Alex rubbed his oiled hands together, warming the slick liquid until it glistened under the bedroom light.
He placed his palms on Emily's upper back, just below her shoulders, and pressed down gently at first, his fingers splaying out over her smooth, warm skin.
"Oh..." Emily sighed softly, her body tensing for a split second before melting under his touch. "That feels... nice already."
"Good," Alex murmured in a low voice. The Beginner Knowledge guided him effortlessly, he knew exactly where to apply pressure, circling his thumbs along her trapezius muscles in slow, deliberate motions.
Her skin was like silk, yielding under his hands, and he could feel the knots of tension unraveling beneath his fingertips. But his mind wandered lower, to the towel-draped curve of her ass, and he fought the urge to rush.
He worked his way down her spine, kneading the oil into her flesh with increasing firmness. Emily's breathing deepened, her body shifting slightly as he hit a particularly tight spot near her mid-back.
"Mmm, right there... that's where it hurts the most," she whispered, her voice muffled against the pillow.
Alex chuckled softly, his confidence swelling along with his cock, which strained painfully against his pants.
"Told you I'm skilled. Just relax and let me take care of you, Auntie." He leaned in closer, his breath ghosting over her neck as his hands glided lower, brushing the edge of the towel. The contact was electric, her skin flushed under his touch, and he swore he felt her shiver.
As he massaged her lower back, his fingers dipped teasingly under the towel's hem, grazing the top of her ass cheeks. Emily let out a small gasp, her hips twitching involuntarily.
"Alex... that tickles a bit," she said, but there was no protest in her tone, only a breathy curiosity that sent a jolt straight to his groin.
"Sorry," he lied, not sorry at all. He pulled back slightly, but only to pour more oil, letting it drizzle down her spine in a warm trickle that pooled at the small of her back.
His hands followed, spreading it outward in broad strokes, his thumbs pressing into the dimples above her ass. Emily moaned quietly, a soft, involuntary sound that made his pulse race. "Does that feel better?"
"Y-yes... much better," she admitted, her voice huskier now. She arched her back just a fraction, pushing her ass up toward his hands like an unspoken invitation.
The towel shifted, exposing more of her creamy skin, and Alex's restraint went off. He let his fingers wander lower, "accidentally" brushing the lace of her thong.
The massage continued like that for minutes, playful teasing disguised as professionalism.
He'd press deep into a muscle, eliciting a gasp, then lighten his touch to a feather-light caress that made her squirm.
"You're so tense here," he'd say, his voice dropping low as he worked her sides, his knuckles grazing the swell of her breasts squished against the bed. Emily's responses grew more vocal, her sighs turning to whimpers, her body responding with subtle rolls of her hips.
But then, the turning point came. As Alex's hands hovered near her thighs, Emily lifted her head slightly, her cheeks flushed a deep crimson.
"Actually... my rear aches too," she confessed in a whisper, her innocent eyes darting away in embarrassment. "From sitting at my desk all day. Could you... maybe work on that?"
Emily's heart raced as the words left her mouth, guilt flooding her like a wave.
'What am I saying? This is my stepson. I shouldn't ask him to touch me there!'
She buried her face back in the pillow, her body tense again, embarrassed by her own boldness. But the ache was real, and his hands had felt so relieving... she tried to convince herself it was just for the pain, nothing more.
Alex's breath hitched, his cock throbbing at the words. Jackpot. But he didn't dive in. Instead, he kept his voice professional.
"Of course, Auntie. That's common. I'll be gentle." He folded the towel back slowly, inch by inch, exposing her magnificent ass bit by bit. The plump cheeks quivered slightly under the cool air, the pink lace thong vanishing between them like a forbidden secret.
He started at the edges, his oiled fingers tracing the outer curves of her hips first, light and exploratory. Emily tensed, a small whimper escaping despite her efforts to stifle it.
'Oh God, this feels wrong... but so good,' she thought, her face burning with shame. She bit her lip hard, trying to hide how her body was responding, her hips shifting subtly as if to pull away but really, drawing him closer.
Alex circled wider, his palms gliding over the tops of her thighs, teasing the boundary without fully committing.
"Tell me if it's too much," he said softly, his thumbs pressing lightly into the muscle just below her cheeks, lifting them ever so slightly.
The suspense hung thick; he could see her thighs clench, her breathing quicken, but he held back, letting the anticipation build.
Emily's mind swirled with guilt. He's family... I should stop this, but the warmth spreading through her made it hard to think.
"Ahh~ Mm."
Emily suppressed a moan, turning it into a shaky breath. "It's... fine," she whispered in a strained voice, embarrassed by the dampness growing between her legs.
She tried to stay still, to pretend she wasn't enjoying it, but her body betrayed her with a subtle arch.
Finally, after what felt like an eternity of teasing strokes, Alex's hands descended fully, cupping the soft globes with a firm but controlled squeeze.
Emily gasped, her hips bucking involuntarily as he kneaded slowly, his fingers sinking into the yielding flesh.
"Ahh~ Mmm~" The moan slipped out before she could stop it, and she clamped her mouth shut, mortified. 'No, don't let him hear that...'
Alex acted oblivious. He worked methodically, pulling her cheeks apart just enough to tease, the oil making everything slick and sensitive.
Emily's attempts to hide her pleasure faltered, her breaths came in short pants as her fingers gripped the sheets.
Guilt twisted in her chest, but the building heat drowned it out. "Alex... that's... ah~" she whispered, trailing off in embarrassment, her face hidden as she fought the rising moans.
The room filled with the wet sounds of oiled skin and her stifled whimpers. Alex's control frayed; he spread her cheeks wider, massaging the inner curves, his thumbs dipping dangerously close to her cleft, brushing the lace-covered heat between her thighs, feeling the dampness seeping through.
Emily gasped as her hips buckled. "Ah! Right there... don't—" She cut herself off, ashamed of how needy she sounded.
He kept going, groping and teasing until she was a trembling mess, her ass grinding back against his hands despite her guilt.
But just as the heat peaked, and Alex thought she was going to back out. Emily turned her head with eyes filled with lust.
"Alex... can you do the front too?"
