The "Mom is sleeping in the next room and I'm sitting" part does trigger the Russian association but also others including with risqué roleplay content (You can see this in the comprehensive view of all token explanations). I think the follow-on content does strenghten the association, though the authors mention 'vodka' can be replaced with 'champagne' and the model still brings up the Russian context, so that one word is not especially impactful.
