"M-Medicine in the air? Well that... explains why I feel so good I'd wager then. And s-sex slave? But I... o-oh goddess... t-that feels so good..." Evangeline began to stammer out before her words turned into moans of pleasure as she was licked and sucked on some more.
As the half-elf began to "teach" her how best to suck a person off, Evangeline's cheeks grew more and more rosy red with both arousal and embarrassment, though the latter soon began to fade to just pure lust instead. It wouldn't take a whole lot for the half-elf to coax orgasms out of Eva either, thanks to how inexperienced with sex she was. Each time the half-elf brought Eva to climax, it was such a large and voluminous event that her "teacher" wouldn't be able to drink it all down without choking, which in turn would leave Eva a bit messy from the cum spilling back onto her.
After an unknown amount of time, Eva noticed the orc guard returning, with food. At that particular moment, Eva and the half-elf were taking a break, and she was lying there recovering after yet another orgasm that left her balls aching ever so slightly, but a very pleasant ache. An ache that made her only desire yet more pleasure.
"I... y-yes please... I've been wanting to taste it ever since you left the last time..." Evangeline cooed as she helped the orc undo her trousers, her hand catching that big bulbous tipped orc cock before it simply flopped out in her face.
She remembered all of the half-elf's instructions too, and slowly began by licking from the underside of the orc's balls, all the way up to the tip of her cock, traveling along the underside of the entirety of her length. Once she reached the tip, she swirled her tongue around and around the crown of the orc's penis, teasing her relentlessly before capturing the head of that length between her lips. She sucked lightly on it a few times before releasing it, coaxing blood into the orc's length to swell her up nicely to full length.
Eva continued to tease the orc's shaft for another couple of minutes in that way, only lightly sucking on just the tip at best, while her tongue did most of the work, flicking across her cum slit, lashing all around the tip, or working from her balls all along her length. every now and then, Evangeline's lips would capture one of the orc's nice plump testes between them and she would suck a bit harder on them, though never hard enough to hurt. This continued as her left hand joined the mix and started lightly stroking the orc's cock, going just hard enough to be a constant pleasure, but never enough to bring her to climax even with the licking and light sucking.
A good minute or two after that, Evangeline smiled up at the orc and slowly inched her head forward. Slowly, but surely, Eva's lips finally, teasingly, wrapped around the orc's cock fully, after a near torturous 5 minutes or so of teasing. Once she had captured that cock, Evangeline refused to let it go, and her head started bobbing up and down its length eagerly, her tongue working it all the while from side to side. Evangeline made sure to let the orc see her cheeks puffing out from that huge orc cock lodged in her mouth too, while making eye contact with her as she peered up at the orc.
"Mmph... mmm... slurp... you taste... suck... delicious. I wouldn't mind... mmph... being your... personal cock sucker... mmm... from now on..." Evangeline moaned around the orc's cock, savoring the taste of it like the juiciest of steaks, or the finest of wines.
Evangeline gently eased her arms around the orc, holding her butt with both hands, and trying to coax her onto the bed with them. If she was able to, Evangeline would have the orc lie down, where she began to even more vigorously suck her off. Once there, Evangeline's lips wouldn't pull off the orc's dick until she had sucked her to the very edge of orgasm, where she did pull off for only a moment, so she could smile up at the orc.
"C-Cum lots for me, please, mistress... I just want to be a good sex slave for you," Evangeline cooed before wrapping her lips back around the orc's cock and bobbing up and down until she'd practically forced her to cum from her wanton desire for that orcish sperm in her mouth.
Evangeline's head didn't stop though, even as the orc came she kept sliding her lips up and down that member. She kept going even when the orc had finished cumming, already seeking to drink another load down. Her left hand would fondle the orc's balls some more, trying to coax them back into production of more semen for her to drink. Unless the orc stopped her, Evangeline wouldn't stop until she had made her cum another two times before she stopped on her own. Either way, after she had finished with the sucking, Evangeline would clean the orc's cock happily with her tongue, licking off every last drop of cum, pre, and saliva from that beautiful cock.
"P-Please mistress... I r-really need it now. Please... let my lower lips taste your cock too. P-Please... I don't even care if you put a baby in my belly. I just... know that I n-need you inside me. B-Buy this silly dragonslut sex slave if you must, j-just please fuck me..." Evangeline whimpered to the orc as she got on her hands and knees on the bed and wiggled her ass back and forth enticingly to the orc, her pussy dripping wet, a veritable flood of feminine juices.
(Looks like the ending scene will be a bit more... interesting for this route. I just started writing and it just felt so right to go this way for some reason. XD)
