She wants to cut to the chase.

"Listen- let's make this simple," the Stepsister says, "The pictures were designed to get you horny and into bed with her.
You're clearly the former and right next to the latter."

Kirk pauses.
He can't deny either thing.

"Lori- don't talk like that," Jenni says.
"Why? He's your Boyfriend."
"And you're my Sister."
"STEP-sister. I first met you when I was 22 and your Dad married my Mom.
We are NOT related."

Jenni can't argue with that.

"Besides, I've seen you check me out," Lori says, "It's alright- I'm not judging. I was certain not looking away as you posed nude for that guy."
"But we're tied up!"
"Yeah. It's kind of hot, isn't it? I mean, with him here and in your House...and with the door locked."

Kirk nods.
He definitely locked the door after he got in and before he saw the duo.

"Let's just cut to the chase. I know that you want to kiss me."
She gets eye-to-eye with Jenni.

Kirk's Girlfriend doesn't deny this.

"This just stays between us, right?"
Kirk nods.
Lori nods.
