One of my favorites has to be complete sensory deprivation. IE can't see, can't hear, and can't move. It's good fun. What I want to do is get a pair of sound canceling headphones that allow for sound to be transmitted via a microphone so that all the person can hear is my voice. Of course at the beginning he wouldn't know this. I'd tell him that we were going to play a fun game tonight, explain the situation, that he wouldn't be able to see or hear and would be bound upright by a chain to the ceiling and have his legs spread apart by a spreader bar. He would be my toy, completely powerless to even know what was going on. Whether he protested or not, it wouldn't matter, I'd be set on it and "convince" him if he wasn't sure...
I'd string him up to the ceiling without much conversation, attaching a spreader bar so that his feet are a little more than shoulder's width apart. This way I can enjoy all of my toy. I'd blind fold him, and reassure him that everything was going to be just fine, that I love him, and to trust me and be brave for me. Then I'd place the headphones over his ears gently, running my fingers through his hair and massaging the muscles of his neck before stepping away. I'd be so proud of him for trusting me and doing this for me. I'd be so hot already, just knowing that he'd be completely at my mercy...
I'd leave him there for a bit letting him wonder what I was up to. He'd be very conscious of every wisp of air, and any small tinge of feeling on his skin. I'd walk around him, then, when standing behind him, trail my fingers lightly over his back. Nothing more. And step away. I'd watch him excitedly, unsure how long I could stand there and not play with my toy. But as he starts to squirm a bit I would take a riding crop in hand and swat him once on his ass lightly, letting him know I still expected him to be brave for me.
I'd swat him a few more times before putting down the crop and backing up again. Watching him carefully and listening to his soft whimpers. After a few minutes pass I would speak into the microphone startling him, "You're doing very well sweetie, I'm very proud of you." He'd look from side to side trying to understand where the voice was coming from when he could hear nothing else. Moving back to him and slowly massaging his shoulders and back, moving one hand to his penis now and then to tease him a bit, I would explain the microphone. I'd ask him if he understood and smile at his nod. Then I would continue my fun.
I'd use hot wax first. Loving his squirms as it flowed down his back to his gorgeous round ass. Loving the look of the few marks I'd left with my riding crop besides. I'd ask him with a laugh through the microphone, "Where else should I drip this hmm?" Stroking his cock as a suggestion. He'd squirm more at that idea in a vain attempt to escape, begging me not to pour any on his sensitive genitals. I'd love the sound of his begging, relish it but feel a bit sad for scaring him. He should know me better than that, I'd think to myself and decide to continue, Enjoying touching his body. "What about these?" I'd ask again, feeling both nipples, rubbing and tugging on one with the fingers of my left hand and the other with my mouth while I still held the candle. He's rock hard despite his fear and I wonder if he really knows I probably won't do it. He begs again anyway, knowing I love it and I smile against his chest, his nipple still in my mouth and bite it quickly and lightly, watching him jump.
"You beg so well, I don't think I will sweetie. Though I do so love to watch you squirm, there are other ways to make you hmm?" He'd smile a knowing smile and nod. "Good boy." I'd move back to the bed and sit down watching him. Every nerve in my body would be tingling; I'd need release so badly. "Mmm, you know what this does to me baby." I'd tell him melodically. "I do believe I could use some relief. But seeing as how you're all tied up right now..." I'd laugh at his attempts to convince me to let him down to help me. Seeing him there would turn me on so much I wouldn't want to. I'd tell him how I was getting out a vibrator, my favorite, and moan into the microphone as I send myself over in little time at all. He'd be disappointed, but close himself, hearing my moans.
I'd rest for a moment, telling him how wet he'd made me, how I was seeping, how hot he looks strung up there like that. Then I'd take a piece of ice and hold it in my mouth for a second, letting it chill my tongue before licking his back and shoulders where I'd dripped the wax. I'd then take that same ice cube and run it over those spots instead. His exclamation of "Damn that's cold" or something similar would just make me laugh again and I'd continue running it along his back and neck, following every movement of the ice cube with my tongue.
I'd blow on my hands lightly, warming them, before I embraced him from behind, rubbing his nipples and then his cock, trailing my fingers from it's base to it's head, watching him squirm.
