Chapter 4: Washing Her Back
The silence between them over the next forty-eight hours was a living thing. It sat at the kitchen table during coffee, thickened the air in the narrow hallway, echoed in the too-careful ‘goodnights’ muttered through closed doors. The shameful echo of her moan in the dark seemed to vibrate in the walls. Mindy moved through her shifts at the clinic with robotic efficiency, her mind playing the same loop: the look on his face in the shower, the feverish fantasy it spawned, the subsequent crash into self-loathing. Yet, beneath the disgust, the hum remained. A low-grade, addictive current.
The flickering bulb greeted them again. The ritual was muscle memory now. The click of the lock. The folded towels on the toilet lid. The simultaneous aversion of eyes. The curtain’s shriek was the starter’s pistol.
Steam bloomed, clouding the already foggy mirror. The water hit Marcus’s shoulders, and he braced, waiting for the usual torturous hour of avoidance. He stared at a specific water stain, tracing its continent-like shape, counting the beats of his heart. The sounds of her washing were agony—the slick slide of hands over skin, the wet pull of her hair.
Then her voice, steady but softer than the water’s patter, cut through.
“Marcus.”
He flinched. “Yeah?”
“Wash my back.”
Three words. They hung in the steam, simple and impossible. His mouth went dry. The protocol, their fragile, wordless agreement, was shattered. This was a directive. An invitation into the forbidden space they’d been policing.
He didn’t trust himself to speak. He turned slowly, the water sluicing down his chest. She had her back to him, her head bowed slightly, presenting the elegant line of her spine, the taut wings of her shoulder blades. Water cascaded over the firm hemispheres of her ass, finding the shadowed divide. His breath hitched.
He took the bar of soap, fumbling it. He lathered his hands, the suds white and dense. He stepped closer. The heat of her body radiated through the centimeter of steam between them. He placed his palms flat between her shoulder blades.
Her skin was hot silk under his touch. A tremor went through her, or maybe it was him. He began to move his hands, working the lather in slow, broad circles. Down the knobs of her spine. Each vertebra a bead under his fingertips. His thumbs pressed into the muscular furrows flanking her spine, and he felt her lean back, just a fraction, into the pressure.
His cock, predictably, betrayingly, began to thicken. He tried to focus on the task, on the clinical motions of cleaning. But his hands had a will of their own. They slid lower, past the narrow waist, over the dramatic swell of her hips. His palms cupped the full, heavy curves of her ass.
She gasped, a sharp intake of steam.
His hands stilled. He was fully, painfully hard now, his erection standing out rigid and vertical, the sensitive head flaring against his lower belly. In the close, wet space, as he adjusted his stance, the swollen tip of his cock dragged a slow, inadvertent path across the slick skin of her upper thigh, then grazed the crease where her buttock met her leg.
It was an electric shock. He jerked back as if scalded.
“Shit. Mom. I’m… fuck, I’m sorry.” The words tumbled out, hot with horror. He started to turn away, shame flooding him.
“Stop.”
Her voice was low, husky. Not angry. Commanding. He froze.
“Don’t turn around.” A pause filled only by the drumming water. “It’s… it’s a natural reaction. Physiology. It’s fine.”
Physiology. The clinical word, one of her nurse’s words, hung in the air, sanitizing and obscene at the same time. It gave permission where there should be none. He didn’t move. His cock throbbed, achingly close to her skin.
“Keep washing,” she whispered.
His hands, trembling now, returned to her ass. This time, he didn’t just clean. He kneaded. His fingers dug into the firm, resilient flesh, spreading her cheeks slightly with the motion. He was openly hard, his length bobbing, and he made no further effort to hide it. The tip nudged against her, again and again, leaving a trail of sticky pre-cum on her wet skin.
She didn’t pull away. She braced her hands against the tiles, her head hanging low. He saw the muscles in her back clench. Her legs shifted, widening her stance just an inch. A silent, undeniable invitation.
He washed her with a desperate, focused intensity, his hands memorizing every contour, every slope. He soaped the powerful sweep of her lower back, the deep valley of her spine, the glorious, full rise of her ass.
They stayed like that until the water began to run cool. No more words were spoken. The only sounds were the spray, their ragged breathing, and the soft, wet sounds of his hands on her skin and his flesh against hers.
He turned off the water. The sudden silence was absolute, ringing. They stood there, dripping, in the cooling steam.
She didn’t look at him. She reached for her towel, wrapping it around herself with a swift, practiced motion that felt like the slamming of a door. She stepped out, the curtain falling behind her with a final, whispering swish.
He was left alone in the tub, his heart hammering against his ribs, his cock still painfully erect. The air was charged with what they had done and, more terrifyingly, with what they had not done. The line was not just crossed; it was obliterated, washed away with the suds down the rusty drain.
He finally reached for his own towel with numb fingers. The protocol was dead. Something else, raw and hungry, had taken its place.
