Ayaka has been keeping a secret from her husband—after over ten years of a sexless marriage, she's beginning to feel guilty about the betrayal. Her children are now adults, and she works as an office clerk at a transport company. She's never had sex before and has no casual partners. Now, for the first time in ages, she reunites physically with her husband. Nervous and timid in her demeanor, when she undresses, she reveals surprisingly erotic lingerie—the contrast only heightens the excitement. Yet throughout, she feels deep guilt toward her husband, unable to make proper eye contact until the end. Still, I creampie her. Maybe this will reach her heart somehow? Filled with emotion—on the verge of tears—this is sex as confession.
