Sophia seemed to be growing rather attached to me now that she had opened up and come to terms with her new sexuality. It was quite nice feeling her small, warm body snuggled up against me, so I let her stay for a while longer knowing that what I was about to do would likely push her out of her comfort zone. I wouldn't do it right away of course. Like everything, I'd ease her into it, gradually getting more intense. Would she reach her breaking point and use her safe word? Or would she continue to obey past her limits to keep me satisfied? Time would tell.
"You've been a good girl for me so far, kitten," I said soothingly, brushing my fingers through her soft hair. "But not enough to earn an easy reward yet, so I need you to continue being a good girl for me, ok?"
"Yes, Miss Rose, I can keep being a good girl," she replied softly.
"Now, remember when I tied you down for being a bad girl?" I asked.
"Mm-hmm," She hummed.
"Well I'm gonna tie you up again, not as punishment, but to introduce you properly to some bondage play, ok?" I explained calmly. "There will be some pain sometimes, but again not necessarily as punishment, but to show you that pain can be pleasurable too. Understand?"
"Yes, Miss Rose," Sophia said with a hint of nervousness in her voice.
"That said, if you're a bad girl, the bonds will get more restrictive and tighter, and the pain will get more intense," I continued. "I'm going to push you, it might get uncomfortable, and I'm not going to listen if you tell me to stop. Use the safe word if you absolutely feel like it's too much for you to handle. Ok?"
"Ok Miss Rose, I'll try," she said weakly.
"Good, now get up and get on all fours in the middle of the bed," I ordered.
Sophia obeyed and rolled away from me. As I rolled off the bed, she got up on her hands and knees just like I said. While she did that, I went over to a chest where I kept all my ropes and straps and other bondage gear. I pulled out a few short lengths of soft nylon rope and carried them back to the bed.
"Now put your face down on the mattress and stick your hands between your legs so that fine butt of yours is sticking up in the air," I commanded.
Sophia followed my instructions and went face down, ass up with her arms thrust between her legs. I took one of the ropes and tied her left wrist to her left ankle, then went around and did the same to her right wrist and ankle. It was a simple binding, not too complex, and a perfect introduction.
"Try to pull your wrists free," I said, sitting back on my heels to admire my work.
Sophia pulled on her restraints but they held tight, the ropes not even sliding up her legs.
"Are they too tight?" I asked, reaching over to rub her back between her shoulder blades to keep her calm.
"No, Miss Rose," she replied, her head turned away from me at the moment.
I slid my hand down her back to her perfectly presented ass and gave it a firm squeeze. I couldn't resist giving her a sharp spank too, the sound of my palm striking her cheek echoed in the large open room, and I was rewarded with a yelp of surprise. I raised my hand and spanked her again, and again, then rubbed the soft skin of her ass to soothe it.
"Do you like it when I spank you?" I asked mischievously.
"Yes," came Sophia's quick reply.
I spanked her again, harder this time.
"Yes?" I repeated, waiting for the full answer.
"Yes, Miss Rose!" Sophia corrected herself.
"Do you now? Then I wonder what would make a worse punishment then, spanking? Or withholding spanking?" I mused.
