That would be because there wasn't any. The gals were betrothed to be married when they had to flee Sodom, which can only mean they must already have been of a marriageable age; by the standards of the time, that would place them in their early teens at the youngest and it's more likely (considering that they took a while to get to their mountain dwelling and the daughters stated that they had to act soon if they wanted to have any offspring because their father was old enough that he wasn't going to be around much longer) that they were in their later teens or even twenties. Young teens were a lot more mature emotionally as well as physically in those days, since they had to grow up fast in order to survive, and everyone considered them adults back then; even in our time, fetishistic attraction to post-pubescent adolescents is known not as pedophilia (which is such an attraction to pre-pubescent children), but as hebephilia (younger adolescents) or ephebophilia (older adolescents).
In short, the parental incest is the issue at hand here. While God's laws against incest weren't in effect until Moses brought Leviticus and Deuteronomy to his people, it does remain that everybody else having children with a close relative (such as Abraham with his half-sister Sarah) was married to a peer, whereas these were unmarried gals were raping their much older father. Even before incest was outlawed, that was an awfully cruel betrayal of Lot's paternal trust and violation of their familial bonds to him.
