Quinn

Quinn is introduced in Part 2 and is the only human hermaphrodite in the game possessing both male and female genitals.

She is a work partner to Jessica and after she has been infested she will show you her secret that she is a hermaphrodite and the Jessica doesn't know.

Getting Mindfucked
If you get mindfucked by once a day by her alone the following events happen;
 * 1) You are obedient to Quinn, and want to let her ejaculate inside you again.
 * 2) *You receive a phone call at home after school - it's Quinn. She'll be round in 5 minutes to have sex with you.
 * 3) Wouldn't it be nice if Jessica joined you? You could both worship Quinn's dick together.
 * 4) One more session and you don't think you'll be able to control yourself anymore.
 * 5) Quinn Breeder Victory

Bad End
This is the new normal. Every day, Quinn pumps her seed into both you and Jessica in a passionate threesome. You and Jessica also inseminate each other in every hole except for your neck vaginas, which are the exclusive property of your master. The rest of the day is spent doing tasks for Quinn and being a good, obedient breeding slave for parasites.

Quinn quickly subjugates the rest of her workplace and your household. She keeps you and Jessica as a pair though - her personal concubines. Slowly, her empire spreads out. Her corrupted cock only gets more demanding as her power grows. It seems her lust cannot be sated - the town gets infected, then the surrounding countryside. You quickly lose track of the larger picture. The only thing you are aware of is that there always seems to be new infected and infested people introduced into her personal growing harem. People you willingly service in every imaginable way. Your body, along with Jessica's, turn into perfectly proportioned optimal breeding vessels. All day long, you dream of Quinn's dick stirring around inside your head.

Trivia
Quinn begins with a high perversion level. This means if Jessica is infected early it is very likely that by the time she becomes infested and takes the player to Quinn's Workplace she will have perverted Quinn enough that Quinn will try to engage in sex on the first meeting without even going to the cafe. The game describes her relationship with Jessica as "acidic" and that they often take shots at each other's insecurities in casual conversation. Seemingly Quinn has a desire to get the better of Jessica as is shown in the Bad End where she uses Chloe to enslave her mother. It is possible that because of this complicated relationship that Quinn decides to make sexual advances on Chloe, Jessica's child, when they meet at the cafe.

During the encounter in the cafe bathroom, Chloe goes slowly at first not wanting to scare off Quinn. She starts by complimenting her figure until the preamble is cut short by Quinn revealing her large penis. After her first ejaculation Quinn seems unaffected and is able to rapidly fill Chloe a second time. Chloe remarks that it is likely due to her unique biology. The ordeal takes a suspicious amount of time and Jessica who was left at the table to flirt with the waiter, ignores it anyway.

Though not directly stated it is implied that Quinn and Jessica work at a bank as during the special session Quinn moves money from multiple accounts into Chet/Chloe's.

Due to having a penis Quinn is quite sexually aggressive, especially being aroused by the thought of impregnating her partner. At the same time she often hesitates both in social situations as well as during sex even trying to pull out during her Bad End. This could be due in part to her relationship with her workmate Jessica. They constantly exchange remarks targeting the others insecurities and it seems Jessica may get the better of it. Quinn's regret over molesting Chloe as well as her submissiveness during the special session seem to point to this. Quinn is so shaken by the possibility of Jessica knowing about her and Chloe that the game says she reassess her life goals.
