Volume 9 Chapter 4 The Older Sister I Yearn For*
Edited by: Kanaa-senpai
Since we had successfully become a couple, I decided I should make a “Vow”¹ to her, just as I had with my other lovers.
”Clarissa-san, please don’t be startled by this.”
”I don’t think much could surprise me more than your confession, Daisuke-san, but what is it?”
”I Vow to the Gods that until your heart truly wanders from me, I will never betray you, never flee from you, and I will protect you forever.”
”Wh-! A Vow!?” Clarissa exclaimed.
In a workplace where duels are nonexistent, a Vow must be a rare thing. I had given her a warning, but she was still taken aback.
Clarissa lived alone, having moved out of her family home, and seemed relatively distant from her parents. Though there haven’t been talks of arranged marriages lately, she was troubled by their constant nagging about her remaining single.
I’ll have to go pay my respects eventually, so I really do need to protect her. I don’t think they’d oppose a relationship with a B-Rank Adventurer, but optimism is a dangerous thing. Wealthy merchants can sometimes be more of a headache than the nobility.
”I have to fulfill this Vow properly. If anyone stands in our way-be it parents or dragons-I’ll blow them away.”
”The parents are one thing, but you mustn’t go against a dragon, okay? We finally became lovers; I would be so sad if you died, Daisuke-san,” Clarissa replied.
”You’re right. Then if a dragon shows up, we’ll run away together.”
”Yes… ♡”
(Well, the dragon part is a joke. For now, at least.)
The carriage carrying the two of us wound through the city streets under the cover of night. Our destination was the same hotel where the three girls from Gale had their first time. The dark roads were invisible from the carriage, turning the interior into a private sanctuary where we embraced and shared deep kisses.
”You’re more passionate than usual. It makes me so happy,” Daisuke said.
”Haa… ♡ Being your lover, Daisuke-san… my heart is just overflowing with joy ♡”
Clarissa was usually so ladylike, but her face, flushed with heat, was incredibly cute. As soon as we reached the hotel and entered the room, we fell into each other’s arms. She hugged me so tightly that I could feel her soft breasts being squished against me. Hers were the softest of all my lovers.
”Daisuke-san… would it be okay if I kissed you… differently than usual? ♡”
”I’d be delighted,” Daisuke replied.
”Ufufu… ♡”
Exuding a mature allure that matched her age, Clarissa was more aggressive than I expected. She moved from light pecks to a deep, tongue-tangling embrace. It wasn’t bad at all to just let her take the lead for a while.
As we kissed, our hands began to roam. I started by stroking her back and neck, then slowly let my hands slide down to knead her bottom. Those cheeks, which I had watched jiggle so many times, were just as soft as I’d imagined. Since her job wasn’t physical and her Level was low, her entire body was wonderfully soft.
”Ah… ♡ Please don’t make them jiggle like that ♡ I’m actually a little self-conscious about it, you know?” Clarissa whispered.
”You aren’t fat at all. This is part of your charm, Clarissa-san.”
”Nn… ♡ Oh, you really are something, Daisuke-san… ♡”
As I continued to massage the area she was so worried about, Clarissa smiled happily, her insecurities melting away under my touch. I decided to move on to her clothes. While pulling her close with one hand, I used the other to work through the buttons of her blouse and then the clasp of her skirt.
This is what high DEX² was made for. Clarissa returned the favor by unbuckling my belt. Beneath my underwear, my c**k was already engorged and thrashing, demanding to be released.
”Daisuke-san, you’re so excited for me… I’m so happy… ♡”
”You’re already wet too, Clarissa-san.”
”You… you mustn’t say that! ♡ It’s embarrassing! ♡” Clarissa cried.
The panties hidden beneath her fallen skirt were already soaked. It seemed she found the fact that I knew she was wet more embarrassing than actually being naked. I lifted her in a bridal carry and laid her gently on the bed.
”By the way, I was truly shocked when you actually went to the eleventh floor of the Dungeon,” Clarissa said.
”Sorry, I just wanted to surprise you.”
”Geez… ♡ You really can be such a child sometimes… ♡”
Since she wasn’t actually angry, I muffled her complaints with a kiss. I slid off her blouse and unhooked her bra, finally coming face-to-face with her bare breasts.
Her whole body was flushed a pale cherry-blossom pink. I had been admiring them from afar for a year, but seeing them for real, they looked so supple, swaying ever so slightly with every breath she took.
”Daisuke-san… ♡”
Sensing she wanted to be touched, I cupped them from below. My palms were filled with a heavenly, fluffy weight. They were more modest than Regina’s or Ines’s, but a bit larger than Cassandra’s. In my Previous Life³, she would definitely have been considered busty.
”Nn… ♡ You’re even gentle on the bed… ♡”
”Because you’re precious to me, Clarissa-san.”
”To hear you say that… I feel like I’m dreaming ♡”
I massaged them slowly and gently. Those fluffy mounds changed shape freely with my movements. They were soft as a slime, yet possessed a distinct warmth that proved she was a living woman.
In contrast to the ever-shifting mounds, the tips began to engorge, becoming red and firm. I didn’t touch them directly yet, instead lightly grazing the areola with my nails.
”Nnn… ♡ It’s so frustrating… ♡ You can go harder, it’s okay! ♡”
Since that’s what she wanted, I increased the pressure. I pinched her n**ples-now the consistency of gummy candy-and rolled them between my fingers. Judging by her reaction, a standard amount of force was exactly what she needed.
”Ah… ♡ Yes! ♡ That feels so good! ♡ You’re so good at this, Daisuke-san… ♡ Nn! ♡”
”Thank you,” Daisuke said.
(It’s because I’ve put in a lot of practice, I thought, but there was no need to say that out loud.)
While the massage was nice, I wanted to finally taste her. I leaned down and began to suck on her n**ples, teasing them with my lips. Her scent was faint and sweet. I took her into my mouth, swirling my tongue around the tips. I flicked my tongue against the areola while using my fingers to provide the same stimulation to the other side.
”Nn… ♡ It feels incredible… but Daisuke-san, you’re ready too… aren’t you? ♡”
”I am.”
I loved her breasts, but I couldn’t stop there. I kicked off my remaining clothes and unleashed my throbbing c**k.
”It’s so big and powerful… ♡”
”Let’s get the rest of yours off too,” Daisuke said.
”…Yes… ♡”
As I slid her underwear down, I saw that her golden lawn had been neatly trimmed. It was a clean, square shape, clearly maintained. Since she was a mature woman, it should have been more overgrown, but she must have groomed herself just for today. Beneath that, her secret place was already glistening. She was more than ready.
”Please… don’t stare so much… it’s embarrassing ♡”
”But it’s exciting, isn’t it?”
”…♡”
Too shy to answer, she simply nodded while shielding her chest and groin with her hands. I leaned in for a kiss while sliding my hand between her thighs to check her condition. Just a touch elicited a lewd, squelching sound. As I slid a finger inside, the slickness and give of her body told me she was perfectly prepared to receive me.
When it came to Clarissa, her best feature was her bottom. Her breasts were great, but every time I saw those thick, soft hips from behind, I had fantasized about taking her from the rear. I had her get on all fours and pressed my head against her dripping entrance.
”Clarissa-san, I’m coming in.”
”Yes… Please, make all of me yours, Daisuke-san… ♡”
Just as I was about to slide in, a thought occurred to me. Wait, was she on birth control?
”Clarissa-san, are you taking contraceptive medicine?”
”No, I’m not taking any, but it’s okay,” Clarissa replied.
”Are you sure?”
”I’m not getting any younger, so I’ve decided that I’m perfectly fine with having a child right now.”
”I think you’re still plenty young…”
”Thank you ♡ But Daisuke-san, you wouldn’t be the type to break a Vow, would you?”
”Of course not.”
”Then there’s no reason to wait, is there? ♡”
”I can’t say no to that,” Daisuke said.
”Ufufu… ♡ Then it’s settled! ♡”
Begging to be bred, Clarissa had effectively Class Changed⁴ into a truly naughty older sister. A raw creampie is every man’s dream. I had zero intention of refusing.
”Alright, here I come.”
”Please, come deep inside me! ♡”
I gripped her ample hips and drove my waist forward, burying myself inside her with a wet thud.
”Haaan! ♡ Right to the back, all at once! ♡”
The impact against her Portio⁵ seemed to send her over the edge immediately. Her face melted into an expression of pure ecstasy. Her walls embraced my c**k with a desperate heat. Losing all restraint, I began to hammer my hips against her.
”Ah! ♡ Ah! ♡ Daisuke-san, you’re so intense! ♡ Even for the first time, it doesn’t hurt! ♡ It feels so good! ♡” Clarissa moaned.
”Let’s make it feel even better.”
With my hands, I savored the plush flesh of her waist; with my c**k, I savored the soft, tightening grip of her depths. Every time I scraped against her internal folds, more love juice sprayed out. Clarissa, her hair a mess as she cried out in pleasure, was utterly bewitching.
”No…! ♡ I’m going! I’m going to finish! ♡ My insides are being turned into a mess… ♡ It feels so good… I can’t think…! ♡”
”Don’t think. Just take it. I’m going to breed you just like you wanted.”
”Aaaahhh! ♡ I can’t stop it! ♡ Daisuke-san’s c**k… is making me c*m! ♡”
”There! Take it! Get pregnant!”
”~~~~! ♡”
With a final, deep thrust, I emptied myself into her very depths. Receiving the flood, she hit another climax, her back arching as her walls clamped down tight, drawing every drop of sperm up toward her womb.
”Clarissa-san, did that… satisfy you?”
”H-haah… y-yess… ♡”
Clarissa collapsed onto the bed, her body twitching. She managed to answer, but her voice was a slurred mess. I might have pushed her a bit too hard for her first time.
* * *
”Phew… that’s a load off.”
I flushed the semen-stained tissue down the toilet. (Slime-san, thank you as always!) Where am I? My own bathroom at home, obviously.
The part about the Vow was true, but I didn’t actually sleep with Clarissa-san today. After dinner at the restaurant, I walked her home and we parted ways with just a kiss and a hug. Since becoming a couple, she’s been more forward, but I told her we didn’t need to rush. It wasn’t just about her body; I wanted to be with her because I genuinely like her. Taking it slow is just fine with me.
(But man, now that we’re officially dating, my fantasies about Clarissa-san are really hitting a new level. That curvy, soft body of hers is just too erotic. She might be self-conscious about it, but that plushness is exactly what makes her so charming.)
