My sister (Emily) brought her boyfriend home.
His name is Ryan, and he's quite handsome.
The two of them went into Emily's room.

A little later, I brought some snacks into Emily's room.
From our conversation, Ryan seemed like a really nice guy, and we had a great chat.
Emily said, "Get out now," and kicked me out.

Emily: "Sis, don't come in."

Me: "Okay, okay."

I went downstairs and after a while, I quietly went to check on them.

He: "Your sister is here, isn't it bad?"

Emily: "It's fine, let's do it."

(What are they going to do?)

I heard rustling sounds.
Sounds like kissing.

(Are they going to do it?)

Emily: "Ah, come on."

The bed creaked.

Emily's voice sounded intimate.

Emily: "Mmm, I'm going to..."

I heard heavy breathing.
I quietly went downstairs.
After a while, they both came down.
We chatted a bit, and then Ryan left.

Me: "Emily, what were you doing?"

Emily: "Just playing some games."

(Even though they were doing it...)

A few days later, Ryan came over while Emily was out.

He: "Is Emily here?"

Me: "She's not here right now, she's out."

He: "I see..."

Me: "Why don't you come in and wait?"

He: "I'll do that."

Ryan came into the house.
I served some snacks in the living room.

Me: "Did you and Emily do it?"

He: "Yeah, we did."

Me: "I see..."

As I said that, I deliberately unbuttoned my shirt to show my chest.

He: "Sis, your chest is showing."

Me: "Whose is bigger, mine or Emily's?"

He: "Yours."

Me: "Want to touch?"

He: "Is it okay?"

Me: "It's fine."

Ryan touched my chest.

He: "It's big and soft."

I took off my shorts.

He: "Sis, are you not wearing anything?"

I wasn't wearing any underwear.

Me: "Want to go to my room?"

He: "Emily might come back."

Me: "She won't be back until evening. Don't you want to do it with me?"

He: "I do."

I took Ryan to my room.
We got into bed and kissed.

Me: "Was it just normal with Emily?"

He: "What do you mean by normal?"

Me: "I'll teach you adult stuff."

He: "What's adult stuff?"

Me: "You put it here."

I pointed to my backside.

He: "That's the back."

Me: "You've never done it, right?"

He: "No."

Me: "Want to try?"

He: "Yeah."

I lay on my back and used my fingers to prepare myself.

Me: "Put it in."

Ryan put it in.

He: "Wow, it's tight."

Me: "Mmm, more."

He pushed in.
I couldn't finish just with that, so I touched myself.

Me: "Ah, I'm going to... you can finish inside."

He finished inside.

He: "That was amazing. Thank you, sis."

Me: "I'll let you do it again, but keep it a secret from Emily."

(Will Ryan come to me now?)

A few days later, Ryan came over when Emily was home.

They went into Emily's room.

(Are they going to do it again?)

After a while, I went to check.

Emily: "It hurts, what are you doing?"

(Emily's voice, "It hurts"?)

He: "It's fine, let me do it."

Emily: "No, that's the back."

He: "I can finish inside here."

Emily: "How do you know that?"

He: "Well, someone told me."

(Ryan, don't say it!)

He: "A woman."

Emily: "I have a feeling I know who."

(Did she find out?)

Emily: "I don't want to lose, do it there."

...

Emily: "It hurts!"

Emily was crying.

He: "I'm finishing!"

It seemed to be over.

Emily: "I won't ask who, but from now on, I'll do it, so don't do it with anyone else."

I quietly went downstairs.
Ryan left too.

Emily: "Sis, did you do it with Ryan?"

Me: "I don't know."

Emily: "Well, it's fine. From now on, I'll do it, so you won't have a chance."

Seems like I can't win against my sister...
