Uh-oh.  Apparently one shifting per person was not enough - Sveta could feel Yang shifting again, this time leaning against her more!  Now, Sveta was not tiny by the stretch of anyone's imagination, but Yang was...imposing, for a girl.  But things seemed to be holding up okay, the pressure from her body was a bit more than what she was used to handling, but that was no matter, right?  She could stay upright no problem, just as long as Yang didn't push over any more.  Sveta moved to position herself under Yang's arm, her shoulder finding the space in Yang's armpit to keep her up, and one of her legs sliding out to push against the armrest of the couch side she had been occupying, to brace her.
