Miyu is a popular idol and my girlfriend's younger sister. She seems to have genuine feelings for me. But no matter how amazingly cute she is, I can't betray my girlfriend. I thought so... "Is it okay if I use you as a sex toy, as my idol?" My rationality crumbled when she took off her clothes and seduced me. By the time I realized it, we were passionately entwined, tongues locked together. The idol I know is reaching her climax with my cock... I can't escape this whirlpool of infidelity with a celebrity.
