Mikako-san, who lives in Tokyo, her husband has ED and is insensitive. She has no sex with her husband because their bodies don't match. Every day she is frustrated and has too much sexual desire... In the midst of all this, she meets a sex friend with a big dick. Even though she thinks it's no good, she can't stop, a dependent affair... I will deliver the whole story of the super-endowed sex between a man and a woman who are crazy for pleasure from a completely subjective point of view...
