In the dimly lit study room, a stern headmistress, Stephenson Delphine, finds her young serf daydreaming. "You've been a naughty girl," she chides, pushing the student's head down to her crotch. The serf eagerly complies, unbuttoning Delphine's blouse to reveal her lacy bra. She tongues Delphine's pussy through her panties, feeling the moisture growing. Delphine orders her to strip, and the serf obeys, baring her firm tits and shaved pussy. Delphine guides the serf's mouth back to her cunt, making her lick and suck until she's dripping. Then, Delphine bends the serf over the desk, spanking her ass before thrusting her fingers into her wet cunt, fucking her hard as punishment.
