"Did you mean it?" he asked quietly, unsure where the gumption to speak up in that most private of moments had come from.
"Merlin, yes, I- I- what the-"
The Slytherin girl had frozen mid-word and mid-stroke, then her head spun almost supernaturally quickly to meet his eyes. She screamed, but stifled it almost immediately.
For a moment, all he could see in her dark eyes was terror.
It horrified him to see, after the beautiful, mesmerizing sights and sounds he'd just been treated to.
"If you meant it, I'll... I'll do it," Harry said quietly.
She swallowed. He watched her thin throat move.
But aside from panting, she made no sound, or move to cover herself.
"No one has to know," he assured her, hoping beyond hope that Lilith was not lying about her potency, about her abilities, or about the girl in front of him. "Just you and me." And Lilith. She's staring...
"No one...? Not- not Weasley, or Granger? Not- Dumbledore?"
Her voice was hoarse from panting and her sudden scream. Harry nodded, "No one. Just you and me," he repeated, feeling lame for saying it again.
"Then yes," she moaned, "Yes. Merlin, for so long I've... No. No more talking!" After a moment, the girl had stood up, pulled the bra straps from her shoulders so that they hung loose, then pulled it down around her torso even as she stood, then turned to face him in all her glory.
Yep, he idly thought with some part of his brain that was still partially functional, she's a natural blonde.
The sparse hair between her legs appeared to have been trimmed regularly into a thin patch, not that he had much to compare it to, and her breasts, free at last, hung just slightly on her chest, the small areolae, light pink, almost invisible against her pale skin in the moonlight, a bit to the outside, with small, but protuberant nipples.
"The table," Lilith whispered from behind him, "tell her to get on the table. It'll be more comfortable than the chair."
Harry nodded, then glanced around. The girl's own study table was still filled with books and what looked like a History assignment- no wonder she'd fallen asleep.
But the table next to it... He pointed, "Get on the table."
"R- Right," the girl whispered, then scrambled to obey.
Without taking his eyes off his soon-to-be conquest, Harry followed, hands twitching to grab at the shapely rear. When he reached her, though, the Slytherin girl was already sitting on the edge of the table, legs spread, waiting. Her eyes tracked his movements, and Harry stopped just a step away.
"I've... I've never..."
"Me neither," she murmured, and suddenly she erupted in a light blush that covered the whole upper half of her torso. "But I'm glad it's going to be you. Come on... I'm so horny!"
The tender tone of the first two sentences was ruined by the last, as her voice took on a desperate, even demanding tone.
"Okay, Master," Lilith whispered again, "you can take her whenever you want. You probably don't even need to be gentle... I gave her quite a dose. Just take some care for her needs, won't you?"
"Er... I'm not sure where to start," he admitted, not sure if he was talking to the Slytherin or the succubus.
"Use your tongue and hands on her breasts, first," Lilith suggested quietly, "males seem to like that... I do, too. It feels good for females, too. Then maybe your hands on her cunt, like she was. When you can't hold out any more, put it in. She'll be fine."
Harry tried to oblige, stepping forward once more so that his engorged penis brushed against the girl's soft thatch of pubic hair, and started to lean forward with one hand outstretched.
He did end up getting his right hand around the girl's left breast, holding the whole of it rather neatly, he thought, before her own left hand jumped down between them, grabbed a hold of his penis, aimed, and then, using her legs wrapped around his waist, pulled him in with a mighty heave.
"Uungh," she grunted, eyes grimacing shut momentarily.
Harry noticed none of that, though.
Instead, almost like when Lilith had taken him in her mouth, he saw only white.
The moment passed quickly, though, because that vague sense of unsatisfaction, that empty hunger, came roaring back with a vengeance.
When Harry's eyes opened from the shock of being forced by the girl he was currently inside into just that place, they were hard.
Desperate.
Needy.
Strong.
"You don't get control," he heard himself say, "I'm the Master, here."
Then his hands fell on her wrists, pulling both up over her head and then locking them in place with his left hand, leaning forward, while his right was freed up to resume his groping of the girl's chest.
"H- Harry... I don't care," she gasped, "Just- just move! Please!"
With a grunt, Harry complied, forcing his hips to move out of where they most wanted to be.
The pleasure was exquisite, all wet silk and heat.
Going back in doubly so.
One controlled motion was all Harry could manage before he lost all semblance of restraint.
The second thrust was wild, hammering into the girl so hard her breasts bounced.
The third and more were harder still, faster and faster, until the once-straight hair was tousled and sweat-drenched, just like her slick, pale skin.
The only time the breasts did not bounce with the pounding he was giving the girl was when they were in his hand or hands, for he released her own arms about ten seconds in.
But she did not fight him off. Instead, the girl wrapped one arm around his neck to steady herself, while the other alternated between the breast he was not currently mauling and her mouth, occasionally sticking one or two fingers in, sucking on them, then moving the hand back to her chest. All the while, she could only desperately inhale air as he withdrew, only to have it all driven out when he pounded back in.
