The latest work of Mariko Uchida, a beautiful morning-picking girl with a cute confused smile as she looks down shyly, inserts a thermometer... In the bed of the girls' dormitory, a female senior plays tricks on her bust, navel, crotch, thighs, and a-hole.Mariko is invited to climax...she is dragged around in handcuffs and a collar, and is made to crawl on all fours on the floor...she urinates...she is embarrassed and begins to feel it, so she holds back...she is definitely a masochist...
