Cake sitting is a growing sub-fetish of the WAM genre, and combines elements of WAM with the crush fetish. Cake sitting may be enjoyed as both the sitter and the watcher. For both, in order to ensure a truly exciting sit, here are some guidelines. (1.) Cake position--the cake should be on something such as a chair, stool, or plinth, so that it is easy for the sitter to straddle the cake and rest on it in a comfortable seated position. If the cake is on the floor, it is more difficult to sit down in an upright position, which risks obstructing viewing and the cake not squishing out so much. Additionally it's important to position your cake so that it will not slide; many a good sit has been ruined by the cake sliding out from under the ass, resulting in a disappointing half crush (see Cake condition below).
(2.) Cake type--The cake should have soft moist sponge and lots of frosting, preferably decorated with more piped frosting. It should be as soft and gooey as possible. It should also be wide, and deep--the best cakes should be of similar diameter to your ass. Costco cakes are ideal for this, or some
chocolate mousse-cakes/ gateaux/tortes. Nobody wants to sit on a dried out cake with hard
icing, and it doesn't look any good either. (3.) Cake condition--part of the thrill of cake sitting is the destruction of something pristine. It's completely taboo--someone spent time decorating this thing, so it should remain perfect until the moment of the crush. Don't add extra cream or frosting (it should be there already), and don't half crush it first. The cake is intricate and took work to create, and crushing it is naughty and against the rules. This is why we don't use pies for sitting (it's ok to sit in a pie, but less visually appealing and doesn't slowly squish all over your ass in the same way, so I might suggest smashing the pie in your face while you sit on the cake).
(4.) Be naked! Another part of the enjoyment of cake sitting is the feeling of frosting squelching all over your ass, up between your cheeks, around your erogenous zones and maybe even penetrating you. Don't ruin the fun by wearing clothes of any kind--be naked (at least from the waist down). Also consider spreading your ass cheeks as you are ready to sit so the squishy mess is sure to cover your asshole during the process. Also try to keep your legs open to show off your pussy or cock as well to your viewer.
(5.) Sit speed--don't rush it, but enjoy the feeling of lowering your butt slowly into the cake. As the cake crushes, the sponge will bend and then break, smearing the frosting all over your butt. The watcher will see the cake bend, then bulge, and then burst, expanding outwards and oozing apart. Savour the moment, however never go backwards as this ruins the visual spectacle of the cake oozing out from under your ass for the watcher. If you need to come up again, wait until after the cake is fully crushed, so we can see your frosting-covered ass. Don't twerk, just crush. Splat that cake in one smooth slow sit. Just touch it with your butt and then slowly let your bodyweight do the rest.
(6.) Grind it--once your down in the cake and finished sinking (once the sponge has slowed down and your butt is no longer in the gooey caress of the cake), smear the cake with your ass to get every tickle and slip from the cake. If bits fall on the floor don't worry, it's all part of the spectacle of seeing this beautiful thing get destroyed; all the hard work splatted on the floor. Take bits of cake and rub them into your pussy or cock. Masturbation is part of cake sitting--it should be an intensely sexual experience. Also be sure to show off your messy pussy, cock and asshole to your partner so they can enjoy the messy view even better!
(7.) More than one--most cake sitters will probably exhaust the splat potential from a cake before they reach orgasm, so therefore it is usually necessary to have several standing by. Keep them easy to reach so you can place them on your chair or plinth without too much effort. Repeat the above steps until there's so much icing in your holes and so much splattered cake that you just can't keep orgasm inside any longer.
(8.) How to take it to the next level--consider stacking cakes to make one very large cake, sitting on lines of cakes on a bench, or crushing cakes between you and a partner, perhaps while having sex. Find inventive ways to destroy cakes with your naked body.
To sum up, proper cake sitting is about using your ass, asshole and sex area to flatten a cake. If you have the right kind of cake, not only will it make a lovely squish and feel very naughty, but it will initially "kiss" your nether regions as you make contact, followed by a licking/massaging feeling as you sink through the layers, pushing them aside. With a little grinding and rubbing, it can prove to be extremely stimulating, sensual and sexy.
