[Rothen (Volke.)] A Book About Trying To Understand The Captain (Houshou Marine)

Houshou Marine gets far more hands-on research than she bargained for when an eager young fan decides the only way to truly understand his captain is up close and personal. The busty pirate quickly loses command of the situation as her small, tireless partner drives her through position after position, her breathless encouragement giving way to overwhelmed moans as she begs him to feel it even more. By the time he's buried to the hilt and thickening inside her, the captain's authority has completely melted into sweat-soaked surrender.
