KSBJ-091 - Perfect Domination: Hotaru Mori

The story follows a son training his stuck-up stepmother while his father is away on a company trip. Hotaru Mori has a great gap between her normal expression and her 'pleasure' face, and her firm body with those voluminous breasts is very attractive. The fact that almost all the play happens in the living room makes it feel a bit repetitive, and there are very few lines that express the stepmother's internal emotional shift. It's meant to be a 'training' scenario where they just go at it, but even though she's wearing gear like handcuffs and a collar for some pretty hardcore play, her reactions and movements felt surprisingly tame.
