The butt is stroked like an unpleasant, and the defenseless chest is rubbed from behind. Rikako had encountered the first lewdness in her life. (Why do you have such an aunt?) Rikako was relaxed because she couldn't have a lewdness. That attitude stimulated the lewdness. (If you do more than that ... I can't stand it ... I hate it, in a place like this ...) If someone sees you feeling sick on a crowded train like this ... Rikako's body, which has become stuck due to shame and fear, is groped by her dirty fingers. The body that was frustrated with her husband without sex begins to react sensitively.
