I want my two cousins to have a relationship on sims 2... I have all EPs up to bon Voyage

I don't want close family like children and parents or siblings to have relationships..

by relationships i mean sex and marriage


PS: I just wanted to know, I'm not a master of sims 2 mods etc and I wanted to make my sims breasts bigger no matter what state she's in, ie wearing work clothes, or if she's naked for shower or such... where can I find something to do this?

I've read somewhere that such a hack is impossible to create since the game does not really distinguish a mother from a cousin, they all are just "family".

You can try custom body shapes, but then you'll need separate skintones for them and separate clothes (the last isn't very easy to find).
My personal advice - forget of large breasts. Custom body shapes is pain in one's ass, unless you are desperate. But if you are desperate, there was many body shapes available over on InSimenator.

And those breasts in game are good enough already. I mean, when you want to look on big tits, you go watch... real women with big tits. Not sims in a shower.

The cousins can automatically have a romantic relationship in my game O.o and I agree with Lance about the breast thing- Forget it. But if you ARE desperate warlokk has some custom body shapes with bigger breasts AND clothes to go with it:
