HUNTA-162 I'm an only c**, but I now have a cute, timid, big-breasted sister! She gives off an air of being open, so it's blatant sexual harassment! I can't refuse her, as I thought. This is going to work! This is definitely going to work! But when I tried to kiss her, she refused. I pushed aside her guard and didn't give up, so I f** a kiss on her...

Thanks to my parents' remarriage, I, an only c**, now have a timid, cute, big-breasted sister! I blatantly sexually harass my timid sister, who seems unable to resist anything I do! As expected, she can't say no, so when I try to kiss her, she unexpectedly refuses! But I can't turn back now, so I forcefully kiss her! Then, my sister's guard, which had been reluctant, gradually lets down, and she puts her arms around my neck of her own accord! Now I can do it! However, my sister's true nature is incredibly lewd, and after I came inside her, she kept asking for it over and over again, which was a pain!
