[Requests Accepted] [アンモライト] 友達の妹はオシオキ希望 ～愛と情熱のお尻ぺんぺん～ [VJ015804]

■Story "If only my big brother would spank me, I could focus on studying..." It's the middle of summer vacation. While I was at a loss, my childhood friend asked me to tutor his sister while he was away on a club training camp. I've spent so much time with my childhood friend's sister, Yuki, that we feel like real siblings. Before I knew it, she started calling me "big brother," and I no longer felt any discomfort with it. However, Yuki has no motivation to study at all... Yesterday she ran away, and today she was slumped over her study desk, but then she lifted her butt and thrust it out, challenging me to spank her. As I became acutely aware of my manhood stiffening in front of a beautiful girl's rear, I, as her tutor, brought my hand down for a punishment. 登場キャラクター ● Yuki Tobita (CV: Moya Nono) The younger sister of my childhood friend, Toshiya.
