Tonks blinked, her eyes trying to adjust to the glowing candle light in the room. Every nerve in her body felt on edge.
"I am not undone yet, Nymphadora. On your knees as I have described before."
"Yes, Sir." She purred in response, as she slowly folded to her knees. She had never felt as graceful as when she knelt at his feet, spreading her thighs, keeping her back straight, her head slightly lowered. She moved to put her arms as he had taught her, but was quickly reminded of the cuffs on her wrists that were attached together. That small amount of confinement sent a thrill of excitement through her, forcing her to bite her lower lip to keep her from arching forward.
"Good girl." Severus intoned as his hand reached down, petting her hair gently, approvingly.
As the back of his hand trailed down her hair, she moved her face to the side, slightly kissing his fingers and teasing them with the tip of her tongue. She looked up through her eyelashes watching for his reaction. His eyes had closed and a moan escaped his lips. His hand pulled back and she caught the tip of a finger between her lips, sucking gently. A tight hiss escaped his lips. His hand moved and fisted in her hair, forcing her to look at him.
"Witch, you're testing me and as soft as those teasing lips are, I think they need to be put to better use." He growled out, the sparkle in his eyes showing her he was more amused than frustrated. Although, she also knew she would be pressing her luck if she continued in such a way.
Her tongue darted out wetting her lips as she leaned forward and took his cock in her mouth, swirling her tongue around the tip. As she took him deeper she could feel every moan he made as it rumbled through his body. The rich scent of leather mixed with his musky scent and filled her nose, causing a pleasurable cloud to form in her mind. She could feel herself getting wetter with the knowledge that she was bringing him pleasure. She moaned against his cock, her lips vibrating around his shaft.
Leaning in, she took him deeper, opening her throat. She held herself close to him until her body demanded air, forcing herself to pull back. Her chest rose and fell with each breath she pulled in from her nose, slightly light headed from the oxygen deprivation. Her head continued traveling up and down his cock, moving out to circle the tip with her tongue before taking him deep again. She felt his body jerk before feeling his hands twist in her hair pulling her close. She pulled against her restraints wanting so much to hold him close just as he held her close. His hips thrust in her mouth and she took him greedily, loving his smell, his taste.
Tonks pulled back, gently sucking his cock as he finished. Another moan vibrated from her lips down his cock as she noticed that he was becoming anything but soft.
