The plot of this film, "Zubora Giri no Mujiku Eikyou Mi T-Back Buttocks ni Gaman Dekizu Manatsu no Boozoku Chungoshi Back Piston!", goes like this: The male protagonist gains a non-blood-related older sister, Nishimiya Yume, due to his family's remarriage!
Ah, this older sister is naturally lazy and has a proud and arrogant personality. Especially in the sweltering summer, she acts like a princess at home, always snatching the male protagonist's electric fan to cool herself off. However, dressed so casually at home, her perfectly round buttocks are always on full display for her younger brother, making the butt-obsessed male protagonist unable to resist getting an erection!
Honestly, it's really hard to stay rational when a pretty girl is walking around at home wearing only her underwear...
On this very day, Nishimiya Yume, as usual, exposed her buttocks and underwear, and even asked the male protagonist to massage her to relax. While her brother was massaging her, she kept saying things like he didn't have a girlfriend, causing the male protagonist, whose genitals had been swollen for a long time, to finally lose control and his sanity snapped!
"Even though her personality is terrible, her ass is irresistible!"
"Huh!!?? What are you doing!?"
The protagonist, having lost his mind, leaned in and licked the sweaty, beautiful buttocks repeatedly, completely perverted. Then he pulled down his underwear and... He raped his sister in his own living room and ejaculated inside her...
The protagonist's impulses weren't limited to one time. Not long after, he saw his sister trying on a bikini in her room, and he was immediately overcome by lust and rushed inside her again!
"Ugh!! Sister, my waist just won't stop!"
Doggy style, standing doggy style, side-lying doggy style—this irrational younger brother thrusts wildly from behind, even after ejaculating, he can't stop and immediately starts the next round, unable to resist the temptation of his sister's beautiful buttocks!
And Nishimiya Yume, at some point, also began to enjoy herself, not only twisting her waist vigorously but also generously performing oral sex on her younger brother…
“Let’s get this party started today!”
“Okay!”
In the end, Nishimiya Yume completely went mad.
