Yes (CBT)

I held Tom's testicles in my hand and a wicked idea had come to me. I had wanted to spend the rest of the night submissive, but Tom's exhaustion had put me in the dominant role and now I wanted to do as I wished. "Tom, you trust me don't you?"

Tom looked back and me, "Yes I do, but I feel like this question is going to lead me somewhere unpleasant."

I smiled at him, not a kind smile, but not evil either. I licked my lips. "I had a mad idea that I want to try out and I need you to agree. Just a little BDSM, nothing too heavy. Let's say that the safe word is Orange. Will you let me play with you?"

Tom didn't look overly convinced, "I don't know if I am a fan of BDSM." Then he looked thoughtful, "But then again, yesterday Ii didn't think I was a fan of cock, but we have sucked and fucked enough to let me know that i can't call myself straight anymore...so yeah, I will trust you to show me something else I might like."

I smiled. "Good. Now turn over and let's start with something traditional. I'm gong to tie you to the bed. I want you to spread out like a star." I tied each limb to a different corner with a scarf. i didn't have the right tools to take this further. He was laid out for ease of access. I could easily fuck him like this, but I also had access to everything else. I knew that nipples could be a fun place to start for BDSM, but my goals laid elsewhere. I removed all clothing from myself, letting my skirt fall to the floor. I placed my cock on his face and snaked it down his body to his crotch. I then used my dick to hit his. He was slowly gaining some girth as the situation excited him.

I stood back and slapped his cock pretty hard with my hand. It responded with a springiness and a pleasant noise. Tom seemed to take this in his stride, which pleased me. I then aimed for his balls. I gave them a small tap. Tom groaned, but he didn't flinch. I smiled and gave my own balls a similar tap. It was not painful as such, a little pain and pleasure together. I returned to Tom and gave his balls a slap. This elicited something more primal from him, a groan of pain, but he didn't reach for the safe word. I knew I could work with this.
