I'm not very kinky when I write, but I have read most of the kinks out there (for research purposes of course

) so if you want ideas:
bondage
spanking
playing with foods (chocolate, cream, butter, sushi...whatever, they all have their uses, ice cubes, champagne...)
toys (nipple clamps, whips, paddles, vibrators, those rolling wheels, whatever they're called, that you use for pizza and stuff, plugs, dildos, different salves, enema kit, strap ons...)
fisting (hide the knuckles *chuckles*)
breath-play (strangulation and the kind)
water sports (some people like pee in the most unexpected places)
beastiality (dogs, horses, snakes, what have yous...)
incest
double-penetration (either in the same place or one in the mouth)
voyeurism
threesomes, moresomes (orgies)
fire play (some people like a lot of pain)
candle-wax
exhibitionism
sharing with strangers, friends etc
blood-play
All right, now I'm running out of ideas, though I've still probably missed a few. Now, spend a moment feeling shocked, then go, have fun.
