A pure and cute beautiful girl with almost no romantic experience, that's Umi-chan. In their very first sex encounter right after meeting, her overly sensitive body instantly switches into full serious mode. It vividly depicts how she fully receives the man's hot lust, moaning heavily with ejaculation on her tongue, trembling her slender body and cumming over and over again. "I never knew sex could feel this good..." — A documentary work that realistically records the genuine pleasure a pure beautiful girl experiences for the first time. *This work does not feature any performers under the age of 18.
