you need to unlock estradiol ampoule, then just give it 1 per day and dont f*ck it for 5-7 days aprox, meanwhile u are not doing s*x with her she will act weird, just dont pay attention to her and have s*X, when it pass the 5-7 days it appears a event and the next day u have a option to punish her for what she do or not, u need to do the first option and u get it
i hope my bad english wasn´t too bad to explain me x"D
