The speaker returns home after several years and becomes sexually aroused by his sister's large buttocks, who is unemployed and idle. He accidentally sees her masturbating and, unable to resist, forces himself on her. While at home, he repeatedly engages in secret sexual acts when aroused, including touching her buttocks and ejaculating in the hallway. The sister protests, but the speaker forces her to orgasm. He believes she has had no sexual experience due to her reclusive lifestyle and intends to thoroughly satisfy her.










The part with the doggy style was a bit lacking, but overall the quality was pretty good. The way 'Ayahana' regained her energy from being a hopeless case was also well done, and the depiction of them falling for each other was natural. Definitely a keeper.
I was expecting this to be a work where I could fully enjoy Ayaka-san's amazing figure... but it fell short of expectations. There are plenty of shots focusing on her hips and some back views, but I was disappointed that the male actor didn't seem obsessed with them. It felt like Ayaka-san's attractive hips were just treated as a tool to get to the act, rather than being truly savored. It didn't feel like they really took the time to appreciate them.
I really like the setup of a plain girl actually being incredibly sexy, but Ayahana-san is just *too* beautiful. It didn't really feel like she was originally a plain girl, so I didn't get much enjoyment from that gap. Still, the gameplay is consistently hot and satisfying. Definitely a keeper.
Ayahana's acting was seriously captivating. The situation was fantastic, and it's just a flawless piece. Definitely a masterpiece.
Ayaka-san’s butt, which I haven’t seen in a while, is still plump and makes me want to touch it. However, this work features a lot of scenes with shorts and a peeking butt, and I couldn’t enjoy the pleasure of imagining what’s hidden. I wish there were more scenes where I could imagine the contents from the bulge appearing over tight skirts or slacks. Honestly, a bit disappointing…
