MIAA-805 My younger sister, who suddenly got married due to my father's remarriage, and I unexpectedly ended up sharing a room in a trash room. Hikage Hinata can't stand the 3D woman and can't pull out and creampied her

I'm a 2D nerd and I'm holed up in my garbage room. Then my parents remarried and suddenly I had a younger sister, and we unexpectedly ended up sharing a room! I felt a 3D girl up close for the first time, and despite my confusion, I got a huge erection! I spilled my lust-covered semen onto her sleeping head... Hikage can't stand the delicious smell, and he crosses the line between brother and sister by continuously ejaculating without pulling out. dirt
