Sex

For the ordinary mortal Yuu, such exercise was an alien experience, and even with the lightest weights, he would struggle much to perform even a basic full 3 sets of ten reps.

For the immortal god dwelling within his body, it was effortless.

If you truly wished to, you could effortlessly lift an entire machine as if it were light as a feather. For appearance's sake, you settled for following Yuka's routine and (outwardly) putting much effort into every set of reps, going as far as to use your magic to give the illusion of panting and sweating heavily, taking frequent breaks in-between.

"You're doing good, Yuu-kun! Keep it up!"

Yuka would offer encouragement in the form of morale-boosting words, gentle guidance in case of wrong postures and ample skin-ship in the form of breasts pressing against his arms. Yuka often gave knowing smiles and hushed fingers to her lips, as if knowing how to manipulate Yuu's desires as a man.

You simply smirked in response, emboldened and encouraged by Yuka's actions.

Before long, after an hour of intense workout, Yuu collapsed onto the bench, (outwardly) exhausted but satisfied by his progress.

"Good work, Yuu-kun," Yuka smiled, offering a towel and a water bottle which you gratefully accepted, "You really hung in there, didn't you?"

"Well, I did have a wonderful woman encouraging me every step of the way," You winked at her, to which Yuka laughed.

"Alright, you did work hard," Yuka smiled, "And for that, you deserve a reward."

Yuka leaned in to whisper, "Wait for me in your bedroom tonight."

Your little Johnson eagerly anticipated the coming night.

That night, after a nice hot shower and a short nap from the exhaustion your body felt, stretching to get rid of the knots in your muscles, you simply lay in bed, unable to sleep, unable to calm down your little Johnson.

You hear the door open with a creak, and in snuck Yuka in her pajamas, tiptoeing to minimize the noise she made.

"Yuu-kun~! Are you awake?" Yuka whispered.

You pull her in for a kiss, catching her off-guard as your tongue wrestled with hers.

"Y-Yuu-kun?" Yuka muttered in shock.

"Did I shock you? I apologise for that," You reassure, "But I was under the impression this is my reward, is it not?"

"N-No, you're not wrong. I just didn't expect you to be so forward," Yuka composed herself with a smile.

"What can I say? I want this," You asserted.

"Then... how do you want to do it?" Asked Yuka, rubbing her legs as a certain part of her started to drip wet with arousal.

"How about you lie down and I go on top?" You suggested.

Yuka wordlessly complied, stripping herself bare and lying on her back, before slowly spreading her legs wide to expose her virgin pussy. Blushing furiously, her fingers spread her pussy lips wide open, her dripping, intact hymen bare in all its feminine glory.

Wow... seeing Yuka's body bare like this is a treat in itself.

Her boobs were a firm D-cup, her pink areolas firm as peaks and inviting him to suckle on them. Her own body, toned from years of hard exercise, were a nice blend of slender curves and firm muscle, with not a single inch of body fat visible. Her own youthful face held much resemblance to her mother Kyouka, a pointed chin and sharp nose with diamond-shaped cheeks.

You leaned in and proceeded to lick her pussy with wild abandon, tasting her salty juices and lubricating her entrance for the main course. Yuka moaned and twitched, gasping in pleasure.

"Oh my god! Keep it up, Yuu-kun! Give me more!" Yuka pleaded softly, clamping a hand on her mouth to stifle her moans.

Within minutes, Yuka was made to orgasm, squirting her juices into Yuu-kun's face and staining the sheets. In the aftermath of her climax, Yuka panted heavily, her legs feeling weak.

"That was... amazing..." Yuka muttered, "I never thought you'd make me feel so good without sex..."

"And that's just the appetizer," You smiled, "Now for the main course."

You lined up your cock with her pussy, and in one smooth motion, you hilted yourself inside Yuka's pussy, piercing through her hymen as if it was nonexistent. Yuka screamed in pain, clamping her hands firmly on her mouth to silence her voice, her eyes brimming with tears of pain. You groaned in excitement, your cock tasting womanly flesh for the first time since eons ago. Seeing Yuka's virgin blood on your cock only excited you more.

Yuka's hands tightly clutched the pillow, and you patiently hold position while she acclimatizes to the pain.

"Yuka, are you alright?" You asked with concern.

"Y-Yes, I'm fine," Yuka smiled in reassurance.

Dear god, his cock's so big! I almost felt my insides break!

Once Yuka had calmed down, you start thrusting inside of her, slowly building your rhythm to allow Yuka the full experience of pleasurable sex. As your thrusts increased in speed and ****, she began to moan with greater intensity, a challenge to her objective of maintaining silence. Her boobs jiggled like jelly, and you lean in to lick and suck on her nipples, adding yet another layer of pleasure.

"F-Fuck...! How are you so good at this, Yuu-kun?" Yuka muttered, smiling and shivering with pleasure, your balls slapping against her ass, "O-Or maybe you're a natural at this?"

Instead of answering, you smirk at her and continue fucking, your tip hitting her cervix.

And then, the time had come.

"I'm going to cum...!" You announced.

Rather than care about impregnating her, you hilt yourself balls-deep and let yourself loose, painting Yuka's womb white and inseminating her eggs. Yuka covered her mouth once again, moaning like a bitch in heat as she climaxed alongside you.

And then, you lie down on her boobs, enjoying the softness of these fleshy globes.

"You really... did well tonight, Yuu-kun."

After whispering such words, Yuka kissed your forehead, and together you drifted off to sleep.
