My Beautiful Girlfriend Cheated on Me, so I found Comfort in Having a Relationship with Her Little Sister

Chapter 11

“Senpai♡”

After school, as I’m heading out of school, I meet Yume standing at the school entrance.t

“What’s wrong?”

“Looks like Nee-san is going to a nearby karaoke now, you know?”

“Yeah, she sent me a message saying she can’t come home with me today.”

I say so and start to walk past Yume.

It’s raining heavily outside.

Ah, when did it start raining?

I didn’t even know it’s raining.

Hmm, I didn’t bring an umbrella. Well, I guess I just have to walk through the rain and take a nice hot shower as soon as I get home.

I turn my head down and start walking.

Even though my body is wet from the rain, strangely I don’t feel cold at all.

The rain doesn’t show any sign of stopping.

“Senpai, here. A folding umbrella♡”

When I turn around, I see Yume following me with a folded umbrella in her hand.

“No…you should use it Yume. Thank you, but I don’t want you to get sick.”

“T-Then, how about we share the umbrella?♡”

“Well, okay then. Thanks.”

Because it is wet, Yume starts to take off her blazer and put it inside her bag. However, I noticed that I can see her black bra through her thin uniform.

—oh no.

“Yume, I’ll hold the umbrella.”

“Okay, senpai”

I can’t help but to look at Yume’s bra.

I know I shouldn’t do this, I know this is wrong, but still…

If Mana had sex many times with that guy, perhaps I can do it with Yume once more?

Mana is the one who cheated on me first after all.

If that the case, I can do it with Yume not just once, but hundreds of times, right?

I’m getting excited just by the thought of it, but somehow, I managed to hold myself back from smirking.

That’s right, just consider it as a practice.

If Mana is getting better at it, I’ll be ashamed if I can’t do it properly when I have sex with her.

I need to practice having sex a lot with Yume.

“Yume, do you want to go to karaoke now?”

“Yeah♡ Sure.”

Yume likes me too, right?

Then, if she can have sex with me, she will definitely be happy too, right?

“Can we stop by a convenience store first?”

“Yeah, of course♡”

I wonder if one box would be enough…

Let’s just buy three boxes just in case.

I can’t take any chances, because if I get Yume pregnant, I’ll be a worse person than Mana.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As soon as we arrive at the private karaoke room.

“What kind of songs do you sing, senpai?”

I take off my blazer and hang it on the door so that no one can see us from outside.

“Senpai?”

I grab Yume by her neck and bring my face close to hers.

Then I start kissing her. I start putting my tongue inside her mouth.

It’s not fair if Mana is the only one who can do it.

That’s why, I’ll have some fun too.

I really want to do it with Mana, but she just won’t do it with me.

That’s why, I’m going to have sex with her little sister.

I wonder how many minutes it has been since I start kissing her…

I gently let go of Yume’s soft lips.

“Sen…pai?”

Yume said so with a debauched look on her face and drool all over her face.

Ahh, I can’t hold myself back anymore.

I push Yume down onto the sofa.

—I really am crazy.

Then, Yume smiles.

“It’s really though, isn’t it senpai? You can do whatever you want with my body today♡ Senpai, Nee-san is cheating on you and she is having lots of sex with that guy, so there’s no problem with you doing the same, right? Senpai, I’m not like Mana Nee-san, you know?♡ You can do whatever you want with me, I will never cheat on you.”

—is that so? I see.

—then, I’ll use her body to please me however I want.

“Aaaaaaaaaaaaahhhhhh!”

Me and Yume had sex again today.

I didn’t stop screwing Yume even when she was saying something to me or when she looked like as if she was about to pass out.

Because she told it herself, didn’t she?

I can do whatever I want to her body.

So I just did what I’ve been told.

I should’ve bought some more, three boxes weren’t enough.

Even though I felt horrible about myself, it was really great.
