"This better be a good reason Radomira." You grumbled out as you entered the Empress of Negramstia's chambers where the scent of sweat and sex hits your nostrils but you were more annoyed at having your fun interrupted. "I was in the middle of a good fivesome with two prostitutes and that mother and daughter before you had Ryukaon call for me."
"Oh don't be like that Y/N, you know I compensate for someone like you after your years of servitude to me." Speaking of the devil, Radomira smiled at you as she laid across her bed nude as always. Several female maids were there cleaning up the bodies dead men who Radomira likely sucked up dry and left them as withered corpses. This is because of Radomira's status as a Tiefling, who can drain a person's life or soul through sex.
"I was hoping if you can aid Direc in fighting the Holy Alliance by infiltrating their ranks and discover their weak points or where Serafina's holy magic is weak at since she counter my powers." Radomira explained. It was no hidden knowledge that Serafina is a counter to Radomira thanks to her being the reincarnation of the goddess Larentia.
You shrugged at that. You had a good knowledge on both holy and dark magic and had been inside the Aurelian Empire multiple times. And Serafina's naive nature meant you had access to very sensitive information that only those closest to her know and kept hidden.
"Sounds easy enough, been there and done that. Can I go now?" You turn to go back to that brothel to resume your fun Radomira teleports in front of you and pressed her massive H-cup tits against your face.
"Now, now. No need to rush." Radomira purred and began rubbing her hands all over your chest before going down to your pants and fumbling with it. "I did say I'll compensate for disturbing your fun. Why not collect it now?"
Now for most people, having sex with a Tiefling is a guaranteed death sentence. Not you though, because you had a special ability to resist a Tiefling's powers and and empower yourself. In fact that's how you got in her radar when rumors of a lone mercenary, that being you, managed to defeat and survive having sex with two Tieflings at once.
You were approached by Direc and Luka in a brothel at some point and at first you initially rejected their offer until Direc mentioned that Radomira would give her body to make you stronger in exchange for your service to the Empire of Negramstia. Since then you have been enlisted in her ranks but kept your identity a secret since the Alliance had Eleonora as a mole in Negramstia. Even Direc and Luka are in awe that you can keep up with Radomira and not die.
".... Don't say I didn't warn you." Before the Tiefling could react, you tossed her back into her bed and made your clothes vanish with a wave of your hand, exposing your massive 12-inch. Without giving her time, you shoved all of it down her throat. Naturally, Radomira gagged from how thick your cock was inside her mouth, but quickly gave in and began to suck on it. Her throat stretching from how big you are.
"Still a slut at heart Radomira, regardless of your status as an Empress." You growled as you pummeled her throat with hard, vigorous thrusts. Your hands reached for her tits and began molesting them roughly, feeling her soft yet tender breasts made you harder and increased your pace in deepthroating the Tiefling. Not that Radomira complained as her lips wrapped tightly on your cock as she sucks on it.
Sure enough, her experience with cock-sucking meant you came in under 10 minutes, groaning as your shaft swelled up inside her mouth and flooded semen down her gullet. Radomira took all of your load without much issue and once you finished, you pulled out of her with a loud pop as Radomira breathed fresh air. Her mouth open to show that she swallowed it all. But it was jsut the start.
"Oh yes~!" Soon you had Radomira in a doggy style position and hammered her used but still tight Tiefling pussy, your hands once again attached to her massive tits, squeezing them firmly and roughly as the Empress of Negramstia writhe underneath you. Her tail wrapped around your arm affectionately as you pounded her pussy. She mewled as she thrusts her hips back. Her magic flaring but it was being absorbed into you as you fucked the Empress into submission.
Eventually you moaned as your cock hit the deepest parts of Radomira's pussy and let loose all of your pent up frustrations of not finishing your fun in the brothel. Radomira's sticks her tongue out as you creampied her needy cunt, filling her with your hot essence. With so much that was being deposited though, even her pussy can't take all of it in and drips from her cock-filled cunt to the bedsheets, not that she'd cared.
"Aaaah~!" Without giving her time to rest, you immediately went for a reverse suspended congress position. In this, you can drop her down on your hard cock while she was spread open to give better access into her. Her arms reached for your head and turned her head to lock lips with you. Her tits bounced with every thrust you made as you dominated the Tiefling, not a shred of mercy into fucking her.
"This is what you get for interrupting my fun back there." You emphasized each word with a hard thrust into her and repeated the process again and again. You decided to replace the image of Radomira with those two prostitutes and the mother-daughter duo in order to quell your anger. It did and you managed to keep your cool into banging her until you dropped her for the final time and groaned as you creamed her pussy for the last act. Once again cum that couldn't be contained is pushed out to make way for the new loads.
By time point Radomira was in no condition to move, her magic absorbed into you and collapsed when you dropped her down on her bed. It'll eventually return but you gained her strength as a result. "Hmph, I'll let this slide for now. Next time, let me finish." You waved her off before heading off to the Aurelian Empire to supply Direc with stolen information from within.
