Yumika and Hina, who live in the same apartment, are mom friends belonging to a certain circle. The content of this circle's activities is — bluntly put, sex!!! They invite handsome men, plumbers, neighbor students into their room and devour them from front to back, top to bottom, 360 degrees!!! Every hole in their body, every protrusion, they suck, lick, and slurp with loud noises!!! Witness the orgies of these sex-crazed monster parents fighting over cocks with smiles on their faces!!!
