MEYD-146 I wish I didn't know, my husband's stepson has a huge dick...

Despite opposition from those around her, AIKA married a man who was divorced and had a child. Although she appeared flashy, she was quite homely. Her relationship with her stepson was good, and the three of them lived harmoniously together. However, one day, she found herself transfixed by her stepson's erect crotch, which she had never noticed before. Seeing such a massive penis, AIKA began to view her husband's child as a member of the opposite sex... From that point on, an incestuous and twisted relationship began between AIKA and her stepson.
