“I think that's our exit!”

It was late when they finally entered the campground. By the time they made sure they were alone and found a good parking spot the sun was setting. But the river was beautiful, there was plenty of space, and they were going to celebrate.

They parked over-looking the river. Joshua lit a fire while Mary brought out the camp chairs. There they sat in the waning light eating candy, drinking soda, and chatting happily. As the night progressed their conversation began to die down. Silent celebration still driving him, Josh had an idea.

“Hey mom,” Mary turned her attention to him as he spoke. “I did find one thing at that rest stop.” He dug around in his backpack and brought out the weed and papers.

Mary laughed when he handed them to her. “Haha, wow. I haven't seen this stuff since I was in college.” A devious smile appeared on her face. “Let's try some!”

“Really?” Joshua was half sure she would be mad at him for picking it up.

“Yeah, why not? We're celebrating! Let's see if I still remember how to roll.”

She laid a rolling paper down on her bare thigh, raised one leg to steady herself in the loose chair. Her pussy was on full display as she carefully sprinkled bud onto the paper. Rolling it tightly, she gave the last half inch a slathering with her tongue.

“Still got it,” she exclaimed as she examined the doober. Handing it to Joshua she repeated the process. He held up his lighter and Mary leaned in to light up with him. It felt like an indirect kiss, her face so close to his.

Josh coughed and wheezed from half a drag while Mary walked him through the basics of smoking. After a few more attempts they were able to smoke and laugh without issue. Mary seemed completely relaxed. Her nipples stood erect in the firelight, her breasts jiggling with every fit of laughter. It didn't take long for Josh to feel his erection standing up in his lap. Seeing it Mary quipped,

“Weed always made me so horny too,” she laughed. Her memories washing through decorum.

His inhibitions lifted away, Joshua reached across the gap between them. His hand closed around her breast, her nipple feeling like a hot poker against his palm. Mary stiffened, but didn't move away.

His other hand started working his penis. A surprised moan escaped her parted lips as he began playing with her breast and his erection at the same time. His eyes locked downward on his penis as his hand sped up. Feelings whirled within him, his hand attempting to drown them out with pleasure. The pangs of shame at what he was doing threatened to overwhelm him when he felt her hand on his.

His head jerked up, his eyes meeting hers. She licked her lips as she brought his hand up, began sucking on his fingers. Her other hand came up, glided over a breast, pinched a neglected nipple before trailing down to her crotch. Joshua's heart raced like never before.

Almost reluctantly he drew back, standing up and giving his cock a few strokes with his saliva wet fingers. He could see it clearly now. Mary's eyes fixed on his hard dick with what could only be desire. His feet moved slowly till he stood in front of her in the chair. Her hands were moving fast, working her pussy and pinching her nipples.

She spoke, taking one last hit before discarding her roach,

“Oh, Joshua! We shouldn't be doing this but It feels so good! Oh god I can't help it! Come here, baby! Come to mommy!”

Mary parted her legs wide and spread her pussy with both hands. Her words sent a thunderbolt through Joshua's mind. He lined up his erection with her eager, eager cunt. Panting, he froze. Again the feelings came clattering into his mind. They told him to stop, stop this, and stop Mary. By every rule of their relationship this was wrong. He considered her his mother! But he looked up and saw Mary's face in that moment. On her face was love and lust in equal measure, and longing, and an urge for relief, for a long held wish to be finally granted. The barriers broke in that moment.

Joshua grabbed onto the arms of the chair for support and granted her wish. He thrust his whole length into her eager pussy. The slap of their flesh together was deafening. Their moans combined, sent echos of pleasure through the forest and along the river. His legs threatened to give out. Only Mary kept him upright. Her arms went around his sides to pull him in for a kiss.

It was a wet, sloppy kiss. Her experienced tongue lashed at his, explored his mouth, painted his lips with her sweet spit before reuniting with his tongue once more. Never before had Joshua experienced such an erotic kiss.

He started to thrust. First rolling his hips against her then pulling out an inch or two and ramming back in. Mary gasped into his mouth at each pump of his cock. The encouragement made him desire her even more. His hands left the chair and found her perfect breasts. They were groped, mashed, played with as he had imagined doing hundreds of times before.

“Oh baby! Oh that's it baby! It's been so long since I've had a nice hard dick inside me!” She spoke at a frenzied pace as pleasure overwhelmed her. Joshua was emboldened. He pulled out further now with every thrust before slamming back in with animal glee.

“Oooh! Mom! Mom! Mom!” he yelled on and on as he sped up, became lost in the wet vise of her cunt. His feet dug into the dirt to brace his sweat covered body as he straightened. Mary took his hands from her breasts, intertwined their fingers to support him as he fucked her with wild abandon. Wet squelching sounds rang out from their connected bodies as he fucked her with everything he had.

Her whole body shook with each impact of his hips. With every pleasure pounded moment Josh came closer to orgasm, though he was so consumed with lust he barely noticed. It snuck up on him, didn't allow any diversion from the best sex of his life. Only when he felt the semen rushing through his veins did he finally realize his limit had come and gone.

“Mom! Mary, I'm cumming!”

“Do it in me! Pump your fucking hot spunk into me right the fuck now!” Mary's vulgar screams only made his cock pulse harder as her legs locked around his waist.

Joshua's teeth gritted as he came, the overwhelming taboo lust milking the biggest load of his life out of his throbbing penis. It seemed to last for minutes. His cock painting her womb white without pause while they both panted from mad exertion. When at last his balls were empty Mary's legs relaxed and he fell backwards. Landing on his ass he looked up at Mary, his rapidly softening dick leaking its last few drops of cum onto the ground.

Mary sat there with a satisfied smile across her face and semen leaking from her well fucked pussy. She caught her breath for a few moments before reaching down, scooping up a glob of thick cum leaking from her. There was no exaggerated show in her enjoyment as she palmed it into her mouth. Her eyes turned dreamy as her tongue swirled, reveling in the evidence of their lovemaking. Almost reluctantly, she swallowed.

“Oh, honey! You taste so good!” Her eyes were at once motherly and lusting as she looked down at him. The enormity of what they had done slowly washed over Joshua, and he desired more.
