S1's proud genius miru and up-and-coming genius M man director are finally collaborating! One day, when her sister's boyfriend came home, she was so confident that she wasn't cool at all! When you seduce by playing with her nipples to try if it is a man who matches her sister, it is a super reaction! Whispering a dirty word in your ear, Ji Pogingin! It's a shame to ejaculate even though she is nearby! But you might want to bully me a little ... lol.
