The kinkiest thing i've never done that i want to do.
Hmm. Tough question, because it opens the door to other questions like "What is holding you back?" And there could be an array of answers for that, reflecting upon both what's within your control & not in your control (or not possible). And then there's "Well i "think" this would be my answer, but would i "really" want this to happen?"
Being, i guess they call it "the bull", in a cuckold scenario with an older couple, is probably at the top of my list.
I did start a fiction short story on the subject. i got as far as "Finally. I had come across an ad for an older couple looking for a 3 way where they both wanted to be a submissive to a male. I had been looking & had placed a few ads here & there for a couple, and now this couple was about to find me."
Needless to say, i've paused from continuing to work on that to tend to other unfinished stories, etc. I tend to write sexually oriented fiction short stories based on fantasies, concepts, & imagery i've jacked off to, in some cases, over many years.
One recent concept I had was a variation on "Yoko's Cut Piece" as a "performance art". So perhaps the kinkiest thing I would actually want to do might go based on the following story i wrote, that i'll copy/paste the essential except from it here. In order to understand it, here is a link to Yoko's "Cut Piece" performance art, so when i say i would do my own variation on that, you'll have a better grasp.

Now, here's an "essence excerpt" from a scenario I THINK i'd be into:
From town to town I would go. Offering a one of a kind show to mature adults. By "mature", i mean 65 & over. If folks of either gender showed up under age, like in their 50's or even some in their 40's, depending on the discretion of the folks working the door, they mostly made it in anyway. Very few got turned away..
I was influenced by Yoko's "Cut Piece". Only I didn't want anything cut off. Instead, I wanted to experience that isolation on stage, that vulnerability, to allow people to do things to me as they wished within the confines of the "art", as long as they did not intend to inflict pain or act violently.
What i would do at these shows is stand on stage, wearing nothing but a jockstrap. Seniors of both genders could, & had, taken turns approaching the stage to do as they wanted to me. They could hug me, tickle me, fondle me, grope me, kiss my pouch, snap my rear straps, & even lower my jockstrap & expose me. I wound up experiencing all of the above.
And yes, they could masturbate me.
But the masturbation had to have a limit of 25 strokes per turn. One person couldn't just come up to me, masturbate me until i came, & just like that, the show's over. No. The idea was for everyone in the room to share me, more or less in a mutual gratification way. They enjoyed doing. I enjoyed receiving. Sometimes some of the folks would put their money into a pot, take turns giving me 25 strokes, & the one who had a hold of me when i came would win the pot. Often they would give me a tip from it.
I took the liberty of judging how i saw the crowd at the start to determine whether or not i would handcuff myself or not for the performance. More often than not, i was comfortable enough with the crowd, and i wanted to give them that dynamic that THEY were in control of my body, and i was not, to add to the effect. Once in a while, i'd see one or more folks in the audience that i thought might be potentially aggressive, risky, rowdy or dangerous, and then i'd choose to keep my hands free. But i always held the key in the palm of my hand the whole time & was skilled at freeing myself.
I liked the various folks walking up to me. Especially their first time. They have that awkwardness, but it's a warm & friendly awkwardness. Sometimes i'd whisper "It's ok", especially to the ladies. I enjoyed their giggling whenever they'd squeeze me or snap my straps, or peel back the waistband & have a peek. As if they were doing something they knew was naughty but couldn't help themselves. It's a good time for them, having the chance to do something different, and unlike anywhere else
If couples showed up, most of the time they could participate in a raffle, where the winning couple could take me home that night, schedule permitting. I was always praying a nice couple would win, or where the wife would be someone i'd want to have sex with. Oddly, with more than half the winners, the guy would just want to watch while his wife would get frisky with me & either want sex or just play with me. Since i'm not really into men, that was quite fine with me.
Now, i could've answered this post, just saying "being the bull in a cuckold situation", but somehow, for a kinky experience, i don't think that could've held a candle.
