those are bit pain, tho is easier in new house i guess, since you can visit her at any time.
before that had 2 options
party - get her drunk, say you got condom and not use it
and mid day coffee visit tho that one is tricky, you can whether rely on 48h active sperm and have sex with her 1 day before her ovul (during her ovul and week after she will force you to wear condom), or like i do, set ovul on next day and when you are pass the condom option - set it back on current, worked every time.
1st kid might be scripted tho, like pretty much all are. and if thats the case check the guides poped in ops, mini guide is updated.
i remember back in day (now pregnancy is easy), Paola was pain, you had 5% chance on ovul day, then got increased on 10%,... up to now when you can knock them up out of ovul period. i had to do 14 ovul days for one of her kids, lucky was cheesing and rolling ovul day, many didnt i feelt sorry for them
, still was quite a gind to get them prego, some worst than others.
