Two days later.
"Hehehe... Stop it, Umbra that tickles," I chuckled as the giant black cat sniffed me and my crotch. The weirdest part is I know the panther wants to do more, and it's annoying and weird how it can understand my words.
The panther, who I named Umbra, paused in his sniffing, his crimson eyes flicking up to meet mine with an almost mischievous glint. It was uncanny how well he seemed to understand me as if there was some unspoken bond between us that transcended language. I squirmed slightly, the sensation of his hot breath on my sensitive skin sending shivers down my spine.
"Seriously, you're going to make me wet," I warned, my voice coming out in a throaty purr despite my attempt to sound stern.
Umbra's tail flicked lazily, his ears perked with interest, as he resumed his exploration, his rough, textured tongue beginning to lap at my bare folds. I couldn't help but groan with pleasure, the feeling of his mouth on my slick, aching flesh was intense, and the contrasting sensations were making me light-headed.
"Ah~!"
My breath quickened, the heat pulsing through me as his tongue slid over my swollen clit, sending a shockwave of bliss through my entire body. His hot breath, and that strong, nimble tongue were almost too much for me to handle, and I could feel myself getting close to the edge.
"Fine, fine," I conceded, lying on my stomach and spreading my legs slightly to give him better access. "But don't think this means you're in charge."
My tone was playful, but there was an underlying truth to my words. Even though Umbra seemed to understand my commands, and obey my every word, I wasn't one hundred percent sure of how intelligent he was. For the past two days, we did nothing but have sex and suck each others' 'milk'.
In the two days, Umbra had cum into me more times than I could remember, and he was always ready to go when he saw that I wanted him to fuck me again, and the whole time it was fucking awesome, and I'm starting to get the hang of being a Succubus. Apparently, my milk is also an aphrodisiac to males and fills them with a high level of strength and vitality for an extended amount of time. Which makes Umbra the perfect source of food. The most satisfying food in my life.
Not only did he fuck me senseless, and every time I finish it takes everything in me to not keep sucking him dry, I've made a habit of enjoying my breakfast. Or the other way around, as Umbra gets first dibs on my tits before we start exploring each other's bodies again, and having that spiky, long cock inside me was the best feeling.
"Ahh! Fuck yes~" I moaned, the pressure of orgasm building quickly as Umbra's rough tongue traveled from my lower lips all the way to my neck.
"Damn, you're too good at this," I breathed, my voice thick with lust, as he gently bit the nape of my neck before shoving his dick right into me as if he was the one in control.
"Grrr..." the feline beast growled with a menacing low voice as the hell chains clinked around his neck. The only chain I left; was the rest I removed, allowing him to move freely.
Umbra was still not letting go, even after I promised he'd get another five or ten rounds later in the evening. His spiky cock stretched my succubus pussy deliciously as his pace picked up the momentum, turning from steady to fast and rough.
"Oh, yeah~ Just like that." I encouraged, matching his thrusts with my hips. "Fuck me just like that."
The cave filled with the sounds of our primal, carnal union, the slapping of flesh against flesh echoing off the stone walls. Umbra's ears flickered and his tail twitched with a hint of playful defiance before he intensified the tempo further, his rough, textured cock slamming into my velvety walls with the force of a beast. It was unbearably hot, the sensations intensifying and pulling me towards the edge of climax with every stroke of his deadly tool.
"More," I rasped, my mind clouded with passion. "Give me more."
The panther growled in agreement, its crimson eyes blazing with the flame of desire as we gave ourselves to each other completely, lost in the bliss of the moment. The intensity was too much, and as Umbra pounded my baby hole relentlessly, the two of us were on the brink of release.
"Come on, Umbra," I whispered, my voice hoarse. "Give it to me."
I gripped his muscular paws as he continued to ravage me with unrelenting lust. It was impossible to think of anything else, to focus on anything except the overwhelming pleasure of his rough, thick cock stuffing me over and over again, stretching my succubus insides.
"FUUUCK!"
With a final, earth-shattering roar, Umbra came. His thick, hot cum flooded my succubus pussy, filling me to the brim with his potent essence. My own orgasm followed close behind, a wave of pure, unadulterated pleasure that sent me spiraling into oblivion.
"Just like that... Ah... That's... Good boy." I managed, between gasps. My vision swam with colorful lights as waves of pleasure washed over me, wracking my body with a carnal, primal satisfaction.
My body was slick with sweat, and the familiar ache settled in as my heartbeat slowly returned to normal. Umbra had come once again and my body was covered in his white juice, my pussy sore from the rough fuck, but no matter what I love it.
"Come here," I turned, grabbing his giant head with both hands before kissing him right on the snout.
'He's actually a good kitty,' I thought smiling, as his huge tongue went around my face licking me playfully, his ears twitching, and I can tell the damn panther loved the rough fuck as much as I do.
Opening my quest interface I saw that my progress had finally reached 51% healing. Only half remained from fully healing my damaged core. However, for some reason, I noticed that after I reached 40%, my progress suddenly got slow. From 10% to 40%, it was way easier to obtain mana from the panther's essence. Drinking his cum three times and having sex three times gave me around 4 or 5% of progress, but now I only gain 1%.
'This is a big problem if I keep going like this,' I thought, rubbing my temples with a worried look, as my beautiful cat-like lover sat in front of me slowly licking my body clean.
'System, is there a reason why the rate of healing got slower by 4 or 5 times?' I asked, wondering how much time I would spend in the panther's cave before fully healing myself, and why would it decrease suddenly. I only have three days to fully heal my core or die.
Ding!
[Host, every single creature needs to have a diet and lifestyle. It's hard to survive on a single type of food no matter how nutritious. And the succubus is no different.]
'I guess that makes sense,' I nodded, it's the same reason humans eat multiple types of food every day. 'So in simple terms, I need to 'eat' from different sources, and mixing them will help me heal my core faster?'
[Exactly.]
'Fuck... do I have to go out and search for another dick?'
The question filled me with a myriad of conflicting feelings and thoughts. The memory of my encounter with the ghouls is still vivid in my mind. Would I go out and find another 'source' of food and cum to heal myself? Even though the idea of it was very tempting, the prospect of leaving Umbra and exploring this hellish realm was not as exciting.
'No, I can't risk wandering around with a damaged core,' I shook my head, trying to banish the thoughts as I looked at the screen.
'System, is there a way to increase the speed of healing without the need to search for other partners?'
Ding!
[There is a way, Host.]
'Oh shit! Really? How?!'
[You have to tame the creature known as 'Umbra' completely. Forming a contract between the two of you will boost the effect of 'Succubus's Feast' a 100% for every tamed monster.]
'Oh hell yes!' I cheered, knowing that this big, sexy feline could be more than just a sex partner. I liked him, and it would be a shame to leave this panther behind.
'So how do I form a contract between me and my hungry, love-making panther?' I asked the system, my eyes flashing with excitement.
Ding!
"Ugh!"
The moment that ding sound echoed throughout my mind I understood everything. The system just finished downloading the knowledge to me, and the fucking system didn't even warn me before starting the download process. I literally lost consciousness for 5 seconds and that's not a good thing in a situation where my life is hanging by the thin strings called quest.
'System, warn me next time,' I sent telepathically, not wanting to alert the cute, big black kitty of my condition. I'm just sitting on the ground without moving, not even a single bit.
Ignoring the stupid system, I turned to my precious lover who was still cleaning me and staring at me with a concerned expression. I was angry and surprised. This creature wasn't an idiot and seemed to know that something was wrong.
"I'm okay, boy," I said, patting his big head. "Nothing's wrong, you don't need to worry."
"Rooowww!" the panther complained, bringing his nose and sniffing me. The act was sweet and funny. I bit my lips hard enough that blood came out, before opening his mouth and letting the blood drops enter inside.
"By my blood, I, Azariel the Nephalem, request to create a blood oath with the Lesser Shadow Panther known as Umbra, for us to forever bind ourselves together."
