Chapter 174: Not just brother and sister anymore

Chris shivers the moment Mia’s soft, smooth hands timidly wrap around his erection.

She starts moving them slowly, up and down, almost as if she’s afraid of hurting him.

Chris throws his head back, his arms stretched across the top of the couch, as a wave of pleasure washes over him.

He sneaks a quick glance at Mia out of the corner of his eye.

I-It’s just a handjob, but... it feels so damn good...

Mia keeps stroking his cock, her hands moving up and down without stopping. Her movements are stiff and almost mechanical, like she’s following instructions instead of just going with the flow.

The intense look of concentration on her face feels so out of place — like she’s taking an exam instead of giving him a handjob.

Chris can’t help smiling.

A reaction that doesn’t go unnoticed.

"Y-You think this is funny...?" Mia mutters. "I-It’s already a big enough deal that I’m even doing this... k-keep making fun of me and I’m leaving!"

Even as she says it, though, she’s nowhere near as upset as she’s trying to sound.

"Y-You’re right, Mia... I’m sorry. And... I wasn’t making fun of you. I-I was just... happy..." Chris murmurs, his voice shaky with pleasure.

"So... I’m making you happy...? But... I-I’m not really doing anything special... I mean, you do way dirtier things with Isabelle and all those girls from Tsugumi who are crazy about you..."

"It’s not about what you’re doing. It’s about who’s doing it... A handjob from you means infinitely more to me than fucking any other girl at Tsugumi."

"I-I guess coming from a sex addict, that’s supposed to be a compliment..." Mia murmurs quietly, an awkward smile spreading across her face.

As she slowly gets used to the situation and starts feeling more confident, her grip around his cock grows firmer, and her strokes become steadier.

"W-Why...?" Mia asks, inching closer to him. "Why would something this simple with me mean more than doing so much more with someone else...?"

Sitting side by side, their bodies are pressed together now, thigh against thigh.

"Because..."

Chris pauses for a moment, trying to gather his thoughts and force his pleasure-clouded mind to work.

"...because I like you, Mia..."

She freezes. Completely still. She can barely even breathe as she stares at Chris with wide eyes.

There are so many things she wants to say that the words get stuck in her throat. Her mind goes completely blank.

Her heart pounds like crazy, and her face grows so hot and red that it feels like steam might start coming out of her ears.

"W-What’s wrong, Mia...? Did I say something I shouldn’t have...? I-I mean... I just meant... I like you as a sister. N-Nothing romantic, just to be clea—"

"I like you too..." Mia cuts him off, her voice barely above a whisper. "...I like you too, Chris..."

Now it’s Chris who’s completely thrown off.

"Y-You mean... you like me as a brother too...?"

"N-No, idiot. Stop pretending you don’t get it. It’s embarrassing enough having to say it once..."

"I get it. It’s just... I never imagined..."

Of course... so that’s what all those jealous outbursts were about...

Damn... Ren Toya was right after all. When it comes to understanding girls, that guy really is unbeatable.

Without thinking twice, Chris suddenly leans in and kisses Mia.

She freezes for a split second, caught completely off guard.

Then she kisses him back.

Their lips press firmly together. Their tongues entwine more passionately as Mia starts stroking him again, faster and harder than before.

Chris doesn’t just sit there either.

One hand slips beneath the oversized shirt Mia wears as pajamas, firmly cupping her breasts, while the other slowly moves lower.

It stops at her stomach, his fingertips resting on the waistband of her panties, silently asking how far he’s allowed to go.

When Mia gives him a firm nod, Chris slides his fingers lower, slipping effortlessly into her soaking wet pussy.

"Mmh... mhh... mmmhh...!"

Mia’s muffled moans of pleasure, swallowed by Chris’s tongue, echo loudly enough through the house to reach Isabelle’s ears.

She’s sitting on the floor outside the hallway door, touching herself as she watches everything through the peephole.

After what feels like an endless kiss, Mia finally pulls her lips away from Chris’s.

Without a word, she lowers her head, and her lips close around his erection, harder than ever and still slick with Isabelle’s juices.

Then she starts licking and sucking him with awkward, inexperienced movements.

Even so, it’s more than enough to drown Chris in a level of pleasure he’s never felt before.

"P-Please forgive me if I’m not as good as the women you’ve been with before... mmh... t-this... is my first time doing something like this..." Mia mumbles, her voice muffled around his cock.

"You’re amazing, Mia. I mean it... I’ve never felt this good in my life..." he says, his hands roaming over her body, touching her more intimately with growing passion.

"I’m... really happy to hear that... mmh... I-I really like you, Chris... I really do... but... I can’t stand the thought of you flirting with every girl you meet. That’s why I’ve never been able to let myself go with you... b-but, if you meant it when you said you like me, then... maybe... we could be exclusive..."

"So... are you basically asking me to be your boyfriend?" Chris asks, completely thrown off by how fast everything has happened, yet unable to hide his excitement.

Angry at him → Giving him a handjob → Giving him a blowjob →

Letting him kiss her, touch her, and feel her up → Asking him to be exclusive.

Everything happened so fast that Chris’s brain still hasn’t had time to catch up.

"D-Don’t get ahead of yourself, Chris... it’s a little too soon for that. Maybe... you could call it... our relationship evolving. Not just brother and sister anymore, but... something a little more. Or at least... we could give it a try and see how it goes..."

Chris gently cups her cheek and strokes it with his thumb.

"Okay, Mia... let’s give it a try..."

She looks up at him, her eyes shining with happiness.

At that exact moment, Chris cums in her mouth, while Mia’s own orgasm gushes out, soaking the entire couch.

"C-Chris... we’ve still got a little time before training... d-do you wanna just cuddle for a while...?" Mia stammers, her voice still trembling from the aftershocks of her orgasm.

"S-Sure... whatever you want..."

But right then, the hallway door suddenly flies open, and Isabelle tumbles into the room, her fingers still buried in her pussy.

Mia glares at her, face bright red and eyes burning with rage.

"I-Isabelle... you damn pervert... don’t tell me... YOU WERE SPYING ON US?!"

"Oops. Guess I got caught. Oh, by the way... from what I heard, things are getting pretty serious between you two... so, can I borrow Chris for one last half hour?"

"Not happening," Mia hisses.

"Oh, come on. I’m not ready to say goodbye to his dick without any warning. At least let me give it a proper farewell..."

Mia wraps herself even tighter around Chris, climbing onto his lap as she shoots Isabelle a threatening glare.

"I said no."

"Ugh... what a pain..."
