She let me know the next evening that her appointment was for Tuesday of the following week.

That easily fit with what I had to do, and I reassured her that I'd be able to look after the girls without any problems.

The next time Emma and Gail came over, both of them were happy for their mother, and delighted that I was coming over to spend the night with them. I let them know that I was glad to keep them company, and that seemed to be all they needed to hear before they went out back to swim for a little while. I welcomed the opportunity to stay inside where I could watch them without being noticed, entranced by their lithe figures in the bikini swimsuits their mother let them wear. Both girls had small, but noticeable, busts (Emma's was naturally a trifle larger); and both of them had firm little asses that were a treat to watch. At their age (14 and 13, at that time), they still looked a little coltish with their long, slender legs — but that was part of their beauty, to me. As they splashed around in the cool water, I caught occasional glimpses of hard nipples denting the cups of their bikini tops.

They came over again a couple of days later, and I let them talk me into joining them in the pool.

A water fight gave me the opportunity to see that their suits weren't quite as opaque when wet; the bumps of hard nipples told me were to look for nipple colors — I couldn't see a color for Emma, and Gail's looked to be a dark pink. I couldn't see any indication of the color of their pubic hair, which suggested that they either didn't have any, or it was as blond as what was on their head — both choices appealed to me equally. A little later, we got into a dunking contest, which gave me the chance to get their nubile young bodies in my hands and arms as we tried to push each other under the surface. By the time we got out of the pool, I was actually looking forward to spending the evening with them…
