Madoka Uchimura appears in this video. Her chest measures around 90cm, with a cup size between E and F. Her gorgeous breasts are first measured using her tongue, which is 4.5cm long—quite lengthy, and Madoka giggles, saying, "I stuck it out so far!" Her slightly shy demeanor is adorable. When she removes her bathrobe, her large, impressive breasts are fully exposed. Both areolas measure 4.5cm as well, matching the length of her tongue and creating a pleasing balance. Her nipples are also measured, and being touched there feels unbearably sensitive. When her clitoris is stimulated, the hidden part emerges, delivering intense sensations. Though Madoka appears to be a gentle, big-sister type, she actually has a surprisingly girlish side. Her pussy is measured too, and the way she silently endures, holding back moans, is incredibly alluring. After the measurements, she reads aloud the naughty parts. Next, a transparent speculum is used for observation. After getting her used to it with fingers, it's inserted and slowly opened inside her vagina. The camera zooms in on her beautiful-colored pussy and inner flesh walls. When the speculum is removed, pussy juice oozes out thickly—an extremely erotic sight. Inserting and pulling out a transparent dildo, Madoka murmurs, "It's cold." When asked if she still prefers a real cock, she replies, "Yeah..." Then, they begin with a blowjob followed by sex. Madoka, who usually squirts easily, gushes fluid even from just fingering. Watching her natural big tits bounce during creampie sex looks incredibly pleasurable.
