In order to prove to Yuri that they are actually a married couple, Loid and Yor are supposed to kiss. Loid is willing to get this done immediately for the sake of Operation Strix, but Yor can't do this sober, so she ends up downing a bunch of wine and gets drunk.  Yuri sees his sister this way, also gets drunk, and is unable to make rational decisions anymore...
I guess you just couldn't wait to 
do naughty things with him!
أعتقد أنّك لا تستطيعين الانتظار
!حتّى تقومي بأمور بذيئة معه
zeigt mir das,
wie sehr du auf ihn stehst!
¡Eso es que te morías de ganas
de besarlo!
¡Eso es que te morías de ganas
de darte el lote con él!
Tu mourais d’envie
de l’embrasser, avoue !
Scommetto che non vedevi l'ora 
di pomiciare con lui!
Você não via a hora de
fazer indecências com ele!
Значит, тебе аж не терпелось
побаловаться с муженьком?!
