Even the furries get love here!


To cure herself of a drug’s side effect, an alchemist must collect the semen of various men while her little brother and lover watches in Why My Alchemist Sisters Collect Cum - Baby Making Through Cheating SEX!

Developed by Ore Teki Shikou, Why My Alchemist Sisters Collect Cum - Baby Making Through Cheating SEX! Is an RPG Maker game where two incestuous sisters cheat on their younger brothers with random men. The first couple of siblings are Wendy, the alchemist, and Roy, the waiter. When Wendy worries that a bunny girl will take Roy away from her, she concocts a drug to make her more alluring, but she screws up. Instead, the drug makes Wendy more horny and lewd. While searching for a cure, a mysterious figure tells Wendy to collect semen from a variety of men. She isn’t sure if the figure could be trusted, but with no other leads, Wendy begins her quest for semen. As for Roy, all he can do is watch on as his beloved big sister takes dick from many, many unknown men.

The second couple is a warrior and mage duo. Ellie is a warrior who became friends with Wendy because of their mutual love for their little brothers. She and her brother/lover Rick travel to Wendy’s town to help her with semen collecting mission. Ellie is more experienced with sleeping with random men due to prostituting herself while adventuring with Rick, so she will act as an advisor to Wendy and help ease the drug's symptoms. Rick doesn’t mind Ellie doing this for he believes that he still has a place in her heart. When Ellie starts seeing her relationship with Wendy as something caused by fate, she may have feelings that go beyond mere friendship.

The main objective is to have sex with many different men and get pregnant. Wendy and Ellie have womb integrity and they will only get pregnant when a man creampies in them while her womb integrity is at zero. You will always have the option to choose whether you want him to cum inside or outside.

To give you even more control over who your baby daddy is, there is a Semen Overwriting System. Before you go to bed, you can choose who becomes the father of your child. This lets you plan out all your raunchy sexcapades while concealing any evidence of cheating. When it’s time for the baby to be born, you can either give birth the regular way, or hold a birthing show and earn money as an audience watches.

You will be able to create high ranking items using alchemy. Materials can include cum, urine, public hair, breast milk, and more. You can make items such as a swimsuit or a cum dildo. There are also items you can buy in the store. Contraceptives will reset womb integrity and fertility drugs will set the womb integrity to one. Some items can even trigger H-scenes or other events. You can even trigger a scene where you can buy a pregnancy test and tell the man who impregnated you that he’s the father.
