The next day Ron awoke very late and found that Sandy was already gone. He stayed alone in the room for a while and replayed the previous night's adventures in his mind. Had he really watched Pam and Sandy fucking? He smiled to himself as he got out of bed and then had his smile melt away when he realized that it was the 4th of July and this was the last night of the trip.
It had seemed that he and Sandy's plan of getting their moms out of their usual environments had succeeded. Things had progressed much farther than Ron had ever imagined and it seemed that he and Sandy were very close to actually living out their dirty fantasy of fucking their own mothers.
Part of him was surprised how much he now wanted to fuck his mom. However, he couldn't deny that watching Pam and Sandy together had been wilder than anything he had ever seen. He was now sure that the forbidden thrill of being with his own mom while Sandy and Pam watched or even joined in would far surpass anything he had felt so far.
He quietly walked over to the door that joined his room with the one being shared by Pam and his mom. He pushed the door open softly hoping that maybe his mom and maybe even Pam would still be there. He wasn't sure what he would do or say if his mom had been there, but somehow he thought maybe the lurid events of the previous nights might drive them to try something beyond anything they would have ever imagined. Only an empty room greeted his stare, however, and he guessed that the three ladies must all be out together.
He took a long shower and thought about his own mom's actions the previous night. She had sat and watched as he fucked Pam and than as Pam sucked her daughter's pussy. What had she been thinking while she watched him fuck her close friend? Had she wondered what it would be like to be in Pam's place? The mere idea sent a shiver down his spine and made his cock tingle.
Part of him wanted to say that this was all pure fantasy on his part and that his mom would never actually agree to fuck him. Still, he couldn't deny that she had watched Pam and Sandy commit incest the previous night and, in fact, had seemed very excited by the act as she played with her own pussy and made herself cum.
As he toweled off after his shower he was startled from his daydreams by the phone ringing. It was Sandy telling him that they were out shopping and would be back in a couple of hours. He lounged on the small balcony of their room as he waited for the others to return. His anticipation of the coming night began to build and, to a certain degree, his sadness also grew that this wild trip was about to end.
True to her word Sandy and the others arrived a couple of hours later all carrying various shopping bags and laughing heartily. Part of Ron had been afraid that somehow the previous night might have made the interactions between them strained or awkward but it was clear that the women had no such problems as they talked and laughed just as normal. He quickly relaxed and listened as they filled him in on their adventures.
The ladies had all purchased new bathing suits and wanted to try them out in the hotel's large pool, so they all quickly changed and walked together down to the pool. As the other three staked out chairs Pam stopped at the poolside bar and bought a round of drinks for everyone. She returned and passed them out as they all four began to settle in to spend the rest of the afternoon relaxing and swimming together by the pool.
Ron could hardly peel his eyes off the three women with him as they each removed their robes or cover ups and revealed their new suits to him. Sandy's bikini was not that much different in the front that her previous suits except it had a little less fabric around her tits so it left much more exposed to his greedy stare. It wasn't until she turned and Ron saw that her suit was a thong did he really notice the difference. She and the others immediately noticed him staring and teased him slightly at his reaction, however Ron also noticed that both Pam and Nancy were glancing at Sandy's bare ass as she moved around her chair before settling down.
Pam and Nancy had similarly bought suits that were more revealing than anything Ron had seen them in before. Neither wore a thong or a suit as revealing as Sandy's but both were cut lower in front and higher in back than their previous suits.
The first time Sandy got up to take a dip in the pool Ron joined her for some swimming and splashing. As much as possible without looking too obvious he brushed against her and fondled her hot body under the water. They climbed out of the water together a little later.
Ron soon returned to the water when Pam made her way to the pool's edge. As he had done with her daughter he and she played closely in the water and took the opportunity to fondle or at least touch each other under the water.
That is how the rest of the day passed for them as they lounged around the pool and drank a few more rounds until they agreed they were all ready for dinner. As they made their way upstairs they talked about dinner plans and decided to perhaps just have a quiet evening rather than hitting the clubs or rowdy bars. They all changed and made the short walk to the restaurant next to the hotel for a leisurely meal. Several more rounds of drinks were consumed by all during the meal and by the time they were ready to leave the restaurant they were all feeling tipsy.
"I know we talked about staying in," Sandy said, "but is anyone up for one last night on the town?" Ron knew right away what Sandy was trying to do. She hoped that the alcohol combined with the acts of the previous night and the sexy environment in the dance clubs might be the spark that would bring their plan to completion.
"I don't think I'm up for that," Nancy answered, "I was kind of looking forward to spending the night with just the four of us." Ron couldn't quite put his finger on it, but there had definitely been something mischievous and a little sexy about his mom's tone that made him excited. Sandy perhaps picked up on the same thing as they all agreed and began walking back to the hotel.
Once up in the room again Pam rummaged through one of her bags and produced a bottle of alcohol she had purchased that day apparently in anticipation of the night to come. They each poured a glass and went out to the small balcony. The parties for the holiday were already in full swing and with increasing regularity fireworks would shoot into the air. They talked and looked out over the partying below.
They sat talking and drinking for a while longer listening to the music coming from the radio that Sandy had turned on earlier. They moved inside the room a short while later when the lights on their balcony began attracting bugs. As they walked into the room the radio began playing a particularly upbeat number. Sandy laughed and excitedly said, "Oooo, I love this song!"
