Old man: who the hell are these women? Where's my sweet little angels?

I'm guessing roughly a year has passed since little sister first showed up, judging by the length of her hair.

Must be something in the water, I tell you.

Damn gov putting fluoride in our water! Spoils my loli collection into having huge breasts! Terrible! Just terrible!

A grandparent will be glad at their grandkids growing up... but to these kiddos' grandparent is more amazed at how big his little angels became... in a lot of ways.

Do they take after the father's side of the family or something?

They sure are growing commonly at a specific area. What did they eat?
