My older brother, who knew absolutely nothing about sex, suddenly got a girlfriend, and that's when I realized my own feelings. My younger sister teaches me about adolescence and sex education. Tanaka Mihiro's Birth KNIP-008

Upon learning that her socially awkward older brother has found a long-awaited girlfriend, younger sister Mihiro can't be genuinely happy and gradually realizes her own feelings… "I… I like older brother…" The day before their date, she says, "Big brother, you'll be hated if you ejaculate right away. I'll be your practice table." It starts with passionate kisses, foot fetishes, deep throat blowjobs, and tongue ejaculation, then "No condom allowed," "Use Mihiro's cunt as you please," and "Ejaculate whenever you want." Shaking her disproportionately large buttocks, she gives her brother a sex education lesson. A completely subjective, loving five-shot ejaculation scene! ※Some scenes have been processed using generated AI.
