And let the List begin!!
The following is not organized in any specific matter.. these situations and actions do not apply to all hentai series. Feel free to leave any cliches in the comments :)

It's either a small story encircling a relationship, adventures of a fantasy land, or just a rape spree.
During sexual acts, the woman, if there is one, must always have her shirt or gown pulled up high enough to expose her breasts. (not necessarily bouncing)
If you wanna rape someone, do it in the park-!
Tentacles. (haven't seen one yet-- but, hopefully it'll bore me)
In an incestuous relationship, someone is gonna pick another relative member.. not you.
If you're sent to a training camp to overcome sexual desires... it takes sex to ex sex. Clear enough?
The jealous [little] sister.
The only time a man will smile during sex is during rape. Sadly, I'm not sure about yaoi situations.
A guy will always be the one controlling that sex toy in you, my lady. Unless it's a yuri, then, -both ladies have the pleasure of doing so.-
from Lover in Law (<3333!)
Your husband's dead, so... just keep fucking in life!!
The greedy, [evil] mom.
Sex storytelling-- one popular way to turn on your man.
The mom who kills someone.. oh yeah, School Days was soo influential.
from: Taboo Charming Mother
Drugs... for temptation and getting hard ~ oh yeah, this one's a weak one.
Shower scenes-- your fantasy just got real.
Guy (or gal?) who just 'can't hold onto his feelings anymore!'
Sharing.. is caring. It's actually not.
from Lover in Law.
Thankfully, nobody was a scheming envy chick .
One guy... with all the big ladies ~ are harems starting to get old now??
If you have double-letter breasts, you're turned on like that. *snap*
Guys with glasses.. all of 'em got an evil side. X)
from Sextra Credit (the dub is SOOO American)
