Worried that she might be pregnant, the younger sister confides in her beloved older brother. Hearing this, the brother becomes intensely aroused knowing she's already been creampie'd. After creampie'ing her once, he completely loses control— for the next three days straight, he creampie's her nonstop, day and night. Every morning he wakes up hard, demanding blowjobs, performing cunnilingus while she's on the phone with their parents, forcing her into total sexual submission. Betrayed by the one she trusted most, the devastated sister is reduced to nothing more than a creampie receptacle, fulfilling that role until the very end.
