
