【Elegant but... a bit crazy sister getting sweaty and wild every day!!】The charm of Asuka Shinonome, who plays a sister that is both talented and beautiful but with an overly unique personality, explodes in this work! Starting with her training in nothing but a fundoshi, the scenes of her big breasts swaying and dripping with sweat are eye-catching. Yuria Yoshine's 〈Ahegao〉 and outstanding acting skills shine, making this a must-see for ahegao fetishists. From the fundoshi-wearing, breast-shaking fellatio to the creampie from a mating press angle, there are plenty of highlights. Except for the training scenes, the entire film is filled with eros, and the voice acting is at the level of an audio work, receiving high praise. If there was such a sister... it's undoubtedly a masterpiece that everyone would yearn for!
