The end of the year party season is finally upon us. The annual end of the year party is being held at this hotel health club in Nukibukuro, Tokyo, an erotic battleground with a plethora of brothels. Participants are the busty ladies with over 100cm breasts, the club staff, and some regulars. As the alcohol starts to flow and people get drunk, it's time for some free time. There's a year-end busty blowjob contest, a busty titty fucking appreciation festival, a year-end busty harem mat, and... The last busty orgy of the year is about to begin.
