It's sort of a kink of mine as well, more tied into what I call "Sexual Embarrassment", not to be confused with "Sexual Humiliation"
Sexual Embarrassment in my opinion is when someone experiences a very embarrassing situation which through no fault of anyone in particular the person orgasms. (That's a horrible explanation)
EX: A guy and a girl are making out on the couch on a Sunday afternoon while her parents are at church. She decides she wants to move things up to her room and starts stripping while heading up the stairs. The guy then starts to remove his clothes while following her, but while removing his pants & underpants on the stairs, he trips on her shirt and falls down the stairs. She forgot to mention to him that her Grandmother was staying with them for a while due to her poor health, and she had just come out of the kitchen with some biscuits when he fell down the stairs. He falls into the Grandmother and gets tangled in her, while also sending her dentures flying across the room. He ends up sitting on her face with his pants & underwear still wrapped around his legs, which are now under the Grandmother. In a panic the Grandmother flails and yells wildly, directly into his butt, which adds into his pleasure, much to his chagrin. The two try to untangle, but it only causes his climax to approach quicker, finally causing him to cum at the moment the girl's parents arrive home with the church's pastor, and his cum ends up hitting the cross hanging on the wall halfway up the staircase, which the girl is now staring down in horror from.
And that's how I see Sexual Embarrassment as.
That may not make any sense to anyone, but hopefully it's at least funny to think about. (My mind is a terrifying place sometimes).
