Sakuma Tsuna says this is her first time doing such a substantial enema work. She stoically endures the continuous milk enemas, which cause her to suddenly writhe in agony, but the repeated enema squirting and extra-thick thrusts eventually bring her to an unbearable pleasure, and she climaxes, gushing with intestinal juices!!! "The feeling of exhilaration when I let it out is incredible."
