Holiday with My Busty Cousin

After a decade apart, cousins Ken and Tomo finally reunite during the holiday season. No longer children, they have both grown into adulthood, with Tomo now possessing a strikingly mature figure. The time apart has done nothing to dull their connection; instead, they quickly rediscover their bond and fall back into an easy, comfortable closeness. As the festive days unfold, their mutual affection deepens rapidly, ultimately leading them to cross a forbidden line and give in to their hidden desires. However, their secret romance does not go unnoticed. Ken’s mischievous younger sister secretly observes their intimate encounter, uncovering the taboo relationship between the two cousins. Rather than simply keeping this discovery to herself, she reveals a devilish side, quietly formulating plans to intervene. Determined to sabotage their budding romance, she is willing to go to extraordinary lengths to ensure that the love blossoming between Ken and Tomo never progresses any further. What begins as a quiet holiday reunion soon transforms into a tense struggle, as the couple must navigate the dangerous obstacles placed by a sibling who knows far too much.
