Ishigami, working for a large advertising company, is dating Ruisa, who works as a receptionist at the same company. However, Ishigami, in love with Luisa, is disappointed with Luisa every day, as she refuses to let him live even though she is engaged. One day, the boss of the company and the seniors invite 'Ruisa' to preview a comfortable trip, but... A perverse NTR trend awakens in a hot spring inn and a thick circle is repeated in a cloudy bath filled with semen.
