Thanks to my parents' remarriage, I, an only child, got a cute and weak-willed big-breasted sister! I blatantly sexually harassed my timid sister who seemed unable to resist anything. As expected, she couldn't strongly refuse, so when I forced a kiss on her, she surprisingly rejected me! But having come this far, I couldn't back down and forcibly kissed her. Then, the sister who had been resisting gradually loosened her guard and wrapped her arms around my neck of her own accord! This means we can do it! However, my sister's true nature was incredibly promiscuous, and after I came inside her, she kept demanding more, making things very difficult!
