This is not as steamy as I'd hoped, but these boys have something of a mind of their own. Enjoy!

"Robin," Bertrand murmured, "are you asleep?"
"Mmm, no. You?" The vampire couldn't help but chuckle at that.
"Incredibly, no." He paused a moment before continuing. "Nervous about tomorrow?"
"A bit." His breather huffed. "Not the driving."
"I didn't mean the driving, Bran."
"Can we just... not talk about it?" Bertrand nodded, pulling Robin closer, settling ready to sleep. Robin, however, seemed less keen on this idea. "Mm, you alright tonight?"
"I don't plan to lock you in a cupboard again, if that's what you-"
"It's not what I mean. I just... are you OK?" Bertrand pressed a gentle, lingering kiss to his lover's cheek.
"I'm fine. I'll be... yeah, I'm alright."

Robin wriggled free of his arms, though, and turned to face him.
"He's dead, Bertrand. Long ago. You beat him." He shook his head; in the end, his sire had won. He'd got between him and Robin, he'd made him a ruined shell of what he might have been. "And even if he wasn't," Robin was continuing, "you know I can look after myself, right?"
"You're a-"
"-breather, yes, trained by the best vampire tutor ever and kept very well exercised to boot." He smirked, but Bertrand didn't return it.
"Breathers are-"
"Don't even say it." Robin's voice was firmer than he'd ever heard it. "Don't you dare believe what he said to you, Bertrand. You couldn't break me if you tried. And you wouldn't try."
"Ro-"
"No, Bertrand. He can't hurt you any more, I won't let him. And he can't make you hurt me."
"He's dead."
"His memory isn't. But I'll protect you, B, I won't let anything bad happen to you."

There was silence for a while before Bertrand spoke.
"Robin?" The boy opened his eyes. "Could you... just talk to me for a bit?"
"About what?"
"Anything. Just... I need to hear your voice. It... you make me feel safe." Robin snuggled up against him and squeezed his hand.
"Remember that time we went to my parents' and nearly got busted?" Bertrand grimaced, but Robin laughed. "Ah, if you're pulling that face, you can't be remembering it right."
"Go on, then. How should I be remembering it?" Somehow, Bertrand suspected that this wasn't going to help him sleep.

"Robin." He froze, hand still resting far-from-innocently on Bertrand's thigh.
"What?"
"We can't do this here. Your parents are right-"
"-Downstairs, yes. I'm sure you can be quiet."
"Fog, Robin, we'll get caught-"
"No, we won't, they won't come in here." For a moment, the darkened room was silent and still, and then Bertrand made a tiny wanting sound.
"Oh, blood. Fine. You know I can't resist you."
"Shhhhhhh." Robin pulled him on top of himself, easing them both out of the pyjamas they'd been provided with upon arrival at the Branagh house. "Less talking, more touching."

Everything blurred, after that, into a flurry of hands and sensations and desperately stifled moans and frantic kisses and they were thrusting desperately against each other when there was a knock at the door.
"You alright in there, Robin? All that thrashing about, sounds like you're having a nightmare-"
"Don't come in!" It was practically a yelp, and he had to stop and take a deep breath before continuing. "We're fine, Mum, just trying to get comfy..." Vampire and breather lay frozen, waiting to hear if she'd believed them or not.
"Alright, then. Night, boys." She carried on along the hallway, and Bertrand rolled off of him to bury his face in the pillow.
"Oh, blood, I knew this was a bad idea. Why do I let you talk me into these things?" The mood was well and truly broken, and Robin reached over to pick up their pyjamas from the floor, helping Bertrand back into his before putting his own on.
"Just in case they decide to wake us up in the morning."

But just as Robin was closing his eyes, Bertrand leant over to murmur in his ear.
"You wait 'til I get you home, Robin Branagh." He smiled.
"Promises, promises. Night, B."
"Good night, Robin."

"You're right," Bertrand conceded as Robin's story drew to a close, "your recollection of events seems to be missing the awkward breakfast table scene where your dad wasn't having any of it and started on about how it wasn't as if the twins had never brought people back."
"That bit wasn't as funny." Robin leant in to whisper in his ear. "Remember when we did get home?"
"Mm, I remember it knocking us both out pretty well." He rocked his hips restlessly. "And I can't sleep after a story like that..."
"Well, then." Robin pulled him closer. "Better wear you out, hadn't we?"

It was the work of seconds to get them both naked, and then Robin was trailing kisses over his scarred chest again, knowing that when he felt unsettled the scars bothered him more than ever. Bertrand reached down between them to wrap his hand around them both as best he could, feeling Robin's body stir against him. Lying on their sides, looking into each other's eyes as Robin's hand shifted to join Bertrand's, they began to move, equals. Bertrand kissed Robin; Robin nibbled at his lower lip until he gasped, rolling them over... Robin froze, pulling away with a moan.
"B, I don't want to trap you-"
"It's you, I'm safe, fog, Robin." The boy treated him to a long, searching look before beginning to move again, swooping down to reclaim his vampire's lips.

Bertrand was surprised to find that he really did feel safe.

Later, they lay pressed together, Robin wrapped tight in Bertrand's arms. He could feel the way the vampire was trying to lean away from his neck.
"B, it's you. I'm safe." Bertrand made a soft 'hmm' noise and Robin could almost hear the frown.
"Bran..."
"If you bite me, it's a couple of weeks early, that's all. But you won't. I trust you." Bertrand hesitated, then shifted to rest his head against Robin's, bringing their bodies flush against one another. It was a matter of seconds before he pressed a gentle kiss to Robin's neck and closed his eyes.
"Love you," the older man mumbled, and Robin smiled sleepily.
"Love you too, idiot. Go to sleep." And then, with a contented sigh, he took his own advice.
