Why do endergirls have boobs? thats stupid. Reptilians dont breastfeed so what the point?

Arly mod: Listen there anon. here is my canon to start: Endergirl grow them only as a beauty trait to seduce males, like some birds would show off their colors. ON another hand breast feeding and a reptilian aspect is compatible. Let me show you the Dimetrodon

This reptile often mistook for a dinosaur, was a mammalian creature. closer to us humans than dinosaurs.
