The girls sat up and scooted on either side, our legs dangling off the side of the bed. I turned and kissed Alina, sending my tongue deep into her mouth, causing her to moan with pleasure. I then kissed Alisa and at the same time reached my hands between their crotches.
“Mm!” they both moaned as their hips rose in the air.
Touching their slits was like touching melted butter. My fingers slid over their mounds and into the juices that burbled up into their slits. I found their clits and gently rubbed them.
“Oh!” Alina moaned.
“Ah,” Alisa moaned.
We took turns kissing as my fingers moved faster, dipping down into the wells of juice and flicking across their clits. As I sped up, their hips moved up and down faster.
I turned my hand so that my index finger penetrated their vaginas, and my thumb worked their clits. Pretty soon they were bucking up and down and cumming on my fingers.
“AHHHH!” they cried.
I felt more juice flow over my fingers as they came.
They both clamored for my mouth, sticking tongues inside and pressing against my lips.
“Wow!” Alisa said after we’d broken off. “Wow, wow, wow!”
“You made us cum so hard!” Alina said.
We laid back on the bed and cuddled. The two girls played with my nipples and I with theirs.
Eventually, we all heard something coming from down the hall. I had an idea what it was.
“Want to check it out?” I said, sitting up.
“Sure,” Alisa said, getting up with her sister.
We quietly left my room. Around a corner and down the hallway, a door stood open. We crept closer and stood in the doorway.
On the bed inside, I saw Peter, totally nude, holding his hard cock in one hand, positioning it to enter the pussy of his older sister Kat, who was laying on her back, legs open and shaved pussy wet and dripping.
“Fuck me, Peter!” Kat said, looking up into the eyes of her brother with longing and lust. “It’s been too long since your cock’s been in my pussy!”
“I know!” Peter said as he pushed in. “Way too long!”
Peter’s dick slipped in so easily that his pelvis touched Kat’s mound, making her ample boobs bounce.
“Fuck, you’re wet!” Peter said, pulling out, and then shoving his dick back inside.
The two began fucking in earnest. I watched Peter’s cock nearly come out of Kat’s pussy, shining with her juices, before plunging deep inside her again. Kat’s hips moved up and down, matching Peter’s rhythm.
I was getting turned on again and started rubbing my pussy. Alina and Alisa were doing the same.
“Oh, shit!” Peter called out as he pushed deeper still into his sister’s cunt. “I’m cumming!” he called out.
“Here I cum, Peter!” Kat cried, her hips and back arched up high as an orgasm overcame her.
Peter grunted as he dumped his load of cum into her pussy, and Kat cried out in pleasure at every push of his dick.
“Ah! Ah! Ah! Fuck!” she cried.
They were so caught up in loving each other that they had no idea who was watching them. The two kissed and made out, and when Peter rolled off, he looked up and saw us.
“Look, Kat, we have an audience!”
Kat looked our way and smiled. “Did you enjoy the show?” she asked.
“Absolutely!” Alina said.
“So cool!” Alisa said. “We’ve seen peter nude, but not you, Kat. You’re beautiful!”
“Wait,” I said. “You’ve seen Peter? When did that happen.”
The girls laughed.
“Well,” Alisa said. “We might have had a visit from Uncle Nik and Peter, and they may have taken our virginity as we lay on our backs on Delia’s bed.”
“Fuck!” I said.
“You got that right!” Peter said, sitting up. “It was wonderful.”
“So, Uncle Nik too, huh?” I said.
“He’s fucked me too,” Kat said, also sitting up. “He is truly gifted!”
We all laughed at that.
“What a wonderfully strange family!” I said.
We changed into swimsuits and headed to the beach after that. The girls swam and Peter snorkeled. I laid on a towel and enjoyed the beauty and togetherness of my family.
We gathered back at our place, which was on stilts over a tropical lagoon. We fixed Suruwa (local fish curry) for dinner and enjoyed some bottles of wine and a scrumptious desert of Fijian Custard Pie.
As we sat around the living room, I noticed Peter and Alina kissing. I went over and sat by them, stroking Alina’s blonde hair and running my hands up and down Peter’s strong legs.
“You know, Mom,” Alina said. “Alisa got to fuck Peter’s cock at Aunt Delia’s, but I didn’t.”
“Well, we’ll just have to fix that, won’t we,” I said. “Your brother’s dick feels incredible up inside.”
“I want to find out,” Alina said.
I kissed Peter and Alina and encouraged them to explore each other’s bodies. Soon, Peter was undoing Alina’s dress and pulling it down, revealing her lovely breasts. Peter took one nipple in his mouth and I the other. Alina started moaning softly.
As Peter began rubbing Alina’s pussy over her panties, I looked to my left and noticed Kat and Alisa in an embrace. I got up and went over to them as they kissed for the first time.
“You’ve always been a kind big sister,” Alisa was saying. “I’m really looking forward to getting to know you in a whole new way.”
“Me too, Alisa,” Kat said, brushing her long hair from her face. “I’m getting wet thinking about putting my mouth on your sweet pussy!”
“Me too!” Alisa said.
The two kissed and I watched tongues trading mouths. I knelt and put my hands on their thighs. They broke off and the three of us kissed.
I left Kat and Alisa to undress each other and turned my attention back to Peter and Alina. Peter had disrobed and Alina was kneeling in front of his cock, sticking it in her mouth and sucking on it.
“She’s doing a good job on your dick, I see,” I said as I moved near.
“It feels so good, Mom,” Peter said.
We kissed and I felt his tongue push into my mouth. I looked down to watch my daughter suck on Peter’s dick and get it nice and hard. She rubbed herself as she did it.
“I think I can help you get nice and wet, Alina,” I said. “And ready for Peter’s cock in your pussy.”
“Ooh, Mom,” Alina said, coming off Peter’s dick. “That sounds wonderful. You haven’t licked my pussy yet.”
Alina got up on the couch and Peter and I helped her strip.
“Isn’t her pussy lovely?” I said to Peter as we pulled off her wet panties.
“Oh yeah!” Peter said. “I’ll bet it tastes like yours.”
“Let’s find out,” I said, moving between Alina’s legs.
I kissed up her thighs and saw lots of juice covering her pink labia. I kissed her lips and sucked the delicate petals into my mouth, tasting Alina’s juice for the first time. It was salty and delicious.
