Get onto Fetlife or a similar site and look for a married couple, discuss your predicament with them. Leave him tied up outside room or in the bathroom.
Double date and he can be the only one caged up. Leave him tied up outside room or in the bathroom after dinner, with a eyemask. U dont have to play if you dont want.... U just have to watch or be present use a dildo while u watch them. When the guy comes or the girl squirts or both. Smear some on him let him know ure done for the evening.
Let him clean up the cock or a pussy. Then remove the mask upon leaving.
If you are reading this, Snowy31, my wife and I could be down in Birmingham on the night of Friday 18th and do this past midnight to see in his birthday.
Have a meal together. Lots of flirting. Loads of compliments for you.
Then, at the end of the meal, we will all join together and strip him, then sit him back down on a chair and tie him to it.
Then you fetch the cage. Don't mention it to him between now and then. He might think you have forgotten that you have it.
Up to you what happens next...
Do you want to put it on him, and tell him that he asked you to do this, so you thought you would go all in?
Or have my wife put it on him, while she tells him he is getting nothing tonight?
Or have me look him in the eye and tell him that I am really going to enjoy tonight as I snap it shut around him?
Which would turn you on the most? Which would he find most humiliating?
Then we put on some music and tell him that you have gone to a lot of trouble and arranged a birthday disco for him, so he had better enjoy it!
We all dance together. Maybe a bit flirty, a bit touchy feely. Each of us sticking our bum out for a bit of a spank, or feel.
My wife could go over to him and stick one of those party blower things that unroll and make a noise in his mouth. Tell him that seeing as he can't show his appreciation with his cock, he had better show us how aroused he is by blowing that.
Then the music gets slower. We entwine a bit. Hands everywhere. (Optional for you to join is as much or little as you want at this point with snogging and groping of either or both of us)
Then one of us asks you to lift your dress.
We slowly pull down your knickers, right in front of him. You go and pull them over his head and eyes. Then my wife's knickers. Then, finally, my boxers.
He can't see, and can smell how excited we all were.
Then you go over to him and whisper in his ear:
"We're off to the bedroom now. You'll be OK here, won't you?"
Then we go through, and you are in charge. If you want to play with either or both of us- that's great. If you want us to fuck while you use a vibrator on yourself, until we all cum noisily, that's fine, too.
You say what happens to my cum. If you want it on your body or clothes so that you can make him lick it then that's what will happen.
What next?
We could leave, or we could ...... with you in your bed while he sleeps, still caged, on the couch. And he could make us all breakfast, as our Naked Chef, on his birthday.
Message us if you want this to happen, or to discuss alternative scenarios. I have a great imagination!
