Those Lasting Moments

Sister Edna Marie came to the St Vincent School for Girls
to give her favorite talk on sex and morality.
As she prattled on, the girls fidgeted and yawned,
glancing surreptitiously at their iphones,
wondering if the good Sister would ever bring their torments to an end.

Finally,  Sister Edna Marie said:

“Now girls, do not sacrifice a lifetime of virtue for an hour of pleasure.
Are there any questions?”

A rather pretty, shy brunette with a blond streak in her hair,
slowly raised her hand.

“Yes dear, what is your question?”

“Well, I was wondering, how do you make it last an hour?”
