In the Russian Institute, the rules apply to everyone. Totti and David Perry even intend to remind Shalina, the director, of the rules.Faced with a fait accompli, she has no choice but to submit to the wishes of the two men. And if in fact she was only waiting for that? She decides to offer them her anus before letting them finish in double penetration. From now on, the rules will be much less strict regarding sexual relations inside the Russian Institute itself.
