Will -
Pedaling in what passed for early morning coolness near La Manga, Will didn't have any problem with kicked up dust on the gravel road leading to the beach. Unlike the evening before, riding to check out the beaches of the regional park. The trip had not only been challenging in terms of hills and road surface, but the dust had been quite heavy at times as a stream of cars passed by. Well, stream might be an overstatement, he thought, as generally it had been 4 or 5 at a time.
When he had reached the beach around 6pm, he noticed the parking areas were still quite full, with as many cars arriving as leaving. Though he knew the Spanish followed a different rhythm, he hadn't seriously thought that so many people would be arriving in the evening. Carrying the bike down the upraised cut wood path to the flat beach, he was surprised to see though that beach was full, it was not really crowded.
The ride had been planned to simply see the park's beaches at the start of his vacation, explaining why he hadn't brought anything except water and a small towel. A number of people had told him beforehand to keep water handy in Spain, and following this dusty ride, heeding that advice paid amply rewards while rinsing his mouth. Enjoying the still cool water, he quenched his thirst under the no longer ferociously hot sun in a glorious blue sky.
He left the bike chained to a post, then walked down to the wide and white beach, his shadow starting to lengthen as the sun slowly settled. The water looked inviting, even if the sand was still too hot to comfortably walk on barefoot, as he had discovered when taking off his sandals a good 20 yards before the tide line, putting them back on hastily.
Reaching the water's edge, he took off his sandals, deciding to turn right to walk along the shore. Taking a fairly slow pace, he noticed families, topless women, often in groups, and a surprising number of preganant women, generally in fairly skimpy bikinis. Though more than a few of these women were also topless, with larger and darker aerolas making their enlarged breasts more prominent, something he found quite attractive in a surprisingly sexual way. Paying more attention to the pregnant women, especially the Spanish, if various traits provided a reliable guide in making a judgment, he found them unbelievably sexy, with a clear pride in how attractive a mother to be's body truly was. And the number of tied bikini bottoms among the pregnant women was a feast for the eye, preserving a certain modesty, while provoking speculation on the part of any man interested of just how arousing their pregnancy swelled and darkened pussy lips would look.
An interest he found himself increasingly speculating about, though Will had thought to this point his viewing had been well within the bounds of good taste. Including the couple of times he noticed a woman with her legs widely spread, sitting casually or laying down. And yes, when he noticed just how thin the covering over a woman's pussy lips was, he quickly moved his glance in another direction, though it took some effort. A real effort in the couple of cases when the fabric was actually between the women's labia, covering only the final pink moistenness between them.
Especially in light of how the women themselves seemed to be enjoying their own time in the sun. In general, the intent behind tying off bikini tops so that both strings were below the shoulder seemed to be for tanning, but it also offered a generally full side view of a woman's breasts, particularly how they hung and moved. And the number of women sunning with what seemed to be candyfloss thongs showing off their browning ass cheeks was much higher than the number to be seen standing or swimming. After some thought, a pragmatic reason became clear, as he saw a couple of women carefully position their suit bottoms before laying out in the sun, often with tops undone or discarded. A reason that also explained the number of women showing themselves off while laying stretched out on the sand, many of them clearly enjoying the chance. The reason for tied bikini bottoms with pregnant women appeared equally pragmatic, upon a bit of reflection - the bikinis still fit well, at least when the side ties were long enough to handle a certain increase in size.
As Will continued to walk, he noted a certain thinning in the middle of the second half of what was a long, somewhat divided beach - a jutting black rock formation went down virtually to the sea, with at most a couple of yards of sand separating water from rock. Walking past this narrowed stretch and gazing down what was in effect a second beach, he saw a couple of naked pairs, both later middle aged. Looking a bit more carefully at them, Will saw one pair was clearly browned deeply and evenly all over, while the other was whiter under the customary places for bathing suits.
