[Requests Accepted] [アンモライト] クーデレ姉ちゃん観察日記 ～秘密のオナニー、盗撮しちゃいました～ [VJ012450]

■□■Story■□■ ●Younger Brother's Side I have an older sister. Usually, she is quiet and aloof, like a cool, downer-type heroine from an anime, named "Rikka." (If this were in 2D, it would be so cute... Sigh...) One day, something happened. (Was my room always like this??) I can't pinpoint exactly what it is, but there's a vague sense of discomfort... So, after some events, I decided to observe my room closely. (Is something showing up?) When I played it back, I was met with a shocking sight...! ●Older Sister's Side I have a younger brother named "Haruto." I love him so much that I often act indifferent. (………………Today, Haruto is not home) After checking the entire house again, I entered Haruto's room. (…Haruto's scent♪♪) I undressed and got naked, just like "usual." Then, while feeling my brother's traces all over my body, I reached out to my feminine parts, just like "usual"... Characters ●Jinsei Rikka (CV: Amamori Riko) The protagonist "Haruto's" older sister. Petite with a large bust. Calm, quiet, and speaks little. She treats Haruto coldly and indifferently. However, she is actually quite the bro-con. She loves him so much that when the family is away, she sneaks into Haruto's room to enjoy various things. She is a virgin. “...What?” ●Kusunoki Eriko (CV: Hazuki Akari) Rikka's friend. She appears pure, serious, and kind. “I don't know what will happen, but just make sure you won't regret it, okay?”
