In a forbidden encounter, the Survey Corps' elite gather for a secret, carnal lesson. The Instructor, Historia, and Ymir shed their uniforms, revealing toned, animated bodies eager for pleasure. As Historia and Ymir make out, their hands roaming each other's curves, the Instructor watches, stroking his hardening cock. He joins in, guiding Ymir's head down to Historia's waiting pussy, her tongue lapping at the eager, glistening slit. The room fills with the sound of wet, sucking noises and Historia's ecstatic moans as Ymir's tongue works its magic, her own pussy throbbing with need.
