Today has been very busy. My key holder's friend is quite dominant, as well as being VERY needy sexually. I was bound to the bed, and she my chastity removed. She knelt over my face, and bent over so she could play with my penis and the dildo that is locked into me. She warned me that if I started to become erect, she would make it go away. I was told to lick her, and to continue licking as long as I could. I started to get erect, and she hit my balls with a ping pong paddle. When I stopped licking briefly due to the pain, she commanded me to continue licking, and then told me she liked riding my tongue so much that she would give me a treat. I had no idea what she meant, but she took my penis into her mouth, and started hitting my balls every time I started to respond to the stimulation. This went on for a long time, and then she got up and asked where I kept my toys. She discovered my KTB, which is about 2.5 inches long with many sharp spikes inside. Once it is installed, there is no way to remove it, and any erection is a real problem because I respond to some pain, and the more erect I become, the worse it hurts. I toyed with it for a few days, but it was too intense for me to wear over time, and I should have thrown it away. She thought it was a lovely toy, and after she locked it on me, she gave me a blow job until my begging her to stop finally sank in. She then dressed me commando, shirt and trousers, shoes & socks. unlocked my wrists, and we went out shopping. She bought me a garter belt, open crotch panties, stockings, and a bra. She teased me constantly, gently rubbing her breasts against my chest, even handling my package in public, which kept me trying to erect, which caused me pain, and every time she knew I was hurting, she told me not get erect. When we got home, she undressed me, and locked my wrists and ankles to the 4 corners of the bed, and once again 69'ed me. when she saw me start to get erect, she would orgasm. Eventually, she removed the KTB, re-installed my old chastity, and then nursed me. She has told me that she will 69 me every morning and every evening while she stays, and I suspect I will be in the KTB. I am very sore, and have not had an orgasm.
