Back when we were kids, my identical twin sister Arrie and I sometimes played a game called Double Dog Dare. Now, out of the blue, she said, “I double dog dare you to photograph me and Brian making love.” She wasn’t even it. We were in the living room of our brand-new apartment, all fresh and almost bare—our apartment, not us—and smelling slightly of fresh peach pink paint, both us and the apartment, because we’d spent the day painting the living room.

We were so pleased to be out of the dorms. Daddy had allowed us to move into an off-campus apartment if we both got straight-A’s and if we earned enough money over the summer to pay the security deposit plus two months’ rent. That didn’t leave us a whole lot of money after we’d bought the paint and the darling pair of armchairs. “Figures you’d get identical armchairs,” Brian had said. “Are you going to buy twin beds?” The beds would have to wait. For now we had our sleeping bags.

And one of the armchairs. Mine. The other would have to be shipped from the factory. The man assured us it would be delivered within the week. In the meantime we painted, and my darling armchair sat in the middle of the living room, safe from any paint spatters, Brian sitting on it, naked, his peach pink cock aimed straight at the newly painted ceiling.

Arrie and Brian never got to making love, exactly. That’s because right away Arrie started sucking Brian’s cock. His briefs weren’t even all the way down. Brian has a nice cock. This was the first time I’d seen it—big and thick with a nice full helmet, though I couldn’t see much of that because Arrie kept it in her mouth. Arrie was slurping away, and I was snapping pictures, and Arrie was looking at me with those cute brown eyes and the cute button nose, and suddenly I wondered how it would be to suck Arrie’s nose while she was sucking Brian’s cock.

In a flash I closed my lips over Arrie’s nose. I could feel the topside of Brian’s cock rub against my cheek as he continued to fuck Arrie’s mouth. It was so exciting, and I started sucking, too, just as if Arrie’s nose was a sweet little penis. Brian must have thought it was exciting, too, because he started to come. Poor Arrie—my mouth inhaling her nose while Brian’s hot creamy cum was jetting into her mouth—no way for her to breathe. Some of the cum shot all the way through Arrie, like when you swallow milkshake the wrong way, right into my mouth—or maybe it was Arrie’s snot, or probably a mixture of cum and snot. It didn’t matter—it was all deliciously arousing—not at all off-putting. I didn’t swallow it, though—I sputtered it all back out onto Arrie’s face. What a sweet mess she was!

While Arrie lay back on the floor, coughing and gasping, Brian stood over her, his cock drooling the last of its goo onto her. I snatched up the phone and took a couple more pictures.

“Why’d you do that?” Arrie asked me, after she’d recovered, after Brian, the perfect young gentleman, had taken off his briefs and used them to mop some of the splatter from Arrie’s face.

“Look at the pictures and you’ll see,” I told her.

We downloaded them to Arrie’s laptop computer, temporarily on the kitchen counter next to the microwave, and crowded around to watch the slideshow. The photos turned out pretty well, I have to admit—nice clear cocksucking details: Arrie’s pretty eyes, her plump lips, her hollowed cheeks, and Brian’s sleek and handsome stalk. “Yeah, I see what you mean,” Arrie said, when the pictures started cycling around again. “I don’t blame you for sucking my cute little nose. I do look pretty hot, don’t I?”

Brian must have thought so, too, because his cock began to bob up like an eager puppy. “Your turn,” Arrie said to me.

How could I resist? But I played it cool. “Do you dare me?” I asked.

“I dare you,” Arrie said.

Brian’s helmet was so soft to my tongue. I sucked him slowly, carefully, while Arrie took pictures. All the while I sucked him, I expected Arrie to suck my nose, just like I’d sucked hers. Brian took a long time. I imagined the way Arrie’s tongue would feel touching the tip of my nose, licking my upper lip, nuzzling the holes of my nostrils.

“Make him come now,” Arrie said. “Put your finger in his asshole and make him come.”

I moved my hand tentatively to Brian’s bottom. His muscles clenched. I smoothed my hand over the firm flesh, but I didn’t do his asshole. I’d never done that to a boy before. Not until Arrie took my fingers in hers and guided them to the spot. Not until Arrie’s fingers pushed my middle finger in. So hot and tight and smooth in there.

“Finger fuck him,” Arrie said. “Finger fuck his ass until he comes in your mouth.”

I was shy to do it. Arrie made my hand move. Brian’s cock grew in my mouth. Suddenly Brian was coming. His asshole squeezed my finger so tight. His cum filled my mouth so full. I forgot all about Arrie sucking my nose, until it was too late.


When I got back from the bathroom and cleaning myself up, Brian and Arrie were back in our almost bare, peach pink painted living room, almost bare themselves, and they were sitting on my brand-new chair. Actually Brian was sitting on my chair. Arrie was sitting on Brian, straddling him, facing him, fucking him.

Arrie and I had spent a lot of time searching for just the right living room chairs. In the furniture store showrooms, we would run our hands over the fabric of the seats, testing for softness and smoothness and firmness, and when the furniture salesmen were distracted, we’d seat ourselves sans panties and ascertain with our bare bottoms whether the feel was just right. This one was, so we’d ordered two, one for either side of the fireplace, but for some reason Arrie’s hadn’t been delivered, just mine, and now it wasn’t my bare bottom upon it; it was Brian’s gruff ass.

“What are you doing?” I asked, as if it weren’t obvious. “On my chair,” I added, in a smaller voice.

“Duh,” Arrie said, eyeing me over her shoulder. “I didn’t think you’d mind. I share my boyfriend with you. The least you can do is share your chair with us. It’s super comfy,” she added, “perfect for sex.”

I watched them do it for a while. What a pretty picture they made, Arrie going slowly up and down on Brian’s beautiful cock. I couldn’t believe Brian could get it up again—third time in less than an hour. Arrie must have read my thoughts. She said, “He’s going to last forever this time. I’m gonna come so good and hard. And don’t worry ... we won’t get any stuff on your nice comfy chair. I’ll make sure he squirts it all up deep inside me.”

“Yeah, but what about your stuff?” I said, for each time Arrie lifted, I could see some of her seep clinging like dew to the back rim of her cunt. Some of it was almost sure to get on my chair if I didn’t do something.

But what to do? More and more of Arrie’s excitement was oozing out. I knelt down directly behind her and studied the situation. Clearly I couldn’t stuff the creamy stuff back in: with each of Arrie’s downward dips, more moisture squelched out. Why did my sister have to get so wet? Was I that way? To tell the truth, my middle did feel more than a little moist. But I couldn’t worry about that now. I had to save my chair.

And so I did the only thing I could. I gathered Arrie’s gush against my fingertips and herded the slipperiness upward. The little peach pink button of her asshole opened easily. She was tighter than Brian there, and hotter, too, and I could feel the firm push of Brian’s penis in the adjacent sheath. Forgetting about my mission, I rubbed Brian through Arrie’s walls. Wailing, she bottomed out, my finger still all the way in. Immediately, everything went lewdly, intensely, manically wild, like whirlwinds, earthquakes, and volcanic explosions all mixed together. Like whirlwinds, earthquakes, volcanic explosions, and floods!

“Fuck!” Brian said, jabbing the word out.

“Fuck,” I echoed, not really an echo ‘cuz I made my “fuck” long and slow and sweet and lewd. And then, “Fuck!” a harsh bark of a fuck, for smack in the center of my brand-new chair sat a wet spot the size and shape of Texas. Smaller wet spots, like various Hawaiian Islands, stained the mainland’s rim.

I was seething. “How could you?”

“I’m sorry,” Brian said. “I didn’t think I had any more in me.”

“It wasn’t just you,” I told Brian. “Some of that belongs to my slutty sister.”

Arrie pouted. “I think it looks kind of pretty,” she said.

“Yeah, but it’s so obvious what it is. And have you forgotten? Mom and Dad are coming over in a couple of hours for a first look at our new place. And I already told them about the great new chair. We can’t very well hide it in the closet. Now we’re...”

“Fucked,” Arrie said.

I mirrored Arrie’s pout.

Brian said, “What if we ... you know? ... mixed and matched it with some more ... you know?”

Arrie and I looked at Brian.

“You really think you got any more you-know-what in you?” Arrie said.

Brian blushed. “Maybe,” he said. “I’d like to try.”

For the next hour or so we mixed and matched. Brian, with a lot of help from Arrie and me, added a little—maybe Rhode Island and Delaware and part of Maine. Arrie accounted for Indiana, Arkansas, and a couple of the smaller Great Lakes. Like a storm trooper, I came through with scads of states—coast to coast, sea to sea, probably enough wet spot stains to elect a President.

“And you know what the best part is?” I said to Arrie and Brian while they used Arrie’s and my hair dryers on some of the slightly damp patches.

“What?”

“When Arrie’s chair comes, we get to do this all over again.”


Brian skedaddled just in time. A minute or two after he’d left the apartment, Mom and Dad walked through the door. The plan was they’d sneak a quick look at our new place, our fabulous painting job, then take us out to dinner.

“Hi, Mom. Hi, Dad,” I said.

“Ellie. Arrie,” Mom said. “We just saw the cutest boy coming out of the elevator. He looked like Clark Kent Junior. Does he live in your building? Do you know him?”

“We haven’t quite met all the neighbors yet,” Arrie said.

“How do you like the paint job?” I said, pointing to the peach pink walls.

“Pretty,” my mom said, but she was looking at the chair, maybe because it was the only thing in the room besides us. She walked over to it. “And this is the chair. It’s nice. I thought there were supposed to be a pair.”

“There were,” Arrie explained. “But Ellie’s didn’t come yet.”

“I see,” Mom said. “Well, it’s very nice. Distinctive. I really love the pattern. Maybe I just might get one, myself. Don, don’t you think a chair like this would look good in my new sewing room?”

“Um, you can’t,” Arrie said.

“Why on earth not?”

“Um, they’re backordered. Way way backordered. That’s why Ellie’s hasn’t come yet. It might take, like, forever.”

“Well, we can wait,” Mom said. “We’ve waited this long, after all.”

“The thing is, they’re all unique,” I said. “Like snowflakes. No two alike.”

“I like unique,” Mom said. “That way you can tell them apart. Heaven knows I have enough trouble telling you two apart.”

“Like two peas in a pod,” Dad said for the ten millionth time.

“So shall we go now?” I said.

“We haven’t seen the bedrooms yet,” Mom said.

“Um, we didn’t get to paint the bedrooms yet,” Arrie said.

“But we did buy the paint,” I added.

“Just a second,” Dad said. “After that three hour drive, I have to use the bathroom.”

“Ha!” Mom snorted. “I told you to go when we stopped. But no ... Mister I-don’t-need-to. Fine. I’ll just make coffee. Is that the kitchen in there?”

“Yes, but...” It suddenly occurred to me that Arrie’s laptop was sitting on the kitchen counter, the slideshow of Arrie sucking Brian’s cock still going on, repeating endlessly. How could I have been so careless? “Wait, Mom!” But before I could stop her, Mom was on her way into the kitchen. “Wait,” I repeated in a small voice. I looked at Arrie. She looked at me. We were both biting our bottom lips. “Do something,” I mouthed.

Arrie screamed.

Mom and Dad came running. Dad’s fly was still open. So was Mom’s mouth. “Arrie, what is it?” Mom asked.

“Ellie pinched me,” Arrie said.

Everyone looked at me.

I didn’t know what to say. I just stood there.

“Why on earth did you pinch her?” Mom asked me.

“I don’t know,” I said. “It was an accident.”

“I don’t understand,” Mom said.

“I wanted to see if she was dreaming,” I said.

“That’s ridiculous,” Dad said.

I hung my head sheepishly.

“Now, if you don’t mind, I’ll go finish peeing,” Dad said.

“And I’ll get some ice,” Mom said. She turned to go back into the kitchen.

Before she could take two steps, I screamed.

Mom whirled around. “For heaven’s sake,” she said.

“I was just getting even,” Arrie said.

“You girls!” Mom said.

“Can we go out to eat now?” Arrie said.

“We’re really hungry,” I added.

“Famished,” Arrie said.

“We promise not to pinch each other if we go right now,” I said.

“Well, we have to wait for your dad,” Mom said. “I’ll just go and turn out the light in the kitchen.”
