Esci con una ragazza, pensando che la donna voglia il matrimonio, ma ti chiede solo di distruggerle il culo

You go out with a girl, thinking that the woman is for marriage and she soon asks you to destroy her ass and ends up drinking milk in her mouth. What to do in a situation like this, where you're all in love with a woman full of posture and delicious at the same time, who during conversations seemed to be all behaved and everything, but who in bed was a complete pervert who asked me to bust her ass hole without getting pity... what would you do?
