The Plan
So-young stepped into the bathroom adjoining the master bedroom and slowly began to undress. A scene rose unbidden in her mind: her legs folded in half and spread wide to the sides, her buttocks thrust out, both legs draped over her son's thighs. The view he must have had from behind.
Her strength drained away. A wave of dizziness washed over her, and she sank to the floor with a soft thud. Between her faintly trembling legs, she slipped a hand into her panties.
A wet sensation.
"Haa... haa..."
She brought her hand up before her eyes. A sticky, transparent fluid clung to her fingertips, stretching in a long, viscous string. Fresh beads of sweat formed on her forehead and cheeks, then rolled down in rivulets. A fierce thirst burned in her throat.
Bracing herself against the bathroom wall, she rose slowly. The dizziness finally began to recede. She peeled off the string camisole and dolphin shorts, then her panties and bra. Why did it feel so hard? The massage had felt good at the time, yet now her body was heavy, strange.
She stretched both arms behind her back. Even unhooking her bra took effort. At last she freed it. In the mirror facing her, her cheeks were flushed a deep red. Hyun-woo had mentioned it too. Unconsciously she brought a hand to her calf and brushed it lightly. Here... the place his thing had touched. The warmth still lingered. It had been so hard, so hot.
That was...
That was...
His cock.
Hyun-woo's cock.
"Haa...! Haa...!"
The panties reflected in the mirror bore a wet stain. That was... her pussy. Her round, full breasts, nipples jutting out between them. This was... arousal. From receiving her son's massage. She didn't want to admit it. It meant she had felt something from her own son's hands. A mother, of all people.
And yet...
Hyun-woo had been the same, hadn't he? He had looked at her legs and her ass. From behind. His erect... cock. He had prodded her calves with it. He must have known. Hyun-woo too. And she. Both of them pretending not to notice. Had he felt the same? Had he been aroused?
She shouldn't be thinking this. Yet Hyun-woo's face kept rising before her—the way he had massaged her buttocks with his forearms, sweat pouring off him, smiling so brightly. She shook her head. He was a good son. He would never harbor such filthy thoughts. It must have been the atmosphere. Or maybe the gel. Tomorrow she would ask him to do it the usual way. Yes. She had simply gotten carried away. Briefly. Both of them.
She slipped off her panties. A clear wet mark stained the crotch. She forced herself to ignore it. The shower stream poured down. She closed her eyes and let herself get soaked through, cooling her head.
Hyun-woo tossed and turned, unable to sleep. Already two in the morning. His mother's rear view kept circling through his mind. He let out a sigh. Suddenly his phone vibrated. He checked the screen. Spam? No. A message from someone. His aunt. He started in surprise. What could she want at this hour?
His aunt suddenly asking if he was awake. And at this late hour of the night. He almost never exchanged messages with her—only occasionally around the holidays.
She was a pro at shocking people. Fucking? She was saying that to her own nephew? The other party was obviously his uncle, of course. Still, it wasn't the kind of joke people usually made.
His aunt texting him late into the night. The sex jokes that kept coming. It was unsettling. He already knew she had been watching him with suspicion. He had even flirted a little, telling her her breasts and ass were pretty. But this... this felt like it was crossing a line.
Hyun-woo's heart plummeted. His aunt's messages were full of certainty. His hands trembled. He had no idea how to respond. She had helped him. Thanks to her, today he had been able to put his hands near his mother's ass and crotch, to massage her. Looking back, she was a benefactor—the one who had let him take one more step closer to his mother.
She had noticed. He had roughly guessed as much. Fortunately she wasn't an obstacle. If anything, she was helping him. She wanted a clear answer.
The conversation went quiet for a moment. He had answered honestly. That was what his aunt had wanted.
He shoved a hand into his pants and pulled out the thing that was swollen to the point of bursting. Staring at his phone, he stroked it hard and fast.
The urge to come surged up. From the reddened thing in his hand, thick white fluid shot out in powerful spurts. He ignored it and focused on the phone.
They kept the conversation going. He tapped at his phone without pause. A reliable ally. His aunt had approached him first. Said she wanted to watch. A son who was touching his mother. There was no reason to refuse. He was grateful for the help. They soon arranged for her to visit. She would fan the flames from the side, so he should do well. One condition was attached: he had to report to her by chat every day. Everything that happened, from morning to night. Even the smallest details, without leaving anything out.
Before he knew it, dazzling sunlight was forcing its way through the gaps in the blinds. He had stayed up all night. He had also learned his aunt's inclinations. She had stopped for now, but after meeting his uncle she had apparently enjoyed every kind of perverted play imaginable. There had been no further progress beyond that. Honestly he had thought she might have at least a little interest in him—she still had a pretty good body and face for someone in her forties. But he would focus on his mother.
Late evening. The living room. A woman lay face-down on the blanket spread across the floor. His mother, So-young. He had used her name when chatting with his aunt. His mother's older sister. And she hadn't gotten angry. She had gotten excited. He had messaged her just a little while ago. She would come over tomorrow to hang out. He had reported what he ate for breakfast. What he did at lunch. That he had jerked off imagining his mother. And now, the evening massage.
The same black dolphin shorts as yesterday. Frog pose. Rough breathing.
"Haa... haa..."
"Haa... haa..."
He pressed down on her buttocks with his elbows. Something hot and hard prodded at her glistening calves—jutting out through his pants. His cock. Against his mother's body. Her legs twitched. She felt it.
"Is it hard for you...?"
"No, I'm fine... I slept well, so my condition's good..."
A bright red lie. He hadn't slept a wink. All night he had imagined his mother's rear view. And the long chat with his aunt.
"When we're done... I'll do you too, Hyun-woo. I was so out of it I completely forgot..."
"Hehe... I was secretly looking forward to it."
"Really...?"
"Yeah. I've been gradually increasing my walking time... Today I walked for almost two hours..."
"Your legs must hurt a lot..."
"But my body feels good... Like I've been refreshed..."
"Haa... mmh..."
"Does it hurt a bit just from the pressing? Want me to knead instead?"
"...Do that."
He slowly raised his upper body. His mother's ass, which had filled his vision in close-up, receded. Sweat rolled down in streams from the awkward posture. He barely managed to steady himself.
"Can you... pull your body back a little?"
"Like this...?"
His mother shifted her hips slightly back toward her son. The bulging shape thrusting through his pants drew closer to her crotch. He stopped. Blood rushed hard into his lower body. Something that felt ready to punch straight through.
"I'll start... Since I'm kneading, it shouldn't hurt."
"Okay... Tell me if it gets hard... Mom will do you too..."
He gripped each of her thighs in turn. They were slick with gel, slippery and incredibly soft. He stroked upward. What he really wanted was to shove his hands inside the dolphin shorts and touch her bare ass. He would have to content himself with this much. All the effort he had put in until now could turn to foam in an instant.
He drew his hands up toward her lifted buttocks. Contact.
"Haa... haa..."
His mother's legs twitched. Her toes curled. Her son's hands had reached her ass. It was enormous. He couldn't cup it in one hand. The elasticity was incredible. Firm. Yet it also felt soft and yielding.
"You said you'd knead, Hyun-woo..."
"Yeah. The feel is just too good, I..."
"Hehe... Mom's ass is still usable, huh...?"
"When I saw it in photos it just looked pretty... But touching it, the elasticity is great... and soft."
"It's been ten years since a man touched Mom's ass."
"Really...?"
"Yeah. Even if that man is my son..."
Strength entered his hands. His mother's buttocks dimpled under her son's grip. He opened his palms, then closed them again. Repeated it.
"Mmh... haa... mmh... haa..."
Something was nodding precisely toward that spot on his mother's dolphin shorts. The shape grew distinct. The head of his cock. Intermittent moans reached his ears and sank in. Both hands traveled downward. He stroked up from her ankles, past her calves, across her thighs. They seemed to slip inward, then reached her ass again. His mother lifted her hips slightly, then settled back down. He gripped. He kneaded.
