Are you insane? Of course I do!

Rebecca slips her hands around you and soon your face is nestled into her long hair, and you can feel her naked boobs pressing into your chest.

Ohhhhh.... your mind goes into lust overdrive feeling those mounds pressed between you.

You put your arms around her and you feel the skin on her naked back. Oh, FUCK, this is so HOT!

Rebecca humms with pleasure and presses her body into you, and then suddenly you realize: SHE CAN FEEL MY HARD COCK.

[This is too easy, she thinks. It's gonna take almost no time at all before he's dolled up and sucking Dave's cock like prostitute.]

Shit, shit, shit! I have a hard-on for my sister, and SHE CAN FEEL IT. Fuck!!

You desperately try to stick out your but to maintain some distance, but Rebecca is having none of it. She snakes an arm around your waist and pulls you in, then grinds against your hard cock, looking your straight in the eyes.

"Feels like someone is having inappropriate thoughts, aren't you, Paul?"

"No!" you say, too quickly, trying to pull away.

"Really? Then what's this?" Rebecca boldly grasps your hard penis through your pants. "You have something hard in your pocket, maybe? Then take it out and SHOW ME," she challenges.

"Alright, fine! But, gimme a break! You're topless and gorgeous. I'm only an ordinary man!"

[Not for long, Rebecca grins to herself.]

"Remember what I said about having only appropriate thoughts? And creating a comfortable, mutually respectful environment? "

"I can't help myself," you whine. And as if to prove your point, you stare right at her breasts, which are standing proud and pointed directly at you. Oh, if only you could feel them in your hands...

"Regardless, you failed this basic test, and so you'll need to be punished."

"Punished?" you squeak.

"Yes, punished. Now, since it is your first offense, I will give you a choice."

"A choice?" For some reason, all you can think to do is repeat everything she says.

"Yes, a choice. Your first choice is to go tell MOM exactly what you were thinking when you got a hard-on while hugging your older sister, and then to let Mom decide your punishment."

"Ack!" A strangled sort of sound comes out of your throat.

"No? Okay then, your second choice is to go tell DAVE exactly what you did, and then ASK HIM TO GIVE YOU A SPANKING."

"WHAT? A spanking? From DAVE?" Your eyes go wide with shock.

"He is the new man of the house," Rebecca points out. "He is your Step-Dad. Your parental guardian. Your FATHER."

"Aah, aah, aah..." you can't seem to form words anymore, the idea is too horrible.

"If it helps, I'd be happy to go down and explain what happened to Dave!"

"NO!" you shout, before realizing that others can probably hear and lowering your voice. "Isn't there something we can do, you know, without telling Mom or Dave?" you whisper.

"Well..." Rebecca taps her chin for a while. "I suppose, if you were to do my laundry, then I could perhaps be persuaded to not tell Mom or Dad."

"Do you laundry?" You have a sinking feeling. Damn it. "This was all a set-up, wasn't it?"

Rebecca laughs.

"Yes, yes it was! You should have seen your face! Oh, it was so perfect!"

"Okay, okay, you got me. Now, could you please put a shirt on and we can forget this whole thing ever happened?"

"That depends, are you going to do my laundry for the summer?"

"WHAT? I still have to do your laundry?"

"Do you still have a hard-on?" she challenges, pulling you into a hug and grasping your cock. "Goodness! I think it's even harder than before! Does talking about being SPANKED by DAVE turn you on?"

"NO! HELL NO!"

"Seems like it does," she manipulates your cock. "Wait'll I tell DAVE and MOM that you get a hard on thinking about being spanked by them!"

"Spanked by THEM? What the HELL?"

"Are you going to do my laundry or not?"

You look around the room and notice, for the first time, piles of dirty clothes all over. And a lot of it is delicate office wear with expensive-looking fabrics. You wonder what you're getting yourself into.

"Maybe you're getting turned on by thinking about doing my laundry," Rebecca says, squeezing your cock some more. "Are you?"

With her words you can't help but think what it would be like to have a JOB basically collecting her dirty clothes, her smelly, wonderful, sexy dirty clothes, all those much-too-small panties, those bras, the blouses and skirts and socks and pantyhose smelling all her feminine smells...

"No!" you say quickly and too loudly.

"That's not what I'm feeling," she says, wickedly. "Now what is it? Do my laundry, or I spill all to our parents? Your choice!"
