My younger sister came to stay in my apartment while visiting the city. It had been a while since we last met, and she looked so irresistibly cute, casually exposing her innocent charm. Wearing just her loungewear, she kept flashing glimpses of her breasts, making my heart race and desire surge uncontrollably. Being alone together again after so long, she suggested we bathe together. In the small bathroom, she innocently pressed her body against mine, causing me to become fully erect. Seeing my arousal, she excitedly took my cock into her mouth and then guided it inside her, taking it raw. Not satisfied with just one round, she begged me repeatedly for creampie after creampie in her favorite daisuki hold. What kind of ending awaits us?
