Wind buffeted the portaledge, waking Tom from a restless sleep. His eyes opened to see the dim purple and gold light that meant dawn. Tom and his mother Eileen were separated by four feet of open space, below that, nothingness for two thousand feet and then a slow bank into the pine trees of Yosemite Valley. They were two-thirds up the side of El Capitan, the most spectacular wall in North America and maybe the world. Three thousand feet of pure granite, a sheer wall which from a distance looks impossible to climb. Tom and his mother Eileen were free climbers, which meant that while they use ropes for perfection in case of falls, they make their way up cliffs just with the strength of their arms and legs.
Tom stuck his head out of the flap of the suspended tent, feeling the morning air like a slap against his face. His long blond hair whipped around his head. He was 26 years old and hitting the peak of his climbing strength. Just last month he had won the North American lead climbing gold and bouldering bronze medals, and this trip was almost like a break, going back to Yosemite where his mom had taught him to climb as a child.
He considered whether to wake his Mom up, and decided it was best to get going early while the wall was cold and grippy.
"Mom!" Tom shouted, the wind carrying off most of the strength of his voice.
He waited a few seconds and called out again.
"Ya, ya, I'm up." Eileen called back. It was a few minutes until she poked her head out too.
Even though she was his mom, Tom couldn't help noticing how beautiful she was. Her bright blue eyes shone with joy and when she stepped out of her tent her toned body looked like that of a 20-year-old world champion climber, which she almost had been if not for getting pregnant with Tom at the age of 19. She had a long neck, broad shoulders and a thin waist. Her breasts were slightly smaller than average, especially in a sports bra.
Even though the pregnancy ruined her chance at a medal, she had never resented Tom. She had managed to make her own routes up El Capitan after she gave birth, one of which they were on now. They were some of the harder routes created up to this point, with some long crack climbing and a few bouldering problems which Tom often fell on. Eileen however knew the route like the back of her hand. She never slipped, knowing every foothold by heart. Tom had shifted more into competition climbing and it was always a bit of a transition to get used to natural rock surfaces again.
For the first pitch above their hanging camp, which was a long crack climb, Eileen took the lead. They both got themselves roped up to each other, and Tom prepared to belay her from the cot as Eileen climbed. Eileen reached up to the wall, her toned arms each grabbing one side of the crack, she pulled herself up and wedged her feet between the cliff walls. Hand by hand and foot by foot, she moved up the wall, linking the rope through carabiners as she moved. Tom watched as she shifted her weight, her ass dancing up the wall in front of him. Her legs were long and thin like her arms, but her ass was nice and full. He shook his head vigorously and refocused on giving enough rope for his mom to make progress. After she linked to the last carabiner, it was his turn, and he followed her same path up to the top of the crack with her ready to catch his weight with the rope if he fell.
From there they climbed a few more pitches, until they were 500 feet above their camp site. This is where they would spend the next night, but before that they had to belay down and retrieve their gear. It was always Tom's least favorite part of climbing, but it had to be done. For a route like this there was no way to do it in one day like some of the easier routes on El Capitan.
They belayed down, and began packing up the gear. They were about to start climbing again when Tom suddenly heard a yell. Turning around, he saw his mom. She had a cut across her left hand and he noticed she had no bag on her shoulder. Looking down he saw her bag, falling and bouncing off the granite wall until it disappeared.
"What happened?" Tom asked with concern in his voice.
"I slipped and cut my hand on the wall." Eileen winced, pain in her voice.
Tom considered the situation. Her bag had contained most of the cooking supplies, food, extra ropes, and her own sleeping bag and tent.
"Shit. We'll have to get to the top tomorrow." Tom said.
It was a long climb back to the point they free climbed to before, this time aided with ropes. They set up the one portaledge they still had as the sun began to set.
"We're gonna need to share a sleeping bag." Eileen said out of the blue.
"Oh..." Tom said, not knowing what else to say. He felt a slight twinge in his cock as he imagined himself wrapped around his Mom, his arms covering her perfect breasts as her ass rubbed against his cock.
"Tom." He heard, suddenly realising where he was.
"Ya mom?" He said, realising he felt a tent in his climbing pants. Judging by her reluctance to look at him, she had noticed it too.
"Let's get it set up before it gets too cold." She said, latching the tent onto the portaledge and opening the sleeping bag.
She got in fully clothed and Tom did the same. She faced away from him on her left side just as Tom had imagined. He slipped in behind Her, finding her ass jutting slightly onto his side of the sleeping bag. He shifted into place, wrapping his arms around her belly, trying to put his hands places that wouldn't be construed as sexual. He gritted his teeth trying not to let his erection strengthen and push against her ass, but it was no use.
After 10 minutes Tom cock was at full strength and jutting hard into his mom's ass. The sleeping bag was meant for one person so his crotch couldn't be pulled back at all. There was no way she didn't feel his cock. Tom laid in silence, praying she would fall asleep and his cock would too. Just her breathing was making her ass move on his cock, causing her ass to slightly shift up and down the length of his erect penis.
After another 10 minutes and no easing in his cock, Eileen suddenly spoke.
"Tom." She whispered, turning her head so gaze into his eyes. His cock twitched when they made eye contact, she didn't look angry. "I'm gonna need to sleep soon if we are going to make it to the top tomorrow. Do you think you can deal with your situation?" She spoke kindly even though she was clearly a bit frustrated.
"I'm so sorry mom!" Tom whispered back, cursing himself for being so turned on by his own mother.
"Shhh, hey, it's ok. Don't beat yourself up." Eileen said, reaching her left hand back to stroke his cheek. She had put a bandage around it and it seemed like it wasn't causing her much pain anymore. "This is harder for you than it is for me." She said, winking at him with a little smile.
Tom didn't know what to make of that. Was she not disgusted with him? His mom has always been understanding but this was not the reaction he expected from shoving his hard cock against his mom's big athletic ass.
"What should I do?" He asked aimlessly.
"What do you usually do?" She asked back.
She wanted him to masturbate?
"But there's nowhere for me to go - and it's too cold to do it outside the sleeping bag." He said, hoping she would give him permission to masturbate in the bag and not freeze his cock off sitting beside her in the tent.
"That's ok, do it here." She said softly.
