That boobie girl might be 
doing naughty things to him.
.ربما تقوم تلك الفتاة ذات الصدر الكبير بأشياء بذيئة له
Sie und ihre Mörderhupen
vergreifen sich sicher grad an ihm …
Esa pechugona debe de estar
haciéndole cochinadas.
Esa pechugona le estará
haciendo cochinadas.
Elle lui fait peut-être
des trucs coquins.
Magari in questo momento quella tettona 
si starà approfittando di Naoya.
Aquela peituda deve estar
fazendo coisas pervertidas com ele.
Эта грудастая может его соблазнить.
