Day three. Twilight was waiting for him at the foot of the couch when he woke up, and he pinched himself a second time to make sure there would be no repeats of the dreams he couldn't control and which seemed confidently set to send him spiraling into an aetherscape of depravity and reversed roles where Cadance would return home overjoyed that he'd manage to add his sister to his 'fuck-it list'. Though maybe that last part was semi-accurate.

"Hi, Shiny! Let's play a board game today!"

"Board games make you bored," Shining retorted, huddling up in his collection of blankets to hide his morning wood. He looked around the living room as though someone might emerge from the corner to offer a distraction and allow him to run to the bathroom and calmly ease his soldier down from attention. Instead, he was trapped with Twilight, who didn't seem interested in letting him up until he'd agreed to spending more time with her. Time spent next to her, looking at her, hearing her, breathing the same air, feeling the hitches in her breath the same times as his...

"What about Ponopoly?" Twilight asked, holding the board up and shaking the pieces inside.

"Sucks with two people. And capitalism is a terror inflicted on the working class by opulent masters."

"Croup?"

"You always just guess Hoofington Honeymustard in the Stable with the Horsehoe and then ask to restart when you don't get it. Over and over again."

"It's optimal!" Twilight shouted. She grabbed a throw-pillow from the end of the couch and threw it at her brother. It bounced off his head harmlessly and landed on the ground with a feeble 'pap'.

Shining raised an eyebrow, but said nothing. Hands still tucked in his blankets, covering his erection.

"Pony Risk, then?"

"You cheat. And why are all your games pony-related, anyway?"

Twilight shrugged and laid back on the couch, lounging her head over the back and kicked her feet absentmindedly. "I dunno. I just think they're cute, I guess."

Shining sighed.

"I'll play a board game with you, but can I at least get up and have some breakfast first?"

"I already made breakfast!" Twilight yanked a plate out from the aether, or maybe just below the table where Shining couldn't see, and presented a happy-face of bacon accompanied by two over-easy eggs and a slice of what looked like sourdough toast. Since when did they have sourdough?

"Oh... thanks. I guess I'll just... eat that here then. Without getting up."

"Okay!"

Twilight sat and smiled as her brother silently at his breakfast. He chewed quietly on the crunchy bacon pieces and wondered what kind of signal it would take to tell his penis it was finally time to calm down because no, sorry, they would not be getting any action today, no matter how nice Twilight's tits looked in that blouse or how close she was sitting to almost being on our lap, bouncing up and down on us instead of just the couch cushions...

Ahh. Cut it out.

"Ooh, I know! What about Body-Tangle-Tornado?" Twilight leaned toward her brother and squished her breasts into his legs, whether or not she was aware of it, rubbing the two fleshy pillows up and down just below his concealed hard-on.

Shining gulped down his last piece of bacon nervously. "Uh... isn't that just a knock-off of Twister¹? And, isn't Twister, uh, that game where you, uh, you know..."

Twilight rolled her eyes. "Who cares if it's a knock-off? It'll be fun! Come on, Shiny, you haven't wanted to do anything during my visit so far."

"That's not true. I wanted to sort things in the garage, and you could have done that with me. I just didn't tell you or ask you for any help." Shining Armor put his unfinished plate back onto the living room table, leaving one egg and half a piece of toast he somehow couldn't take a bite of without thinking of Twilight's ass in his face, bent over to pick up something or other, or maybe just purposefully squishing both cheeks into him, letting him get a deep sniff of how wet she'd become underneath her panties...

Focus. Four more days. You can do this.

Shining gulped. "Alright, fine. We'll play... Body-Mangle... whatever. Just lemme use the bathroom and uh... brush my teeth, okay?"

"Okay!" Twilight beamed and hugged her brother. Her breasts squished even harder into his chest than they had his leg, and he swore he felt to little pointed bumps rub up against him through her shirt. But before he could be sure, Twilight was off him, and running to the bedroom with her stack of board-games, ostensibly to set up the evening's temptation in colorful play-mat form.

In the bathroom, Shining splashed his face with cold water a few times before finally convincing his hard-on to go down. After that, he took a nice long piss, because he needed to, and because it was impossible to think about Twilight's ass while he was doing so. As soon as he finished, the pajama pants came back—but the momentary respite was nice, almost necessary.

How are we going to do this?

Just don't think about it too much. Go in there, play one round with her, and if things get out of hand, remember your wedding vows...

I, Shining Armor, vow to fuck my sister during Arbitrary Quarantine Week until she's dripping my cum out of her pussy, and to pound her over the kitchen table on the day my wife comes back so she can walk in and cheer us on...

"Shining, are you ready? I have the game all set up!" Twilight shouted from the other room, her voice loud and carrying down the hallway and through the communal bathroom door.

As ready as I'll ever be.

"Yeah, I'm... ready. Be there in a minute, okay?"

"Okay!"

Shining splashed his face with an extra large handful of cold water and toweled his face off before exiting the bathroom. Then down the hall and to the master bedroom, where his sister's pajamas were still lying somewhere from the night before...

How do you play anyway? Isn't it just an excuse to mash your face into someone else's crotch while touching a colorful circle?

"Left foot blue!" Twilight said, letting the spinner land in place and grinning before it had even settled. "Come on, Shiny. This'll be fun!"

Shining put his right foot on the blue circle, then remembered his directions and adjusted accordingly. Up and right were even hard to remember lately, it seemed.

"You spin next." Twilight offered the spinner forward and smiled.

Shining attempted his best fake grin and flicked the spinner, watching it as it turned over the wheel of colors and finally landed on...

"Right hand pink!" Twilight said, announcing like she was programmed along with the spinner.

"I can read, you know."

Twilight giggled. "I know, but it's more fun if you say it out loud. Like the commercial!"

"What kind of books have you been reading lately anyway?" Shining Armor asked. He searched around the mat for a pink circle and found the only unoccupied one directly across from Twilight, overlapping her like an 'x' in tic-tac-toe. Shining could see her stomach peeking out from underneath her blouse, her belly-button and taught skin leading away and underneath her tight-fitting jeans. Shining wiped a bead of sweat off his forehead with his spare hand. "Seems like you're way more peppy than usual. Romance novels that good?"

Twilight rolled her eyes and flicked the spinner. "Ha ha, very funny. I've actually been reading a biographical historical volume of Equestrian genealogy. Some of the ancient lineages are really fascinating..."

I wonder if there's a branch missing in our family tree somewhere there. Maybe we could break it off and not have any more bothersome questions.

"Right foot green!"

Shining scanned the play-mat again. Plastic was already slipping underneath his feet, wiggling him closer to the only other player on the board. His right foot found the green circle, and now he was practically mounting her. His crotch was inches away from Twilight's butt, squished into what seemed to be another perpetually under-sized piece of clothing. Twilight was staring at the wall, which meant, before he caught himself, Shining could leer continuously at her backside, imagining sliding just a little further forward and squishing his rapidly-hardening cock in-between her cheeks...

Without warning, Twilight had completed the fantasy, smooshing her butt backwards under the pretense of stumbling toward the reach of the spinner. Her jeans rubbed up and down on Shining's dick underneath his pants, instantly making him hard and further complicating the prospect of further gameplay.

Twilight picked herself up after a few seconds sprawled out, but the damage was done. She looked like she'd gone spread-eagle just to push her butt up into the air...

"That's it," Shining said. "I'm tired. Time for bed."

"But it's four-thirty in the afternoon!" Twilight whined. She picked up the digital clock on the bedside table and pointed at it with an exaggerated look on her face. "See?"

"Yeah, well, all this staying inside doing nothing has really got me beat. I'll see you in the morning."

Twilight huffed and crossed her arms across her chest as Shining left the room. She began packing up the plastic mat after a minute or two, grumbling under her breath.

Author's Notes:

1: Apparently no-one knows what Twister was anymore, but it was a game with a plastic mat and multi-colored circles and you used to play it at parties where people wanted an excuse to get in awkward sexual situations with each other. It was popular. Trust us. - Ed.
