You're step brother and step sister! - A stepsister will always help if the girl doesn't want to

Fuck.

Well, not tonight, okay?

I'm so tired today.

There you go.

Have some wine, get some rest.

Come on.

Have you seen my sister?

Sister?

No, she's off again.

You know her.

Yeah, I know a little.

Forget it.

So I can't tonight, so I can't count on anything?

No way.

I'm here today, she's not in the mood.

That's okay.

Yeah, I guess.

Jerk off?

Yeah, maybe I will.

Don't worry, I'll do it another time.

Oh, oh.

What a skank you are.

I can't just stand on you fucking, fucking you.

That's what guys do.

Remember your ex at least.

I don't even want to.

Not just the guys, I think your sister's the same.

Oh, yeah?

Yeah, but he's thinking about dicks, man.

Well, I would know.

How would you know?

Well, we're part-timers, we'd probably fuck anyway.

Nonsense.

Don't you want to fuck her?

I don't know.

Well, she's all right, but I think she's wearing a helmet.

You think?

She just has nice titties for him.

Okay, I'm kidding, I'm not gonna fuck my girlfriend and my half-sister together.

Yeah, it's not right at all, you can't do.

How can you even think about that?

I don't think so.

That's right.

After all, she's a sister. You want a half-sister.
