Recently, my outgoing sister got a boyfriend and begged me, 'If it's found out that my first time was at a love hotel, my image will be ruined! Big brother, take me to a love hotel!' So I decided to take her to a nearby love hotel to teach her about society... Before I knew it, my sister had become a 'woman's body'! Even though I knew it was absolutely wrong, I lost all reason! No condom, and I ejaculated thick, concentrated semen inside her.
