Severus turned capturing Darco's lips in a soft kiss releasing him only to give a small smile.

Hermione watched the play between the men, the gentle kiss warmed her, they cared for each other deeply, more than a small part of her hoped that when this was done she would also share with them beyond the bond, a caring relationship based on trust and time.

"Now Draco what would you like?"

The blonde shuddered as the Potions Master spoke to him, Hermione smiled she knew exactly how he felt.

"Both of you together." Draco's voice was sure

"And have you done this before?"

A flick of warm tongue traced the lobe of his ear eliciting a small moan.

"Never at the same time."

"Perchance you should ask Hermione her views on this hmmm" another lick, stygian eyes found whiskey brown

"Hermione?"

Malfoys' didn't beg but she didn't need to look to know Draco's eyes would show near palpable desire, she wouldn't deny him this.

"Yes."

He breathed a huff of air out, he'd been holding his breath waiting for her answer; she gave him a small smile finally looking at his relieved face and started to worry that she would be good enough for him.

"Kindly don't start thinking too much."

"I can't help but wonder.."

"Don't"

Severus started the delicate manoeuvring to the bed; Hermione's and Draco's first threesome.

If Hermione was truthful she had expected Draco's bond to come much like hers had been, fire hot singeing everything but it hadn't. Draco was inside of her, Severus him. They were doing this all together too slow movement which tantalized, she moaned, Draco eyes closed, ecstasy written across his face, every thrust pulling a near mewl from his throat as Severus stroked, hand fisted in pale blonde hair and whispered in his ear much as he had done to Hermione.

Draco's bond gave goose pimples all over Hermione's body as if she's stepped into the Scottish winter naked, her heat rose to meet it, she flushed, shivered, sweat began to dot her body.

He gave a small movement of his hips and grazed her gspot again, her orgasm began that slow build, a knot of pressure in her lower back, she closed her eyes unable to handle any more stimulation between sex and the bond; she refused to look at them, looking at them would be her undoing.

She heard the words.

"Hiscine vinculo isto? Vis autem iudicium gratiam?"

Draco's hitched reply

"Imo"

She wished she had kept her eyes open to see his startled surprise, but she heard his gasp.

He repeated it again, "Imo."

That released the spiral of pleasure knotted in her spine, it raced up, summer intensified sang in her blood. Draco followed, his cold swallowing her heat unleashing what felt like a pelting of graupel pellets on their skin. Now she knew they had felt her fire exactly as she had, she felt his cold. Eyes squeezed tight, hands clinging to the top of her head as if that could stop the feeling of her head exploding from absolute euphoria. Hermione was lost until the very last moment the bond finding its nexum fullfilled allowed Severus's power to flood them.

Severus's power devoured, heat, cold, it cared not. It consumed. It moved through the bond with a feral speed, Hermione felt her eyes rip open only to see Draco breathe out tiny crystals of ice that were engulfed by an entirely too powerful blue bell flame that escaped on her gasp of amazement, she could do that? Behind Draco Severus, whom to all appearances was in a continuous exhalation, inky power streaming from his nose and mouth filling the quickly darkening room as it filled them. At its precipice it ate the light swallowing them, it brought the very wards of Prince Hall down and replaced them, it filled them to engorgement.

The red moon was high in the sky when they finally awoke on the shattered frame of the bed, when did that happen? When had the power splintered the aged mahogany like badly cured cheap pine, beyond the ability of repair spell or charm? When had they acquired branded runes across the right wrist? Alcohol forgone, they ignored the now released doors, and drank tea coupled with a rich chocolate cake, watching the red moon in a slow march across the sky as Hermione and Draco fought to control their new powers.

Hermione taught Draco to bled his power into the wards as Whimble had taught her at Hogwarts when they both became overwhelmed with the sheer amount of power that strummed through them
He continued helping her with her occlumency, even as his failed battering her brain into mush.

In the corner Severus sat still, composed, eyes closed. At best bet he was mediating but they could sense his worry beyond that excitement, his energy pulsed with it. He opened his eyes, flicked his hand banishing the remnants of the bed and gave a satisfied grin, he had found the core of his power.

This was how their first week passed learning how to control their new powers, they duelled in the back gardens, blew up enough cauldrons to make Neville look like a potions master, split several pieces of furniture into matchsticks with simple charms and in the process learnt control.

Hermione found it disturbing that it came hardest to her, one word about Harry and she would lose control her bluebell flame bursting forth.
Yet even when Severus taunted Draco he was too weak to save his mother Draco managed to not allow his power to cascade out, he pulled into himself, frost running up his wand the first few times as he duelled against Severus. Hermione gained a new level of respect for Draco.
Oh and they shagged.
Draco was a sybarite, or maybe being raised Malfoy meant he was raised to be a sensualist, not be ashamed of his love of luxury or wanting and enjoying sex. He made sure they slept on the finest sheets, the elves created meals more suited to Roman lords than the British palate at his urging; although as long as there was meat Severus never complained even if it near bled on the table, "well done is an insult to the meat!" Ha!

He awoke them with kisses and caresses, he said exactly what he wanted and what he wanted to see, he taught Hermione la pipe, laughing as she blushed red when he called it noshing and redder at blow job.
They knelt as Severus's feet as he guided her by example while whispering to her "It is more personal isn't it? This is about his pleasure, a gift to him, you can't shut off and think of Merlin or the muggle Queen."

At the end of the fourth day Hermione had begged off because she was sore, she had pointed her wand at Severus and told him in no uncertain terms that the randy dandy was his responsibility, and if Draco came anywhere near her she was going to hex his bits off. He smirked as he summoned the pink potion he'd given her the first time pressing it into her hand, as he walked away sotto voiced carrying along the hallway

"There were no complaints last night witch."
