The lively tanned girl Riko-chan visits homes to help troubled men improve premature ejaculation! The concept is innovative: if they can hold back ejaculation, they get a reward of oral sex. I actually watched it, and Riko-chan's toned body is amazing, with excellent fellatio skills. It's content only a born semen-loving actress could pull off, and her earnest effort to fellate thick shafts was admirable. She drinks so much semen, I worry she might upset her stomach. Her body shows strict, stoic training, making her incredibly sexy and a praiseworthy actress. The director laments that it doesn't work out, but that adds to the fun, making it a highly entertaining work!
