I would like to expand on what matt83 and bridgette started...
Early in the day tell him you have a secret plan for this evening's naughty fun. Let his imagination build during the day.
That evening, with drinks in hand but still fully clothed, straddle him on the sofa and explain the rules of the game.
"I am going to ask you some questions, and you have to answer in a very specific way. For example, If I ask you 'Do you want a hug or do you want a kiss?' you must reply either 'I want a hug' or 'I want a kiss.' do you understand?"
Once he understands the rules of the game, here are some questions to begin with...
- Do you want me to me to take my shoes off, or do you want me to take my watch off?
- Do you want me to take another drink from my glass, or do you want me to take a drink from your glass?
- Do you want me to undo one button of my shirt, or do you want me to undo one button of my pants?
- Do you want me to lick my lips, or do you want me to pinch my nipples?
Now the pattern to follow here is that every answer he gives is actually in the form of a command to you. Of course, you show a little bit of innocent surprise no matter his answer, immediately melting into sly approval of his desire, and then you directly obey his command, looking him straight in the eye, smiling, and acting without hesitation. You are actually doing three things here: 1) you providing him very specific phrases to say that he knows are safe to say because you have already spoken the words. 2) you are defining a list of naughty activities that you are willing to do on command. 3) you are having him practice talking dirty and being dominant about it. "I want you to..." And in proper Ds fashion, while he appears to be in control, it is actually you, the sub, establishing what is permitted to happen.
The questions can progress in strength...
- Do you want me to take my shirt off, or do you want me to take my pants off?
- Do you want me to lick my own nipples, or do you want do give me a hickey between my tits?
- Do you want me to slide my fingers in my wet pussy and then lick them clean, or do you want me to slide my fingers in my wet pussy and wipe the juices all over my face?
- Do you want me to wear my thong like a necklace, or do you want me to stuff my thong in my drink glass and then finish my drink?
The questions can also be about agreeing to later activities...
- Do you want me to wear no panties to work tomorrow, or do you want me to wear no bra to work tomorrow?
- Later on, do you want to fuck my dirty mouth, or do you want to fuck my tight cunt?
- Before the night is over, do you want to use one of my holes, or do you want to use two of my holes?
- When we get to the bedroom, do you want me to be your sex slave, or do you want me to be your horny slut?
- When you are ready to cum, do you want me to swallow your load like a good little girl, or do you want to shoot your load down my throat?
Hopefully these examples will be useful to you, and inspire you to make more of your own. Assuming the evening goes well and transitions into some hot fucking with dirty talk, it could be fun to sprinkle these questions into every day life. Next time you are out at a fancy dinner and have just ordered your meal, lean across the table and ask him...
- Do you want me to slip my panties off while sitting right here and put them on the table, or do you want me to unbutton my shirt and flash you both my tits?
- I'm going to the restroom, do you want me to put the buttplug from my purse into my hungry ass and wear it for the rest of the evening, or do you want me to use your cell phone and take 5 full length pictures myself in the mirror, 100% completely nude?
Hope this helps. Please share your experiences with us.
