This Masha won't let any dick past her. Cyclist Stepa just stopped to sit and rest. And that bitch came on to him. How can you resist? That's how guys are - you let your chick go out for an hour, and look, someone's already screwing her in the asshole. And then she acts like a prude - her mother won't let her, only after the wedding! You've got to pull them off the first night!
The housekeeper showed a lot of chutzpah and assertiveness. So it would be strange if the master let it all slide. So he wasn't rude to her either, and he indulged himself in various poses, mostly crawling.
