Takaaki assumes his mother’s best friend must be just another middle-aged woman, but Hikari shatters that prejudice with her beautiful face and voluptuous breasts. Desperate to get closer to a woman whose body perfectly matches his tastes, the awkward Takaaki struggles to make conversation and finally steals her panties to masturbate with. She catches him, but instead of becoming angry, Hikari responds with a tender kiss and draws him into an unexpected intimate encounter.
