If I recall correctly about the same time last year they went on a vacation and when Zoya came back she was by herself for a couple of weeks before Lev returned.
That's when she got into some heavy masturbating. She purchased a Rabbit Vibrator but only used it a couple of times the rest has always been done with her fingers or a pen.
So hoping Lev stays away for a bit and have Zoya unleash herself and let loose.
