The person who came to visit us today is Yuika, a day trader. Due to her job, she is in a world where she has to constantly gather information, so she has an intellectual atmosphere. She doesn't currently have a boyfriend and doesn't seem to have any particular aspirations. Even so, her sexual desire cannot be suppressed. She seems to be interested in naughty things and applied out of curiosity. Yuika says that she is nervous, but there is something about Yuka that makes her feel relaxed. She says she has never masturbated before, so I gave her an electric massager and asked her to show me how to masturbate. She twitched her legs at the first sensation and seemed embarrassed, but she felt it properly. It seems that it is. I lifted her hips and let her cum lightly.
