[THTP-083] Records of brother and sister incest SM

The editorial department receives submissions from various enthusiasts. All of them are compelling, but in this work, we have recorded the posts of brothers and sisters who have entered into a forbidden relationship. My sister has an exemplary background, excelled in studies and sports from a young age, went to a girls' school, one of the best preparatory schools in her hometown, and got married after a workplace romance at the company where she got a job after graduating from university. ● My older brother had trouble with his classmates when he was at school, dropped out of school while refusing to go to school, and still lives with his parents at his parents' house. It is the so-called "hikikomori". The two entered into a sexual relationship, which also developed into an SM relationship. My brother makes my sister a guy, but there was a time when my sister blamed my brother. It is a forbidden record of brother and sister SM devouring each other's desires in the blood that does not separate.
