When I was in high school my family liked to camp on the Illinois river. My dad had a friend who had a cabin on an island that was secluded from the main river by a fork in the river that surrounded the island. It was only accessible by boat. We had a 14 ft runabout and we would pack our stuff and boat to the island.
My dad, mom, my sister Sandra, who was 17 years old and me, Josh, 16 reserved the cabin for the first week in July. We packed our things in the boat and my dad piloted us to the island. It was a small island, maybe an acre with a sandy beach. We always brought our swim suits and as I grew older it became a bit of an issue because my mom and sister were both blessed with large boobs and perfect round bums. I wore trunks with longer legs to better hide my erections.
So this trip we were on the island and my dad had to work so I would take him to his car and then go back to the island. The first day I did this when I returned, I turned into the inlet where the island was and was surprised to see my sister sitting on a beach towel topless!
I pulled the boat into the dock and jumped out onto the wooden surface.
My sister called to me, “hey Josh! Come here and we can swim!”
She acted like it was normal to go topless!
“Uh, you don’t have your top on!”
Sandra looked down at her boobs, “oh, wow! I am topless!”
I couldn’t take my eyes off her boobs. They were firm and just jiggled a little. She had large pink nipples that looked like big pencil erasers.
Sandra looked down at my crotch and giggled, “I think you like my tits!”
“Geez Sandra, what if mom sees you!”
“You know mom, she’s still sleeping. But hey! I have an idea!”
I was afraid to ask what it was. My sister is very wild and naughty but this is the first time she acted this way around me. I mean showing me her boobs and all.
“Why don’t we go see if mom is really sleeping? I want to have some fun with her. She was really drunk last night so I don’t think she’ll wake up.”
She was my big sister and I always did what she wanted. We went to the cabin and sure enough, mom was still out on her bed. She was on her back with the covers half off, one leg visible to the thigh.
“Shhh!” Sandra said as she pulled the covers off. Mom was wearing a loose tee and dad’s boxer shorts. Giggling, Sandra pulled the tee up exposing mom’s breasts. “Oh wow, they’re really big and floppy!”
She was right, they sagged to her sides almost resting on the bed. She had a big belly too and it hung over the boxers. I was really hard as Sandra tweaked mom’s nipples, “see, we can do whatever we want, she won’t wake up.”
“Help me get these boxers off!” I lifted her hips and Sandra pulled her boxers down. She had a very hairy muff, thick black and kinky. Sandra spread her legs and used her fingers to spread her labia, “wow! She’s got a big hole! Look at that!”
She rubbed up and down mom’s cunt then put a finger in her.
“Wow! She’s getting wet! I’ll bet she’s having a dream, thinking it’s dad. Feel this, Josh!”
I put my finger in her slit and rubbed, then pushed it in. She was incredibly wet and when I pulled my finger out, it had gooey juice on it.
I was rock hard now and Sandra told me, “take off you suit. I want you to fuck mom!”
I was ashamed to say that I didn’t hesitate. I stripped out of my suit pants and Sandra took her bikini panties off.
“Now get on her and put your cock in. I’ll help hold her if she wakes up.”
I got on top of mom and Sandra grabbed my cock and guided it in to mom’s cunt.
“Oh, holy fuck! This feels really fucking good!”
“Is this your first cunt, little bro?”
“Ohhhhhhhhh yes! Oh god! It’s amazing!”
I started to fuck mom with quick, rabbit like strokes.
“Slow down, you’ll cum too fast that way.”
I slowed down and we could tell mom was feeling me. She was starting to push back and then murmured, “oh god, Gerald! You’re so big and hard!”
She must have been dreaming. But then she started to open her eyes!
“Josh! What! Oh my god! Get off me! What are you doing! Oh god! You’re inside me! Ohhhhhhhhh no!”
Sandra held her arms while I continued to fuck her. I could tell she liked it because she was still pushing back at me.
“Oh god! Oh my god! We can’t! Oh god! Ohhhhhhhhh god!”
She jerked around, trying to knock me off of her but Sandra and I were too strong for her.
“Oh please! Stop doing this, Josh! You’re my little boy! Oh god! Nooooooo! Oh god!”
Then she seemed to give in to the feelings in her cunt, She stopped struggling and Sandra let go of her and laid beside her. She rubbed her tits and then took a nipple into her mouth.
“Ohhhhhhhhh, Sandra! Oh my babies! God damn you both, You’re making mommie feel so good! I should stop you but, Ohhhhhhhhh god yes! Fuck me, Josh! Oh god!”
I looked down at my mother beneath me, her legs spread and my cock slicing in and out of her cunt. It looked nasty, all wet with matted hair and dark lips. I couldn’t believe I was actually fucking! And with my mom and sister! An hour ago I would never have thought this was possible.
Sandra took her mouth off of mom’s nipple and begged me, “please fuck me now Josh! Oh god! I need your cock!”
I pulled out of mom’s cunt and got on top of Sandra and she guided me in to her cunt! She was a lot tighter than mom, which was surprising considering she would spread her legs for almost anyone! Not that that was a bad thing!
I watched my cock spread her cunt and felt the slick, hot inside of it! It was like a silk glove caressing my cock.
I reached between mom’s legs and put a finger in her cunt. It was incredible wet as I sawed my finger in and out. She grabbed my hand and moved it up to her clit.
“Ohhhhhhhhh god honey! Rub my clit! Rub it hard! Ohhhhhhhhh yes!”
I don’t know how I got so lucky to have sluts for my mom and sis! I knew from then on I wouldn’t lack pussy!
The feeling of my first time fucking and the fact that it was my mom and sister made it impossible for me to last.
“Oh god! I’m gonna cum pretty soon! I can feel it!”
Mom cried, “oh yes! Cum in me! Please! Put your cock back in me!”
I barely got my cock out of Sandra and into mom before I started cumming!
“Oh yes! I’m shooting it in you! Ohhhhhhhhh fuck!”
“Oh yes baby, fill me! Oh god!”
Mom was slamming her cunt up at me and I thought I would never stop shooting into her! It just kept squirting out deep in her cunt!
“Ohhhhhhhhh Josh! I’m cumming! Oh my god! Oh my god! Oh my god! Oh! Don’t stop! Ohhhhhhhhh yes!”
My thighs were tingling and I thought I would pass out, but finally the feelings ebbed and my cock started to deflate. It slipped from mom and cum poured out onto the bed.
Mom cradled my head against her breast and hugged Sandra to her body.
“I should be furious at you two for doing this but I haven’t had an orgasm from fucking in longer than I can remember. Your dad just shoves it in and cums in about a minute. I never have a chance to cum.”
Needless to say, after that it was almost nonstop fucking at the camp while dad was at work. It continued to this day at home. Every chance we get were fucking somewhere in the house.
