OK, I've thought about this some more. I believe I should keep things very simple to get the desired affect. First, I'd order you to remove most of your clothing. You can keep your bra and panties on for now.
While you're doing that, I'd call a few of my male friends and invite them over to witness your humiliation. I'd also call a few of your close female friends and do the same -- hopefully one or two of them are women that you work with on a daily basis. After all, you really need some other people to watch and participate to humiliate you.While we're waiting for our friends to arrive, I'd instruct you to kneel in the corner of the living room, silently facing me.
Once all of our friends arrive the real fun would begin. You would be ordered to stand up and take a position in the center of the room with your hands on top of your head and your feet spread apart. One of my male friends would remove your bra so that your breasts could be inspected. The group of friends would take turns fondling your breasts, lifting them, squeezing your nipples and making any kind of comment about them that they like. Our guests would be invited to lick and suck your nipples if that interests them.
After a few minutes of that, your panties would be removed by one of our female guests. Now completely nude, you would once again be ordered to stand before us, hands behind your and your feet spaced widely apart. We would all inspect your pussy, running our fingers through any hair that you have, spreading your lips apart and inserting a finger or two. You begin to moan in pleasure due to all of the contact.
You would then be ordered to bend over and grab your ankles, allowing the group to inspect your rectum. You said no anal, so we would simply inspect you without any penetration. While you are bent over, you would be told that it was time for your first set of spankings. The guys and perhaps one or two of the girls would take turns spanking you. Some would use their bare hands, while others would use a wooden spoon from the kitchen, or similar items.
As you once again stand before us, the group would decide how each of us wanted to further violate and embarrass you. One of the girls would kneel down in front of you and begin to eat your pussy. Another one would do the opposite, standing in front of you with her pants down and demanding that you eat her out. You obediently kneel down in front of her and begin your task while the others in the group watch. While you're on your knees, one of the guys takes a position in front of you and drops his pants -- demanding that you provide him with an expert blow job. You dutifully begin your task and take his ample cock into your already wet mouth.
I decide that it's time for another round of spankings, so I sit down on the couch and lay you across my knee. I begin to spank you with my bare hand, this time doing so much harder than before. After your spanking, I would order you to undress me, removing my shirt and pants until I was fully nude. Once I was seated again, you would be instructed to crawl between my legs and begin to suck me off while the group watched.
