Recommending Female helper

[Pretentious Goblin]

Looking for games where a male MC has sex with multiple female characters (not necessarily all at once, and not necessarily as part of a relationship). It can be consensual, rape or anything in between. But there has to be a female ally that knowingly helps make some of the sex happen. She can be a romantic partner, a FWB, a mind-slave, a dommy mistress, a sister-in-arms, a hunchback lab assistant, a succubus, whatever, as long as she helps MC bang others.

The helper does not have to be sexable herself or take any part in the acts, in fact it might be interesting to find such a game where the helper herself is untouchable. Even better if it's a game where you play as the helper, though I doubt this exists. NTR games where this happens (female character facilitates cheating) are good too.

Overwhored - "Tower Mistress" and many of the girls post-mindbreak.
The Last Sovereign - too many to name
Harem Collector - party members who assist in combat, possibly others.
Virgin Invader - "recruitable" girls
Goblin Walker - MC's allies
Nano-Control - MC's mom helps corrupt his sister, among various other examples
News Desk - Emily actively participates in Tiffany's corruption, Tiffany can become an asset
Henteria Chronicles Ch. 2 - NTR perspective, another girl helps one of the stealers
Fort of Chains - female slavers
Hail Dicktator - the lesbian (?) bartender iirc
VenusBlood strategy games - "recruitable" allies
Harem - existing harem members help "recruit" others
Corrupted Saviors - defeated Chosen can be trained and used against later teams
Tyrant Quest - various characters
Wonder Slave Trainer - Harley does much of the sexual training of Wonder Woman. Others help too.
The Headmaster - PE teacher helps discipline students, science teacher helps hack a student's computer. Probably more later.
iNSight of you - various girls help in corrupting the antagonist, some more hands-on than others.
Soldier's Life - ditto
Behind the Doom - several characters

Cheating female MC

Star Knightess Aura - cheating female MC corrupted/brainwashed by her frenemy
Alansya Chronicles - cheating female MC corrupted by her twin sister

This is a favorite mechanic of mine, though it can be hard to locate games that have it since there's no tag for it. I tend to refer to it as co-corruption.

Anyway, some of my most liked games that have this (pretty much all of these are incest harem games, sorry if that's not your thing):

Parental Love - your sister helps you to corrupt other girls in the family
Neko Paradise - your wife begins to help you with some of the girls later in the game
My New Family - Sandra is the one who pushes you to date other women
My New Memories - still early on in development but it looks like the wife might be a big part of you getting other girls
Once a Porn a Time - no incest, interesting story idea anyway: you and Tinker Bell work together to corrupt android girls
Apartment #69 - the Mom seems to be helping the MC from behind the scenes as he slowly corrupts his sisters
Midlife Crisis - the wife eventually starts to help you with other girls I think
Blackheart Hotel - not much incest, Paige helps you rape and control other girls
Single Again - Becca is the mastermind trying to get all the girls to you

Nice, I'm guessing these are all VNs but I may check out some of them.

By "polyamorous" in this case, I mean just a male that has sex with multiple females over the course of the game. It can be consensual, rape or anything in between. But there has to be a female ally that knowingly helps make it happen. She can be a romantic partner, a FWB, a mind-slave, a dommy mistress, a hunchback lab assistant, a succubus, whatever, as long as she helps MC bang others. She does not have to be sexable herself or take any part in the acts, in fact it might be interesting to find such a game where the helper herself is untouchable. Even better if it's a game where you play as the helper, though I doubt this exists. NTR games where this happens (female character facilitates cheating) are good too.

Overwhored - "Tower Mistress" and all the girls post-mindbreak, really.
The Last Sovereign - too many to name
Harem Collector - party members who assist in combat, possibly others.
Virgin Invader - "recruitable" girls
Goblin Walker - MC's allies
Nano-Control - MC's mom helps corrupt his sister
Henteria Chronicles Ch. 2 - NTR perspective, another girl helps one of the stealers
Fort of Chains - female slavers
Hail Dicktator - the lesbian (?) bartender iirc
VenusBlood strategy games - "recruitable" allies
Star Knightess Aura - cheating female MC corrupted/mind-controlled by her frenemy
Alansya Chronicles - cheating female MC corrupted by her twin sister

then that would be a harem/polygamy not polyamorous as polyamorous is basically an open relationship were everyone fucks around with whoever they want(not a one man multiple girls relationship) the only difference between it and a open relationship is it needs consent with all people involved

I didn't know what term to use exactly. No ongoing relationship is needed at all, it can be ONS. I think I'll rephrase the OP to avoid confusion.

Sandboxes with "otherworldly" helpers:
Long Live the Princess - Belle
Time Loop Hunter - Cas
SexNote - Brixxida
This Romantic World - Switch

Monster Girl Club Bitfrost has a succubus style assistant for running your brothel that is romancable.

A large theme of my harem game is that the girls all become friends and encourage each other to push their boundaries. Everything from doing each other's makeup for dates with the MC to teaching them a new BDSM technique. But it definitely leans on the wholesome side and is a standard VN Sandbox, so be advised.

Harem Hotel by Runey has Maria who is helpful with the other girls … to a greater or lesser degree.

Pretty much all the girls in Harem Hotel are helpful in creating the mc's harem.

 

[Strike-10]

True!! … but Maria is “next level” both for her own benefit & the MCs benefit …
Maria is the catalyst for “level ups” … think moon scene, Kali scene, even the scenes with Lin,droid, & Autumn … Maria is the “corrupter” or “supporter” for additional lots of corruption of X persons

Added links and 4 new games.

High School of Succubus is a classic trainer style game where you play as a female succubus corrupting a female MC. Lots of female-female corruption, the succubus has the MC corrupt her friends, friends corrupt the MC, so on and so forth. Save often because it can get buggy at times and there is no gallery, but tons of content and has some great corruption.

This wasn't on my radar at all, probably because the presentation screams "teenage girl target audience". I'm guessing the corruption is pretty soft, but I may check it out anyway, thanks.

It's nothing crazy by any means but gloryhole, DP, light pet play, and a couple solid mistresses elevate it above pure vanilla sex imo.

 

[Reppie13]

Probably late to the party but in WVM, mc's girlfriend is doing everything in her power to have the mc shove his cock in all the girls in the school pretty much.
Unless I misunderstood something, in that case, disregard this.

No, that's exactly what I meant, thanks.

Pretentious Goblin thanks a lot for linking this thread, this was pretty much exactly what I was looking for. Still haven't quite found a game that's scratching the itch. I'm a bit picky because I also don't really love drawn anime style / honey select games, which narrows my options. But it's nice to see there's a group of people who are still on the hunt for this niche.

Don't really have many suggestions of my own, but:

College Daze: Very large HTML game with a lot of variation and routes. You can play with cheats, which basically makes it an CYOA game. There's a lot of helper content with multiple LIs involving some variation of love, magic, or blackmail.

Guilty Pleasure: One sister has a family kink and actively tries to bring the other sister into the mix, ultimately headed towards mom as well. Good idea, the storyline just moves very slowly due to small (albeit consistent) updates.

Raptus: MC has some sort of mental disorder and is prone to rape and violence. His sister and his therapist actively help him in his crimes.
