-ANDY-
It took me a couple hours before I fell asleep. Jessica saw Natalie and I fucking. And she got off on it. Natalie pretended she didn't notice, but the smug look on her face suggested otherwise. I wanted to question her, but she fell asleep before I found the right words to say.
When I finally went to sleep, dreams of having a threeway with both my little sisters haunted me all night. The image wasn't unpleasant. In fact, it was quite the opposite. But where did that path lead? When would enough be enough? I didn't want to hurt anybody, but when I tried to pull out before, all I did was hurt Natalie.
I woke up early the next morning in dire need of coffee. I grabbed an old pair of boxers from my drawers, put them on, and quietly left the bedroom. I shuffled my feet downstairs and into the kitchen to see Jessica at the kitchen counter, sipping coffee and eating cereal. She was wearing an old, baggy t-shirt that went down to her thighs and hid her figure.
Color left her face when she saw me come in. I gave her a small wave and went to the cabinet to grab a coffee flavor. I picked out one of the little coffee cups, grabbed a mug, and went to the Keurig to brew my cup of coffee.
I stared at the machine as it whirred and hummed, trying to avoid an awkward confrontation with Jessica. However, the silence between us only made the situation even more awkward. Fortunately, Jessica cleared the air before I did.
"I'm sorry about last night," Jessica said, softly.
I smirked. "It's fine. I figured you were just curious."
"I wasn't talking about that."
I chuckled and so did she. "It's okay."
"I get really protective with that girl. She's just so fragile," Jessica said.
"Listen, we need to talk about something," I said, lowering my voice. "She's been asking about Dad."
"Fuck."
"I know. We should have prepared for this, but the thought never really crossed my mind."
"I don't know if he's ready. Shit, I don't know if he'll ever be ready."
"For now let's just focus on what we're gonna tell Natalie."
"Okay, but we have to do it together."
"Deal."
I saw Natalie coming down the staircase and I turned around to grab my coffee. The less suspicious Jessica and I looked, the better. Natalie came in and gave the both of us a big smile.
"Good morning, guys!" Natalie said, cheerily. She was wearing a tight tank top with no bra (her breasts were small enough to not really need one) and some booty shorts.
"Morning," Jessica and I grunted.
"What were you guys talking about in here?"
"We were just making up," I said. "You guys want pancakes?"
Natalie gasped. "Yes!"
"Dude, I just had cereal," Jessica groaned.
"So is that a 'yes' or a 'no?'" I asked.
"It's a 'yes,' but I'm gonna bitch about my weight later."
Natalie wrapped her arms around Jessica.
"Shut up, Jess, you have nothing to bitch about," Natalie said, before planting a small kiss on Jessica's cheek.
"That's funny, coming from the ninety-pound twig that can eat anything."
"Oh, I cannot eat anything."
"Very true. Who can forget the haunting scent of 2010's spicy burrito incident?" I said with a smile.
Natalie gasped, ran over to me, and started hitting me in the arm repeatedly, while Jessica just sat there, laughing her ass off.
-NATALIE-
For the rest of the day, all the drama and sexual tension died away and we were siblings again. We ate breakfast, Jessica told us all about college life (but reminded us that it didn't matter, since she dropped out), and we spent the day watching movies together.
All three of us sat on the leather couch in the TV room, with me in the center and both my siblings on either side of me. The room still vaguely smelled like sex, but at least the couch was dry. I was surprised that our sweat and cum hadn't left massive stains on the dark brown leather.
"Can we pause for a second?" Jessica asked. "I have to tinkle."
"Sure," I said. I moved to grab for the remote, but Andy was closer. He paused the film and Jessica got up to go to the restroom. When I heard the door close, I leaned over to Andy.
"There aren't any stains on the couch!" I murmured.
"I know, that's amazing. I don't think we cleaned up at all!"
I giggled and pressed myself against Andy. I kissed him softly, then backed away by only an inch.
"I want you. Right now," I breathed.
"Jess is right over there in the bathroom."
"It's okay, she obviously knows about us."
"She's gonna think that she can't leave us alone for a second without us getting it on."
"What if she joins in?"
"She wouldn't."
"She totally would. She's jealous of us, Andy."
"Never in a million years."
I hopped up and sat in Andy's lap, then leaned in to whisper in his ear.
"When you were away, Jess and I fooled around."
I leaned back to see the gratifying look of surprise on his face. He smirked.
"You little liar."
"I'm not-"
The lock on the bathroom door snapped and Jessica came out. She paused when she saw me in Andy's lap, then rolled her eyes.
"I guess I should get used to that sight," she said.
Jessica plopped herself down on the couch and I rolled myself off of Andy, making sure to graze his crotch with my hand. He started the movie again and shifted his legs to hide his growing erection. That failed, so he tried using his hand. I placed my hand over his, then rubbed it lovingly. I maneuvered my hand so that it was touching his cock through his boxers.
"What are you doing?" he said, with a harsh whisper.
"Shut the fuck up," I whispered back. The surprise in his face reflected my own. I didn't know what I was becoming, but I didn't really care at that point.
My hand snaked its way under his boxers and found his cock (not that it was particularly hard to find). I stroked him slowly and watched his face with pleasure. His mouth was slightly drooped open and his eyes were fixed on the TV, though I'm sure he wasn't paying attention to what was happening on the screen.
His cock pulsed in my hand. I could feel the veins against my fingers and I could feel myself getting wet. I squeezed my quivering legs together and moved closer to him, resting my head on his shoulder. He looked down at me and I gave him an innocent, sweet smile. His cock pulsed again and I knew that was my signal to escalate things.
I slowly moved my head down and into his lap. Andy made a feeble attempt to stop me, but it was no use. I pulled back the waistband of his boxers and revealed his cock, the tip of which was soaked in precum. I licked the tip, then closed my lips over it. I moved my head up and down, swirling him around with my tongue.
"Are you fucking kidding me?!" Jessica cried out. My head shot up and I wiped my mouth. "Right in front of me. Seriously?!"
Jessica started getting up, but I leapt over and grabbed her arm.
"Don't go," I said, softly.
"Just warn me next time."
She stood up and I stood up with her. Before she could go anywhere, I wrapped my arms around her and kissed her hard. After a couple awkward moments, she kissed back. I pushed my tongue into her mouth and our tongues both danced around each other.
I pulled my head away, smiled, and looked down at Andy. His mouth was wide open and his cock was throbbing. Jessica and I looked at each other and giggled. I started pulling Jessica's shirt up, but she stopped me.
"Wait," she said. "I don't know if I can do this."
"We did it last week, remember?" I said.
"That was different. If Andy fucks me... I don't know. It's stupid, but..."
"What?"
"It'll be real."
I smiled at her. "You can watch us, if you want."
She closed her eyes and took a deep breath. Then she opened them.
"No, let's do this."
