Christmas is around the corner, and a coat of snow is covering the gardens of the Russian Institute, a luxury boarding school reserved for the posh girls of high society Muscovite families. The new boarder, the young Oksana, is not the naive person that her delicious little face would let us imagine. If she has come here to perfect her instruction, it is rather a sensual and sexual high level education that she will receive. Students, supervisors, professors - and even the headmistress - all are obsessed by lust. While, secretly, the lovers of these innocent young ladies join them and make love in every positions, single girls also practise sapphic games. Thus, under the twinkling gleam of the Christmas tree in Russian Institute: Lesson 7, Oksana and her girlfriends will know the rapture of devastating orgasms.
