James' body weight is heavy and warm on Regulus, grounding and glorious and pressing him into the bed. Regulus' hand is wedged between them to stroke James hard, James groaning into his hot and flushed neck. His thighs seem so thick between Regulus' legs and it drives Regulus insane, especially when seeing his bare and hard cock hanging between them. He feels heavy and hot he feels in his hands and his mouth waters, tingling and achingly empty.
"James," Regulus breathes, "I want to put my mouth on it."
"Yeah?"
Regulus nods, panting.
"How do you want me?"
That's how he finds himself between James' thighs, James seated on the bed. Regulus' attention is drawn to his thighs, sinew and muscular and firm. His hands are feeling them up and down, pressing a line of kisses there. James smiles down at him in that lopsided, tender way of his that Regulus honestly never gets tired of, his long fingers brushing through Regulus' curls, over them.
There was a time he didn't believe anyone could look at him like that, like they were so in love they didn't know what to do with themself. Sometimes he can't believe someone like James Potter is his at all.
Regulus puts his mouth to him, looking up at him from under his eyelashes. James' eyes grow wild and round with arousal as he does, sort of spasms and writhes a little into him with a groan but ultimately holds himself down firmly. Regulus likes the reaction, so he tries to take more of him.
"Careful," James murmurs, his fingers still stroking Regulus' hair. Always so careful. Regulus wonders if he wishes he had someone more experienced, because it's surely no fun not to let go a little bit, to always have to be careful. But then James is always like this, even outside of bed, and to be honest Regulus likes it.
Nobody has ever been so gentle with him. He never realised just how much he craved it until he met James and felt a hallow of hunger specifically for his every soft touch.
He sucks and licks but doesn't think he's very good at it because he's never done it before. Somehow James seems to be having a hard time staying controlled anyway, throwing his head back and breathing hard and his fingers clenching into the sheets, but still light around Regulus' hair.
Regulus pulls off him after a while and then crawls into his lap. James is still dazed and seems to take a second to process what Regulus is doing.
Regulus puts his hands to his face and kisses him, hungry and heavy and devouring, knees on either side of James as he straddles him and arches into his body.
He lines himself up and sinks down on James slowly with his hands gripping his shoulders to steady himself, panting as he watches between them where he swallows James up, could feel his largeness fill up that aching and empty place deep inside him. James' hands are on his hips, pressing encouraging kisses to his neck, his chest. He's still loose enough from last night, but James had fingered him after he'd woken, kissed his neck and made him writhe into his fingers with quiet, sleepy moans.
Regulus has learned something about how to move by now, the way James likes it. It's still clumsy at times, but he tries to pick up the pace and intensity as he rides him. James clutches at him and holds him tightly, breathless, murmurs praises into his chest.
They come together, James spilling hot inside him and Regulus all over himself before he collapses over into James' shoulder.
