She instinctively inclines her head to take it and stare up dazedly at her, tongue gently lapping at the intrusion as her lips start pressing around it in earnest.

"You know, one thing that I find thrilling about the Rosethorn Hotel is that there is so many opportunities to learn about all the ways that sluts like you work - and that I can tell you with absolute confidence that you have honest-to-goddess literal cock-sucking lips." 

She thrusts her finger in and out slowly, hitting against the back of her throat as she takes advantage of her soft body.

"Not just 'There's no reason make these bad at sucking cock' lips, or even 'I like sex and want it to be good' - yours have the specific optimization of being directly conceptualized as a tool to suck cock and clit above all else. So tell me, Romana, would you like to put your lips to the purpose they were made for?"

She frantically nods and slurs out around her finger "Yes please Mistress Sapphire!"

She pushes her to the floor by her head, aligning it perfectly to stare at the dripping pulsing flushing mass of fuckflesh.

She obediently stares up at the majesty of her cock, salivating and licking her lips, trembling in place with lust.

"Go ahead and kiss it, slut."

She leaned in towards it, and pressed her strained-wide lips firmly onto her foreskin, gently suckling and licking up her dribbling precum as the skin slid back against her lips in a lewd mockery of a kiss. 

She moaned throatily, and her hand stroked across Romana's head firmly and reassuringly.

"Open your mouth wide for me." 

She stares up at her once more as her mouth gapes wide, soulful eyes silently begging for it to be filled with her cock.

She swiftly grabbed two potions and poured them into her mouth with manic fevour - a potion of malleability and a "Drool-Cutie Saliva Enhancer" for safety and pleasure - then she swiftly discarded the vials and started hilting her cock inside of her.

She lets out a small contented moan as she wraps Sapphire's cock in the velvety embrace of her tight throat, slobbering and licking across her dick.

She hammered her thick cock deep inside her throat, groaning with pleasure as her heavy balls slapped against her cheek.

Cock filling her throat so full, swirling her tongue as around its length inside her, moaning and slurping at the base of her dick, fingers kneading her churning balls -

"FUCK!"

Pumping her cock in and out of her without any pretense of restraint as she skullfucked her, grinding against her face as she gets close to the edge -

Mauling her churning balls as best she can as they slap against her reddening face over and over, swallowing over and over to feel the wonderful contours of her cock as it pounds in and out of her, pussy clenching around nothing -

She shudders and fucking cums, thick seed shooting into her throat and spilling out across her cock as she moans and screams out her orgasm.

Her eyes roll back in her head as she cums in response, wetting the fabric of her kimono as she grinds her thighs and clothes against her sex as best she can while still massaging and groping and stroking around Sapphire's balls, drinking down her wonderful seed.

"Haaaa..."

Her cock soften as she slowly dragged her head off her cock, staring down at her kneeling form and swallowing dribbling lips. 

She wobbled for a moment, then pressed her face against her balls, lapping slowly and dazedly at them as she slowly caught her breath.

She let out a long contented sigh, leaning against her as she closed her eyes to focus on enjoying it.

She suckles her balls, fat lips sliding across them over and over as she strokes her hand across her ass a little clingily, before switching to firm kisses and experimental nibbles tracing across the softness of her ball sack.

Her chest rumbled with a happy groan, and stroked her cheek lightly.

She hummed quietly, and rolled her balls around in her hand, feeling there wight and heft and pinching the sack around them to feel tighter and hotter as she placed firm kisses across it and the half-hard length of her cock.

She let out a warm sigh, stroking her head absentmindedly as she kept of her attentions. 

They rested like that, for a while.

..."You realize that you don't have to keep doing this, you know?"

Her hand gently strokes her head, but this time it's a kinder caress, brushing hair away from her eyes and giving her a chance to breathe.
