I'd just had the most wonderful experience of my life. Normally shy and reserved, I'd witnessed my own sister jerk off my brother while we were watching a sexy movie. When I confronted them, they introduced me to sibling sex. I gave them my virginity and they brought me to mind-blowing orgasms.

The next day I was still on a high and couldn't wait to learn new things from them.

But something was bothering me. I'd seen first-hand the changes that my Aunt Delia's presence had had on my family. Now, I knew that Kurt and Connie, my older twin siblings, had fucked Delia and each other. But I'd also noticed changes in my mom's behavior.

She'd started dressing more risqué - short skirts, tight-fitting tops, etc. I'd noticed a new freeness about her, even a sensuousness I'd never seen before. It got me to wondering what experiences she might have had with her sister. I knew they'd never been close, but something had changed dramatically.

I decided that I'd talk to her - not confront her like I did with Kurt and Connie. Maybe I'd even confess what I'd done with her other kids.

"Oh, hey, Julia," Aunt Delia said as I passed her in the hall. "I was hoping you and I could grab coffee or a beer by the pool sometime. I haven't had much chance to get to know you since I've been here."

Delia (as she likes to be called) was living with us while her mansion in the country was being renovated.

"Um, sure, Delia," I said, stopping on my way to Mom's room.

"It's a date then!" Delia said, touching my arm.

There was something in her look and the way she touched me. For some reason my pussy kind of got a little excited. She is a beauty, that's for sure. Though she's older than my mom, she looks like a model. Brown wavy hair, large boobs, slender arms and a totally flat stomach. And her eyes - they make you want to sink into those blues.

Maybe I got excited because I knew she'd slept with my sister. Connie was my first lesbian experience, and I was looking forward to more. Perhaps Delia would seduce me too?

"Tomorrow afternoon, then," she said, beginning to move. "By the pool? I hear the others are going out. We'll have the place to ourselves. It'll be fun!"

"Sure," I said.

I headed upstairs and down the long hall to my mom's room. It's more of a suite, really. It has a living room with couches and chairs, a small kitchen, and the bedroom with a large king-size bed and a great view. Mom and I used to have tea with Connie up there every week.

Mom's suite is pretty separate from the rest of the bedrooms. She has a double French door as a grand entrance. One of the doors was just slightly ajar. And from inside, I could hear something. I was pretty sure Connie was in her room, and I'd just seen Delia.

I got closer and heard the unmistakable sounds of two people having sex.

"Ooh, so slippery," I heard a male voice say. "I just slide right in."

"That's 'cause you make me so wet!" A woman said. "Oh, right there. Ooh - fuck me. Yeah!"

I put my ear to the crack and heard the rustling of covers and slurping sounds, along with moans and heavy breathing.

Did Mom have a guy over to fuck? This would have been totally out of character for her. Since a horrible incident with my dad many years ago, my mom had not been on a date and avoided family contact. That had changed with Delia - maybe more than I knew!

I took a chance and pushed the door open, just a little. There was no one in the living room. The sounds were coming from the bedroom. The double doors to that part of the suite were wide open.

I tip-toed across the room. Spying was not something I normally did, but lately this family had been anything but normal.

"Mm, you feel so good inside me," Mom said.

"You're so tight," the man said.

"Does it make your cock tingle?" Mom said.

"Fuck yeah!" the man said.

I crept over to the door, hoping to catch a glimpse of who was fucking my mother. The voice was familiar, that was for sure. I peeked around the door and nearly cried out. Mom was on her bed, lying on her back. Between her legs, his big cock moving in and out of her pussy, was my brother Kurt!

I managed to keep myself from falling over and crouched down to steady myself. The sight in front of me was shocking and very sensual. I knew what Kurt looked like nude - and with an erection. His big cock had taken my virginity only the day before. Just thinking about him sliding in and out of me got me aroused.

But I had never seen my mother naked. She held her legs wide open, her knees suspended in the air. Her eyes were fixed on Kurt's face. She was breathing hard and letting out little grunts of "Oh" with every breath. Her large breasts and big areola went up and down with each thrust of Kurt's cock. I watched it go in and out. In another shocker, Mom was waxed - her mound smeared with clear pussy juice that dripped off Kurt's dick.

"You... fuck so... good," Mom said.

I couldn't believe what I was seeing and hearing! My reserved, closed off mother, had opened her legs to her son's cock and was talking so... dirty!

"I love fucking your pussy, Mom," Kurt said. "You're so wet!"

"You... turn me on... so much!" Mom said.

She looked down at Kurt's cock sliding in and out of her cunt. "Keep going. Don't... stop!"

This was too much for me. I stuck my hand down my panties and felt my wet pussy. I rubbed my slit and clit and was getting very aroused.

Kurt leaned down and took one of Mom's nipples in his mouth.

"Oh!" Mom moaned. "Faster!"

Kurt sped up, his dick flying in and out of her.

"Yeah... I'm... don't stop... oh, I'm cumming, I'm cumming... I'm AHHHHH!"

Her pelvis shot up in the air and she cried out "Ah! Ah! Ah!"

"Oh, fuck!" Kurt cried out. "I'm... shit... cumming too!"

Kurt pushed in deep, and I could tell he was shooting off one of his big loads of cum right into Mom's pussy. She kept cumming as Kurt kept thrusting.

Now I was nearly cumming myself. The sounds of their pleasure and the smell of sex filled the room.

"Mmph... mmph," I whimpered as quietly as I could.

I was going over the edge. I blanked out for a second, holding onto the doorframe to support me. I closed my eyes as my body was flooded with pleasure. I felt like I had to pee as the orgasm overtook me. I felt liquid squirting out of my pussy. It felt incredible!

When I looked back up, I saw two pair of eyes staring at me. Kurt continued to slowly push in and out of Mom's pussy. Mom still held her legs and looked like she was just coming out of a dream. As it appeared to register who she was looking at, she smiled.

"Julia!" she said. "Oh my. This is embarrassing!"

Kurt smiled as well and withdrew his now softening cock. White liquid dribbled from the end of his dick. He sat back on his legs and Mom closed hers, bringing herself to a sitting position and cupping her breasts in her hands.

"Looks like you made yourself right at home," Kurt said, glancing down at the floor beneath my feet.

I looked down and saw a small puddle of liquid. Embarrassed, I withdrew my hand from my panties.

"I didn't know you could squirt, Julia!" Kurt said, looking back up at me.

"I, uh, didn't even know what that was," I said.

"Come in sweetie," Mom said. "We sure need to talk."

I stood and stepped through the doorway.

"You don't have to hide yourself, Mom," I said. "It's okay."

"Oh," Mom said, removing her hands from cupping her breasts.

"They're beautiful. And so big," I said.

Mom glanced down at her chest. "Well, I never thought you'd see them this way. Or any of me!"

"She is gorgeous, isn't she?" Kurt said.

I sat on the edge of the bed, only inches from my naked family. I couldn't help but look at Mom's pussy, on display right in front of me. A small amount of white liquid seeped from her pussy, and her mound shined with her juices.

"I, um, don't know what to say, Julia," Mom said. "You aren't as shocked as I'd imagined."

"Tell her why, Julia," Kurt said.

I looked at Kurt, then back at Mom. "Kurt and Connie and I had a conversation yesterday about their relationship. I said I'd seen some new weird stuff going on around here after Delia arrived. They told me how wonderful it was having sex with her, and each other.

"And?" Mom said.

"And I ended up letting them take my virginity. Seeing Kurt fuck you like that brought back memories of him cumming inside me and, well, I got really turned on."

"Wow!" Mom said. "That's a lot to take in."

"So is the fact that your intimate with each other too," I said. He didn't say anything about it."

Mom looked at Kurt. "Not his story to tell, I guess."

"But this isn't the first time you two..." I said.

Mom shook her head. "No, we've been enjoying each other every chance we get. With Connie too."

"I kind of figured that," I said. "Man, Kurt - your cock is sure getting a lot of action between me, Mom, Connie... and I guess Delia too!"

"It's true," Kurt said. "Best time I've ever had. And so far, my guy is keeping up!"

As he said this, he looked down at his now soft dick, still dribbling little bits of white cum.

"So..." Mom said. "What would you like to do now? I'm sure this isn't why you came up to my room."

"I was actually going to talk to you about what happened to me," I said, tentatively reaching out and placing my hand on Mom's thigh.

"You were?" she said.

I nodded. "I've seen you acting and dressing very differently. Since finding about that Kurt and Connie were intimate - I wondered if maybe you were too."

"Well, now you know," Mom said, putting her hand on top of mine.

"I know this is going to sound strange," I said, having a hard time believing I was going to suggest this, "but... Connie did something to me yesterday that I've been wanting to try. Two things actually."

"Do tell!" Mom said, caressing my hand and sending tingles into my pussy.

"After Kurt came inside me," I said, "Connie asked if she could clean up Kurt's cum on my pussy. It felt so good that I came a third time."

Mom raised her eyebrows. "And the other?" she said.

I looked at Kurt's limp dick. "The other was a way to get Kurt hard by sucking his cock."

"And what did you have in mind?" Mom asked.

"Um, what if I licked your pussy, Mom and you sucked Kurt's dick so he could fuck me with you right here."

"Wow!" Mom said. "I never would have imagined being propositioned by my own daughter. But I love it!"

Mom leaned over and tilted her head. I did the same and we kissed. I immediately felt her tongue ask permission to enter my mouth. I opened and our two tongues swirled around each other. My pussy was getting very wet.

Mom reached out a hand and fondled my breasts, tweaking my nipples. I felt Kurt's hand on my pussy, rubbing my slit over my panties.

"You're so wet!" Kurt said.

"I'm pretty wet too," Mom said as we broke off.

I looked down and noticed clear liquid along with Kurt's cum, oozing from her opening. I gently pushed her down, so she'd lay on her back. I stood and took off my shirt, skirt, and panties.

"You are an absolutely beautiful girl," Mom said. "I can't wait to get to know you better!"

I got back up on the bed, leaned down, and kissed one of mom's nipples.

"Ooh!" she said. "Oh wow!"

I licked around her large areola and sucked in on a nipple.

"Mm!" Mom moaned.

Kurt came around and positioned his dick near her mouth. She reached over, took his shaft in her hand and popped it into her mouth. The whole thing fit, which surprised me.

"Oh, yeah," Kurt sighed.

As I suckled Mom's other tit, I watched her suck in her mouth and pull Kurt's cock out, repeatedly sucking and pulling. It was growing right before my eyes.

Mom's pelvis began a waving motion up and down. I moved between her legs. I was about to do something unimaginable only 24 hours ago - get my first taste of cum and lick it off my own mother's pussy lips!

I moved up, kissing her thighs. She started moaning, her mouth full of Kurt's growing erection.

I could smell her scent, mixed with the smell of Kurt's cum. It was intoxicating. Liquid and cum were dripping down her thighs as she got wetter and wetter. I flicked out my tongue to catch some of the cum as it oozed out of her.

"Ah!" Mom moaned.

Kurt's cum, mixed with Mom's juices, tasted watery and sweet - not at all what I'd imagined. I liked it, so I started slurping it up. Mom's hips moved up and down more quickly. Since most of it was coming from her vagina, I stuck my tongue into her opening and got a mouthful of white cream.

"Oh!" Mom cried.

I kept licking, finding her clit and sucking in on the little erect nodule. She started moving her hips up and down faster and faster. Her breaths were coming in ragged bursts.

"Oh... oh... oh!" she moaned, coming off Kurt's now hard cock.

Mom's hand continued to jerk Kurt off. She tilted up her head so she could watch me eat her out, her other hand holding my head.

"Oh, Julia!" she moaned. "You... are... I'm... oh... oh!... OHHHHH!"

Suddenly her hips shot up in the air and started spasming. I felt juice flow from her pussy and into my mouth.

"Ah! Ah! Ah!" she cried as she came. I'd just given my mother a lesbian orgasm!

As she calmed, she grabbed me, pulled me up, and we kissed - passionately, deeply.

"Oh, I can't believe what you just did!" she said as we broke off.

"And look what you did to Kurt!" I said, looking at him gripping a now raging erection. "And I know where I want him to put it!"

"That sounds great to me!" Kurt said. "Do you want to ride me?"

"Ride you?" I asked.

"Yeah, sit on my dick. Connie says it feels really good."

This must have been one of the new things Connie and Kurt had wanted to teach me. "I'm game," I said, "As long as I get your dick inside me. I'm itching to cum again!"

"Now this I've got to see!" Mom said, sitting up and rubbing her pussy.

Kurt laid down on his back. Mom held his dick in her hand.

"Just straddle him and face me," she said.

I put my leg over Kurt's waist and started getting the idea. I lowered myself while Mom positioned him right at my opening. I was so wet that I literally dripped juice on the mushroom-shaped head of his cock.

I kept crouching down until I could feel his dick begin to open up my labia. I felt that now familiar feeling of pleasure as I lowered further. The pleasure pressure increased as more of him went inside. Finally, I was sitting on Kurt's pelvis - his cock fully in me.

"Now just lift up with your legs a little and settle back down," Mom said. "It feels amazing!"

I did as Mom instructed. As I lifted, I felt tingly feelings in my pussy. I watched Kurt emerge - slippery and shiny with my juice. I lowered myself back down to more tingles.

"Oh!" I exclaimed.

"Now you've got the idea," Mom said.

I lifted up and sat back down on Kurt's dick. The faster I got, the better it felt. Mom came up and kissed me while I fucked him.

"Now sit down and let Kurt fuck you!" Mom said.

As I settled down, Kurt moved his pelvis up and down, sending his cock even deeper inside me. Mom moved over and straddled Kurt's head, positioning her pussy right over his mouth.

As Kurt licked Mom's pussy and fucked mine, Mom and I kissed and fondled each other's breasts. Hers felt so full and large. I leaned over and took a nipple into my mouth.

I started feeling myself building to an orgasm. I started moving up and down again. I wanted to be in control. I pulled way up and then plunged Kurt back into me slowly. I repeated this over and over - each time I got closer and closer.

"Oh!" Mom was moaning, watching me fuck my brother.

At the sight of Kurt's mouth making Mom cum again - I went over the edge. I put myself down so my clit could rub against Kurt's pelvis while his dick was buried all the way inside me.

"Ah! Ah! Ah!" I cried out in ecstasy.

I felt Kurt's dick expand and knew he was shooting rich, white cum into my pussy. It made me cum even harder. I bucked and spasmed as pleasure erupted inside me over and over.

As I came down from the high of my orgasm, I noticed that Kurt was still inside me. By sitting on him, he didn't slip out like before.

"I love the feeling of you still in my pussy," I said.

"I'm still spurting cum into you too," Kurt said as Mom got off his face.

I rode him a bit longer, trying to squeeze all the cum from his dick. Mom came over and we kissed and tongued each other. Eventually, I got off and let Kurt slip from inside me.

"Maybe I can clean you up this time," I said to Kurt.

"Suck my dick?" he said. "Absolutely!"

"Why don't you join me, Mom," I said.

Together we licked and sucked. She showed me what to do and it felt great.

"Want to clean me up like Connie did?" I asked.

"So much!" Mom said.

She started licking all the white cream off my pussy - and got me so turned on that I came again.

We lay there, exhausted but extremely satisfied.

"I can't believe my family is so together now," Mom said, stroking my boobs with one hand while stroking Kurt's dick with the other. "And it's all thanks to Delia."

"Speaking of," I said. "She and I have a date tomorrow when you guys go out."

"Seriously?" Mom said. "I hope you have fun."

"Oh, I plan on it!" I said.

The rest of that day passed slowly. My mind was trying to adjust to a new normal in my family. Instead of just being related to each other, we were sharing our bodies with each other - giving ourselves to licking, fucking, kissing, and fondling. It was bizarre, yet wonderful at the same time.

The person at the heart of it now wanted to have a "date" with me. What Delia had in mind, I had no idea, but hoped she might want to be intimate with me as well.

The next day, Kurt had to go to work, and Mom and Connie went shopping. That left me alone with Delia. As promised, I met her out at the pool in the warm afternoon sun. I wore a bikini, one that covered my boobs but left plenty of cleavage, and a bottom with a little triangle to hide my bush, but a slight string in the back, exposing my butt cheeks.

I stepped out onto the deck and noticed Delia was already sunning herself on one of our chaise lounges.

"Grab a beer from the fridge," she said, holding up a cold bottle.

I opened the fridge and pulled out a pilsner. Mom let us drink at home, even though I was underage.

As I approached her, Delia patted the chaise next to her. I sat and noticed Delia's swimsuit. It was white, tiny, and a bit see-through. Her dark areola showed through the fabric and her tits poked out a bit. The tiny triangle of her bottoms would not have covered her bush - which I assumed was shaved or waxed.

I knew how beautiful Delia was, but in this suit - oh my! Her large breasts were like two huge globes, sticking out on all sides. Her slender waist and flat stomach - and long smooth legs were captivating.

"Cute suit, Julia," Delia said. "Looks good on your petite figure."

"Thank you!" I said. "I like yours too."

"Do you think I show through too much?" she said, adjusting the top and brushing her fingers along her nipples."

"Uh, no. It's fine. Looks good," I said.

"Good," Delia said. "As long as you like it."

I sat back and opened the beer, taking a swig and setting it down on the table next to me. Delia took several drinks before finishing her bottle.

"Time for another," she said, getting up.

As she walked over to the fridge, I noticed the tiny string that went around her waist and down her crack. Her incredibly beautiful cheeks swayed back and forth as she walked. At one point she turned her head towards me.

"Like what you see?" she said.

"Oh, um, sorry. I didn't mean to stare," I said, looking away.

"Why do you think I got up?" Delia said, bending over to open the small refrigerator and pull out another bottle.

She returned to her chair and took a big swig. "Ah! Good stuff," she said. "So... Julia. How come we haven't had much time together?"
