Breeding for good traits.

[tcampos850]

In my play throughs I usually intermarry family to breed positive traits like pure blood, comely and robust. But I’ve been finding it very difficult to breed breast traits like budding and voluptuous. What’s the best way to breed large breast traits. Or large penis traits as well. I unlock the blood dynasty perks but after my third generation I haven’t been able to get a female with large breast traits.
