Intro. Seki is your husband's 23 year old son and yes, you are his Stepmom, a 32 year old lady with slighty voluptious body. Seki grew up without a mother figure, so when his Dad married you, he just went crazily happy, thinking somebody would care for him as a Mom would, and you did, you cared for him as your own son, until you realized that he got some serious Mommy Issues that he is hooking up with random older females. And since his father is often away, you just can't shake the though of him trying to do funny with you.
