"First we'll start with posture. Keep your back straight." I ran my hand up her spine making her shiver and sit straight; pushing her breasts out.
"Good girl." I praised and stepped back to admire her. I turned and selected nipple clamps and placed them on adding a light weight to tug them down.
"Get on all fours." I guided her, the nipple clamps swinging delightfully, her ass presented towards me. I ran my hand over her sweet mound feeling the slip of her arousal, and let my fingers travel to her ass hole. I began rubbing it gently and added a generous amount of lube. I slid my finger in a circle around her hole and slid the tip in gently. With my other hand I slowly rubbed her clit in circles. I could feel her relax and open, her pussy beginning to gape for me. I picked a glass butt plug from a shelf near to me, large enough to stretch her but not so large it would rip her. I slid the cool glass against her hole, pressing the tip just in and waiting, my other hand continuing to pleasure her pussy. I slid it in further, her asshole stretched to take the girth. The plug slid slowly then slipped fast catching at the flared base as her ass swallowed it. The end sat, glittering and winking at me. Her entire body appeared to be sparking with energy, she moaned softly and pushed back into my hand. I pulled my hand away and she murmured a protest. I grabbed a soft leather paddle hanging from the wall and ran it lightly over her ass. She shivered as I bought it away and thwacked it lightly on her ass, aiming at the crease where her butt met her thighs. I bought it back again and increased the intensity slightly bringing it down on her ass and judging her reaction. I gradually increased the intensity finding the edge, the point at which the pain would be too much for her. Each stroke she tensed her body and let out a low moan then relaxed and presented her rear to me again. I decided I was going to pushed her a little, and increased the intensity again, just beyond where she could manage the pain, just enough to make her feel entirely out of control. I bought the paddle down again making her whimper and her toes curl. I waited for her to manage the pain, it took a little longer this time. I bought the paddle down again at the same intensity she drew a sharp breath in and held it. I placed my hand and her chest just beneath her breast, I could feel their heat against my hand.
"Breath." I murmured and she let her breath out in a huff, taking the pain.
"Good girl." I praised, waiting a moment to let her collect herself, then bought the paddle down again at the same intensity. She tensed her muscles and I again slid my hand to her chest reminding her to breath.
"One more." I insisted bringing the paddle down again, her muscles shook with the exertion and long moan escaping from her lips. I pressed my hand onto her burning flesh. "Shhh, good girl" I praised again stroking her ass "well done."
I bought my hand to her clit again rubbing it firmly. She gave a deep guttural moan and pushed into my hand. She was so aroused it took very little to bring her orgasm crashing through her.
"There's my girl" I whispered I was proud of her, she had done well with the pain. I slid the butt plug gently out of her ass hole, the puckered skin gasping and closing, returning back to its original tight shape. I unclipped the nipple clamps, the blood rushing back into her nipples, a last shot of pain before the scene was over.
I kissed her deeply "You did so well." I murmured. She smiled at me, her muscles still trembling from the intensity. I grabbed a thick warm blanket and wrapped it around her shaking form and scooped her into my arms taking her to the cuddle sofa upstairs. I tucked her into me and stroked her hair and felt her relax, her breathing slow. We sat like that until she was ready to return to the real world. I knew we would be doing this again soon.
