Then he saw his mom coming back.
Cursing her timing, he quickly placed his hands on his stomach and tried to look innocent. He was breathing heavily and thoughts of those breasts and that ass still lingered in his head. He tried to make them go away, but found himself continuing to steal glances at her, refreshing the image. For lack of anywhere better to look, he focused on his mom, and concentrated on making his erection go down.
Fresh out of the water, she was still very much wet and her nipples were poking hard through her bikini top. Her white khaki bottoms were transparent as well, allowing a clear view of her bikini bottoms. She walked slowly towards John, her hips (and breasts) swaying as she made her way through the soft sand. The water had washed away both the evidence of her arousal and, she hoped, the dirty thoughts that had caused it. After all, this was her son, and she was not about to venture down that path.
John looked her body up and down as she approached. He was still breathing hard from his near orgasm, and his cock was still throbbing… and he found that looking at his mom didn’t help. To be honest, she was hot, and right now even the slightest sexy thing could maintain his erection. His eyes stopped at her breasts, watching them move from side to side, gazing at her erect nipples. Not only was his erection not subsiding, it was growing. Totally embarrassed, he looked down at the sand, desperately willing his erection to disappear.
His mom plopped down on the towel, out of breath from her vigorous swim, and, John thought, sitting far too close for comfort.
“Hi babe.” She smiled at him, and he returned the smile weakly. A confused look appeared on her face. “Still under here? You’re usually well into your tanning by now.”
John shrugged. “Just don’t feel like it.” His erection continued to throb in his lap. He only hoped that his bent legs hid it as he laid there on his back. Out of the corner of his eye, he noticed the girl wiggling her ass a little. Simply unable to resist, he stole a quick glance at it, and was amazed to see that her bottoms were lower still down her ass. The waistband was pulled taught against her ass cheeks, flatting them a little, but not reducing their generous curve.
John’s mom, meanwhile, was considering whether to stay in the shade or move out into the sun. She would not get a chance to come back to the beach for a while, so she would tan now. She sat up, looking to John. John returned her look and flashed a smile.
“I’m going into the sun,” she said to him. He nodded, and then his eyes widened as she began to move toward him. She got on her hands and knees and crawled towards him, reaching her hand out, towards his crotch, his enormous erection… and past it to their beach bag. Her breasts hung just above his chest, nearly touching him. God, he thought, do they look good. In his heightened sexual state, he could not help but appreciate them. His mom was almost forty, but her chest was amazing. He gazed at them longingly as she pulled a towel from their bag, and was more than a little disappointed when she pulled away. In the back of his consciousness, which was currently second to his arousal, he felt a little disgusted with himself.
