She bounced against him, letting out higher-pitched gasps, holding on, letting go, letting her breath rise out like a dragon, growling, rolling, and groaning as she was being pumped and pressed against!
Such sounds are coming from them now–sounds that traveled out from the alleyway.
“Ahh… And you… worried… I couldn't… do this…!” Rei snarked between pants; holding the little woman up in his arms, even with the pub’s exterior as additional support, proved it would be a physical workout for himself…! “Sing…!”
Tik Tik wailed in delight as he filled her, using her as his sleeve, and she glanced off to the side, smirking deviously as she moaned out louder and more boisterous than ever!
He buried his face in her neck, lips claiming that taut and scaly flesh, while his dressed legs were on full display, like nylon-coated pillars supporting their foundation of fornication. His slender digits worked her body more and more, forcing her to take his cock as deep as she could go, with the lewd sounds of clapping emanating from their genitalia!
“C… come on…fuck your teacher…!” she growled, speaking so dirty in her eloquent speech, her legs spread, her stomach bulging from her human’s manhood, “you want to use me… ha… like your… magical… cumdump, h-huh? Talk dirty, nngh… tell me what you… ha… think of… meee!”
“Tight… warm… clingy…! Made for… large dicks…!!” Rei was shuddering against the ever-building reserves between his legs as his smaller lover was ravishing his ears with that audial temptation, that serpentine encouragement, her superior words taunting HIM now…! “K-Kobold like you… smart, incredible–still, kobold like you–only made… for big cocks… to destroy…~!!” Every penetrating thrust was now accentuated with a juicy ball-clap against the base of her tail…!!
Her eyes rolled back, her body bouncing with each thrust, her mouth hanging open when she wasn’t adding more and more of her dirty talk. And he wouldn’t have much opportunity to say much more himself before the walls around his length constricted and spasmed in the tell-tale signs of koboldy orgasm, milking him like a vibrating toy at the pinnacle of his own arousal!
He threw his head back from the intensity of her climax before pinning her firmly against the outside of the establishment, cock aching before finally unloading shot after shot of his creamy torrent inside the little woman! The eromancer would find the hot surge rushing into a delectable dead end–nowhere to go but inside her tight, enchanted womb!
“Ah… Fasc’natin…! Miss Tik… You’re… a little succubus…!!”
“And yet…” she huffed, her tail dangling down, her arms clinging to his shoulders for all the support she could get, before nuzzling against him, “you’ve fallen for me, my student.” 
“Way Miss Tik speak, way Miss Tik act… Hard not to…”
“Ready to head back?” She posited.
He shook his head, granting the little woman a peck on her forehead. “Rei said… this only start… Nice, lovely park… More green than rest of town, good place to rest under tree, lovely to look…” Another kiss. “...And more open than alley…~”
She growled at that, hissing gently, squirming around in his grasp while she eased herself off of her pupil’s member. With a snap of her fingers, the two of them were clean. The sweat and marks of their rutting lost all of their exterior evidence. 
“Oooh, if we’re going to raise the stakes, let’s raise them, shall we?” She snickered. “It’s not a matter of if we get caught… but how long we last undiscovered~ And what you’ll do once we are. You shall be graded in both regards.”
“Then Rei make sure no disappoint you, Miss Tik!” The sorcerer beamed, readjusting his attire; an additional follow-through alongside her eromancy–not having the clothes firmly secured would make the cleaning effects moot. His fingers traced along the back of her head before offering his hand to her. “Now, shall we?” He provided with a playful grin. “Or would you like me to scoop you up and hold you like a little bride~?”
“Hmph, thinking you can take a break from Draconic today, my student?” the kobold chided, eyes narrowing, before she chuckled and took his hand. Except for a little soft panting, she seemed quite natural. And not having her afternoon rocked? “Okay! Take a half-hour break from Draconic-speak. Rei is getting better, but nowhere near speaking as well as Tik still.”
“Rushing won’t do either of us any good, Miss Tik. I know you’ll keep reminding me of THAT rule~”
If some eyes had glanced down the alley at the sight of a human breeding a kobold, there wouldn’t be any point hiding it now. The sorcerer’s digits were incensed with warmth before he leaned in and scooped the little woman into a bridal carry. Of course, this was the reminder that perhaps Rei should invest some time in maintaining some sort of physical strength in his life, but the strain was worth it.
But who cared about what anyone would think if they saw a young man carrying a melon-pink kobold in his arms? The day was still young, and a bright, verdant park in the center of this stuffy city could stand to be… ‘devalued’ a little.
