Mistress decided that I was to receive a large dose of stripes. She wanted to see how red she could make my bottom and how many marks she could leave on it to show that I am her property. She wanted the session to last as she enjoyed flexing her favourite cane and crop and she especially liked seeing me wriggle as the welts arose more and more with each fall of her hand... I was tied naked to the frame, standing up, so that Mistress could move all around me. My arms were secured to the sides and my ankles were secured likewise, my legs spread apart. As always, Mistress did not just jump straight it but proceeded to turn both of us on. She brushed her body around mine, her lips across my face and neck. She played with my cock and balls, then squeezed them until I moaned and thanked her. She licked, sucked and then bit each nipple hard. I moaned harder and thanked her once more. Mistress told me she was getting turned on and, after wiping her hand between her legs, wiped her juices across my face and under my nose. She wanted to ensure I would smell her at all times. Mistress went over to the toy table and came back with a small leather strap that she secured around my cock and balls. It was no ordinary strap and I soon found out why. She went back to the table and brought over a small black box. She explained that this was to ensure I took my punishment. She pushed a switch, pressed a button and I felt a strong tingling in my cock and balls. She pressed the next button along and the sensation was stronger. The third button she pressed was so intense I could not help wriggling. She told me there were five levels and device was used to keep small dogs under control as a training collar around their necks which happened to be just the right size to go around my cock and balls. She told me that as I was being caned and whipped, I was to thank her for each stroke, count them and ask for another. If I didn't, or I moved around too much, i would get shocked and each time it would be higher. She pressed the fourth button and the pain shot through my cock and balls, leaving me gasping for breath. She reminded me there was one setting higher... Then she went behind me and started using her hand then a paddle on my bottom. Sometimes she fiddled with my nipples or my cock or balls as she did this, making me squirm. My bottom soon felt glowing... Mistress told me she was going to begin. She told me she intended to give me 300 hundred strokes and by the end they would be hard. I was to begin counting. The first few strokes were gentle and I thanked her as ordered, counted off the number and asked for another. By the time we reached 15 it was beginning to sting. On the 19th one, I could not help wriggling, trying to get away from the pain. Mistress shocked me and I thanked her through clenched teeth and ask for more. This continued with the pain rising and, every so often, Mistress shocking me with the device to keep still. I was getting warm but knew I had to endure it for Mistress' pleasure. As she walked around me I could see her playing with herself and she wiped her fingers over my face again and told me I was doing well and pleasing her. The number of strokes soon rose and I sensed myself going into subspace. I could feel Mistress was hitting me harder, and in one sense it was painful, but in another I was finding that place brought on by the endorphin rush. I lost count occasionally and after shocking me Mistress re-took the stroke. We reached 200 and my bottom felt on fire. Mistress said she was very pleased as she ran her hand over the welts I could feel rising on my bottom and tops of my thighs where she enjoyed hitting sometimes. Mistress told me that she was taking off the strap around my cock and balls as she wanted me to concentrate on enjoying the last 100. She promised me they would each be hard. She used the crop and cane. She took each stroke carefully but rhythmically. She told me I didn't have to count any more as she would. I was hovering between the pleasure of subspace and the pain of the moment. She got to the last 10 and gave me 10 very hard final strokes. I was panting. Mistress released my arms and legs and I flopped down. She started rubbing my bottom and running her fingers over the deep welts. I could not see but the fire in my bottom told me she had left me with something to remember her for some time to come. She rubbed and ointment over the marks and we both came down together. My bottom glowed as I snuggled into Mistress lap, please I had taken my punishment for her and she seemed please too...
