A group of Russian teens, both boys and girls, huddle around their professor on the worn couch. The professor, a stern man with a thick Russian accent, begins his lesson. "Today, we learn the art of blowjob," he says, unzipping his pants. The teens, wide-eyed but eager, take turns practicing on each other and their professor. The room echoes with the sound of wet mouths and choking gagging as the teens struggle to take the cocks deep. The professor, pleased with their progress, encourages them, "Good, good. Now, swallow."
