Easiest way I found is with CoCEd, just go in and add the amount, length and girth you want. I think the game limits it at ten, but that should give you a good tentacle nest. Here's the link for CoCEd from the forums here:

I'd like to see more content for some of the NPC's like Beatrice Reasner, the mountee chick on Canadia, and some more done with the conflict with the Myrs.
IIEC that shouldn't be an issue as the game thinks you can just wrap that around your waist Saiyan style. Now, if you had ginormous balls that made things a little hard to walk, or multiple 50in.+ dongs, then there would be an issue. That's more of a 'too much of a good thing' thing,
If all else fails use CoCEd, that'll let you customize your characters genitalia. Limit on additional dicks is a total of 10. Here's the link:

I like a bigger ship (namely the one being built in Zheng Shi as it's already there) and some expansions to established characters. First would be Beatrice, when she's ready, then a way to get Kiro preggers and possibly recruited.
You are not the only one. I just hope that, once it's done and dusted, that Fen gives it it's proper priority. Adding Beatrice to my harem is something I am longing for!
If someone tried to screw with that I'd be upset. One thing I do wonder about is when will Fen give us the option to upgrade to a new ship, or, if we get Beatrice updated... maybe we can start our own Harem Fleet!
Yeah Gothamson, we have the dream first, then the fertility quest, then we can make babies with Beatrice. By the way, I've been a Dungeon crawler since I was six. Nice job on the Ilmater avatar.
