Summary
It’s the way James looks, the way he moves, the way he speaks—so confident. So strong. So utterly unbreakable. No one has ever looked at Regulus the way James does. Like someone who could take it. Regulus’ storms and wildfires, his crashing mood swings and his jagged cliffs. No one has ever looked at him like he’s someone capable of unraveling, and James is just there, curious to see what might spill out.
James looks like he could take anything Regulus throws at him, and so far, he has never disappointed.
| Or: Regulus is an inexperienced dominant who agrees to take James as his very experienced submissive. Again.

Why do you have this sex plant in your greenhouse? by Jos_la_nova

Summary
Regulus should have known better. He shouldn’t have given Sirius the ability to key people into the wards of Grimmauld Place. He shouldn’t have been shocked that Sirius’ stupid friend would sneak up on him, even though said stupid friend is unbelievably tall and muscular and should make a lot of sound but is surprisingly light on his feet. He shouldn’t have been in the greenhouse behind Grimmauld Place with his new potion ingredient but Sirius wasn’t even home so he should have been safe and alone.
Regulus should have known by now that nothing ever goes his way.
~Or~
James startles Regulus while he hold a very interesting plant. What could possibly go wrong?

Remus snorts softly. “Are you ready, then?”
James sticks his tongue out at him, then gestures broadly at the space between the pillows. “I’m ready. I’ve been ready for days. I was born ready.”

Or
James, Remus, and Regulus try something new.

Summary
Regulus raises a brow, fingers toying with the waistband of Barty's boxers. "I'm just enjoying the moment. You're very handsome when you're nervous."
"I'm not nervous," Barty lies, adding quickly, "Just—new. To this." His voice dips, almost shy. "You're the only person I've ever wanted this with."

Summary
Curious, Regulus lifts the knife to his lips, licking remnants of sauce off the flat of the blade. He drags the motion out, all the way to the sharp point, leaving the metallic surface with a flick of his tongue.
It’s a successful experiment. James’ chest rises with his next inhale, throat bobbing as he swallows. Regulus smiles to himself, bringing the knife back to his tongue.
The appearance of a hand on Regulus’ knee under the table, the pressure a bit too firm, distracts him. He turns to his right, where Barty has been deep in conversation with Lily for the last half hour. He’s not looking at Regulus now, but the grip of his fingers, sure to leave an imprint on Regulus’ delicate skin, makes it very clear: he has seen everything.
