At her words, Carly tensed up, and her groans abruptly stopped. I grunted before shooting cum on my sister’s belly and tits. Karina grinned and offered me her two fingers to sucking on. As Carly cooed below me, I bit my sister’s pussy off her fingers.
“That’s really fucking hot,” Karina sighed as my tongue slithered between her fingers for the last tastes of pussy. “I want to do this again.”
Carly was already half asleep. “Yes. Sleep now. Fuck later,” she mumbled.
Karina stood and kissed me. “See you in the morning.”
I grabbed my clothes and headed through the bathroom to my room. I never bothered to close the doors behind me. There probably wasn’t much of a point anymore, other than for appearances sake.
I slept soundly. No vivid dreams, no interruptions. My phone vibrated with an email and then I was hearing the girls in the bathroom. The door was still open. I heard the water running in the shower. I pulled myself out of bed, still nude from the night before, and walked to the doorway. Carly was standing at the sink brushing her teeth, clad in a matching black bra and panties. Karina was in the shower. I just nodded and went to pee. I heard the water in the shower stop and the click of the door opening.
“I guess we didn’t kill him after all.” Karina laughed as she stepped out. I watched the drops of water running down her perfect tits and dripping from her pussy.
“Not for lack of trying,” I deadpanned, flushing the toilet. I turned to face them, cock starting to show signs of life somehow. “But I’m not complaining.”
“We’ve got to be careful,” Karina said softly. “We got a little loud and reckless last night.”
“And our entire room reeks of pussy and cum. I already put the sheets in the wash, lit a few candles, and opened the window,” Carly added, pausing as she took a swig of mouthwash. “I hope mom doesn’t go in there. You might need to go finish that load for us while you’re home in case mom gets home early.”
“Sure,” I agreed. “I’ll be glad to finish a load for you.” I poked Carly in the side with my erection.
Carly rolled her eyes and Karina giggled.
“Don’t encourage him. I’ll jack him off on your clean underwear and you’ll have to change again,” Karina said, grasping my cock and pointing it teasingly at my sister. She squealed and ran into their room. Karina turned to face me but didn’t release her grip on my dick.
“Seriously. That was fun last night but we can’t do that every day or we’re going to get busted for sure,” she said, slowly stroking my erection.
“I understand,” I said, watching her hands work back and forth along my stiff prick.
“Hurry up, we’ll be late.” Carly re-emerged fully dressed in a denim skirt and pink blouse. “Suck his dick and let’s get going.”
“Bossy,” Karina stated. She dropped to her knees and started sucking my dick with a purpose. One hand cradled my balls and the other went between her legs to finger herself. Carly leaned against the sink and watched, cupping her big tits in her small hands.
“That’s fucking hot girl, you on her knees, sucking my brother’s big dick. He should cum all over your face,” Carly teased herself and me. If she was trying to make me cum faster, it was working.
Karina looked up at me with a demure smile. “Do you want to cum on my face Trevor?”
I grunted a reply. Karina took me as far in her mouth as she could, then wrapped her hand around my cock and jacked me off fast. She licked the tip of my dick a few times and I came again, hitting her in the cheek with the first shot, then she directed the spray in her open mouth. I stumbled back against the wall as she stood up. Carly kissed her and they made a show of swirling my seed between their mouths. Damn that was hot!
“Mmmm. Fluoride, mint and semen, what a combination,” Carly mused, grabbing a towel to wipe her lips clean after swallowing. She delicately wiped seminal fluid from Karina’s face.
The girls disappeared into their room but left the door open. I stumbled back into mine and went about my morning. I had work emails to handle and more project work to do. I looked up a few times, noticed the open bathroom door in my room and smiled.
The girls weren’t home until after dinner that night. I was blasting zombies with my online crew when Karina poked her head around the open bathroom door.
“Hey there,” she beamed. I paused my screen.
“Hey you,” I replied, enthralled by her smile.
“Just checking on you, we missed dinner and you were already shut up in here when we got home. Everything good?” Her shirt was tight across her chest. I struggled not to stare.
“Yeah. Did some work and now I’m just playing a game with some friends.” I tried hard to keep my gaze at her blue eyes as she sat on the edge of my bed.
“Ok, we had a long day and are probably going to sleep soon.” She leaned back on her elbows, making her boobs jut out more prominently. She grinned as I noticed.
“Yeah, me too,” I said, eyes focused on her rack.
“Are … are you ok with all this? It’s been a crazy couple of days.” She grasped my hand as she spoke.
“That’s an understatement,” I quipped, “I was a little weirded out at first, but yeah, I think I’m good.”
Karina stood up, leaned over me, and kissed me full on the lips. Soft and gentle. She pulled away.
“See you in the morning Trevor.” She winked at me and disappeared through the bathroom. I resumed my game with a smile.
A couple hours later I logged off and climbed into bed. Not long after I heard the shower start up. There were no giggles or moans coming from the bathroom. I assumed one of them was just showering like a normal person.
I think we all needed a normal day. Karina was right, it had been a wild couple of days. I never imagined that I would have had ever seen one of them nude, much less do any of the sexual things we had done.
I woke up the next morning with a raging hard on. No surprise, I guess. I could see the light on in the bathroom. I heard Carly’s voice. I stood in the doorway for a moment. She was standing at the mirror, wrapped in a towel and brushing her hair.
“Hey sleepyhead,” she smirked. “I thought maybe you didn’t want to play around anymore.”
“I was tired.” I defended myself weakly as I lifted the toilet lid.
“Nice boner,” Karina said as she walked in and watched, fully dressed in some tight jeans and a t-shirt. “I wondered if you’d be up before we left.”
“I think that thing is always up,” Carly said. I flushed and started to put my dick back in my boxers when Carly swatted my hand away.
“Leave him out. I like to see it get hard.” And with that, she dropped the towel and stood in front of me naked, eyes laser-focused on my cock. Karina giggled. I stared at my sister’s tits and pussy. My dick got harder and harder.
“I guess you’re going to suck it before we go this time?” Karina asked.
“Probably, although we might be late for school again.” Carly stepped closer and stroked my dick a few times. I palmed her tits and rubbed her nipples with my thumbs. “What do you think, brother?”
“I think you should do it. I won’t complain if you don’t though,” I said, busying myself with her boobs and exhaling as Carly continued to give me a hand job.
“We need to leave in 15 minutes and you’re still naked,” Karina said.
Carly kissed my cheek and let go of my throbbing member. “To be continued,” she whispered.
Karina gave me a kiss as well, this one on the lips. She lingered a moment, ran her hand down my chest, and whispered, “Save that for later.”
And in a moment, they were gone. I dressed, ate and got down to work. Dad’s boss had sent me a formal contract to complete the job as discussed, plus a retainer offer for me to do some training and maintenance on the program.
I was floored. The money in this deal was big, especially for someone with no real expenses. I had been preparing to move out this summer, but now I could afford a down payment on a house if I wanted. I spent some time looking at home listings as well.
There were some phone calls and arrangements for me to make, and that occupied the rest of my day. I needed to go meet with the company IT guys in the morning, so I took my new shirt and some slacks to the dry cleaners. The day sped by.
Mom was home early. Dad had apparently told her already, and she was excited. She suggested I get a haircut to make a good impression. Dad had subtly hinted at that at one point too. I might just be a computer techie, but this was a very buttoned-up, corporate environment, so I went back out.
Karina and Carly got home while I was out. Dad came home early, and I walked into a full house. Dad gave me a big bear hug. Karina gave me a big hug and kissed my cheek lightly. Carly followed suit, and I thought I saw mom and dad exchange an odd glance.
I was instructed to put on some nice clothes, as I was being taken out for dinner.
“Don’t worry mom, we’ll make sure he’s dressed nice,” Carly said, grabbing Karina by the arm and marching past me to my bedroom. I shrugged and followed.
When I opened the door, Carly dragged me inside and kissed me while Karina went fumbling through my disorganized mess of a closet.
“God I’m horny. And now dinner with our parents? I’m going to burst,” she said, breathless as our lips separated.
“Here,” Karina handed me some jeans and a polo I had forgotten about. “And hurry up. We don’t need to make Harold and Vivian suspicious,” she said with a wink. She dragged my sister off me and left me to change. My dick was getting hard. It would be uncomfortable trapped under the thick denim all evening. On the other hand, an erection would be less obvious that way as well. Damn she was as smart as she was sexy.
