It would be an understatement to say Dean was hesitant to bring up something this taboo to Cas.
He was utterly terrified.
The idea haunted him; tormented him in his sleep but what was worse was his lack of disgust.
“You’re such a good boy, Dean. My sweet, beautiful boy.”
Dean heard those words regularly now from his angel, whether it was when he was on his knees, his jaw aching as he sucked and sucked till the angel’s eyes glowed bright, or when he was straddling the angel, rolling his hips as they came together.
But at night, deep in sleep, he started hearing those words repeated and repeated in the shadows. But not from his angel.
From his father.
And they left him wanting; waking himself up with either with an aching cock or just as an orgasm washed over him, shame mixing either arousal.
He was curious what it would be like to hear those familiar praises from the man who never gave them.
And who better to give him that than the one person he loved most.
The one who loved him the most.

Cas was immediately ready to give Dean what he wanted, with no judgement or disgust in his tone. No ulterior motive to shame or humiliate Dean.
No, he was, ultimately, very proud of Dean, for admitting something he wanted, something taboo and riddled with assumed shame.
He had Dean tell him exactly what the hunter wanted, getting Dean more and more confident with his needs and Cas illustrated what he would do, how his voice will sound, how he’ll guide Dean as they always do when they were intimate.
Dean had practically come in his pants when Cas finished going over the specifics.

They eased into it, first making out heavily, the blindfold resting along Dean’s neck, Cas fingers holding it gingerly, his grip tight and firm grounded the hunter.
Dean had initiated when Cas could change his voice when he pulled the blindfold up, his breathing shuttering as he slide off the angel’s lap.
With the nearly archangel level grace soaring through Cas, he changed his voice, the deep gruffness of John Winchester slipping through as he let out a breath.
Dean exhaled, pressing his head against Cas’s lap, his mouth parted as the angel pulled down his boxers, holding Dean’s chin and guiding him down.
The familiar taste and smell of Cas’s cock on Dean’s tongue kept the hunter grounded; the angel’s hands gripping his hair tight with welcomed control.
The first slip of praise from Cas’s mouth, dripped in his father’s tone and dialect sent a near shameful shiver of arousal through Dean.
Dean didn’t need to see as he swallowed around the angel’s cock, settling on his kneee with his ass in the air, his chest against Cas’s thighs. Cas sat in bed, his back against the headboard while Dean leaned over his lap, clad in nothing but his black boxer briefs.
“You’re such a good boy, Dean. Make me so proud.” The voice was rough, shaking slightly with arousal as Dean sucked around the head of Cas’s cock.
“That’s it, sweet boy.”
Dean’s body shivered again as the praise washed over him, the overwhelming sensation of safety and care holding him steady as he bobbed his head.
“Oh-Dean.” His father’s voice was laced with an immense amount of care and love; it was so practically out of character and with Cas’s familiar scent flooding Dean’s nose and mouth, Dean reveled in it.
He moaned against him instead, pulling up just enough to tongue around the slit, collecting the precum along his tongue before swallowing around the head once more.
Dean sucked in a breath as he felt Cas’s hand wander down his hips, sliding under his briefs. When his finger circled around Dean’s entrance, the hunter exhaled sharply through his nose, pulling off to catch his breath, his hips shaking as Cas inserted a finger inside him.
“So fucking tight, my good boy, “ His father’s voice rang rough and gutteral. Cas worked his finger in, while his other hand threaded through Dean’s hair.
Dean hummed at the touch, sliding his tongue back down Cas’s cock, dragging his lips as he kissed and sucked, moving back up just as Cas inserted a second finger. He swallowed around the head of the angel’s cock once more, his hips rocking back and forth as Cas worked his fingers, grazing his prostate sporadically.
Dean felt his nerves tighten, pleasure pooling between his legs.
Gasping, he gave one final, messy kiss to the tip of Cas’s cock before siting up slightly, pulling the blindfold down to around his neck.
“Fuck me—Cas, please—I’m close—“ Dean begged, his eyes dazed as he peered up at the angel.
Cas looked down at Dean, his eyes soft but brimming with arousal.
“You’re such a good boy, Dean. My beautiful, sweet boy.” Cas’s voice came through this time, ending the illusion.
Dean’s already flushed cheeks deepened even more so, biting his lip as leaned up to kiss Cas. He whined into the kiss, his lips twitching up into a soft grin as the angel guided his hips down, slowly lowering Dean until the hunter sat in his lap, Cas’s cock aching inside him.
Dean let out an exalted sigh, his head falling back as he rolled his hips.
They began to rock in tandem, Cas picking up the pace as he kissed along Dean’s neck, his arms wrapped around him tightly.
“So good, you feel so good Dean—“ Cas murmured, showering the hunter with praise after praise.
“Ahh—daddy!” Dean gasped his eyes scrunched closed as he came suddenly, his body jerking in the angel’s hold as his cock spilled between them.
“Oh—my Dean!” Cas gasped in surprise, coming soon after, spilling into Dean as his fell against the hunter’s chest.
The two lay against each other, breathing heavily, their bodies flushed red and hot.
“Sorry—“ Dean started, sucking in a breath. “Didn’t mean to call you…that.”
Cas shifted, cupping Dean’s cheek softly as he caught the hunter’s gaze. “I…I didn’t mind…if you…if you liked that…”
“I….” Dean bit his lip, his brow furrowed. “I don’t know honestly…” He shrugged. “Just felt right…in the moment.” He let out a breath, before kissing Cas against the lips softly.
“Thank you Cas.” Dean whispered shyly.
“I’m proud of you Dean, my sweet boy.”
“Alright you sap.” Dean bit back a grin, breathing heavily as he tucked his head against the angel’s neck, wrapping his arms around him tightly.
And Cas held him.
