The recent work of Ichino Aoi that I watched, 'Substituted Fleshlight Series', is shocking in content but extremely erotic. Her excellent acting is well-highlighted by Oki, and the developments from the second half to the ending were particularly impressive. Some fans seem to enjoy the reluctant situations, especially getting excited about the scene with the collar. However, the low energy of the actor playing the boss was a bit off-putting at times, which was disappointing. Overall, this is one of the top works in Ichino Aoi's repertoire, and the first viewing being free adds to its appeal. This series rarely disappoints and is a must-see for fans!
