Erik: An afternoon with mom and sister

Please note : This story is completely fictional!

"mom," I admitted. "Laura saw us when we were together. Did you know that?" I was worried that all our fun was over.
"No, honey," my mother answered, but she did not seem to be very concerned about my revelation.
"And... uh... Laura and I did some things together. I couldn't help myself, mom. We were just fooling around."
"Did you put your penis in her, Erik?" My mother now seemed more concerned and fixed her eyes on me.
"Yes, mom," I admitted. "Oh, but not in her pussy, just her mouth."
"In her mouth? Are you telling me the truth?"
"Yes, mom, I sucked her cunt, and she sucked my cock." My mother looked relieved, but she sat there a moment as though pondering deeply what she had just heard. "A few times," I added. Mom shook her head and smiled faintly.
"Go get Laura and bring her here, Erik," mom requested. My sister and I were both home from school because of the holiday. We had slept in, and now it was early afternoon. I went to fetch Laura.

"You two have been having a little fun," mom acknowledged as we both entered the room.
"Yes, mother," we replied in unison.
"Would it be nice to have fun together?" she asked.
"Yes," I agreed quickly. What a great idea!
"But, mommy," Laura said with a perplexed look, "Erik is the only boy. Would we need to share him?"
"Don't worry, sweetie, I have a lot of little games we can play to amuse ourselves. Some are boy-girl games, and some are girl-girl games. You'll see. We have an afternoon to fill up with games."
This sounded like fun. I wanted to see the girl-girl games. The idea of 18 year old Laura and my mother doing something naked made my young penis come to attention immediately.
Generously I offered, "Why don't you and Laura do your game first. I would like to see it."
"Why don't we go out to the pool," mom suggested. "Have you two ever heard of skinny dipping?"
"That's swimming without clothes on," I replied. Mom nodded.

I was sent ahead to get out the cushions and skim off the dead bugs and leaves. My step-dad treated us well even though he and mom were no longer close, and our house had a small swimming pool in the back yard; it was surrounded by a high fence, so it was very private.
Mom and Laura appeared. Mom had a tray of snacks and drinks, and Laura had our swimming suits.
"I thought you said we were going skinny dipping," I said.
"We are," mom answered, "but we have the suits handy in case someone shows up. Now let's get these clothes off." Without any hesitation, mom pulled up her top and unfastened her bra.
I was so interested in what I was about to see that I just stood there until mom reminded me to get undressed. I glanced at Laura. When she pulled off her top she was bare, and little puffy titties were right there. I took off my t-shirt; my head was free in time to see mom slip her shorts down. A few little hairs peeped around the leg elastic of her sexy panties. When Laura pulled her panties away, she had the little fuzz above her cleft.

My cock was hard, and, when I pulled my briefs off, it popped out like a steel spring. Laura giggled. My mother eyed the erection with a smile, perhaps recalling how good a fifteen year old cock had felt deep inside her neglected pussy.
"Maybe we need to take care of Erik first, mommy," Laura said and giggled. She thought she was so smart.
"No, dear, Erik offered to let us have some fun first, so he can watch and hold onto that penis tight while he observes us. Come over to mommy, honey, and sit on my lap."
Laura sat on my mom's lap, and my mother began kissing her on the lips just as she did to me and my step-dad. I didn't know that two girls could have fun like that. Soon they were lying back on the cushions, and Laura was sucking on mom's boobs. Next, Laura was on top of mom, and mom was sucking Laura's little titties. My cock became harder and harder, especially when I saw their fingers creep between each others' legs.

At my mother's urging, Laura moved up more and straddled mom's face with her slim hips. I could see mom's mouth working on my sister's cunt. Soon Laura began to moan and quiver.
"Oh, mommy, that feels so good," Laura groaned. "Please don't stop, mommy. Yes, mommy... yes, mommmmmy... MOMMY... YESSSSS!" Laura froze on top of our mom, overwhelmed by her climax.
My mother had spread her legs apart as she licked Laura's pussy, and I had been drawn closer and closer. She spread her legs so far apart that she had to put her feet on the ground. That's when I leaned onto the cushion and began to kiss her inner thighs and rub my hands over her smooth curvy legs. I could see that mom was still licking my sister's pussy even though Laura had already come.

"Oh, Erik honey, that's right. Help mommy feel good."
I did not neet much urging from my mother. My mouth was working closer to her wet snatch. I could see the inner pink folds, dewy with her juices, peeking out from between her outer lips. Just as I planted my first kiss on her pink folds, Laura cried out again in her passion as mom brought her to another little orgasm.
I became so involved with eating my mom's juicy cunt, that I ignored Laurs when she finally climbed off mom's face and knelt down near me. I just kept on kissing, licking, and fingering mom's pussy.
"Do you want me to take over," Laura asked.
"MMMMM... nooo... mmmmm," I mumbled with my mouth full of pussy and pussy juice. I wanted to bring mom off. In a few minutes, mom's pelvic gyrations became more urgent and she pulled my face against her oozing snatch.

"OH GOD," she groaned. "Erik, my sweet boy, you really know how to eat a woman. You are so... SO... GOOOOOD... OH YESSSSS!" She threw her hips up against me as she came. I rolled away soon, and Laura took over and began to lap up mom's slippery emissions.
Laura did not hold back, but attacked mom's cunt with vigor. As my sister worked mom's twat, I moved up and kissed her and caressed her big breasts. Soon mom groaned again and held Laura's head between her hands as her hips undulated against my sister's face.
