Elizaveta's eyes widen as Oliver whispers, "Today, we explore the forbidden." He guides her into the anal lesson, gently fingering her tight asshole before sliding his thick cock inside. She moans, grinding against him in doggy style, her pussy juices dripping onto the floor. Oliver's thrusts deepen, his grip tightening on her hips. He groans, pulling out and aiming his cock at her belly, showering her with hot cum. Elizaveta gasps, her body trembling with newfound desires, hungry for more advanced lessons.
