If you have given Jimm the Panties and don't get the option to summon a succubus maybe try sleeping and interacting with the summoning circle the next day.
You can summon Meril the succubus you fought earlier at the same summoning circle where you summon Jimm... you can do this once everyday, you can summon Jimm and watch him fuck a succubus/Preggo-succubus/Futa-Succubus/Prego-futa-succubus to raise your lust and you can summon meril to lower your lust by letting her ride you or ask for a handjob.
If you have high lust then you can chose to suck off the Futa behind the Tavern at night... no CG for this scene last time I checked. If you lose to the Bandit ass raping Julliet he will Ass rape Krowley. At evening time in the forest outside the town to the east/right of the map above the path that leads to the waterfall where Finna bathes... There is a small clearing with a campfire and a barrel... an orc shows up there in the evening and if you keep drinking with him eventually Krowley passes out and the orc ass fucks him.
There's a hunting event called a Glade or something where you meet the Futa and Rose the alchemist... if you go through the event and win you have the option to get a BJ from Rose or Eric ... if you go through the event and lose then the Futa fucks Eric's ass and you fuck hers. Also if you read the text then a LOT of the damn monsters keep poking Krowley's butthole. Tentacles especially do a lot of gay stuff.
It seems most of the Elven women you come across are futa's so there's gonna be a lot more of it in the future x_x
D: Depends on how you look at it I guess what your definition of gender is and all that crap... You don't wanna hop down that rabbit hole ... just enjoy the pretty pictures. @_@ ... It's all 0's and 1's ... ... ... Really hope we get some decent content with Jaina soon. and wish Eric had a stupid fem face like Krowley...
Also Jaina the futa chick is all about fucking tight goblin asses... Using a spell to give her a vag would drastically alter her character, Or just piss her off. .. ... Imagine you cast that spell on her an she shows up at church instead of the tavern next day in a big frilly pink dress. XD
