My stepmother is totally my type!

Shinichi's father remarried and a new mother came to live with him. Having been raised by his father alone, Shinichi expected a middle-aged, overweight woman to show up, but instead, he was greeted by an incredibly beautiful woman with large breasts. His new stepmother, Alice, was very affectionate, walking around in revealing clothing after her bath, which caused Shinichi to have wet dreams.
