Gabriel is faster than Raphael. That's not bragging; it's established fact. His vision is better and he's quicker to improvise his path through the underbrush. If he wanted to escape them, he could do it easily.
Why would she want to do that, though?
Gabriel slows bit by bit. He can hear Raphael behind him, whether the constant swish of their tail or the victorious hiss they let out as they get closer. This is part of the game, and Raphael knows it, too. Michael and Lucifer might wake from their long winter naps earlier, but Gabriel and Raphael always wake together, shaking off sleep and feeling heat sink into their scales as they sun. It never takes long before Gabriel will run and Raphael will give chase.
Raphael strikes fast. The moment Gabriel lets them catch up, there's no more chance of escape. They tackle Gabriel to the ground, and she laughs. She's a painting of a dozen temperatures, each slight degree of difference one that Raphael can pick out. Her skin is flushed from exertion, her scales sun-warmed, and Raphael presses their face into her neck to soak up her heat. Gabriel's fingers delicately trace the outlines of the pit organs that underline Raphael's eyes.
Their tail coils around his own quickly, preventing him from getting away, and that sparks another laugh as he tries and fails to wrestle Raphael down the same way. The tip of his tail rattles with each attempt, useless except to warn anyone approaching not to interrupt them. Raphael finds the sound of it soothing. They know its many variations, the warning call of an attack, a scared shake for help, and this, the lazy flick and buzz of when he's perfectly comfortable.
If anyone else tried to coil her so quickly, they wouldn't fare half as well. Even Lucifer might get a nip for his trouble.
"You made it too easy," Raphael says, trailing fingers down Gabriel's chest. The friction of their twined tails feels good against their hemiclitorises, and from the way Gabriel bites back a moan when they squeeze him, he's enjoying being trapped just as much.
"Me? Let you win? Never," Gabriel says. She's looking up at Raphael adoringly. They used to wrestle like this as hatchlings, though back then, there wasn't a thought to mating in their heads. They'd often get too tangled up to free themselves, and Michael would have to come along and unknot them.
Raphael winds their tail tighter around Gabriel's. They follow the flush of heat down his body. He squirms, arching his back against the forest floor, and not for the first time, Raphael wishes their tail were longer to keep his upper body tied up as easily as his lower one. They make do with pinning his wrists above his head and ordering him, "Stay."
"Happy to," Gabriel responds. The golden scales on her chest glitter when the sunlight falls on them through the treetops. Raphael's own are deep purple.
Down they go again, searching for the vent hidden in Gabriel's scales. He exhales as they brush the slit, relaxing and opening himself to them.
"Is this a medical examination or are you going to fuck me?" Gabriel asks as they circle her vent with a finger.
"Both," they answer. It never hurts to make sure. If this is the season Gabriel finally wants eggs, than Raphael wants his body ready to have them. It just so happens that process involves getting him very needy. They sink the tip of their finger into his hole, probing shallowly into his cloaca. His tail shivers.
Raphael pushes their finger in deeper. They lean down to nibble on the sensitive scales surrounding Gabriel's slit. Her hole pulses, hungry for more than one slim finger. Raphael knows how much Gabriel can stretch. They've seen her take both of Lucifer's cocks at once before. Raphael grinds their clits against Gabriel's tail. It's tempting to find a good position and sink them inside Gabriel. They won't get as deep as their brothers, but they can also fit both inside without needing to be as patient as Lucifer had. Just the memory of her vent clenching around Raphael's swollen clits makes them moan.
They push another finger inside Gabriel. They can feel him rubbing his clits against their tail, too, and they squeeze the coils wrapped around them until he gasps, his wrists nearly moving from the position they put him in. The constant pressure of their fingers doesn't make it easier on him. There's a spot just inside Gabriel, too shallow for a cock to stimulate directly but perfect for Raphael to circle with the pad of a finger.
"Oh, fuck, Raphael," she breathes out. Her tail undulates under Raphael's, held fast in their coils.
"I thought you weren't enjoying your examination." Gabriel swears at them. "Your vent is clear, and your cloaca feels very healthy."
"I hate you." Gabriel gasps as Raphael squeezes the coil wrapped around her clits again.
"I think this spot here," Raphael continues, ignoring their brother, "is the entrance to your oviducts." They thrust their fingers in against it, massaging a small circle before dragging them out and repeating the process as Gabriel writhes underneath them. "That explains why you're so sensitive. You have eggs waiting to be fertilized." Gabriel clenches around their fingers with a whine. "But not today. Today, all you'll get are my fingers and my tongue."
They bow their head to lap at Gabriel's slit. She's soaked. Her tail rolls, fucking herself onto Raphael's fingers and pushing her clits against Raphael's scales. Raphael keeps adjusting their grip on Gabriel, sliding inch by inch without giving her enough room to maneuver. They flick their forked tongue against Gabriel's entrance. It's disorientating being this close to her, Raphael's vision either filled with blinding heat or the ripple of her golden scales. Her scent floods Raphael the same way when their tongue slides back into their mouth.
Raphael sinks their tongue in alongside their fingers. It's longer than either one, pressing just an inch deeper into Gabriel and wriggling against untouched nerves. Gabriel's getting close. The constant rattle of his tail is giving it away. He can't stop shaking, too much pleasure coursing through him.
Raphael shifts one last time and moans as their clits press against Gabriel's. They reach down with their free hand between their two tails and find their own vent. It's very hard to keep track of all three things at once, especially as their own moans begin to echo Gabriel's. Their clits catch and drag against each other. Raphael is circling their hole just as Gabriel loses control, her inner walls tightening around Raphael's fingers and tongue. She finally ignores Raphael's orders to remain still and wraps her arms around her sibling, pulling Raphael closer. It only accentuates the grind of their clits, driving Gabriel higher. Raphael just barely dips their finger into their hole, testing their own comfort with penetration, and when their body responds with pleasure, they sink it in deeper, thrusting in and out as they lick up the aftermath of Gabriel's orgasm.
When they come, they squeeze his tail hard enough that it hurts a little. Then, they relax, their tail loosening, their body slumping into Gabriel's.
Raphael gets a few moments of blessed silence.
"Now I understand why Michael gets all hot and bothered when you talk clinic-y to him," Gabriel says. Raphael rolls their eyes. A few moments, at least. More than most could realistically ask of Gabriel. "Feel free to seduce me with your knowledge of my junk anytime."
Gabriel is as comfortable to lay on as a rock left in the sun all afternoon. Raphael moves her up their mental ranking of which of their siblings is the best pillow. They yawn, fangs extending as they feel their jaw give a satisfying ache, and accidentally scrape her shoulder with them. Gabriel makes a noise and leans away until they've got their mouth closed again, fangs folded up safely.
(If they'd bitten him in the middle of fucking him, he'd probably have enjoyed it. But he's not Lucifer. He prefers pain to enhance pleasure, not to experience for its own sake. Raphael doesn't mind. They'll hand it out either way.)
"I could explain to you how your cloaca is also used to dispose of the waste your digestive tract creates," they say. Gabriel makes a face.
"Maybe skip a few of the details."
Raphael huffs. Michael would find his digestive tract being described very sexually stimulating.
Thinking of Michael, they'll need to find their way back to their nests soon. He's probably worrying about their absence. If Lucifer hasn't distracted him already. Raphael just hopes the 'distraction' is a pleasant one.
Well. Gabriel and them won't need to intervene unless they smell smoke from here.
Gabriel squeezes their tail companionably, and they cuddle her.
