AGMX-109 Reiwa Beroro Observation Guide vol.4

"Just using the tongue can make you feel good" This urban legend is whispered about, and to investigate this rumor, women were gathered under the name of parts models. Their tongues varied in length, color, and shape, each unique. Observing them with bananas, transparent dildos, and electric massagers! The five amateur women gathered this time had varying ages and occupations. Removing their masks revealed distinctive lips, and from there peeked moist pink tongues. Is the rumor true? Can you really orgasm by having an electric massager on your tongue?!
