you are overestimating the things a cute daughter can do for her dad that isnt sex.
cooking for dad (and it usually tastes mediocre to bad but you suck it up and fake it like how the whore of a wife fakes her orgasms)
showering with dad
dressing up in cute clothes for dad
calling dad a dummy in a cutesy voice and a nice smile
going on picknicks
headpatting the daughter
and much much more and all you have to do is open your heart to a more wholesome image of little girls rather than a perverted one.
