A work that lets you experience just how much your heart rate spikes in the ultimate situation—excreting while being humiliated in front of others. Heart rate is constantly displayed, allowing detailed observation not only during defecation but also at moments like taking off underwear or exposing the crotch. Starting while already feeling the urge to pee, the video realistically captures the trembling anus struggling to hold back, as well as instances of involuntary leakage without permission. Scenes unfold of girls peeing themselves while crying out "No! No!" in overwhelming shame, others defecating in tears, lightning-fast bowel movements, and grotesque pooping by a half-Caucasian beauty—offering a wide range of intense moments. The shocking experience of defecating in front of others for the first time can be fully felt alongside real-time heart rate changes. [Sakura] One after another, ping-pong-sized fecal stones drop with a plop… “No! Don’t look!!” Her older sister’s desperate scream is in vain as, without pause, a wet squelch erupts—splurt! splurt! splurt! “This is the worst (angry).” [Aki] Her struggle with her first-ever enema is captured in vivid detail from a lower camera angle. Before she can even process the aftermath, thick feces are forcefully expelled as her buttocks are spread apart, tears faintly forming in her eyes. [Eri] An older sister with peach-shaped buttocks and an anime-like voice. Despite her cute tone, the vulgar, foul-smelling feces she strains out are so disgusting she gags. Trying to end it quickly out of shame, she ultimately cannot resist the continuing waves of bowel urgency. [Emili] An extremely cute half-Caucasian girl. After a thick, lumpy, massive stool emerges from her swollen anus, she piles on additional defecations, further soiling her already dirty rear. When she shares her thoughts on the project, her heart rate hits a shocking 123 bpm! (Haketaiya) ※ Facial exposure in main video.
