Mom shifted above me slightly so that she could make her other nipple available for me. I lightly nibbled it before sucking it completely into my mouth. I couldn't see past my mom but I could hear the slurping sound of my sister licking and sucking my cock. It was a very enjoyable feeling in my boner, made more so by my guzzling of mom's teats.
I knew that my situation was one that most other eighteen-year-old boys would envy. I suppose some might have called me greedy, having both my forty two year-old mom and twenty four year-old sister as my cum sluts, but I didn't care. I thought back happily to when it all started, which was when I won the lottery.
A month previously
The reporter was half smiling as she asked me the question, "Can you believe how lucky you are to be the youngest big lottery winner this state has ever had?"
I smiled back, "Well I guess as I bought the ticket on my eighteenth birthday, I was always going to be the youngest. As to the amount, you're right, I couldn't believe it when I saw the win was over thirty million."
"How are you going to spend it honey?" She seemed to think that it was going to be a problem for me, which it wasn't.
I looked over at my mom and sister, Sophie, who were being interviewed twenty yards away by a reporter from another news station. My sister looked gorgeous, brown hair, a beautiful face and a stacked body. She looked like a lingerie model for the fuller breasted woman. My beautiful brown haired mom was a similar height with a figure that was an exaggeration of my sister's. My sister's tits were big; my mom's were even bigger. My sister's ass was a well formed round butt; my mom's was like two footballs, with a shelf.
Both women had dressed up for the reporters, busting their credit card limits. They were telling the reporters what a close-knit family we were, which I supposed was true to a degree. Neither woman had seemed that interested in me until they had found out that I had won the lottery. Before that point they had both seemed to find me sweet and amusing but neither went out of their way to talk to me. I'd bought the ticket on the first day of my summer school break and I hadn't been expecting to see much of my family during the holidays.
Neither of them had been into work since learning of my win, although I had made plain to them that I had no intention of allowing them to build up huge credit card bills and expecting me to pay them. Dad had left home about the same time as my sister moved out when she was twenty, leaving my mom as the sole payer of the mortgage. However, my sister had to move back in two months ago as she had split from her partner, leaving my sister with debts. Now the two of them obviously thought all financially would be well.
But I was not going to make life easy for them. They had always been spendthrifts. To be fair to them, they were pretty free and easy with me, leaving me alone to play porn to my heart's content in my room. There had been an embarrassing moment a couple of weeks previously when mom decided to tidy my room. She had found a stack of DVDs in my drawers including 'Big sisters and little brothers' and 'Big breasts and stockings'. She had been looking at them with my sister when I came home and caught them laughing. Mom was just showing Sophie the cover of 'Moms ride boys', which pictured a voluptuous older woman, very much like mom, straddling and fucking a teenage boy. I quickly snatched that DVD and all the other embarrassing DVDs off them, pushed them both out of the room and slammed my bedroom door shut.
The male reporter was trying to ask mom and Sophie questions, but seemed unable to drag his eyes away from mom's chest. I could appreciate his problem. I wondered sometimes if mom was aware how much I was staring at her breasts when she wasn't looking.
"So you're looking to spend money on fine wines, Mrs. Gibson. Which of France's wine regions do you think is breast?" he spluttered, "I mean best."
Mom didn't seem to notice his word mix-up and started droning on about the Bordeaux region, which I suspected she'd just read about.
The reporter interviewing me saw me staring at my mom and sister and misread my thoughts, "I can see you're thinking of your family. Jimmy you're a very generous young man," she gushed.
I looked across again at my mom and sister and just replied with a smile, "I certainly intend to share an appropriate amount of my new wealth with them."
However, what I deemed appropriate I knew would seem insufficient to them.
As the reporters and technicians drifted off, mom, sis and I began to walk back to the house. My sister smiled at me.
"Jimmy, I've left our credit card bills on the table in your room. Be a darling and pay them for us will you?"
I frowned, "I'll think about it, but I may not pay them. I warned you and mom that you can't just spend what you want now."
I walked faster away from them and heard them muttering behind me. I guessed they were discussing how to get around me, but I was feeling quite hard-nosed.
It was in the afternoon that I was standing in the bathroom trying to find something in the cabinet on the wall, when I was suddenly aware that my sister had walked in and was standing close behind me. She started whispering in my ear.
"My credit card bill is a lot less than mom's. You could just pay mine off."
I didn't turn round to face her. "I don't think so," I whispered back.
Suddenly she put her arms around my waist and hugged me.
She carried on whispering, "I think that you really want to be kind to your sister."
I was so shocked I didn't know what to say. She had never hugged me that way before and I was very aware of the feel of her breasts in my back.
Suddenly she lowered both her hands and gripped my cock through my pants. I gasped, stunned at her action.
She giggled and whispered, "C'mon Jimmy, we both know what you want me to do now," and started unbuckling my belt.
I was transfixed, my hands at my sides, waiting frozen for what she would do next.
She didn't hesitate but, as soon as my belt was undone, started unzipping my pants. She was acting quickly now, perhaps nervous that I might attempt to stop her. Thrusting two hands down into the front of my boxers, she pulled out my cock and squeezed it in her fingers. It was rock hard in an instant and, as she gripped it in both hands, I could feel her relax as she felt more confident.
She giggled again and whispered, "Do you like your sister's fingers around your cock, Jimmy?"
This was my fantasy come true, "Oh yes," I groaned as she rubbed her fingertips over my helmet.
"The credit card bill?" she whispered as she slowly jacked me off.
"No problem," I gasped.
"Good boy," whispered Sophie as her magical fingers caressed me more firmly.
I was worried she was going to rush it, but I needn't have been concerned. She jacked me steadily and I began panting hard.
"I can't believe how big you are, Jimmy," she whispered, with another giggle.
I groaned loudly and she laughed delightedly as my jizz shot out between her fingers, splattering the bathroom wall. Kissing me on the back of my neck, she let my cock go and left me standing there.
I couldn't believe what had just happened. The experience had been fantastic. In fact it had been so good that I decided I would pay off mom's credit card bill as well. I resolved to tell mom as we had lunch together the following day.
The next day I felt somewhat in a daze. My sister had disappeared out early, no doubt to do some more shopping. Mom was in the kitchen as I entered it. She had her back to me, cutting something up. She seemed to have a T-shirt on which was so old I'd forgotten she owned it.
I moved towards the kitchen window and was staring abstractedly out of it, when suddenly I felt mom press into me from behind with her arms coming around my waist as my sister's had done the previous day. Mom's breasts felt even more substantial in my back than my sister's had done.
Mom's hands were already unbuckling my belt as she whispered, "I hear you enjoyed your sister's hands around your cock yesterday."
By the time I'd gulped and was about to respond, she'd already pulled my pants and boxers down to my knees and had grasped my cock. It sprung to a hard erection in her fingers.
She cooed in my ear. "How do you like mommy's fingers round your cock Jimmy?"
My response was just a groan as she pulled me around to face her. Her T-shirt was very low cut, her big breasts pushing out the top. I stared at those two wonderful globes, her cleavage plunging down the center.
She was smiling at me as she gently gripped my mushroom head. Pre-cum had already started emerging from my tip and she tenderly smoothed it over my helmet with her thumb. I was in heaven as she whispered, "my credit card bill?"
I was incapable of speech and could only groan and nod my head.
"I'll take that as a yes," she whispered.
She started a steady jacking movement with her right fist and tenderly cradled my balls in her left hand.
"Sophie said that you had a big cock, but I never imagined that you would be as blessed as you are," she murmured admiringly with a mother's pride in her voice.
As she worked the head of my boner, I couldn't take my eyes off her jiggling big breasts. They were jostling in time with her hand movements, which was certainly what she intended when she'd dressed, squeezing herself into that T-shirt.
"I always knew you would turn out to be a big tits man," she whispered. "I've seen you staring at my large breasts when you thought I wasn't looking."
She whispered in an even quieter voice, "I bet you've been masturbating in bed fantasizing about what you'd like to do to mommy's big breasts."
This was all too much for me and I knew I couldn't hold myself back any longer. Although in my excitement my throat was so constrained that it was difficult for me to speak, I managed to warn her.
"Mom I'm cu-"
