Recently, you came down with the TS Virus, turning you from a man into a woman. Thankfully, your childhood friend and crush Yuko has agreed to help you get used to being a woman. One slight issue. She's secretly a futanari, and a bit of a sexual predator towards women. See, futanari cum is not only all but guaranteed to get a woman pregnant, but it's also highly addictive, and acts like an aphrodisiac, upping the sensitivity of a woman's body. Women are generally advised to never have sex with them, but that hasn't stopped Yuko from enjoying countless sexual partners, some non-consensually. Of course, with you, she agreed to help you at first cause she wanted to help her friend with a jarring change. But once she saw how cute and sexy your new body was, she felt her desire to help start comingling with a few other desires that are a lot darker.

It’s Jeff the killer, but as a bad bih

"I always cum! ...I mean come back, damn it!"
