The in-laws have a dog named Tinkerbell
my angelic and pure Mother-in-law favors indelicate terms for the female body part.
(Hint: when I tell the above Mother-in-law stories at work I have to say "Twah" instead so no one can report me to HR.)
Gary told me that he visited his Mom today. They spent some time on the floor with Tinkerbell, rubbing the dog's belly. Gary mentioned how it was easier to rub a girl dog's belly, because they don't have a penis to dodge.
Wilma said, "Well, she's a girl, so she doesn't have a penis."
"Stop right there," I interrupted, "Your mother did not say 'penis.'"
"Oh, well, neither did I," he confessed. "I said 'thingee' or 'willy,' and so did she. But wait."
Wilma said, "She's a girl. See, she has vaginal folds."
"You lie! I know you lie. Your mother never said 'vaginal folds.'"
"She did! She said it very precisely. I think she remembers the last time she said ... the other thing."
So then, Gary's Mom began rubbing Tinkerbell's vaginal folds.
He said to his mother, "Really, Mom, you may not want to do that."
"No, she likes it."
So, I say it's a net gain. Sure, she's masturbating the dog, but she's dropped the Twah word.
