THTP-083 Incestuous SM record between siblings

The editorial department receives submissions from various enthusiasts. While each one is heartfelt, this work includes a submission from siblings who have entered into a forbidden relationship. The sister has an exemplary background; she excelled in both academics and sports since her childhood, attended one of the top girls' schools in her hometown, graduated from university, and after working at a company where she fell in love with a colleague, got married. The brother, however, had trouble with classmates during his time at ● School, dropped out due to truancy, and still lives at home with his parents. He is what you might call a 'hikikomori.'
The two engaged in a sexual relationship that evolved into an SM dynamic. The brother treats the sister as his slave●, but there are times when the sister blames the brother. In their inseparable bloodline, this is a record of the forbidden desires of an incestuous SM relationship.
