Thanks to Risa’s strict but reliable support, the shop successfully reopens. One day, the protagonist discovers a special solvent created by his grandfather. While chatting after work, Risa casually starts changing her clothes in front of him. Shocked, the protagonist accidentally spills the solvent on her. As he nervously apologizes, Risa’s demeanor changes dramatically, becoming seductive. With her body burning with desire, she approaches him and, with her ample chest exposed, whispers, “Please… could you satisfy me?” And so begins an unexpected scene of passion!
