Chitose, who works at an apparel shop in Tokyo, visits her parents' home during the holidays. She gets worried about her younger brother, Youta, who has been skipping school after a bad breakup. Hoping to boost his confidence, she tries to seduce him by showing off her busty figure without a bra, but she accidentally awakens his dormant, insatiable libido. Now, she's being chased and relentlessly ravaged by her super-virile brother who acts like a beast.












Chitose is a sex monster; there's no way she'd lose to some virile virgin guy. I wish the production had gone all the way and let her devour him completely.
Showing off her massive breasts to her depressed brother and saying 'sorry for teasing you'... isn't the slutty, chubby older sister actually worse than her sex-crazed, animalistic brother? (lol). In the end, she just gets ravished by her horny, adolescent brother, panting away. But look, even though Chitose Yurai is good at playing M-type characters, the direction here feels half-baked. He's a shut-in otaku brother, right? Wouldn't it have been better if she took the lead and guided him? This plot lacks a bit of punch. That said, her 'meat-cushion' physique is still there, so it was worth watching. If you can turn a blind eye to the sloppy script, you can at least enjoy Chitose Yurai's sheer lewdness. At the very least, it's a solid fap material.
It's such a turn-off when he's that aggressive; it completely kills the charm of the 'older sister' character. The best pattern is definitely when the actress takes the lead and leaves him completely dazed by the end.
