>and even more seriously as she gets older
>was pretty good at not taking your dick, until her 20s, where she had a little monster moment and took an amount of your dick proportional to the amount she hadn't taken thus far
>and then some
>a staggering amount of your dick, to be clear
>pulls every trick in the book to hide it from her parents
>and, it... works!
>oh my god!
>takes more of your dick
>parents still clueless, this is really exciting now

>you two are always a topic at family gatherings
>"I've never met a more responsible man in my life. Mr. and Mrs. Anon, you've raised a winner. No doubt he'll be as good a husband as he is a businessman. If he waits any longer, he'll run us out of house and home on interest! Ha ha! Very shrewd, Anon! Egg on our face, to be sure!"
