A/N: Tonks' point of view.
Tonks watched Hermione hurry from the room, clutching a vial tightly in her hands. The bushy hair falling past the young girl's face did little to hide the pink blush gracing her cheeks. Tonks perched on the seat next to Severus, a smirk firmly planted on her lips.
Severus glanced up from where he was tidying up the previously used potions ingredients, "Something on your mind Nymphadora?"
Her smirk broadened and her eyes sparkled, "Based on our relationship, I knew you didn't mind age differences…but she's a bit young don't you think?"
The only indication that her remark had any effect was the momentary pause in Severus' hand as he reshelved the jar of adder skin "She was merely helping me make an antidote for the Weasley boy. And beyond the fact of her being irksome, a know-it-all, and a Gryffindor, she is a student. That is one line I never cross."
"Awww…that's a shame…" Tonks responded, her lower lip puckered in a mock pout. "I probably still have my old school uniform packed away somewhe-"
Severus reacted quickly, fisting a hand tightly in her hair and pulling her close as he towered over her sitting form, "The uniform would be pointless, my dear , since I would quickly have you wearing nothing. Much as I would like you right now."
His words were measured and deadly soft as they whispered past Tonks' ears, a shiver running up her spine at the sharp pain caused by Severus' firm grip and the firm order in his voice. Her eyes flared wide at what exactly that order had been. A warm blush crept across her cheeks as he let go of her hair, backed up, and folded his arms, content to wait and watch.
Tonks glanced nervously at the still open door she had walked through that led out to Severus' office. She knew only those Severus invited could enter his private chambers, but she wasn't sure about his office. Either way she felt decidedly more exposed as she glanced back at Severus, a pleading look written on her face.
Tonks huffed out a sigh when Severus merely raised an eyebrow urging her to continue. Her hands moved down to quickly take off her pink and black striped shirt. She had been naked with him multiple times, but standing here, stripping as he watched and knowing his eyes wouldn't miss a detail? Bloody git. I was just joking! Tonks thought angrily. But you enjoy it. Her mind argued back. Shush! …Might as well get this over with.
"Slower." Severus intoned as Tonks went to pull the top up and over her head. Both her thoughts and her hands froze momentarily at the sound of his voice. As her hands took on a slower pace, her mind picked up its momentum of cursing the man standing in front of her along with its adamant denial of the her ever increasing excitement. Tonks looked down after taking off her shirt. She had forgotten that she had chosen a matching pink and black striped bra and then groaned inwardly as she remembered the booty shorts and knee highs that were also part of the set, all of which would be revealed as she continued to strip. Earlier that morning it had seemed fun and playful, now it looked planned. Could be worse…you could be wearing white cotton and work socks. Her mind chimed in helpfully.
Tonks hid the ever growing blush on her cheeks and the roll of her eyes as she bent over at the hips to untie her boots. As she slipped off her boots and slid her pants down over her hips she couldn't help but notice the slight upturn at the corner of Severus' lips. I must look ridiculous! Tonks thought and moved quickly to take off the rest of her outfit.
"Stop." Severus' voice had Tonks glancing up nervously. "Turn around slowly." Severus added with a motion of his fingers. Tonks obeyed, feeling sure the motion was only for her increased sense of embarrassment. "Pity that such an outfit will get in the way of what I have planned," he said almost to himself, his eyes roaming over her body before returning to meet hers, "Continue."
Tonks felt a thrill of joy as she realized he liked the outfit and that she wouldn't have to keep it on. The cool air in the room caressed her body as she removed the last article of clothing.
"Kneel," Severus ordered as he took a collar out from behind his back. Tonks obeyed, realizing he must have wordlessly summoned it while she was stripping. Severus knelt in front of her, collar in hand. He went to move her hair to the side and then paused, "Shorter hair would be best for today." Tonks concentrated and formed her pink hair into a short bob. "Good girl." Severus encouraged as he latched the collar behind her neck. "For this scene you will not speak unless asked to do so or unless your safeword is required, nor will you come until given permission. Understood?"
"Yes Sir," Tonks responded breathlessly, anticipation rising within her.
"Now close your eyes and hold still." Severus ordered before standing and moving away from her.
Tonks did as ordered, the anticipation reaching almost unbearable proportions as she felt him get up and move away. She tried to focus, tried to listen to find out where he was, what he was doing. She clamped her eyes shut to fight the urge to peak, just so she would know. A thunderous crack went off next to her head causing her whole body to jerk in surprise. A scream caught in her throat, partially due to her surpise but also due to the fact that the sound sounded like it should have hurt, it was too loud, too close. It took Tonks a minute to realize it hadn't touched her at all. The brief relief was short lived as she realized exactly what the sound was. A WHIP!Her mind screamed. As if in confirmation of her guess the same loud crack sounded on the other side of her head. Her mind filled with images of the one and only time she had seen a whip used, by Severus no less, when he had been in her mind. With each snap of the whip, the girl's cries of pain transformed into ecstasy as the skin turned deep red.-lash after lash landed, cutting her skin and seeing red seep up from the wounds.-Bellatrix easing herself forward, eager to touch and play with the blood beginning to trail down her back. Severus sending a warning crack towards her to stave her off—Tonks almost screamed her safeword right then and there. But Severus' description of the scene with Narcissa, it wasn't at all like that…and I said I wanted to try…he hasn't even touched me with it yet. Tonks tried to comfort herself, to force down the thoughts that had just moments before threatened to drown her. She braced herself for the first hit of the whip, which she was certain, would come sooner rather than later.
Come it did, but not in the blinding pain Tonks had prepared herself for, but in almost soft kisses, the tip hitting one cheek before hitting the other before returning. She knew it could do worse-A lot worse! her mind shouted, but she now knew it didn't always have to. It was thrilling, to have something so dangerous be so soft, so controlled. Each kiss was like a threat disguised as a caress.
"Nymphadora, open your eyes, stand and move to the center of the room." Severus voice rang out. He met her at her destination, cuffs in hand. He attached one to each wrist, raising them above her head to attach to chains now dangling from the ceiling. The length of his body was pressed along her back as he whispered in her ears, "Spread your legs…good girl."
Tonks almost whimpered when the warmth of his body pulled away from her, replaced by the cool air of the room. Having her eyes open no longer mattered. He was behind her and no matter how hard she tried she couldn't see him.
"Hold still" His voice called out and she froze. The action was rewarded with the first strikes of the whip. They stung more than the light flicks on her cheeks, but they didn't last like the sting from a paddle or flogger. They were bright flashes of pain wherever they landed, that seemed to fade the moment they became too painful. The patter of strikes, of pain fading and building was almost hypnotic in nature. With her body frozen, it seemed to be her spirit her very nature that swayed and moaned with every impact, that wanted to cry out for "no more" the instant the whip hit only to moan "please don't stop" the second after.
Tonks was in a sea, riding wave after wave, and only dimly aware that Severus had moved around to her front. Her awareness came back in a rush as the whip struck each of her nipples in turn, her eyes going wide and a yelp escaping her lips. The bright pain rode a circuit, along her nerves, down her torso and to her clit causing her to moan and move her hips forward slightly. Severus' soft chuckle seemed miles away as she was once again pulled under by the steady rhythm of the whip, down her torso, down her thighs, around to her back before returning again.
Her whole body protested when she reminded herself through the haze that she wasn't allowed to come without permission. Every time she would almost get to a point of no return, the whip would snake away to less provocative areas. The third trip around her body, now covered with a pattern of pink stripes, the hits began to land solely on her nipples and the insides of her thighs, making her hiss and moan, making her want to beg.
"Nymphadora. Come. Now." Severus' dark voice was like water to a man dying of thirst. It was her savior and all she cared about at that moment. To drive his point home, Severus flicked the whip up to land directly on her clit.
Tonks' whole world shattered as she came hard, her body feeling like it was shaking apart, her legs refusing to hold her any longer. The waves she had felt like she had been riding the whole time were crashing over her, drowning out the sounds of her own cries of ecstasy.
As the waves of orgasm subsided, Tonks became dimly aware that she was no longer standing and had been lowered to the ground. The cool stone felt good on her body that all of a sudden felt too hot, too sensitive. She glanced around quickly.
"I am right here," Severus said reassuringly as he strode over, a glass of water in his hand, "and you did very, very well. I am very proud of you." He helped her sit up slightly and held the water for her to drink. Seeing something in her eyes he cupped her chin, "you may speak now."
"Thank you, Sir…" For the water, for being here, for being you, for the whip, for letting me come, for… "just…thank you" Tonks repeated as she snuggled closer.
