My First Time Is With My Brother... A Pure Sister Gets Corrupted! Volume 1

“We shouldn’t have, but...I went all the way with my little brother” ---- Shoryu, Shizuku’s younger brother, shows up unexpectedly at her house where she lives alone. He said he needs to stay at her place for a while. Not having heard anything in advance, she says that she has nothing, not even a futon, for her brother to sleep on. “We can just sleep together.”, says Shoryu. The two are in-laws, sleeping in the same futon...feeling excited while trying to sleep, a half-asleep Shoryu starts to rub Shizuku’s breasts, stimulating her nipples, Shizuku begins to writhe while trying to hold back her voice. Finally she can’t handle it, and starts to play with her wet p*ssy...she cums while rubbing on her little brother’s chest. The next day, while masturbating in the shower thinking about the previous night, Shoryu comes into the shower and says “Let me wash my d*ck inside my big sister” My first time is with my brother!?
