It had been amazing. What had started with our parents giving us a simple lecture on the birds and the bees had turned into...well, if you read the first part of my story, you already know.
First we saw dad fuck mom. That was an eye-opening demonstration they hadn't originally planned. Then mom gave my brother Mike a blow job. Then dad started touching my almost bald pussy. (Yes, I'm 18, but I'm not overly developed β I still have baby boobs really. Not like my mom's beautiful tits.) He was doggy-fucking mom at the time and had started to get really excited. Dave still hadn't cum, and I was suddenly feeling really hot, so mom and dad let Dave do it to me. It felt so good, but he shot his load into me so quickly that I really, really, really needed more. So, eventually, I persuaded mom to let dad do it to me. Well, his cock was so big that I needed a lot of help from mom to get it into me, but when it slid all the way in β my head just exploded. It was AMAZING. Mom got so excited by watching me ride my dad's monster cock that she helped Mike fuck her ass.
But when it was all over, mom came to her senses.
"Yes, this was fun," she said, "But this is the last time it will happen. Okay, everyone? The class is over. No more of this will be happening. And I don't want either of you to have sex with anyone until after your 21st birthday. Understand?"
We went to bed soon after. Even though the Birds & Bees lesson started at only 7.30, it was after 11.00 by the time we finished. But even though I was tired, I could hardly sleep. First, my pussy was soooo sore. I'd fingered myself regularly, but never had a cock in it β especially one as big as my dad's. But mainly I was just buzzing. I'd often thought a about sex but never dreamed it could be so good.
So for a long time, I just lay there in bed. My hand was on my pussy, softly rubbing it, like a bruise, but a lovely bruise, remembering having my dad's cock in it β and Mike's. Without really noticing, I started to rub my clit. That was one very useful lesson mom had taught me. Why hadn't I thought of doing that before now! Suddenly I found myself moaning softly. I hadn't wanted to, but I was making myself hot again. I kept on thinking about how I lowered myself down on my dad's cock, how mom lubricated my pussy to help, and good it felt when I slid all of his nine inches into me.
I crept out of my bedroom, down the hall, and stood outside the door of my parent's room, rubbing my clit every step of the way. I don't know why, maybe I just wanted to be near my dad's cock. The door wasn't fully closed, and I was surprised to hear that my parents were still awake. They were talking, and my mother sounded very concerned.
"That was terrible. We should never have let that happen. We're awful parents. How could we do that?"
My dad didn't say anything. Mom kept talking.
"Poor little Julie. You almost split her in half with your huge cock. I hope we haven't put her off sex. How could you do that to her."
My dad didn't want to take all the blame.
"It wasn't my idea. She wanted it. And you were the one who lubricated he pussy for me. You seemed to enjoy that a little too much, I thought."
Mom went quiet for a moment, then spoke.
"She has a lovely little pussy. I wanted to lick it, but that would have been awful of me."
Dad laughed.
"Well you didn't seem to mind sucking Mike's cock."
Mom kept her tone serious.
"Well, I was impressed by his cock. It was so big and firm. He'll be just as big as you one day, maybe bigger."
Dad agreed.
"Yes, he's a chip off the old block. And he certainly didn't mind using it, either. He gave it to Julie real good. And to you. I was surprised you let him fuck you up the ass."
"Well, I suppose we'd gone so far by then that nothing seemed to matter anymore. But we'll have to keep on eye on them for a while, in case they want to do it again. They seemed to enjoy it a little too much, if you ask me, and I don't want them fucking each other every time we turn around. That goes for you too. "
Dad laughed.
"Okay, I'll leave Mike alone."
But mom was having none of that.
"You know what I mean. You seemed to like Julie's tight pussy an awful lot. So leave it alone."
"Okay, I'll leave her pussy alone."
Mom saw through him right away.
"Leave all of her alone. That includes her mouth and ass. She's still an anal virgin and we should leave her that way. And anyway, there's no way your cock could get into her tiny ass. You know that."
Dad suddenly changed his voice to a funny, deeper sound.
"But my cock fits just right in your ass..."
Then they both laughed and I heard some shuffling and grunting and right away I knew exactly what was happening. Suddenly I heard a whispered voice at my ear.
"Dad's fucking mom's ass."
I almost hit the roof, I jumped so high with fright. It was Mike. He'd been standing behind me the whole time, listening into the conversation.
"Mike! You scared me! What are you doing here?"
"Same as you. I couldn't sleep. Hmmm...lucky dad. I loved fucking mom's ass. It was so tight."
"Well dad says my ass would be much tighter."
Mike laughed.
"Of course it is, it's never been fucked. What are you doing?"
Mike had suddenly noticed that I had my fingers in my pussy. I hardly knew it myself, but I'd been fingering my pussy the whole time I'd been listening to mom and dad talk. I made an excuse.
"It's just...um...it's sore, so I'm rubbing it."
Mike smiled.
