Popular series newcomer Sona Kon makes her debut! Kon jokingly teased her unpopular virgin brother. Mistaking the joke for a genuine invitation, her brother immediately penetrated his sister right after their parents left. Although Kon reached orgasm from the sheer force, her inexperienced brother didn't notice and continued to thrust wildly. Despite reaching orgasm, the continuous pistoning chased after the pleasure, causing repeated orgasms. Unable to resist, she was made to cum multiple times until their parents returned home.
