If you would like to see your The Sim 4 character bound in a pillory and getting railed from behind or get sucked off backwards by a sexy green ghost, WickedWhims (NSFW!) is the mod for you.
"This very much unofficial mod adds specific sex acts, like anal, and smaller details, like letting players decide where to come," according to a Kotaku interview (NSFW!!!) with its creator, Turbodriver. It's a good read. Turbodriver figured there'd be demand for horny Sims mods featuring hardcore sex acts, saw that there were none, and leapt at the business opportunity. It's now his full-time job, thanks to 1,009 patrons donating paying out almost $4,200 per months (nice!).
He also talks about the difficulties in being, "the person that decides what is right and what is wrong," when it comes to others' sexual fantasies they're pining to see represented in the mod (for example, getting sucked off backwards by a sexy green ghost?), among other things. Like I said, give it a read, if only because all the GIFs of Sims sucking and fucking are hilarious.read more
