Ah, the good old days.
A friend and I were once swapping war stories, as we both have young daughters. He used to love bathing with his child when she was an infant, playing together in the tub in mountains of suds. Later, he and his wife would take turns showering with their little girl, when she was 2 or so. Then nature turned turned against their innocent father/daughter relationship. His baby girl discovered his penis while in the shower one day and gave it quick slap. From then on, he said, where ever he was in the house, it was if he penis had grown several feet. It seemed nearly impossible to keep the damned thing tucked safely away from her.
Ah children. Aren't they precious little shits?
