Three girls participate in a two-day, one-night retreat, enduring a strictly controlled environment. Forced into situations where they cannot use the toilet, they express feelings of humiliation, anxiety, and childish dependency. The story unfolds under extreme conditions, featuring episodes of incontinence, diaper use, and enemas. Produced by Amaenbo Education Promotion Society—the team behind Sanwa Publishing's "Oshioki Club" and "Omorashi Club"—this acclaimed classic, which helped pioneer the genre, now returns in a complete reissue. This is a rare, invaluable footage capturing the ultimate in humiliation.
