When they were both finished, each of them breathing hard, John gently extracted his hands from her body. With the lightest touch he toweled off her body, gently soaking up his cum from his mother’s back. He acted as if she were in fact sleeping, but deep down he knew the truth. When he was finished he brought the towel down to the water with him to wash it off.
As John returned he noticed that there were far fewer people on the beach. The sun was getting low over the ocean, and people had been filtering home. However, the waning light did not deter his mom from tanning. He found her stretched out on her back on the towel they had shared, legs out straight and arms along her sides, palms up. An empty bottle of water was beside her, and he realized she had used it to wet herself down. This was not uncommon, but John took note of how transparent her top and bottoms were. Her nipples poked hard through the tiny patches of cloth covering them. They were so visible that it almost looked like she was topless. Her bottoms were transparent as well, and he found he could easily see the lips of her pussy. Had his mom always worn these skimpy bikinis to the beach? She had, he realized, he had just never noticed it before.
Their eyes locked as he approached. John’s mom knew that her son desired her, while John was beginning to believe that she felt the same way towards him. They shared a brief knowing gaze until John looked away. He headed for underneath the umbrella.
“Babe?” She sounded normal, but John could not trust his own voice to sound like that. He just looked at her. “Come here, babe.” He complied, walking over to his mother, his eyes dancing briefly over her breasts and then back to her face. She was squinting against the sun, but she had seen him look at her chest. It turned her on. “Could you go fill the water for me?”
John looked past her at the empty bottle. There was a fountain just up the beach that they used for refills. “Sure mom,” he managed. He stepped around her and bent down to pick up the bottle. His ass was close to her face as he did so. When he turned around, he knew from her mischievous grin on that she had been staring at it.
When he got back his mom stood. Her bikini was still totally transparent, her body still wet. John handed her the bottle and then, suddenly, she was embracing him, her arms wrapped fully around his body. Her breasts crushed against his chest, her hips pushed right up against his. Their bodies were in full contact and John felt his erection begin. His cock grew hard against his mother, but instead of pulling away, she pushed her hips harder into him. She then kissed him on the cheek and whispered into his ear, “Thanks babe.”
His mom turned and bent down to put the water on the sand. She was far too close to him, though, and her ass pressed against his crotch. For the second time this incredible day John felt his hardening cock push against his mother’s ass. She stayed down like that longer than necessary, pretending to be setting the water in its exact place. He noticed that the crack of her ass was visible – bending had stretched her waistband down considerably When she finally stood, he could still see her ass, but she made no attempt to fix it. She was teasing him, he suddenly realized. His own mother was teasing him.
