Under the watchful eye of their elderly teacher, three Russian teen coeds practice their oral skills in a heated, hardcore session. The students, naked and eager, work their way down the professor's thick, veiny shaft, their inexperience making each stroke a new discovery. He groans, guiding them with a firm hand, as they learn to take him deep, their young throats stretching to accommodate his length. The room fills with the sound of wet, eager sucking and the occasional gag, the scent of sex heavy in the air.
