Just what had he gotten himself into?
Diluc stared down at the item strapped tightly to Rosaria's nearly-naked body. Though they had discussed it all briefly beforehand, being faced with the long, slender phallus affixed to the firm base protruding from between her thighs still sent him reeling. He'd never laid eyes on such a thing in person before, and was trying not to let his naivety regarding it get the better of him, but alas.
Rosaria quickly noticed his shocked staring.
"You're looking at it like a virgin would," She commented, the dildo bobbing with her every minute movement. "Which I happen to know for a fact you aren't."
"Give me a break," Diluc mumbled, eyes still glued to it. "It's not like I've done anything like this before."
Rosaria couldn't help the slight hint of a smile that tugged at the corners of her mouth. "Which ought to make it all the more fun." She reached down from where she stood facing Diluc, and hooked a finger on the waistband of his pants. Every other piece of his fancy, layered suit had already been tossed by the wayside during their passionate and heated foreplay.
The outline of his straining cock was embarrassingly obvious. Rosaria pulled his trousers down abruptly, releasing his stiffened manhood as it sprang out in anticipation for the night's events. Unbeknownst to it, but it wouldn't be the star of the show that night.
The pants were quickly thrown aside. Rosaria smiled deviously as she sat down on the edge of the bed, then patted her bare thigh in clear beckoning for him to come straddle her lap. Diluc felt his face burn as he sheepishly complied, swinging his leg over hers so as to seat himself atop her thighs. With his legs spread and his hard, leaking cock nudging against Rosaria's faux one, he couldn't help but feel a little out of his element.
The strange feeling toward the scenario unfolding before him was only multiplied tenfold when, as his dick nudged against hers, he noticed the clear and obvious fact that hers was bigger. It was fake, sure, but he still felt a brief pang of shame upon being shown up before he reprimanded himself for such an immature thought. This was quickly replaced by panic, as the realization that the thick, hard, rubbery and large phallus was going to go inside of him set in.
How would that even be possible?!
"I promise I'll go easy on you," Rosaria purred, her hand skirting around his waist to ghost over the curve of his bare ass.
Diluc expected a cheeky squeeze, but her hand instead kept going until it slid between the crack. He tensed up as a shiver went up his back at the graceful, slender finger prodding at his sensitive hole.
After simply teasing it, she withdrew her hand only to hastily slather it in some sort of shiny, slick liquid she had brought along with her strap-on. He recalled her reprimanding him for not keeping lube on hand himself, as she had told him it came in handy regardless of the parts involved in sexual encounters.
Her fingers returned to their scandalous position tracing the ring of tight muscle between his asscheeks, before one finger forced its way inside and began to pry him open. Diluc arched his back upon the foreign intrusion, clasping his hands onto Rosaria's shoulders for support as he nearly lost his balance on her lap.
"Gods, you're tight," Rosaria complained, wiggling her finger back and forth little by little. "It's obvious you've never done this before."
"That's why we're taking things slowly," Diluc reminded her, nearly choking on his words as she maneuvered the digit forwards and back.
"Right, slow," She agreed, before suddenly shoving in a second finger to accompany the first.
"Ah!" Diluc yelped at the stretch, a far cry from his usual gruff sighs and quiet, low-pitched moans when he and Rosaria had sex the more straightforward way. Once the slight pain from the rim of his hole being forcibly widened subsided, he attempted to acclimate himself to the sensation of two fingers rubbing up and down gently along his tight inner walls. It wasn't a bad feeling, but he wasn't getting much out of it either, until…
Rosaria crowded a third finger into his enveloping heat, shoving the digits all the way to the knuckle and hooking them forward. This forced a downright dirty whine from Diluc's throat as she brushed against his prostate.
"Wh-what was that?" Diluc gasped breathlessly, as her fingers stilled momentarily.
"I told you I'd make you feel good," Rosaria commented, repeating the motion gently. Diluc responded by jutting out his chest as he arched his back again, his expression contorting into a twisted look of confused pleasure.
Once her fingers had sufficient range of movement inside of him, she slipped them out. Diluc shuddered at the loss, but was quickly enamored with the way she used her already-slickened hand to pump her cock a few times, preparing it for its grand entrance, its dark surface now glossy with lubrication.
"Rise up on your knees," Rosaria commanded.
Diluc complied immediately, watching as she gripped the base of the cock in her hand and aimed it at his loosened hole as he hovered above it. His face blanched when he realized that she wasn't going to fuck him with the strap-on, she wanted him to fuck himself on it.
Well, he certainly wasn't turning back now.
He took a deep breath and slowly lowered himself down, the tip nudging against his hole. With each push downward encouraging it to slide inside slowly, widening his already-stretched entrance, his grip on Rosaria's shoulders only intensified. His brow furrowed with concentrated determination as he forced his hips lower and lower, taking in the long, thick phallus until his ass finally came to rest on Rosaria's thighs. He breathed a quick sigh of relief as he relaxed his muscles, though the item shoved firmly up his ass made that damn near impossible.
"How does it feel?" Rosaria had the courtesy to ask, though Diluc had a feeling she wasn't particularly interested in his answer.
"Odd."
"Really?" Rosaria shifted her weight under him, causing the dildo to nudge insistently at his insides. "That's a fairly simple adjective to choose."
"What else do you want me to say?" Diluc's grip around her shoulders tightened again, his ass clenching around the intrusion with every shift.
"If you want this to make you feel something, you have to move, you know."
"I will, I will, I just," Diluc hoisted his hips up an inch, wincing at the discomfort of the friction it induced. "Archons, how the hell—"
Rosaria watched on with mild amusement as Diluc made small, tentative attempts to fuck himself on her cock. He was flustered and his cheeks were painted pink as he gave poor little attempts at grinding down on it before hanging his head in frustrated defeat.
"Give me a minute, please," Diluc pleaded, "This is just taking some getting used to."
Diluc glanced up into her eyes, a glint of curious mischief haunting their mauve depths. He hated to bend to her so easily, but he could be quite the pushover in bed and she knew it. Still, at the very least, he finally seemed to be sliding with greater ease upon each tiny pulse up and down.
The dildo eventually slid past that tender spot that had electric bolts of pleasure coursing through him instantly. He grunted in surprised enjoyment, before gyrating his hips forward in order to strike the same spot again. It was a direct hit, the phallus pressing tantalizingly against his prostate and delivering a sudden wave of pleasure.
"Looks like you found it," Rosaria quipped, watching as he began to fuck himself in earnest in an attempt to repeatedly hit it over and over to earn himself more of that delicious euphoria.
It wasn't long until he was clumsily riding her, desperately grinding his ass against her thighs in a desperate attempt to get the dildo so deep inside it rubbed against every square inch of him. He moaned softly each time their skin slapped together, his pleasure-wracked voice breezing directly past Rosaria's ear as she wrapped her arms around him for support.
"Mmph, g-gods," Diluc groaned, his ass smacking loudly against her lap. "R-Rosaria…"
He was close now, she could tell, but she held off from trailing her fingers up his straining, leaking cock. She wanted him to come completely untouched, without the aid of a single stroke. By the looks of things, he was already at the brink.
Diluc ground his ass against her thighs, wiggling his hips desperately while burying his face in the crook of her neck. She felt a telltale streak of wetness splatter across her chest, dribbling down between her breasts in thick, viscous blobs. It was soon joined by a second smattering, then a third, each subsequently less in quantity and landing lower on her body.
"Good boy," She praised, despite knowing how annoying the man found the phrase. When he was deep in the throes of an orgasm, however, Rosaria could get away with almost anything.
"Hmph," Diluc mumbled incoherently, slumping against her body as his spent dick nudged against her messied stomach.
"Now, wasn't that good? Look, I didn't even have to touch you for you to finish." Rosaria admired the smattering of his seed sprayed carelessly across her torso, as well as dripping remnants from the tip of his flushed cock.
"Didn't think I'd come just from something up my ass," Diluc conceded tiredly, his head still lolling on her shoulder lazily. "That was unreal."
"You certainly took to it quickly," Rosaria agreed, "Seems my hunch was right."
"Hey, watch it."
"What? I'm not the one who was moaning like a whore."
She could practically feel the burning heat radiating off his face as he stiffened. He did, however, keep his mouth shut.
"Care to do this again sometime?" Rosaria hummed, her hand twining itself into his fiery red locks. "I like getting fucked in missionary as much as the next girl, but this was too much fun to not repeat if you ask me."
"Yes," Diluc admitted under his breath, suspiciously hastily. "Yes, I would."
Rosaria smirked. "Good boy."
