A bizarre twist unfolds as siblings face off in a baseball ken game with a high cash prize at stake! The older sister is Miho, and the younger brother is Ken, a virgin. Even upon their first meeting, they exchange slightly suggestive banter: "Getting hard just seeing your sister? lol" "No way, that wouldn't happen, haha." Yet, after this exchange, the brother is instantly fully erect when confronted with his sister's incredibly sexy body. They quickly retract their earlier words, clearly turned on by each other. Ignoring the so-called baseball ken match, they immediately escalate into sex. Overcome with passion, they indulge in creampie sex under the heated mood of "As long as it feels good, anything goes, right?" For the brother, losing his virginity to his sister's pussy becomes a uniquely thrilling experience—one he can't help but feel proud of. In the second round, things intensify even further, with more passionate exploration of the sister's body, ramping up the erotic tension. Um... could we continue this at home? lol
