It's contrasting colors here as Hinako, dressed in her black PVC dress, straps her sub into a white PVC straitjacket and then further into the Segufix. Nice and tight and unable to escape, her sub lies there alone as she attends to other matters. Upon her return, she caresses his whole body with hers. Finally, she whips out the vibrator and has her way with him. There is no escape from the vibration and nothing to stop what is to cum.
