Shocked to learn his beloved sister has been working in the sex industry, the brother confirms it online and heads to her shop. Inside, he requests the "blindfold course" and specifically asks for his sister. In the room, he finds his blindfolded sister lying on the bed. Trying not to be recognized, he starts with gentle touches. When he undresses her and sees her breasts up close for the first time, he's overwhelmed by their beauty. Removing her lingerie, he begins licking her sparkling nipples while reaching down to touch her intimate area. Overcome by sensation, he loses control and despite the brothel's strict no-penetration rule, he ultimately thrusts inside her.
