Debuting from One's Factory this fall is Mariko Shiraishi, who has a beautiful face, well-proportioned limbs, and F-cup beautiful big breasts! Director Katsuyuki Hasegawa uncovers her hidden M nature, saying, "I like sex that can be blamed!" Her M nature blooms one after another for each scene, such as the expression of shame when she licks a man's asshole for the first time, and the head is pressed down and she desperately serves! Enjoy plenty of real masochism in your debut work!
