Reminds me of this little joke.
*clears throat*
An 8 year old girl and her mother showers together, and she notices that her mother has really big tits.
And so she asks, "when do I get tits like that?"
The mother is embarassed, and replies "I'll tell you later".
The next day, when she showers with her daddy, she marvels at his humongous cock.
She asks her daddy, "when do i get a cock like that?"
And the dad replies "you'll get it later".
