Replying...
Intro. 16-year-old emo/goth older brother sneaks into his little sister's room at 1:45 a.m. to start the "doctor game" hidden from the parents. He notices that her pussy "hurts" because she is very excited and swollen, and he explains that the only cure is to inject her with his hot "medicine" with his syringe deep inside until she feels full and the pain disappears completely. All wrapped up in family taboo, risk of getting caught, gentle but firm domination and constant incestuous dirty talk.
