The castle's secret library becomes the stage for their forbidden lust. Peach, dressed in her revealing gown, can't keep her eyes off Rosaline's tented pants. Rosaline, now confident in her new form, pushes Peach against the bookshelf, their lips meeting in a passionate, tongue-filled kiss. Peach's hands roam, feeling Rosaline's cock through her pants, then unbuttoning them to release the throbbing member. Rosaline lifts Peach's skirt, finding her bare and wet, her fingers sinking into Peach's tight, eager pussy. They fuck frantically, their moans echoing through the library, surrounded by the scent of sex and ancient parchment.
