LF doujin - stepfather

From what I remember of the doujin, it was published this year. I saw it on Hitomi.la in English, but I haven't been able to find it again (it seems like it was taken down). Its first page was in color, rest monochromstic, and I'm not entirely sure, but it might be a one-shot.

The story starts by showing an emo-styled stepdaughter (piercings and black clothing) living with her fat stepfather. The stepdaughter has sex with the stepfather planning to expose him to her mother one day so she can get rid of him. However, as in most doujins, the stepfather creampies her, and the daughter ends up falling in love and becoming addicted to having sex with him.

On the other hand, the story also shows that the stepdaughter has a boyfriend, who is hated by the mother. However, later on, it's revealed that in her free time, the mother goes to an abandoned garage or warehouse to meet her daughter's boyfriend to have sex.

Finally, at the end of the doujin, the mother reveals the NTR to her daughter. If I remember correctly, the daughter is getting fucked by the stepfather while the mother is getting fucked by the boyfriend, with everything happening in the same room. In the end, the stepfather gets both of them pregnant.
