[Requests Accepted] [アンモライト] お兄ちゃん、教えて…… ～義妹とヒミツの保健実習～ [VJ009815]

■□■Story■□■ It feels like just yesterday. "Teach me health and physical education using your body as a teaching material!" My sister, Yuri, who attends a prestigious nursing school. I thought she was smoothly progressing on her path to becoming a nurse, but apparently, "when it comes to male bodies, my mind goes completely blank." But using my body as a teaching material for practical lessons... is that really okay? Is it acceptable for siblings to do something like that? Even if we aren't blood-related... Before I could gather my thoughts, my sister came home. It seemed like she had completely forgotten about our promise from last night. I secretly breathed a sigh of relief. It seemed unlikely that she would actually be able to teach health and physical education. Just as I was feeling relieved... "Um... big brother. Tonight... can we have that health and physical education lesson...?" I found myself nodding in response to her words. What will happen tonight? Just thinking about it made my heart race... ■□■Characters■□■ ● Shiramune Yuri (CV: Miya Serien) T142 / B78 / W59 / H83 Kenichi's stepsister. Since their parents remarried, she has harbored a faint affection for Kenichi. As they live under the same roof, her subtle feelings have grown stronger, and to hide her emotions, she speaks in a blunt manner. At her age, she is very curious about matters related to sex. ● Shiramune Kenichi Yuri's stepbrother. He finds Yuri's blunt attitude, among other things, to be endearing.
