When I was a kid I found quicksand fascinating. It could be a cartoon or a live action movie, it could be a male or a female or Scrooge McDuck or whatever, as a kid there was no sexual element. It was simply the idea that characters could be walking along and suddenly the ground would be liquid and slowly start to swallow them up was an amazing idea, I particularly enjoyed TV show or story where it cropped up.
When I was a teenager I saw an episode of the TV show "Monsters" where a guy took a woman home to feed her to some sort of bed monster. The way the lady in lingerie was sucked into the bed was rather quicksand-like, except also with tentacles grabbing her. (Had a look on youtube and found it here, just after 28:55
http://www.youtube.com/watch?v=LgmVJp9kx-g .) I was amazed, but found it kind of arousing. I wasn't a fan of the fact that she was terrified and whimpering and screaming, or that it was a creature that was eating here, but the fact that she sunk into the bed really did something for me. I had the strangest thought that it would have been better if there were no tentacles, and if instead of there being some kind of mouth the bed itself was semi-liquid and she was stuck and slowly sinking into it.
Many people have said that they thought they were "the only one" and that they were weird until they discovered other people with a quicksand fetish, but I immediately thought that I couldn't be the only one. The idea of a semi-naked lady stuck and sinking deeper and deeper into a thick undulating ooze seemed inherrently sexy, and while it wasn't something I was likely to broach with anyone in ordinary conversation I was sure that there must be other people that thought the same way. Later, when I first got access to the internet, I did a search for quicksand and quickly learnt that I was correct.
I'm not into bondage (I don't mind it, it just isn't anything I actively seek out), I'm not into monsters, I'm not into drowning, I'm not into any sort of peril other than quicksand. (And ordinary sexy stuff excites me fine, it's just that quicksand happens to strangely excite me as well.) I'm not into "grim" scenes - if the girl doesn't survive, that puts a complete downer on the experience for me. A girl struggling in quicksand is a turn on for me, but
death is not.
And as well as enjoying dramatic scenes, I also enjoy erotic scenes where the girl is enjoying it. I enjoy a girl having fun in the mud, as long as it is deep, it doesn't do much for me if she is just sliding around on a muddy surface, it is the sinking/stuck element that does it for me.
I think my favourite is probably where a girl is trapped and sinking, but when struggling to escape the sensations against her body are stimulating and she can't help but be turned on. I'm not into rape, but for some reason I'm excited by the idea of a girl on her own being aroused against her will simply by the environment around her. She isn't being violated by anyone, rather it is like her own body has betrayed her.
It's a completely ridiculous scenario - in real life, regardless of physical sensations I'm sure someone wouldn't be turned on if they were genuinely in trouble, unless they already had a pre-existing quicksand fetish. But it's one of the first sexual quicksand ideas I ever had - that the squelching and the suction and the pressure and the undulating movement were very sexual, not just for the observer but for whoever was in it. Back in the early days of the quicksand community there were many written stories that features trapped women being unexpectedly aroused and torn between trying to escape and enjoying the sensation. There have only been a few videos with that concept, mainly because it's an unbelievable situation.
Years back MPV did a couple of videos along those lines - in "Here doggie!" the girl falls into quicksand while searching for her dog, and ends up stuck waist deep and struggling at that depth for several minutes, rocking and sliding back and forth, until she starts saying stuff like "oh no... yes... no... yes!" The fact that she seems stuck at that depth rather than ending up deeper helps make it seem a bit more plausible, she is stuck and inconvenienced but not in danger.
There was also "Lost her grip" in which a girl with a fetish goes to a mud pit with a rope to sink and pleasure herself, but when she tries to move the few feet to grab the rope her movements in the quicksand cause her to be stimulated and orgasm again, and her motions and thrashing around cause her to sink deeper until she can no longer reach the rope, she goes under while having another orgasm. The title is pretty clever as the problem is not that she lost her grip on the rope, rather than she lost control. Despite not liking "grim" scenes, I couldn't help but enjoy that one as it her own pleasure and loss of control that causes her demise. Still, a bit of a downer ending, and I'd have loved it if she was rescued in some way.
That's something we don't see much of - rescue scenes. I'm sure there are many guys that enjoy the idea of rescuing the damsel in distress, but since most scenes done by quicksand producers feature just female models it isn't a common scenario, except if it is a girl rescuing another girl. I'd like to see more rescue scenes, I want danger and excitement and a happy ending. I was to have my cake and eat it too.
Some of you may know me from Damsels in Distress Visual Productions but for those who do not my name is Sarah Michelle and I am quicksand model in the New England area. 
. Though i have never done this since my pit is not that deep do you gals like jumping in the deepest part and sinking really deep? in my opinion those are my fav scenes other than the scenes with the peat pit which are classics love to here what you think. oh and do you like sinking at night or during the day?
I also get it from watching QS fetish videos.
