Author's Note
Im going to try and put a reason why the MC can outlast a monster during intercourse and no im not going to make him bang every monster girl in sight because at that point I would need to put Evil MC tag, if you want to that make your own fan-fic, im also thinking of either making a new novel or continue this story after the MGQ world ends.

As Alice manages to pull off the clothes of Kayne without him noticing she wraps him up with her tail and makes him go in a laying down position, she attempts to drain Kayne of his energy but fails to do so, she sighs as the only time she drains energy is when he cums, but she barely gets a certain of it to supply her own stamina, theres an unknown energy lurking in her body but it just seeps through her like air escaping a balloon.
She can control it but for some reason she can't contain it, she knows it's harmless due to her body getting stronger from the areas this energy passed through.
But Alice shakes her thoughts off and focuses on getting more of this energy from Kayne and experiment with it later, she bends down to Kaynes lower region and gives him some light licks to get it up.
The sleeping dragon awakens and stands tall showing it's might, giving Alice slight fear at as she remembers it's capabilities, but she opens her mouth to give Kayne a blowjob, barely fitting it in her mouth and using her hands to help with pleasuring this destroyer of monsters.
Kayne slightly opens his eyes before widening them at the sight of Alice giving him a blowjob and hand at the same time he shocked but realised he was bound and tries to move, but she doesn't budge and notices he wasn't tied by her tail but bound by magic.
Realising this he just gives up knowing his unability to unseal himself from magic, and watches Alice moving her head up and down on his dick delivering him waves pleasure up his spine and feels slight pressure building at the base.
Alice turns her fingers into tentacles and wraps around his dick moving her hands up and down as well increasing the pleasure given.
Kayne feels like exploding right now but tries holding back his release but Alice goes faster, bring him closer to ejaculation.
Kayne: "I'm gonna cum!" His body trembles from the pleasure and let loose.
Alice: "Mphff *Gulp* *gulp* *gulp* ufufu you finally came" She licks off her lips of any semen that spilled, and cleans off his dick before going forward and positions her entrance above his dick.
"It's time for me to feel some pleasure too... hehe" She slams her hips down, squeezing his penis with her vaginal walls and starts moving her hips up and down.
"Ah♥ mhmm♥ ah♥" Alice moans as she attempts to outlast Kayne by being more skillful in using her walls, tightening, pulling, she makes use of everyfold and caresses the tip and shaft, sending so much pleasure Kayne is brought to the verge of cumming again.
Alice: "Your close to cumming already? that was quicker that normal... that means it's easier now then. Hora hora" She became enthusiastic thinking it will be possible to make him beg and teased him.
Kayne: "Ahg! what happened to my sensitivity?!" He tries thinking of why he became more sensitive to the pleasure but can't think and is slowly losing to his lust.
Kayne is having his sanity fade away, as the pleasure attacks his reasoning keeping the lust from exploding, but Alice keeps moving her hips with excitment as her mating instincts start getting active.
Alice: "At this point Ahn♥ I may have to Ah♥ make you marry me Haa♥"
Kayne: "Wait what no... your not" He sees her smile widely and gets a bad feeling.
Alice: "You will survive this I already know your not able to die from 3 days worth of draining" She looks at the panicking face of Kayne in satisfaction.
Kayne: 'Shit with my sensitivity now I won't be able to last that long even with my growing libido, it still has to grow'
For the whole 3 night Kayne got drained as Alice just threw a bag of coins to pay for 2 more days just to mate for the 3 days of draining.
Kayne steps out of the Inn, still wearing his mask tired and somewhat concerned as Alice managed to have sex with him for 3 days straight without him being able to reverse it, He looks at Alice who was next to him satisfied, he knows she's not pregnant due to the fact he killed his sperm by extracting the lifeforce in them making them infertile.
He swears he will pay her back for this if they ever do the marriage ceremony for monster lords.
'Wait marriage? wasn't there a request from a mermaid to help her get a ring from the kraken?' Kayne remembers about the mermaid quest and thinks it will be good to test his moves against her Aqua Pentagram and see if his Qi can pass through the so called absolute water defence technique.
Kayne travels the mermaid town to find a mermaid called Meia, and found her looking worried about something, he walked up to her and asked about her problem.
After chatting for a while, somehow convincing he's strong enough and rejecting the ball of guidence, he holds a letter in his hands while looking at the ocean.
"Well then, time to kick some giant squid ass.... maybe smash does she even have an ass? never mind im only fighting her" Kayne puts the letter he is holding into his pocket and walks forward onto the beach, but a crab girl appears.
Crab girl: "... Hey. Could you give me a little of your semen? Wait... don't you seem familiar?"
"Sorry, im in a bit of a hurry... so later!" Kayne vanishes from his spot as the crab girl remembers the masked man who vanished the same way too, then remembers she couldn't force him just now and gets fustrated and starts digging at the sand.
While in the water Kayne is slowly falling to the bottom of the ocean feeling the pressure pressing in on his body, Kayne feels it's the perfect time to reform his body to the water element, so he lowers his presence and starts drawing out the water Qi from his dantian and infuses his body with it.
A whirlpool forms around him detering any monster girl from attacking him, while his body shifts around as his skin released impurities, making an ink like cloud twirl in the whirlpool.
Alice is nearby watching him, as the whirlpool around him shrouds him in the cloud of impurities, blocking almost all sight of him and curiously stared at the process of his body as his skin is becoming more softer to the point light is reflects off it, but it rips open releasing black blood and she wonders what is happening and how did it happen.
Kayne endures the pain of the forceful regeneration of his skin being ripped as his vein and arteries are being torn apart only to be grown back to perfect condition to repeat.
Sometime later, the whirlpool spinning around him slows down and disappears dispersing the cloud of impurities carrying it away, Kayne is seen in the center of the dispersing black clouds and appears to have gotten slightly more handsome with the increased beauty of his skin nearing the point of bending the sexualality of other men.
Kayne releases a bubble of air and breathes through his pores, collecting the oxygen in the water and pulls it into his bloodstream.
He smiles knowing he can't drown and swims down to a temple and prepares as Alice watched in confusion.
Im nerfing the MC's sexual tolerance, it doesn't mean he can't still dominate it just means he takes a shorter amount of time to release.
The excuse im using? the water Qi made him more sensitive even if he hasn't reformed his body when he was having sex, he still possessed it, cleaning a mild amount of impurities covering the nerves therefore increasing his sensitivity.
