Sibling Summer Fun

[Author's note: This story is based on a real account shared with me by a reader. Names and some details have been changed to serve the narrative. In the real account, Sam gets to fuck his cousin, but not his sister. In this story, he gets to fuck them both. Enjoy! (LF)]

Summers have always been fun around my house. It's warm, and there are creeks to swim in, trails to hike, and fun places to explore. The summer of my 18

th

year was especially memorable because that's when I lost my virginity to my cousin and was able to play around with and later fuck my sister.

Chloe, my sister, had turned 19 that spring. I was only a year younger - the same age as our cousin Lisa. Chloe was working a part-time job that summer. I'd just graduated and was taking the summer off. Both of us were pretty inexperienced when it came to sex. Okay, totally inexperienced. Unlike us, Lisa was not a virgin - but I didn't find that out until later.

Our property backs up on a creek - with a great swimming hole just downstream. Chloe and I would often take a swim there in the afternoons. One day, Chloe was working, so I put on a suit and grabbed a towel before walking the short distance along the creek.

It was already quite warm, and the cool water felt great as I waded in. There was no one there, and I was feeling a little adventurous. Sometimes we'd seen people skinny dip at this part of the creek, so I thought - why not? I slipped off my swim trunks and laid them on a rock to dry. I swam into a deeper part of the creek and felt so free. My dick swayed back and forth in the current. I even laid on my back for a bit, closing my eyes and soaking in the sun.

After a while, I decided to get out. As I was emerging from the water, out of the bushes came Chloe - wearing a bikini and holding a towel. I could see the surprise on her face as I came up - her eyes went down to my naked crotch.

"Sam! You're not... um..." she said, stammering.

"Wearing anything," I said. "I know. I didn't expect you, or anyone, to be around."

My suit was too far away to grab so I just stood there, half in and half out of the water.

"I, um, got off early. Do you... do that a lot?" Chloe asked, briefly looking up at me before staring once again at my dick.

"Sometimes," I said, trying to decide what to do here.

Then Chloe chuckled.

"What the fuck!" I said. "What are you laughing at?"

"You," she said, motioning to my cock. "It's kind of small, isn't it?"

I looked down. My dick had been in the cool water for a while and had shrunk smaller than normal.

"You've never seen a dick before?" I asked.

"Maybe," Chloe said. "Online."

"Porn? You've watched porn?"

"Hasn't everyone?" she said, still looking at my limp cock.

"The dicks you see there are already hard - and usually bigger than average," I said. "Why are we even talking about this?" I said. "I should get dressed."

"It's okay," Chloe said. "I didn't mean to make fun of you. It looks nice. I was just surprised by the size, that's all."

"It gets much bigger," I said, feeling less embarrassed and a little bolder.

"How?"

"By seeing naked women."

"Oh!" Chloe said.

"Do you want it to grow?"

Chloe hesitated. "Maybe..."

"Then why don't you take off your suit and we'll see what happens."

"But I'm your sister!"

"And a woman, last time I checked," I said with a smile.

Chloe stood there, her eyes going from my crotch to my eyes and back down. Then she dropped her towel. "Just as an experiment, okay?"

"Sure. Just an experiment."

Chloe reached behind her back and undid a tie. Her white suit top came free, and she lifted it up over her neck.

"Wow!" I said.

I'd never seen a naked girl in person. Her breasts were a good size, not so big that they sagged. I saw her light-colored areola surrounding big nipples - nipples that seemed pretty erect to me.

Speaking of erect - I could feel blood flowing into my dick, warming it, hardening it, making it longer and thicker.

"I've never let anyone see my, um, boobs before," Chloe said, hefting her breasts in her hands.

"They look incredible," I said, unable to take my eyes off those two gorgeous globes.

"You're changing," Chloe said.

"I know," I answered without looking down at myself. "Don't stop now."

Chloe shrugged her shoulders and pulled her bottoms down, stepping out of them. I was now standing in front of my naked sister. The effect on me was instant. Her curly blonde hair fell behind and most of the way down her back. Her waist was narrow and her stomach flat. Further down, I saw a bit of blonde hair on her mound and the lips of her pussy, like a white coffee bean, puffy with a slit down the middle. Her long legs completed the vision - a beauty as I had never seen.

"Wow!" Chloe said, looking at my now very hard and very erect cock.

"See, told you."

"You're much much bigger."

"I know. You did that. You're, um, very pretty."

"You think so?" Chloe said, not attempting to cover herself up.

"Oh yeah. Very sexy. You'd get any boy hard really fast."

"Should we be doing this?" Chloe asked.

"I don't see why not," I said. "We're brother and sister."

"It's not like anything's going to happen," Chloe said.

"Um, sure," I said, my head saying 'no' while my dick said 'yes!'. "Want to swim, since you're here and all?"

Chloe hesitated. "Together? Like this?"

"Why not?"

"Okay," she said, running past me, she dove into the water, her boobs bouncing as she ran. As she dove in, I got a glimpse of her ass. Her cheeks were perfect and round and made me even harder.

"Well," Chloe said, splashing me. "What are you waiting for?"

I followed her into the water and dove in. I came up next to her, closer than before. I could see her breasts floating in the water. I wanted to touch them, and other parts of her.

"I know this is probably wrong," Chloe said, treading water, "but it does feel nice... so freeing without clothes on."

"I know, right?"

The water was clear, and I could see Chloe glancing down under the surface as my dick stood straight out from my body.

"I really didn't mean to make fun of you earlier. Your dick is nice. I like seeing it hard like that."

"Gee, Chloe, thanks."

We swam around for a few minutes, splashing each other. I even managed to dunk her, my hand barely touching one of her boobs in the process. As she went under, she was only inches from my still erect cock.

Nothing else happened, and eventually we got out. I'd softened a bit due to the cool water. Chloe kept looking at me as we dressed but said nothing.

That night, our parents went out. After spending some time at the gym, I showered in the upstairs bathroom that Chloe and I share. I had a towel wrapped around my waist as I came out of the bathroom. Chloe was just walking down the hallway, about to go into her room.

"We've got to stop meeting like this," she said, stopping in the doorway.

"I don't mind," I said, smiling.

"Do you have a sec?" Chloe asked, motioning into her room.

"'Course," I said, walking in with the towel still around my waist.

Chloe sat on her bed. "I've been thinking about what happened earlier today."

"Are you sorry we did that?" I asked.

"No, not at all." Chloe paused for a moment. "I, um, I want to see it again."

"Oh!" I said, dropping the towel.

Chloe stared at my dick, limp, but bigger than when I was in the water.

"This is what it normally looks like," I said, looking down. "Want to see it get hard again?"

Chloe nodded without taking her eyes off my crotch.

"You'll have to take off your clothes again."

This time, Chloe didn't hesitate. She stood, crossed her arms, and lifted her top over her head. She undid the clasp of her white bra, and I saw those incredible breasts again. My dick started hardening immediately.

"More," I said, a little breathless at the beauty of my sister's body.

She pulled down on her shorts and panties, sloughing them off onto the floor. I was only two feet from her and could see her more clearly than earlier. Her pussy hair was soft and fluffy, and a little darker - the color of her eyebrows.

My dick stiffened and stood straight out from my body, pulsing slightly. I even saw a tiny bit of liquid ooze from the tip.

"What's that?" Chloe asked, also staring.

"It means I'm very turned on," I said.

"I like seeing you hard, Sam. I know that's strange, but it makes me feel something... something good."

"I'd like to see more of you too," I said. "Can I see your pussy?"

Chloe's eyebrows shot up. "Um, I guess," she said.

She sat on the bed, pulled up her legs and spread them. Her pussy lips came apart slightly and I saw her vagina - glistening wet with moisture. She had delicate petals surrounding her pussy. A little bead of liquid dripped off a petal and onto the bedspread.

I couldn't help myself. I reached out and started stroking my dick. I was already feeling tingly all over.

"What are you doing?" Chloe asked, watching my hand.

"I'm so fucking turned on by you," I said, "that I can't stop it."

Suddenly, I felt this surge of pleasure erupt up my dick. I knew what was coming but could do nothing to stop it. I pumped and a huge stream of white liquid shot out at Chloe, hitting her in the stomach. A second hit her breasts and a third shot got her legs and knees.

"Oh, fuck!" I grunted, feeling the pleasure and the release.

"Oh!" Chloe cried out in surprise. "You're cumming!"

"Oh yeah... umph... oh fuck!" I groaned as I continue to pump out jizz onto Chloe.

"Wow! That was awesome!" Chloe said. "You got it all over me!"

"I'm sorry," I said, feeling a bit embarrassed.

"Don't be," Chloe said. "I loved it."

With that, she drew a finger across her stomach and put it in her mouth. "Mm, you taste good, brother," she said.

"You... tasted me?"

"Mm hmm," Chloe said, putting another bite of my cum into her mouth. "It tastes sweet."

I couldn't believe this had just happened. We stared at each other for a minute or so. A drop of my cum was about to come off a nipple. Chloe got it with her finger. Before bringing it to her mouth, she lightly squeezed that nipple. I noticed it getting harder.

"We can't tell anyone about this," Chloe said, cleaning herself up with a tissue, after handing me some.

"Of course not. It's our secret," I said.

I left and got changed for bed, but the image of Chloe's naked body, and my cum all over her, would not leave my mind.

The next day, Chloe went off to work right after breakfast. She gave my crotch a glance on her way out of the kitchen. Fortunately, only I noticed. I winked at her as she left.

I went back to the swimming hole and swam naked. No one was there, so I laid on my towel afterwards and stroked my cock, thinking about Chloe's body. I didn't bring myself to an orgasm, though. Something in me hoped for a repeat of the night before.

Chloe was out pretty late. I was laying on my bed playing a game when I heard her come down the hall. Mom and Dad were asleep in another part of the house.

"Hey," I called out.

"Hey," Chloe said, poking her head in my room. "What're you up to?"

"Just playing a game," I said, setting down the phone.

She came in and sat next to me on my bed, glancing down at the phone. It felt thrilling to have my own sister in my room after what had happened between us. The forbidden was feeling very tempting.

"Were you okay with last night?" Chloe said, a little sheepishly. "Did you feel funny afterwards?"

"It felt great to me," I said truthfully.

"You really came a lot," she said, looking down at my shorts, which were already starting to tent up. "Are you getting hard now?"

"Uh huh," I said. "Want to strip and watch me cum for you again?"

"No," Chloe said.

I must have looked crestfallen, because she put a hand on my thigh. "This time, I want to do it."

"Oh!" I said, suddenly more excited. "You want to touch me?"

"Can I?" she said. "I've sort of became obsessed with your cock."

"You sure can!" I said.

I took her hand and placed it on my bulging shorts. She pressed down slightly, then squeezed.

"Hm," I moaned.

"It does feel hard."

"Just wait," I said. "Before we do anymore, why don't you close the door and take off your clothes."

Chloe got up and shut the door quietly. She came back and stood only inches from me. She very slowly took off her top, throwing it across my bed. She ran her hands along her boobs, then reached back to undo her bra. I wanted to kiss those lucious breasts so badly!

She shimmied out of her shorts. Her pink panties clung to her slightly hairy mound - a large wet spot traveling up from her pussy.

"You're wet!" I said, looking at her crotch.

"I am," she said as she pulled off her panties.

That got my cock really going. I absentmindedly started stroking myself.

"It's my turn, remember?" Chloe said, standing over me.

"Oh yeah," I said. "I forgot."

I stood up and my chest nearly touched her nipples. I pulled off my shirt and tossed it on the bed too. Then I bent down to take off my shorts and boxers. When I stood back up, my hard cock grazed her stomach.

"Fuck!" she said, looking down at me.

"Go head and touch it," I said. "But I'll warn you, I'm already close thanks to your little strip show there."

Chloe laughed quietly. "Glad I could help."

She gingerly reached one of her delicate hands and grasped my rod. It jumped in excitement.

"Did I do something wrong?" she asked.

"Oh no," I answered. "That feels amazing. Now grip me and twist your hand as you move up and down - shit - like that!"

I watched as she stroked me. It was so unreal. Never in a million years would I have guessed that my own sister would be squeezing my dick.

"Mm... oh... fuck!" I started moaning. "Harder. Squeeze harder."

"It feels really amazing, Sam," Chloe said. "Your skin is so soft and your dick so thick and hard."

She used her other hand to gently caress my balls then did a two-handed stroking.

"Oh!" I gasped. "I... oh, I don't think I can last much longer."

"Go ahead and cum on me, Sam. Go ahead!"

A surge of pleasure erupted from me as streams of cum shot from my dick. The white sticky liquid got all over Chloe's fingers and her stomach and ran down over her pussy hair. I closed my eyes as rope after rope of jizz spurted out. The feeling of her fingers on me made the orgasm more intense than I'd ever experienced by myself.

After I was done, Chloe licked the cum off her fingers and stomach.

"I like how it tastes," she said. "I like you cumming on me."

"Wow!" I said. "I like it too. I just can't believe we're doing this!"

"I know," she said. "Me either."

She handed me a tissue and we sat on the bed, side by side and totally naked. I wanted so much to touch her body - to make her feel things too.

"Sam?" she asked finally.

"Hmm?"

"Have you ever been with a girl?"

I looked at her sideways but chose not to lie. "No," I said. "You're the first girl that's ever seen me naked - ever touched me like that."

"I haven't either," Chloe said. "I'm still a virgin too."

I paused for a moment. "Have you ever cum, um, made yourself cum?"

She looked into my eyes. "I've tried some... but no."

She looked down as if she was ashamed. I lifted her chin to look at me.

"There's nothing to be ashamed of, Chloe."

She gathered her clothes, got dressed, and snuck out of my room. That night I dreamed I went all the way with my sister. What a dream!

We'd been nude with each other, and she'd touched my dick and made me cum. But I hadn't been able to touch her at all. That beautiful body was still a mystery to me.

A couple nights later, our parents were out for the evening - to a bowling tournament believe it or not. I laid on my bed in anticipation of what games Chloe might want to play. She came into my room wearing only a robe. She strutted around, pulling the robe open to reveal her nude body, then closing it back up. She even bent over and showed me her ass as the robe flapped up. I stroked my dick and pulled it out of my shorts.

"I'm really horny," Chloe said, letting the robe drop to the ground.

I saw a glistening of liquid running down her inner thighs - her pussy juice.

"What do you want to do about that?" I asked, hoping for more contact.

"I want you to stand up and come here," she said.

I obeyed, my cock a tent pole as I stepped towards her. She grabbed my dick and stroked it up and down. It felt great. Then she did something unexpected, pulling the head of my cock so it went down the slit of her pussy.

"Oh!" I cried as I nearly came.

"Did that feel good, brother?" Chloe said, seductively.

"Shit, yeah!" I said.

"Good," Chloe said, running my dick across her slit again.

The warmth and slipperiness of her juices was amazing. I was feeling very aroused.

"Don't cum yet, Sam," Chloe said, letting go.

"Did I go too far?" I asked.

"Oh no," she said. "I want you to lay on top of me."

"Do you want to...?"

"No, Sam. I don't want to fuck you. I want you to rub your dick across my pussy - but don't come inside me, okay?"

I was totally game for this escalation. I was finally going to get to touch my sister's body.

Chloe climbed up on the bed and lay on her back. Her nipples stood straight up in the air and looked so inviting.

I got up after her and got on top. My chest pressed in on her boobs and my face was only an inch or so from hers. I wanted so much to kiss her and feel her tongue in my mouth.

"Just rub me, nothing else, okay?" she asked.

"If you say so," I said.

I positioned myself so that my cock rode up between her lips. To say it felt amazing would be an understatement. This was as close to fucking my sister as I'd probably get. My dick slipped easily up and down.

"Oh," Chloe moaned.

I noticed that her hips were moving up and down along with my dick. Her breathing got heavier.

"Oh, ah, oh," she began moaning.

It was all I could take. My dick stiffened and shot out its load, all the way to her face and on her lips.

"Fuck! I'm cumming!" I shouted as pleasure filled my dick and my body.

I shot out my load and Chloe held me as I came. She continued to move up and down but stopped moaning.

"Wow!" I said, rolling off. "Was that okay?"

"It was," Chloe said, but I noticed a little reserve in her voice and wondered if I'd gone too far.

I expected that to be that. I nearly fucked my sister, and I guessed that was too much for her. Boy, was I wrong!

The next night our folks went back to the tournament. This time, Chloe invited me to her room. I so much wanted to kiss her, to touch her boobs, to caress her pussy and put my dick into her. But I dared not hope.

"Take off your clothes," Chloe said, stripping.

"You don't have to ask me twice," I said.

I got naked and watched as Chloe undid her bra and let her wonderful breasts bounce. Her nipples were erect and her pussy already wet as she pulled off her panties.

She walked up to me and planted just the briefest of kisses on my lips. My dick jumped in response. Chloe noticed and grabbed my rod, stroking me.

"Do I turn you on, Sam?" she said, playfully.

"You know you do. You drive me crazy!"

"Ha ha. Good!"

She rubbed my dick along her slit again, covering the head with slick juice.

"I want to be on top this time," she said.

"Sounds wonderful," I said.

"Lay down and let crawl on top of you," Chloe said.

I got up on her bed. It smelled like her - a sweet perfume. I looked around at her decorations and posters. I was in my sister's room - naked - with her about to straddle my dick. I nearly came at the thought.

"You can't come inside, remember?" Chloe said as she got up on the bed.

"I won't, I promise," I said, secretly hoping she'd change her mind.

Chloe laid down on top of me, and I felt her move my cock so that it was right between her lips. If I just pulled back slightly, I felt like I could enter her. But I didn't. I laid still and let her move on me.
