It was after midnight when Glen heard someone fumbling with the front door lock before it finally opened. It was his sister Andrea and guessing by the noise she was making, he figured she must have been drinking. Down in the basement, watching an old Hollywood movie on TCM, he sat on the couch wearing a t-shirt and shorts. He had a can of beer and some chips on the table in front of him. It had been a relaxing, quiet, if somewhat boring weekend evening for Glen who was on break from college. He wondered what his sister had been up to, and then returned his attention to the movie.
Andrea was his fraternal twin. They were born minutes apart over 22 years ago. As children they had been inseparable, like so many sets of twins. But as they grew up, that changed. They remained close, just not that close. When they both set off for college, it furthered the separation. Andrea was developing into a nerdy math brain while Glen was deep into the humanities.
The house was quiet and Glen's attention had returned to the movie, but then he heard footsteps and his sister walked down, stumbling a few times, into the basement. She was wearing a long nightshirt and had pulled her chestnut brown hair back into a ponytail. She was wearing glasses, which always made her look more nerdy than she really was. Andrea walked over to the couch, her thin frame looking featureless under the long shirt. She slumped into the couch opposite Glen and squinted at the screen.
"What'cha watching?"
"'The Palm Beach Story.' It's directed by Preston Sturges. A true Hollywood classic."
"Oh gawd! Boring... You just love all those old-timey movies. How about something that was made in the last 10 years?"
"How was your date night?"
"It fizzled. Just ended up with Kate and Sarah and had drinks."
"Mmmm. I can tell. Still, sounds like you had a bit of fun. It's quiet as a church here at the house. Glad I'm heading back to college next week."
"Yeah, well, it could have been better night. Hey, come on. Let's change the channel."
Andrea's words were slurring as she lunged for the remote, grabbed it from Glen's hand and flopped face down on the couch and burst into giggles. She found it incredibly funny, and wouldn't let her brother have the remote, always holding it away from his outstretched hands as he tried to snatch it back. Desperate, Glen ended up tackling his sister, sitting on top of her, pinning her body down in hopes of getting it back. She, in turn, placed the remote under her stomach. When Glen reached under to get it he ended up tickling his sister. She laughed hard, which just made Glen want to tickle her more. She squirmed and as she wiggled her night shirt somehow slid up. She wasn't wearing any underwear.
Glen found himself looking at his sister's ass. It was a bizarre moment, yet he couldn't stop staring at it.
"Hey, cover me up!"
"No, I think I'll leave it as is, as punishment." He spanked her. Lightly.
"Ooooh! Naughty boy! Do you get your jollies spanking my ass?"
Glen didn't answer. He took his time and contemplated its soft, creamy curve, the pale color of her skin, the round moon-like globes of each cheek and the inviting dark cleft in the middle. And, to repeat, it was his sister's ass. His fraternal sister. Sibling. Family. Taboo...
"Did you know you've got a lot of nerve endings right at this spot?" Glen put the tip of his finger at the top of her crack and swirled it around softly.
"Like how it feels?"
"Mmmmm...yeah," was her muffled response.
He continued to rub the spot, but also began to slide his finger down her crack and then back up. Just a little bit more each time. Glen did it slowly, ever so slowly, but his heart was thumping madly. With each down stroke of his finger he moved it further into his sister's crack. Finally, he touched her anus. Andrea slowly turned her head and looked back at Glen. Her glasses were askew on her face.
