With my dick in my sister’s hand, I had a million ideas of what I’d like to do next. The mischievous smile on her face furthered that. I knew Leah would be down for almost anything. There was one thing that was off the table, full-on sex. She hadn’t been on the pill long enough yet, and neither of us was willing to risk something bad happening.
I was thinking about blowjobs. Probably because she had just been telling me about swallowing my come, and I had a one-track mind when it came to those.
Just the idea of Leah sucking my dick was super exciting. It was still new enough to me that any time it was mentioned, I was rock hard in seconds. I was sure that someday that would change but today wasn’t that day.
“I kind of want to try what you did with Jordyn,” Leah said, her eyes smoldering as she stroked me. That caught me off guard, and blowjobs were forgotten in that instant. “I want to see what it felt like when you came on her pussy.”
“Mmm,” I moaned and smiled, remembering what that felt like, the noises Jordyn made. “I think that’s a great idea.”
“I bet it will feel even better because, unlike Jordyn, my pussy is perfectly smooth.”
“God,” I groaned, and my cock jerked in anticipation, my mind envisioning my cock sliding through my sister’s perfectly smooth slit.
“Oh, you like that, don’t you?” Leah said, her voice changing, breathier and getting hotter.
“Mhmm.” I nodded.
Leah pushed me to the side, so I was sitting sideways on the couch, my legs straight out across the cushions. Once she had me where she wanted me, she started crawling over me, her eyes never leaving me, and she had a dangerous, predatory smile on her face. She bent down and gave my dick a long lick from root to tip before continuing to kiss her way up my stomach and then my chest.
She brought her nose to mine as she kissed me. She lifted enough for her to reach down between us and adjust the position of my cock so that when she sat down on top of me, I was perfectly in line with her delicate folds.
“Oh yeah, that’s fucking nice,” Leah said, her eyes lidded as she slowly rocked along my length. “I can see why Jordyn liked riding your cock.”
“God, you’re so wet, Leah,” I replied, resting my hands on her hips.
“Does it feel better than with Jordyn?” Leah started rocking her hips faster.
“It’s different,” I said, gritting my teeth as I tried to match her movements with my own.
“Really?” Leah looked stunned and almost hurt that I hadn’t told her she felt better than her friend.
“Yeah, Jordyn and I were lying down,” I reminded her. “So, it felt completely different.”
“Then move,” Leah said, and I laughed. It was like she was in some kind of challenge and wanted to do everything better than her friend. She was already climbing off me, not wanting to waste time, so that she could make it so that her pussy feel better than Jordyn’s. “That way I can lie down, and we can do it that way.”
“You sure you don’t want to go to my room or even yours?”
“No way, this is more fun,” Leah replied, like I’d asked her something completely stupid. “Besides, it’s kind of hot that we can just look out the front window while we’re doing this.”
“And people can look in ... that window.”
“Umm...” Leah thought about it for a second, glancing at the window, looking unsure about it for a moment, but that quickly changed because she started giggling. “Well then, we’d better give them a good show.”
“Can we at least close the curtains? Just in case Mom and Dad came home.”
“They aren’t going to come home.” Leah rolled her eyes.
“I know, but...”
“Fine.” Leah rolled her eyes and groaned. “I’ll get it, but I’m not closing the heavy ones.”
“Deal!”
Leah ran over, not an ounce of shame in her game, and closed the white sheer drapes. Not that they did much in terms of privacy, but something was better than nothing. Still, they did defuse the light coming in and blur anyone’s view enough to be somewhat considered private.
“Better?”
“Yeah.” I grinned and patted the couch in front of me.
“Good!” Leah giggled and bounced her way back over to the couch and dove into me. Seeing her move like that did wonderful things for her body. Her tits weren’t huge, but they bounced and shook enticingly, nonetheless. “Give me a kiss.”
I was not one to turn down that kind of request and gave her a soft, but meaningful and passionate kiss.
“Mmm, I love it when you kiss me like that.” Leah licked her lips, her eyes sparkling as she smiled. “Now, give me what you gave Jordyn.”
Leah flipped over, putting her back against me, while lifting her leg up like she was a dog pissing on a fire hydrant, except she was lying down, which made it all that much more funny in the moment.
“What are you doing?” I asked.
“I’m assuming the position!” Leah joked, quoting what I assumed was a movie or show she watched.
“What?”
“You know, assume the position...” She wiggled her legs in the air. When I didn’t do what she expected, she looked over her shoulder, holding her leg up in the air as she did so. “This is when you put your dick between my legs, Lucas.”
“Oh, I know,” I laughed.
“Then do it already!” Leah whined impatiently. “What are you waiting for?”
“Oh, for fucks sake.” I laughed again as my arm reached out and pressed down on her leg, making it fall back down onto the couch. The moment I moved my hand, she tried to lift her leg again, and I had to shove it back down. “Just ... stay right there for a second, okay?”
I took over from there. I snuggled up against the back of my sister; my cock pressed into her ass.
“Ooh!” Leah yelped and then started giggling. “I didn’t know Jordyn was that kind of girl.”
“Leah...” I groaned.
“Sorry, I was just trying to be funny,” Leah said, smiling, but it changed, and she gave me a worried look. “She’s not, though, right?”
“If you keep talking, you’re going to be...” I rocked my hips forward, driving my hard cock right into the crack of her ass, making Leah squeak and flinch, her ass cheeks flexing and threatening to rip my erection clean off.
“That’s an out, not an in!” Leah gasped, her hands reaching behind in an attempt to defend herself from my cock.
“What if I told you Jordyn likes it?”
“She wouldn’t...” Leah paused, thinking about it. “Maybe ... you’d have to go really slow though.”
“Jesus, Leah,” I groaned.
“I’m just saying,” Leah replied, her voice rising in worry, and what sounded like frustration. “I would let you ... you know ... my butt.”
“I wasn’t planning to.” I chuckled. “But that’s good to know.”
“Lucas!”
“Oh, settle down and just let me do this, okay?”
Shockingly, Leah actually listened. She settled down, her body relaxed as she leaned back into me, and I just held her for a second, and then for a minute. I slipped my arm behind her, reaching it under her neck and shoulders. I kissed the back of her neck, and she purred. My other hand ran up her body, starting mid-thigh as my fingers danced along her skin, over the swell of her hip, and fell into the valley that was her waist before I eventually made it under her arm and reached around her chest, palming her breast in my hand.
“Mmm,” Leah moaned softly, her head rubbing against my arm that was under her, holding her.
I kissed the side of her neck, making her crane her head that much further, exposing more of her delectable skin to my lips.
I shifted my hips, pulling myself back so that my hardon slipped down her ass and found the hollow between her legs. As soon as I knew I was pointed where I needed to be, I pushed forward, sliding between Leah’s legs and was instantly welcomed by the slick, warm heat of her slit.
From there, we moved. I started it, but Leah quickly picked up on what I was doing and followed my lead. We fell into a smooth rhythm. Her body pressed back against mine.
I pushed against hers. Leah’s ass wasn’t as big as Jordyn’s, not that Jordyn’s ass was huge or anything, but it was bigger than my sister’s. That meant I could reach further between Leah’s legs and, most importantly, I could rub the head of my erection along her clit, not just bumping into it when I flexed, but maintaining constant contact as I slid my shaft along it. The reactions were immediate and incredible.
“Oh fuck!” Leah gasped as I started thrusting my cock between her legs faster, harder.
Leah’s arm came up, and her hand found the back of my head, pulling it tighter against her neck as she pressed harder against me. Her breaths were coming in faster, harder as we moved together. It was like there was some sort of ... I don’t even know how to describe what it was really, truly like. The best way I can say it is that it was like there was magical fire between us, created when my cock drove through her folds.
“This feels so good,” I said, my voice rough and low.
“Mmm, please don’t stop,” Leah panted.
“I won’t ... ever,” I grunted, thrusting forward against her ass hard.
“It’s like we’re finally doing it,” Leah gasped out. “Like we’re finally fucking.”
“Oh no,” I replied, my hand tightening on Leah’s boob as I pulled her against me as tight as I could, the soft, spongy flesh in my hand threatening to give way under my grip. “It’s going to be so much better when we finally go all the way.”
“I want you so bad!”
Her body started moving faster and faster, my own reacting to her pace, matching it with my own.
“I know, me too!”
“Lucas, I’m going to come soon...” Leah warned, her whimpers and moans getting louder and louder as our bodies danced together. “Come with me, please.”
“I will, I’m so close!”
“Oh, fuck Lucas.”
“Leah, you have to come,” I groaned, feeling the pressure in my balls increasing, pushing towards the point of no return. “Come with me.”
“Lucas!” Leah cried out, her body heaving as she ground herself even harder against me.
“Oh, fuck!” I felt the dam break, and my cock started throbbing, shooting pulse after pulse of my come forward.
“Ooh, ooh, that’s it, come, Lucas, come!” Leah’s fingers tightened into fists in my hair. “Oh, God!”
It was a moment that seemed to last forever and was over in an instant at the same time. I wanted that moment to last forever, and I couldn’t take it anymore. I felt an incredible amount of pleasure and discomfort mixed together. Something was wrong with me, I couldn’t make up my mind. The wires in my brain were getting crossed, arcing across lines they shouldn’t have, and I wanted more.
That’s when we heard the garage door opening and saw headlights turn into the driveway. Thank God I’d insisted we close the sheer drapes, or they would have seen us for sure.
“They’re home! Holy shit, we gotta get up!” I tried to move, but Leah didn’t budge. “Leah, come on.”
“We have a second, it’s okay,” Leah replied, her body still shaking in my arms. She doesn’t sound at all worried that our parents were home and going to walk in and find my come all over her pussy.
“Leah, please,” I pleaded. “If they catch us, they are going to kill us.”
“No, they won’t.”
“Yes, they will!”
We heard the car pulling into the garage.
“Fine, but you need to do that to me again,” Leah said, waiting for me to agree before she moved a muscle.
“Yes, yes, of course!”
“Okay.” Leah rolled off the couch, getting to her feet and wobbling for a second before collecting herself. I thought we were going to die any second, but then Leah started giggling and reached between her legs and ran her fingers along her mound and then put those same fingers in her mouth. “Ooh, yum.”
“What the fuck, Leah!” I growled and jumped up off the couch.
Leah started moving for the stairs and the bathroom we shared, and that left me with a serious dilemma: go to my room and wait for Leah to get out of the shower, or ... hit the hot tub.
Like the addled-brained idiot that I was, I chose the hot tub.
The second I was in the water, I was frantically scrubbing any remnants of what Leah, and I had been doing when my parents got home. The wait for someone to show up dragged on for what felt like forever. After a while, I thought no one was going to come outside. I thought my sister would at a minimum, but she didn’t show up either.
I was just about to get out when the patio door slid open and my parents, with Leah on their heels, walked out onto the deck.
“There you are.” Mom smiled, looking over at me in the water as she set down a stack of towels on the deck railing.
“Yup, here I am,” I replied, and then chuckled weakly. “All by myself...”
“So, I see,” Mom said, a hint of questioning accusation in her tone.
“You two came home early,” I said, trying to change the subject.
“We just had a couple drinks with Lynn and Jake,” Dad replied, slipping into the water and taking his usual seat in the water. The water didn’t quite reach his shoulders like it did mine when I sat down. “We hadn’t caught up with them in a while and figured it might be a good idea, now that Scott and Ellen aren’t here anymore.”
“Really?” Leah questioned and sighed. “I don’t like them.”
“Why not?” Mom asked, sliding in next to Dad, who lifted his arm out of the water to allow our mom to sit next to him.
“I just don’t,” Leah grumbled. “Lynn is always glaring at me and Lucas any time we see them.”
“They are a bit ... different,” Mom agreed. “They don’t see the world the same way we do.”
“You mean that kids aren’t evil?” I joked.
“They don’t think kids are evil.” Dad chuckled.
“Could have fooled me,” Leah chimed in.
“Anyways,” Mom cut in. “It was just drinks. We didn’t try to set up any get-togethers here at the house or anything like that.”
“Good,” Leah harrumphed.
“You really don’t like them, do you?” Dad asked, smirking at Leah’s reaction to the talk about the Peters.
