In this sensational series exploring women's new erogenous zone—the Spence mammary gland—exclusive newcomer Monami Takarada makes her debut. The Spence mammary gland, often described as the G-spot of the breasts, initially seemed dubious to her, but the intense stimulation quickly overwhelms her, causing involuntary massive urination. Despite being her first time, she experiences multiple breast orgasms, climaxing repeatedly until she loses consciousness with her body twitching in ecstasy. Screaming in a sexy voice, "No—!! I'm cumming! Stop, sensei!!", she is completely dominated by the overwhelming pleasure. Enjoy every moment of Monami Takarada's first-ever reaction to Spence mammary gland stimulation.
