"Of course, Mitsuki-san. It would be an honor to help."
Mitsuki turned on the sofa, giving him her back completely. Ren extended his hands and placed them gently over her tense muscles. The first contact was electric.
Mitsuki let out a soft sigh as her eyes closed immediately. Her body relaxed under Ren's touch while his fingers began to work the knots in her shoulders with circular movements.
"Mmm..." The sound escaped Mitsuki's throat without her being able to control it.
Ren swallowed hard, maintaining his concentration on the massage while simultaneously keeping the sensory manipulation he had been applying active. Every touch of his fingers felt amplified on Mitsuki's hypersensitive skin, sending small waves of pleasure traveling from her shoulders down her spine.
It's working too well, Ren thought, feeling Mitsuki's body tremble slightly under his hands.
"That feels... incredible," Mitsuki murmured, her voice sounding huskier than usual. "I didn't know I was so tense."
His fingers pressed deeper, finding another particularly stubborn knot near her neck. As he massaged it, Mitsuki arched her back involuntarily and let her head fall back.
"Ahh... right there..."
Ren noticed something strange in her posture. Mitsuki had begun to move restlessly; her legs crossed and uncrossed with increasing frequency. There was a flush rising up her neck that had nothing to do with the heat in the room.
The arousal is affecting her entire body.
Mitsuki opened her eyes briefly, glancing toward the stairs leading to the second floor.
I don't want him to come down and misunderstand this, she thought.
She closed her eyes again, letting herself be carried away by the sensations. The massage was relaxing. Every touch of Ren's fingers sent small sparks of electricity through her skin. And between her legs, a persistent tingling had begun that refused to go away.
What is happening to me? she wondered with genuine confusion. It's just a massage. Why do I feel so...
She didn't complete the thought. Because completing it would mean admitting exactly what she was feeling.
Ren continued working her shoulders; his thumbs traced firm lines along her shoulder blades. Mitsuki relaxed further into the sofa, her body melting under that expert touch. But in her relaxation, something began to happen that neither of them noticed immediately.
Mitsuki's loose green blouse had been specifically selected for comfort. The neck was wide, designed to allow free movement. And with every movement of her shoulders under the massage, the fabric began to slip. At first, it was barely perceptible. The fabric slid smoothly over her glycerin-covered skin, which acted as a natural lubricant.
Ren noticed the movement from his elevated position. His eyes focused on how the collar of the blouse had slipped enough to reveal the start of her black bra.
This... he thought, feeling his pulse accelerate.
He continued the massage, but now with a sharp awareness of how each movement caused the blouse to slide a bit more. His fingers worked the neck muscles and, when Mitsuki arched her back in response, the fabric gave another inch.
"Mmmh... that's perfect..." Mitsuki moaned softly, completely lost in the sensations.
The left strap of her blouse fell over her shoulder. Now the smooth curve of her neck and shoulder was completely exposed, her skin glowing slightly from the natural glycerin. Ren swallowed audibly. His hands trembled for a moment before he regained control.
Calm down, he ordered himself. Keep your composure.
But it was difficult to keep his composure when the valley between Mitsuki's breasts began to become visible. The blouse had fallen low enough to reveal the beginning of that tempting space, the soft curves of her breasts pressing against the black bra.
For the first time, Ren thought with growing excitement, I'm going to see her without needing to use X-rays.
His fingers kept working, but now with less focus on the actual massage and more on maintaining that gradual slide of the fabric. The second strap fell. Now both of Mitsuki's shoulders were bare; the blouse was held up solely by the barrier of her breasts. The bra was visible, the black cups contrasting against her pale skin. Ren could see the start of her nipples, the upper curve of each breast where the bra fabric ended. Just a little more and...
"Ahhh..." Mitsuki let out a louder moan this time, her hips moving involuntarily against the sofa.
The glycerin between her legs had created a wet glide that was driving her crazy. Every tiny movement felt amplified, as if she were on the brink of something she didn't want to name.
Ren's fingers pressed especially deep into a specific knot. Mitsuki arched her back violently in response, pushing her chest forward. The blouse gave way completely. It slid down to her waist in a fluid motion, revealing her upper torso covered only by the black bra.
And in that moment, just as Ren was about to see the glimpse of a nipple peeking over the edge of the cup, Mitsuki opened her eyes. She turned slightly and her gaze met Ren's directly.
Shit, panic exploded in Ren's brain. She saw exactly where I was looking. This is...
"How stupid of me!" Mitsuki suddenly exclaimed, sitting up slightly.
Ren blinked, completely confused by the reaction.
"W-what?"
"I'm asking you for a massage," Mitsuki hit her forehead with genuine frustration, "and I haven't even given you any oil! How can I expect you to do a proper job without the right tools?"
Wait... is that what she's thinking? Ren processed with incredulity. She didn't notice I was looking?
"I... it's okay, Mitsuki-san. You don't need to..."
"I insist!" She was already standing up, quickly adjusting her blouse to cover her bra. "I have some incredible massage oil upstairs. It has a cooling effect that works wonders for tense muscles. Give me just a moment."
And before Ren could protest, Mitsuki was already heading up the stairs with quick steps, her rear swaying with every step. Ren remained sitting on the sofa; his heart was beating like a war drum.
I almost saw her completely, he thought, discreetly adjusting his pants, which had become uncomfortably tight. So damn close.
He heard movement upstairs: the sound of Mitsuki rummaging through a closet. Ren took the moment to breathe deeply, trying to calm an excitement that threatened to become very obvious.
Keep control. This is an opportunity. Don't ruin it by acting like a desperate teenager.
Mitsuki's footsteps came back down the stairs. She appeared holding an elegant glass bottle filled with a clear amber liquid.
"Here it is," she said with satisfaction, sitting back down on the sofa with her back to Ren. "This oil has mint and eucalyptus extracts. It creates a cold sensation that relaxes the muscles deeply."
She passed him the bottle. Ren took it, feeling the weight of the cool glass against his palm.
"How do I apply it?"
"Just pour it into your hands and warm it up a bit by rubbing them together," Mitsuki explained as she settled in. "Then apply it directly to my skin. It's going to feel cold at first, but then it warms up."
Ren opened the bottle and the fresh scent of herbs filled the air immediately. He poured a generous amount into his palms and rubbed them together as she had instructed. The oil warmed up quickly with the friction, becoming more fluid.
"Ready," he said, positioning his hands over Mitsuki's bare shoulders.
The first contact with the oil made her inhale sharply.
"Ah! I-it's cold..."
"Too cold? Should I stop?"
"No... keep going. It feels good."
Ren began to massage again, but this time with the oil facilitating every movement. His hands slid effortlessly over Mitsuki's skin; the liquid combined with her natural glycerin to create an extremely slippery surface.
Slick... slick...
The sound was subtle but unmistakable: skin against skin with oil in between, creating that wet and slightly obscene sound.
"Mmmm..." Mitsuki let out a sigh of pure pleasure. "That is... much better..."
His hands worked her shoulders with long, fluid movements. The oil allowed for deeper penetration, and his thumbs pressed into muscles that surrendered under the treatment.
"Lower," Mitsuki murmured with a sleepy voice. "Between the shoulder blades."
Ren obeyed, sliding his hands down her back. The loose blouse had slipped again, bunching around her waist.
"Is it okay if I... move your blouse?" he asked, seeking explicit permission.
"Mmm-hmm," Mitsuki nodded, completely relaxed. "Do whatever you need."
Dangerous words, Ren thought as he gently pushed the fabric out of the way completely.
Now he had full access to her back. The black bra was the only barrier, but even that didn't matter much when his hands could work around it easily. He applied more oil, pouring a direct line over her spine. Mitsuki shivered when the cold liquid touched her hot skin.
"Ahn..."
His hands followed the path of the oil, spreading it in wide circles. Every movement was deliberate, calculated to provide maximum pleasure under the guise of muscle therapy.
"Higher," Mitsuki requested. "Near the neck."
Ren moved up, his fingers working the base of her skull where tension accumulated. Mitsuki practically melted, letting her head fall forward to give him better access.
"Oh... that's perfect..."
He worked that area for several minutes, feeling the muscles gradually loosen. But he also noticed something else: Mitsuki's breathing had become deeper. There were small pauses where she held her breath before releasing it in shaky sighs. And her hips had begun to move in small circles against the sofa, seeking a friction she couldn't explain.
"Lower?" Ren suggested. "The lower part of your back?"
"Yes... please..."
His hands descended, sliding over her spine until they reached the curve of her lower back. He applied more oil, pressing his palms firmly against the muscles on either side of the spine.
Slick... slick... slick...
The sound of the oil was more pronounced now, mixing with Mitsuki's soft pants.
"Haaa... ahh..."
Ren dared to go lower. His hands reached the top of her jeans, where the fabric met bare skin. His thumbs pressed just above the waistband.
"Mmmh... yes..."
"The thighs?" Ren asked with his voice sounding huskier than he intended.
There was a pause. A long pause where Mitsuki processed the question. Then, in a barely audible voice, she replied:
"...Yes."
Holy shit, Ren thought, feeling his arousal reach new levels. This is actually happening.
He applied more oil to his hands and placed them over Mitsuki's thighs, right where the denim tightened over her legs. The groan that came out of her was completely involuntary.
"Ahhhn..." His hands began to work, massaging the tense muscles through the denim fabric. But even through the denim, he could feel the heat radiating from her. He could feel how she trembled at every touch.
"M-higher," Mitsuki gasped. "Please..."
Ren moved his hands up, coming dangerously close to the junction of her legs. He could see how her back arched and how her hands gripped the sofa with increasing strength. And then he noticed something that made his heart stop.
Through her loose blouse, which hung loosely around her torso, he could see the contours of her breasts. And specifically, he could see two very distinct points pressing against the bra. Her nipples were completely erect. So erect that they were visible even through the padding of the bra and the fabric of the blouse. Two small peaks that betrayed exactly how aroused she was.
She's as hot as I am, Ren realized. Maybe more.
He continued massaging her thighs, his hands moving up and down in rhythmic motions. Each pass ended a little higher than the last. Every touch was a bit more intimate.
"Haaa... haaa..." Mitsuki was breathing heavily, moving her hips with more emphasis.
And then, without warning, she did something that completely surprised Ren. She lifted herself slightly from the sofa. Her hands went behind her back, searching for the clasp of her bra. There was an audible click. The bra loosened. Mitsuki pulled it out from under her blouse and tossed it aside, where it fell on the rug like a forgotten garment.
Ren swallowed so hard the sound was audible.
She took off her bra. Bakugo's mother just took off her bra in front of me. This isn't a fantasy.
"I-it was uncomfortable," Mitsuki explained with a shaky voice, without turning to look at him. "Keep going... please... the massage feels so good..."
Ren returned to her shoulders, but this time everything had changed. Without the bra as a structural barrier, he could see the full contours of her breasts from his elevated position. And when he leaned slightly forward to reach better, he glimpsed the side of her breast. The soft curve. And for a glorious moment, the rosy glimpse of her nipple.
His breath hitched. I can see her.
He worked her shoulders again, but now every movement caused her breasts to sway slightly. Her nipples brushed against the inner fabric of her blouse and, every time they did, Mitsuki inhaled sharply.
"Mmmh... ahh... yes..."
Ren moved closer, his movements becoming increasingly bold. His hands slid along her sides, brushing dangerously close to the edge of her breasts. Mitsuki didn't protest. If anything, she arched her back more, unconsciously pushing into his hands.
She wants me to touch her, Ren thought. Even if she doesn't admit it, her body is begging for it.
His heart was beating so hard he was sure she could hear it. His hands trembled slightly as he continued the massage, getting closer and closer to forbidden territory. And then Mitsuki turned. She rotated on the sofa to look at him directly. Her eyes were glassy and her pupils so dilated that barely any color remained. Her face was completely flushed, with drops of sweat mixing with the glycerin on her forehead.
And the oil. The oil had dripped from her back, sliding forward when she moved. Now there were shiny trails falling down the valley of her breasts, visible through the fabric of her soaked blouse. The sight was absolutely sinful.
"Ren," she whispered, her voice heavy with raw need, "you won't tell anyone about this?"
Ren shook his head emphatically, unable to form coherent words.
"Never," he finally managed to say. "I swear it. Never."
A smile formed on Mitsuki's face. It was aggressive, hungry, full of dangerous intent.
"Good."
And then, maintaining direct eye contact, she took the hem of her blouse and slid it down. Her breasts were exposed in all their splendor. Ren felt his brain short-circuit.
They were perfect. Firm and full, with a natural shape that defied gravity. The skin was pale and soft, shining from the glycerin covering it. And her nipples... a soft pink. Normally inverted, as he had observed with X-rays before, but now they were completely erect. They stood out proudly, hardened by arousal into sensitive points that begged for attention. The massage oil had dripped down, creating shimmering paths over her skin. Some drops had accumulated on her nipples, making them glisten under the living room light.
"Destroy them," Mitsuki whispered with barely contained lust.
Ren didn't need to be told twice. His hands moved, reaching for her breasts without hesitation. The first contact was electric. Soft, hot, and slippery. He immediately went for her nipples, pinching them between his index fingers and thumbs.
"Mmmph!" Mitsuki bit her lip hard, trapping the moan in her throat.
Ren pinched harder, rolling the erect nipples between his fingers. The texture was incredible: soft yet firm, responding to every touch by hardening further.
"Ahhhn... ngh..."
Mitsuki had to stay quiet. Katsuki was upstairs. If she moaned too loud, he would hear her. But her body wanted to scream.
Ren's hands explored, moving from her nipples toward the underside of her breasts. He gripped them fully, his palms covering them while his fingers sank into the soft flesh.
Slick... slick...
The oil made his hands slide with ease, creating that wet sound with every movement. Ren alternated techniques: first stroking gently, then squeezing firmly. His thumbs rubbed circles over her nipples while his palms massaged the rest.
"Haaa... haaa... oh God..." Mitsuki panted with her head back.
Then Ren used both index fingers simultaneously. He pressed directly onto the erect nipples, pushing them inward with firm pressure. The effect was immediate and devastating.
"MMMPH!" Mitsuki bit her lip so hard that a little blood surfaced. The pain mixed with the overwhelming pleasure made her see stars.
And between her legs, she felt the wetness. The physical evidence of her arousal had saturated her underwear and was beginning to penetrate the denim of her jeans. A dark spot appeared on the blue denim, right at the crotch. Mitsuki opened her legs slightly, unable to control herself. Her body was on fire; every nerve ending screamed for more stimulation. The blood from her lip mixed with her natural glycerin, giving her lips an even more provocative appearance.
"Ren..." she gasped, searching for his gaze. "Take off my jeans."
