Nanami, an idol working in Tokyo, returns home and learns her younger brother is depressed after being teased for being a virgin. Hoping to cheer him up, she lets him touch her breasts to teach him about girls, but he suddenly snaps. Awakened by a primal urge, he forces himself on her with a fully erect member. Now, he won't leave her alone, demanding to mate all over the house.












The way her breasts bounce during cowgirl position is the best! She’s not chubby, so the contrast with her large breasts is great.
*This is Nanami Matsumoto, who is stable. It's a dream-like situation where gentle big breasts let you have sex.
There's no issue with the acting or delivery in this film, but the male actor's characterization is a huge stretch. Even for a fantasy, the acting is just too unnatural. His expressions are wooden, and there's no emotional range. His eyes are all over the place, making the character feel lifeless. I also can't shake the feeling that his look just doesn't fit the role.
The way her breasts hung down while she was on all fours was top-tier. The younger brother's groping was way too frantic and rushed from start to finish; I wish he had taken it slower so I could have enjoyed watching it more.
I love admiring Nanami Matsumoto's breasts, but overall, the angles were slightly off from what I wanted to see, which was a shame. If the angles were perfect, I'd make it my favorite work regardless of the story. Nanami has large, somewhat pendulous breasts but a high waist, so when she wears tight clothes, she can look a bit bulky, which often isn't what I'm looking for. But in this work, she wears a loose tank top, so she looked great.
