MA-278 - Office ladies' secret double life

I bought and watched this because I was curious about the Ai Serizawa part. She has a very thin, slender build. There are no full-frontal scenes, but when she's in the missionary position, her thighs are so thin that if you grabbed them with both hands, your fingers would overlap. Her shoulders are quite small, and her wrists peeking out from her sleeves are very delicate. You can see her upper abdomen during the missionary scenes, and there's almost no muscle—her ribs are quite prominent. It's impressive that she has breasts despite being this thin. Judging by her physique, she's likely a 'starvation dieter,' so while she's very slender, she also seems to have lost all her muscle tone. I suspect she maintains that slim figure by barely eating. I can't shake the frustration of wanting to see a full-frontal scene, so I'm giving it a 3-star rating.
