Saturday

My name is Steve, I am 18. I have a sister called Jen and live with our Mum Sally who is 36 our Dad died when I was 9.

It was a lazy Saturday by the pool as I watched my sister lying in her bikini taking in the rays. Jen is younger than me but already her breasts are developing and her long legs set off her figure nicely.

I stroked my cock through my shorts as I watched her sunbathing then I slowly got up and headed to the bathroom to shoot my load. I cleaned up and went back to the pool.

It was 45 minutes later when I heard Mum call us in for dinner. We ate and then Jen went off to bed around 8pm.

I was sat playing on my phone when my Mum came back into the lounge. She sat next to me and watched me playing for a while then asked “Do you think Jen is hot?” I froze, losing my life in the game. “It’s ok” she laughed “Jen is very good looking” she added. I looked at my Mum. “I saw you watching her this afternoon; stroking your cock before cumming in the bathroom.” I began to go red. Mum laughed again. “Do you think I am hot?” she asked. “Mum!” I said. She laughed again, “of course you do. I have seen you watching me when I am in the pool, looking at my tits watching me as I lay down, staring between my legs when I leave them open.”

I hadn’t noticed my cock had begun to harden, but my Mum hadn’t. “You already getting hard just thinking about my tits aren’t you.” I look down at my growing bulge in my trunks. My Mum pulled her t-shirt off over her head, she had no bra on and her 34C tits were inches from my face. “Go on feel them” she said. I just stared at her tits. She took my hands and placed them on her tits. “Feel how nice they are and how hard my nipples are going.” “Fuck” I said. “We can do that later” my Mum smiled but first I think you better get your cock out before your trunks split open. My Mum pulled my trunks down and grabbed hold of my cock. “Oh my it is so much bigger than your Dad’s was.” She looked into my eyes then bent down and took it in her mouth. My Mum sucked the end and her hand rubbed the shaft and I exploded into her mouth. My Mum removed her mouth and looked at me then opened her mouth to show me it full of my cum then swallowed it, wiping the dribbles from the side of her lips she smiled and said “I want more of that.”

“Come with me” my Mum said and she led me to her bedroom where she told me to lay on the bed. I did as she asked and she slid off her shorts and panties revealing her shaven cunt to me. “Time to learn how to make me cum” she said then she climbed onto the bed, straddled me and lowered her cunt to my mouth. “Lick my cunt. Make me cum” she said.

My Mum coached me as I licked her cunt as my tongue slid between her cunt lips and found her clit her cunt began to flood juices. “That’s it lick my clit” she yelled and as I did she orgasmed her cunt gushing over my face.

My Mum fell to the side panting as I licked my lips and wiped her juices from my face.

“I think that’s enough for tonight” she said “you know you can’t tell anyone about this.” I nodded my cock hard again I stroked it up and down. My Mum slid off the bed and walked towards her shower. She looked at my hard cock “Oh fuck it” she said and lent over and sucked my cock again until I filled her mouth once more. She swallowed and went into the shower. I followed and watched her then slid in beside her. Once clean she told me go to my own bed. I did so reluctantly, my head in a spin.

Sunday

It was 9.15 when I heard Jen calling “Get up Steve breakfasts ready.” I got up slid on a pair of shorts and a t-shirt and headed down to the kitchen. “Morning” said my Mum “you slept well” she smiled.

Again the weather was great and already 24C. Jen was in a blue bikini that hid nothing. I had to keep myself from looking at her, but it was hard as my Mum was also in a bikini which also hid nothing.

Jen finished her cereal and headed to the pool. I ate mine slowly watching my Mum’s ass as she washed up at the sink. “I can feel you staring at my ass” she turned and smiled. She walked to the table and her hand slid down to my cock. “I can’t wait to get this back in my mouth” she laughed and went outside to join Jen. I headed to the bathroom and shot my load.

Joining Jen and my Mum by the pool I jumped in and swam back and forward to keep myself distracted from seeing them in their bikinis.

Eventually I got out and went inside and watched Jen and my Mum from the window, my cock getting hard once more. I saw them get up and head towards the door so I grabbed my phone and began to play a game.

The rest of the day went by with Jen going in and out of the pool and Mum cleaning as I played the game.

At 8pm Mum told Jen to go to bed and once she had gone she said “Come on” as she led me back to her bedroom and straddled my face again.

She orgasmed again but instead of climbing off she slid backwards and lowered her cunt over my cock. “That’s it Steve, fuck your Mum, fuck me hard and fast.” My Mum rode me as I tried to slide in and out as fast as I could before I shot my load into her cunt. “We need to practice that some more” she laughed as she slid to the side.

4 Weeks Later

Over the next 4 weeks, I had fucked my Mum almost every day and when she had her period she sucked my cock anyway.

Jen had gone to bed and my Mum sat beside me on the couch. She opened my shorts and took my cock out and slowly stroked it. She smiled “I bet you would like Jen to be doing this to you. Her small hand gripping your cock as you played with her tits.” My cock was rock hard “Or having your cock jammed into her tight virgin cunt hole making her orgasm.” I shot my load it shot into the air and landed on my t-shirt. My Mum smiled “well maybe one day but now I need my cunt filled” she pulled off her shorts and slid he cunt over my semi hard cock.

My Mum orgasmed almost instantly then she led me to the bedroom.

“It’s time for you to learn” she said. “As well as putting you cock in my mouth and cunt you need to use dildos and your fingers.” She took a dildo from the draw and showed me how to insert it and move it in and out. “With practice you will be able to make me orgasm with it.”

She placed the dildo to the side. “Now take these two fingers and push then into my cunt gently and move them in and out and curl them up inside me. Once you feel me getting wet insert a third then four fingers.” I did as she instructed my fingers slowly filling her cunt which was now very wet. My Mum’s breathing was getting short. “Now slide your thumb inside and make a fist and push it into me” she panted. I made the fist but I could not get it into her cunt. “You need to turn your fist from side to side. I tried again her cunt gave a little. “Oh fuck” my Mum said as she neared an orgasm “Use your fist and punch my cunt” she screamed. I pulled my fist back and punched her cunt 4 then on the fifth time my fist went into her cunt past my wrist. My Mum shuddered on the bed her hips bouncing and her cunt sprayed juices into the air. “punch your fist in and out” she panted I did as she asked and her orgasm stopped then came a second time as I fisted her before she gasped “Stop.” I pulled my fist from her cunt which was wide open and pink and flooding juice. I looked down at my cock which was dripping a thick wad of cum.

My Mum panted for a few minutes before she said “holy fuck I have never cum like that before.”

She looked at the bed and said “guess these sheets need a wash” she led me to the shower and we cleaned up then she bent over and sucked my cock until I came in her mouth.

5 Months later

Sex with my Mum continued on a daily basis but it was getting later on a night as Jen was now allowed to stay up until 9pm.

“What do you want for your birthday?” my Mum asked as we sat at the table eating dinner one evening. I looked at her then Jen and smiled. “I will have to think about it” I lied.

Jen said “I could get you a game for your computer.” “Ok” I said “there’s a few new ones out.” I looked back at my Mum who had gone over to the sink behind Jen. She looked at me then slid her hand down the front of her shorts and rubbed her cunt. My cock went hard and I looked away.

Jen cleared the table and went to do her homework. My Mum walked over to me. “You want to fuck her for your birthday don’t you” she laughed.

At 9.30 I was on top of my Mum fucking her as hard as I could my cock rock hard thinking of fucking Jen. I shot my load but my Mum wanted more and had me fist her to orgasm then she sucked my cock dry.

Mum’s Idea

Jen was at her friend’s and was due home at 6pm. “I want Jen to see us fucking” my Mum said “that way maybe I can coax her into joining us.” I looked at my Mum. “Jen will come in as usual and head to her room. She will not notice we aren’t in the lounge but she will hear us in the bedroom. We can be on the bed and with me on the top I will be able to see her at the door if I leave it slightly open.”

“She might just go to her room but she might watch and I will try to get her to come in closer.” If she does watch I will say ‘deeper’”

Just before 4pm we headed up to my Mum’s bedroom where as I laid on the bed my Mum set the door ajar just enough for Jen to see through the gap and for my Mum to see her from the corner of her eye.

My Mum started by sucking my cock slowly then we heard the front door open and My Mum jumped on top of me sliding my cock deep into her cunt. My Mum began moaning as Jen’s footsteps got nearer then she called out “yes, that’s it fuck me harder.” My Mum rode my cock slowly leaning forwards she looked as though she was looking at the floor. “Yes, yes deeper” my Mum said.

That was the word, Jen was watching I held my cock inside my Mum’s cunt and waited. “Come in Jen” my Mum said. I looked to the side of my Mum and saw the door open slightly. “It’s ok Jen” my Mum said “why don’t you strip off and rub your cunt properly.” My Mum climbed off me and moved to Jen’s side and pulled Jen’s school top off and her skirt down. “Look how your tits are developing” she said rubbing Jen’s nipples. Jen moaned “Oh you’re going to cum aren’t you, let me help” she pulled Jen onto the bed next to me and slipped Jen’s panties off then pushing Jen’s legs open she placed her mouth over Jen’s cunt and licked. Jen’s hips bucked as she orgasmed. I watched my cock rock hard as my Mum licked my sister to orgasm. “Fuck that’s so hot” I said as my cock exploded cum flying in to the air and landing on my Mum’s hair and Jen’s stomach.

Jen panting receded after her orgasm at the behest of her Mum Sally’s tongue.

My Mum’s hair dripped my cum. Everyone was quiet and me and Mum looked at Jen. “I knew Steve was fucking you” Jen said “I have heard you on a night but never been able to see you.” “Well you have now” I said.

Let’s go downstairs our Mum said adding “there is no need for clothes tonight” she said to Jen.

Downstairs Mum prepared dinner and I sat with Jen at the table. “Why don’t you too play with each other; in fact” she led us to the lounge. “Lay on the floor Steve” she indicated where and then moved Jen above me. “Now lower your cunt onto Steve’s mouth and then take his cock in yours. This is called a ‘69’. Keep licking and sucking each other until dinner is ready.”
