My Beautiful Girlfriend Cheated on Me, so I found Comfort in Having a Relationship with Her Little Sister - Chapter 2

With My Girlfriend’s Little Sister

“You are surely prepared aren’t you, senpai♡”

After we did it, both me and Yume are lying on the bed, naked.

“W-Well…”

To be honest, this rubber I brought is something I kept for doing it with Mana.

I never thought that I would use it for doing it with my girlfriend’s little sister, Yume.

Yume is looking at me with a big smile on her face.

“By any chance, have you had sex with Nee-san before?”

I shook my head at Yume’s question.

She seems surprised at my answer.

“Really? ♡”

There seem to be a bit of happiness on her expression.

In fact, the only couple-like thing me and Mana did is kissing.

We haven’t done anything else.

“Hmphhh…”

I can still Mana’s moans from the other side of the wall.

“Nee-san seems to be enjoying it.”

“Yeah…”

I wonder what kind of face Mana is making on the other side of this wall.

But, there is one thing I know for sure, the Mana right now is not the Mana I know.

“The first time I found out Nee-san was doing it is because I saw a used rubber thrown in the trash when I went inside her room. Of course, I thought it was senpai’s…but today, I found out that she is doing it with another man, that’s why I contacted you, senpai♡”

If Yume hadn’t told me about it, maybe I could’ve happily continued my relationship with Mana without knowing it.

No, that’s not true. I’m grateful Yume told me about this. After all, sooner or later, I will find out about this eventually.

“…thank you, Yume.”

“No, no, I’m glad that I got to do it with you too, senpai♡”

I don’t know if I have the right to say bad things about Mana, because I just had sex with her little sister. Even though I did it out of frustration she cheated on me, it doesn’t change the fact that I did it.

“Yume…don’t tell Mana about this—”

“Yeah, of course, I won’t tell Nee-san about this. But in return…you have to go out with me, senpai♡”

“Eh…”

I’m at a loss for words.

“I don’t know who is the person Nee-san cheated on you with, but senpai, you certainly don’t want to continue your relationship with Nee-san anymore, right?”

What Yume said is true, I certainly feel betrayed.

Mana, I thought I am the only one for you—

“Yeah…”

With a big smile on her face, Yume puts her hand together with a clap.

“Then, please go out with me…senpai ♡”

Mana said so and hugs me tightly.

If I think about it, Yume will fill the hole Mana left behind. She will heal me.

I can’t help but to grin at the thought of it.

I really am the worst.

“Then, I have a suggestion, instead of breaking up with Nee-san, we can just date each other behind her back♡ Come on, Nee-san cheated on you first, doesn’t that mean you can cheat on her too?”

That’s right Mana cheated on me first, so there is nothing wrong for me doing the same.

“I know Nee-san’s secrets, and on top of that, I’m the only one who can comfort you right now, senpai♡”

“Ahnnnn…”

Mana’s moans don’t stop.

She has been moaning nonstop all this time.

Her body seems really honest, she seems like enjoying it a lot.

“Mohh, senpai♡ Do you want to do it again?”

Yume kisses me on the lips as she said so.

I take her lips and kiss her passionately.

There is no reason for me to stay loyal to Mana.

Screw it, I’ll go out with Yume behind Mana’s back.

Mana and I will only have a formal relationship, that’s all, nothing more.

“Ehehe~ Pervert senpai♡”

Even after I finished doing it with Yume again. Mana moans still hasn’t stopped. So, I decided to leave.

“Nee-san, you really are such an idiot…then, see you senpai”

“Yeah, see you Yume.”

“Yeah!”

This is fine.
