Honestly, too many for me to remember off the top of my head... but just as a quick "what I can remember right now" list, CK contains: vaginal, oral, anal, handjob, blowjob, pregnancy, twins, ahegao, bdsm, netori (MC steals another guy's girl - NOT the other way around!), corruption, cosplay, creampies, exhibitionism, harem, lactation, threesomes (mff), milfs, mind control, monster girls, spanking and voyeurism.
And almost certainly a few more I'm forgetting right now, too. Hope that helps! :)
