The BEST collection of all three works and corners from the "Fertilization Inn" series is finally complete! There are sisters who run a guesthouse and still carry on a strange custom from long ago... One female mates with several males, improving her female qualities and giving birth to excellent children. This is an orgy work featuring six overwhelmingly beautiful big-breasted sisters who are educated to be women who attract and please men, and who seek each other's excellent genes! Enjoy eight hours of ejaculation-filled fun as your sperm is extracted!
