We got the hotel, checked in, ate dinner at the restaurant and retired to our room for the night. I went into the bathroom and changed into my nightshirt, a flannel plaid eyesore that was warm and fuzzy. When I emerged I handed Gretta my extra which was more of an oversized T-shirt, but more than enough to provide her with modest nightwear. At least, I thought that was the case.
When she emerged wearing my nightshirt, I realized that it was much shorter then I remembered and exposed all but the top three or four inches of her remarkable legs.
I put my eyes back in my head. "Oh my… Gretta, I'm… I'm sorry. Look, my shirt is bigger… Uhm, we can switch."
But she only laughed. "I guess I'll stick with what I'm wearing, if I have to choose between a little skimpy and butt ugly, I'll stick with what I've got."
I could see the sense in what she was saying, after all, the shirt wasn't a whole lot shorter than the skirt she had been wearing all day.
We both curled up on opposite ends of the couch, switching through the cable offerings on the TV. We watched the local news and a family movie on HBO.
It was still pretty early in the evening when Gretta started channel surfing looking for another movie when she stumbled across the hotels' erotic channel. As luck would have it, the title of the movie just beginning was "Sister's Helping Hand".
Oh gross!" Gretta squealed. "Is this what I think it is?"
It looks like it. Why don't you go back to HBO and see what's on."
"In a minute. I want to see if the movie is as disgusting as the title."
Unlike many pornographic films, the movie was not disgusting. It consisted of a series of interviews with a supposed brother and sister who looked remarkably alike interspersed with short snippets of the same brother and sister m**********g with each other.
Unlike many videos of this type, the interviews seemed genuine and the snippets showed what seemed to be two very aroused young people teasing each other. They acted with innocent sincerity and increasing excitement as they gradually moved from flirtatious conversation to gradual undressing and finally to mutual m**********n. This grew bolder as the movie progressed. At first, the girl was doing it sitting across from her "brother" while he sat and watched. Then they were sitting next to one another doing it together. Finally, they were touching each other, whispering together as they grew more aroused.
I was glad to be sitting down. As the video unfolded I found myself becoming quite aroused. I chalked it up to being in close quarters with my sister for so long. It had been several days since I had the opportunity to relieve myself and I figured the s****l pressure was building up. I promised myself a good climax in the shower when I got up in the morning and in the meantime I could just suffer a little.
Gretta was utterly silent as we both watched. Her face was flushed and her short shirt had ridden up exposing her panties but she didn't seem to notice. Her gaze was riveted on the screen as the girl rubbed her brother's erect c**k against her p***y. The girl was whispering "You know we can't f**k, don't you?" as she continued rubbing. Her brother nodded and shuddered.
In the interviews, they each explained that they had begun doing it during a dry spell during dating and they gradually become sexually involved with each other. In each snippet, they were closer to each other, wearing less clothing and using more and more explicit language. You could tell that it was only a matter of time before their self-discipline broke down entirely.
I thought we had been watching for about twenty minutes when Gretta turned to me. "This really is as disgusting as the title, you don't suppose that they're actually related do you?"
I looked at her. "No, no, they're just a couple of actors reading a script… Uhm, in this case, a really sick, perverted script."
"You said it." She switched back to HBO. I noticed that she seemed to be breathing a little heavily and chalked it up to outrage. I also saw that while it seemed we had only been watching for a short time, an hour had gone by; not twenty minutes.
We watched for a while and Gretta was really quiet.
That's illegal isn't it?"
What?" I was already absorbed in the movie, an action flick with plenty of explosions and a half- dressed romantic interest clinging to the leading man adoringly.
The brother and sister thing. silly. Isn't it against the law?"
I thought for a minute. "I think it is in most cultures, but in some places, people do it."
What places?"
"Well, in ancient Egypt, the royal family always married brother and sister."
"That's ancient history. Do people still do it today?"
"What? Allow marriage between siblings? I don't think so, but apparently some people still want to… Or at least want to fool around."
That's sick." She looked pale, like she was going to throw up.
I know. I guess you'd have to be pretty hard up to try that.
We continued watching the action movie. I went to the bathroom to answer a call of nature. When I returned in a few minutes, Gretta had been channel surfing and apparently returned to the same movie we'd been watching earlier. She was flushed and leaning forward in her seat as if to get a better view and she jumped when I walked in the room.
She fumbled with the control, hitting several buttons before she clicked the "off" switch. "I guess we'd better turn in, there's nothing good on."
I agreed, peeled off my nightshirt and clad only in underwear walked into our shared room. Ignoring a playful wolf whistle from Gretta, I pulled my covers back. We each climbed into our bed and shut off the lights.
As we were drifting off to sleep, Gretta asked sleepily, "Do you think I'm attractive?"
"Of course, why do you ask?"
I was just wondering, sometimes I think I'm a little too skinny."
You're just fine. If you weren't my sister, I'd date you."
Really?" She sounded very awake.
In a New York minute, sis. Now, can we get some shuteye?" My eyes grew heavier by the moment.
Thank you, David." Softly, the words drifted to me from across the room.
You're welcome." I drifted off into sleep.
