Frightened onlooker

I am a man of few words, but after a brief initial contact some time ago, and having tried to get together several times, we had agreed to meet up. I was nervous because she enjoys spanking, and I wasn't sure if she would hurt me or make me enjoy it.

As we had agreed, I went up the stairs, and before reaching the door, on the previous landing, she made me undress completely, which was extremely humiliating. She took off my clothes and shoes and made me crawl up the stairs on all fours.

When I entered the apartment like a dog, she took me to the sofa, where she made me give her a good blowjob to get her in the mood. By the way, she has a delicious and beautiful cock. Once there, she made me lie down on the living room table, a low table with a suitable mattress, where I lay down on my stomach, and she started to tie me up and handcuff my hands to the table legs. As the seconds passed, I realized I was in a situation where I couldn't back down, but had to endure and let her take control. Then, she covered my head with a hood so I couldn't see anything, and indeed, I was at her disposal. She started giving me slaps on the buttocks, gradually increasing the intensity, until she was giving me heavy slaps and my buttocks were getting warm.

After that, she greased up my buttocks and started working on me with her fingers until she inserted an entire dildo. To prevent it from coming out, she covered it with packing tape. Then, she made me get on all fours and led me through the hallway to another room with a bed. I jumped onto the bed on my back, and she started tying me up, still with the dildo inside me. This made me feel like I belonged to her, and I couldn't complain. She tied my hands to each side of the bed and my feet to each side, and now I was truly at her mercy. She covered my eyes again, and the seconds seemed like hours as I listened to her moving around. I was nervous, with my heart in my mouth, when she put clips on my testicles in a semicircle. After a while, I started feeling an extreme heat in my testicles, and every time she touched me, I thought it could be electricity or maybe wax, but I didn't dare speak. Then, she applied it to my cock, and it was a mix of pleasure and intense heat. Time passed, and she didn't want to continue, so I relaxed a bit.
