Slave Stepsisters 1

After the Ishiki stepsisters lose everyone except each other, they move in with eldest stepsister Yukari's fiance, Shunji Iwashiro... or at least, that's what younger stepsister Miku believes. In fact, Iwashiro has been hired to train them as perfect submissives. Shy and sweet Yukari throws herself into her training in every possible way to please Iwashiro's cock, from learning to ride him to getting both her pussy and ass filled at once, knowing she and Miku have to work as a flawless team to be allowed to stay together. But when spunky, spirited Miku finds out the truth about their situation, will she learn to submit?
