[THTP-083] Brother and sister play SM record (Censored)

Posts are sent to the editorial department from various enthusiasts. All of them are compelling, but in this work, we have recorded the posts of brothers and sisters who have a taboo relationship. My sister has an exemplary career, excelling in both studies and sports since she was a girl, went on to one of the most prestigious schools for girls in the area, and after graduating from university, got married at the company where she got a job after a workplace romance. My older brother had troubles with his classmates when he was in school, dropped out without attending school, and still lives at home with his parents. This is the so-called “withdrawal”. The two had a sexual relationship, which developed into an SM relationship. My brother has my sister as a slave, but there was a time when my sister blamed my brother. It is a forbidden record of brother and sister SM who devour each other's desires in the inseparable blood.
