Yuka peppering you with kisses

It was late at night and you returned home late at 9pm after ending your part-time shift. Izakaya Akita was a little far, but crucial to your plans. Captain Shioko was just the beginning, and you needed to further gain her trust before you could start worming your way into her mind with your magic.

The moment you opened the door, however, you are greeted by Yuka pulling you into a bear hug and peppering your forehead with kisses all over.

"Whoa, what's gotten into you, Yuka-neechan?" You asked smilingly.

"What, can't a dear sister shower you with love after a hard day of work?" Yuka teased, clinging tightly onto your arm and making sure it was pressing against her bosom.

You saw her give you a sly wink, and you rolled your eyes.

"It's only my first day of work, you know," You remarked.

"Still the same thing," Yuka pouted slightly.

"You just want an excuse to have sex with me, don't you?" You inquired.

Yuka merely smiled, and you knew it was a yes.

You let her pull you into the toilet where you welcome a hot shower to loosen the knots in your body. Yuka takes the time to thoroughly scrub every part of your body, her hands freely fondling your manhood and caressing it until it was rock-hard.

You respond by massaging and kneading her ample bosom and shapely rear, toned from years of squats and bench presses with heavy weights. Her abs were firm to the touch, her body a healthy mixture of slim, curvy, thicc and muscular. Once again, you marvel at the sheer luck Yuu had with getting such beauteous girlfriends and question the author's sanity at ruining it.

Yuka kissed you on the lips, poking her tongue into your mouth.

"Did I ever tell you how many men I've had fawning over me at work and among my friends?" Yuka asked.

"You told me there were countless," You answered.

"Yes, and none of them were my type," Yuka said, looking slightly irritated, "Honestly speaking, they just take look at my face and body and decide they're in love, as if I'm some kind of trophy wife. They're not as kind, understanding and helpful as you are, Yuu-kun. And they certainly don't know how to treat a woman properly."

"I can only imagine," You said.

"Even so, I can't help but feel that you've... changed somehow," Yuka mentioned, which caught your attention, "You seem a lot more manly, confident, as if you know what to do next in life."

"Well, you could say after reaching a certain age and having to start thinking for my future, I felt that it's better to not be so reliant on others for help," You answered, knowing that the original Yuu would say the same, "Don't get me wrong, I'm grateful to you all for taking me in, it's just that it wouldn't be right to mooch off your goodwill."

Yuka sighed but smiled, patting your head, "Look at you, maturing into a grown man already."

"Well, everyone has to grow up sometimes," You shrug.

Yuka kissed you on the lips again, and inspiration strikes you that moment; channeling a little magic, you make your saliva enhance her erogenous sensitivity, making her body more susceptible to lust. She shivers as her face flushes red, and you tweak her nipples just a slight bit, making her gasp and moan with a high-pitched voice.

"Y-Yuu-kun, you're making me really excited," Yuka muttered breathily, hearts shining in her eyes.

"Then how about we fuck each other like animals in the bedroom?" You suggest.

There is only one answer Yuka gives, and that is in the form of a full-blown adult kiss, your tongues clashing in a fierce awakening of inhibited sexual lust.

That night, you ram your cock into Yuka's pussy like a wild beast, your sister-cum-girlfriend moaning as your girthy cock stretched her pussy walls to the utmost limit, the mushroom-shaped tip touching her cervix and making her shiver. One easily lost count of how many times she orgasmed, both from your cock's size and the magic enhancing the pheromones of your pre-cum, increasing her erogenous sensitivity and healing the strain upon her vagina and womb.

Her ample bosom jiggled up and down like a pair of basketballs, firm and bouncy, and your lips suckled upon her as if expecting sweet breastmilk to flow like fountains.

"Oh yes, Yuu-kun! Fuck me just like this, breed me with your semen!" Yuka pleaded.

You shift your mouth to kiss and bite on her neck, and she shivered once again with slight pain as a red mark was left upon the skin.

As you fucked her, you moved one free hand to slap her buttocks, leaving a red handprint upon the firm globe of flesh. It jiggled like her boobs, and you smacked her again and again as if disciplining a naughty girl - a master disciplining his servant.

"Do you want to bear my child?" You questioned.

"Yes! Yes, I want it so much!" Yuka screamed.

"Then have your reward, good girl," You smiled.

Once again, your cock reached its climax, spewing a torrential flow of white, hot gold into her womb. Her eyes rolled back into their whites, her mouth open in a soft scream, and her body twitched and shivered under a barrage of electric shocks that overwhelmed her mind.

Finally, after a full minute, your climax subsided, and you gently removed your cock from her pussy, allowing the spillage to seep forth from the drainage hole. You kiss Yuka tenderly on the lips, and you rest your head atop her boobs. Together, the two of you slowly drifted off to sleep, nestled in the embrace of a warm blanket and each other's body heat.

And yet as fate would have it, another woman watched the entire thing happen from behind the door to the corridor.
