Chapter 4

The need for words had gone. Hermione climbed into Snape's lap and straddled him. He stared at her in amazement but remained still. What else could he do? He was still manacled to the wall, a fact which Hermione actually found arousing. Here was someone who thrived on being in control, forced to submit to the will of a former student. Now who's enjoying the power trip? She thought.

Hermione leaned in till she was a centimeter away from Snape's face. She waited for him to make the first move. He did. He met her lips and began kissing her slowly, softly, as though afraid she might change her mind, but she deepened the kiss instead. His lips were warm, his stubble rough, and Hermione felt a strange sensation that began in her stomach and shot down to her groin. Desire. She imagined what his lips would feel like on her neck, and at the thought Snape lowered his mouth and began gently sucking the flesh just below her jaw.

"I want to touch you," Snape breathed, running his lips lightly across her jaw, wrists straining agaist their bonds.

Hermione agreed. I want him to touch me, too. I want him free, she thought. With a loud crack Snape's chains vanished and his arms fell to his sides. He looked at the backs of his hands in amazement.

"Did I do that?" Hermione asked, astonished.

"You did," he replied and pulled her close to him, this time kissing her with the ferocity of a tiger sprung free from its cage. His hands were everywhere, burning the places he touched, making Hermione melt in his powerful arms. She could feel his naked torso against her, the dusting of hairs on his chest caressing her skin, so soft, yet masculine, almost beastly. The tactile sensation was unlike anything she'd ever felt before, and she couldn't get enough of it. She tore her lips from his and took off her night dress, desperate to feel him.

"God, you're gorgeous," said Snape, taking in her naked form and running his hands over her breasts. He flicked her nipples with his thumbs, making her shudder and grow impatient. As though he could sense her need, he gently gripped her by the throat and whispered, "Do you want me to make love to you?"

She closed her eyes. "God, yes."

"Stand up," he said.

Hermione obeyed. Without the restraints, it was obvious who was in charge. Snape stood as well and pulled her to him with one arm. She unbuckled his belt slowly, eyes never leaving his, then reached a hand into his pants and closed it around him. He was thick and hard, and he moaned softly as she gripped his erection.

"Hermione," he warned. She knew this was it. If she didn't stop now, there was no turning back. She didn't stop.

Snape slid his pants down to his ankles, then kicked them off. He lifted Hermione with ease and braced himself against the wall. He slid the tip of his erection between her legs, testing to see if she was slick enough for him to enter her. Hermione moaned with frustration, obviously ready for him, and he plunged into her. She gasped, at once surprised and aroused by his swift intrusion. She moved against him, resting her forehead against his and digging her nails into his firm chest. Within a few moments, she had her first orgasm, but Snape was still hard, his lips gently drowning her moans as he kissed her.

"Fuck," breathed Hermione, exhausted, dropping her chin onto Snape's shoulder. Then she shot up. "Fuck!"

Snape reared his head a bit and looked at her. "What's wrong?"

"Nothing happened!"

"You call that nothing?"

"No, no, I mean no magic, no clarity!"

Snape frowned. "Maybe it only works if we both finish."

"Right," said Hermione, embarrassed for having ruined the moment, "sorry, I couldn't really... help it."

"Shhh," said Snape softly, "Don't apologize. I'm not exactly suffering here." He rocked his hips against her, his cock pulsing deep inside, awakening her desire once more.

"Mmm," Hermione mumbled, "I want you to fuck me hard, Snape. Fuck me really hard."

Snape raised an eyebrow, then spun her around and slammed her against the wall. The cold bricks at her back and Snape's warm body against her chest were almost enough to bring her to the edge. Her moans grew louder, more guttural, feral. Snape took Hermione's hands in his and pressed her palms against the wall above her head. He was coming, too.

Suddenly, great jets of wild blue light shot from their fingertips, causing the room to quake. Hermione and Snape rode the wave of their orgasm a few moments longer and looked around them. They were engulfed in lightening, searing and strong, the energy seemingly coming from their palms. It thundered and cracked and shot in every direction, making Hermione feel as powerful as the electricity itself.

Then her stomach gave an unpleasant lurch as she heard voices coming from the other end of the room. Death Eaters.

"What the bloody hell is going on?" She heard one of them yell.

"I think Snape's banging the mudblood! But what's that blue stuff?"

"We must have set off their security spells!" Hermione shouted over the thundering of the blue lightening.

"Do you trust me?" Snape yelled, still holding Hermione's palms to his.

"I'm sitting on your cock, Snape!"

"Right, hold on." Snape gripped her hands tighter and Hermione knew what was about to happen. They were thrown into darkness, compressing and thick. The blue light had vanished, and so had the death eathers. They were escaping.
