Don't cum when I'm not looking! Yuno, who lives with her boyfriend, is a very possessive girl who wants even his sperm to be hers. Yuno loves the look on a man's face when he faints! She can't get enough of having sex while watching that. She teases her boyfriend, and when he is about to ejaculate, she stops just before and does it again... She teases him and takes complete control of his ejaculation! She's a real ejaculation manager! And at the end, she makes him ejaculate inside her to confirm her love for him... I think it's okay to have love like this.
