Porn stars Mori Hinako and Yayoi Mizuki each design their own genuine Christmas date, believing they will be seeing different men. The hidden twist is that both dates are with the same guy. While one woman shops for a surprise gift, he secretly has sex with the other. Once his two-timing is exposed, the women join forces for a playful punishment: an indulgent harem session packed with sperm-draining sex and creampies.
