I wrote this some time ago, second of four parts and submitted to the forum where is was well received and it was suggested that the wider audience might like it to, so have a read and let me know.

Mummy, Mummy, guess what I just found out?" Ashleigh, my newly turned 18-year-old cheerleading daughter, rushed in breathlessly.
"Well, tell me already,” I shot back. I wondered what could be so important…
"I just found out that Daddy’s going to be out at a meeting this weekend, and we’ll have the house to ourselves."
"And what does that mean?" I asked innocently, knowing what Ashleigh meant all along.
She crumpled up her nose and said "M..u..m. It means that you can make me feel good again, with your finger in my pussy." She had picked up on the vernacular quickly, to my delight.
"Well, if he’s going to be gone all weekend, we might have time to do other things too! Are you interested?" I asked.
"What other things, Mummy?" Now I knew I had her. Her big brown eyes were so full of curiosity.
I replied with a question of my own. "Do you remember how you felt in the living room when you had your orgasm? What I’ll show you later will just make that even better."
"Oh, Mummy, I’m not sure it could be any better than before."
It turned out that my husband was actually leaving this evening for two full days, so I began to plan the events of this weekend. First thing I did was order Ashleigh’s favourite pizza. This got her into a kind of festive mood, so that she would be more relaxed. Then I told her to go get her bath, so that she was nice and clean. Then I told her to come into my bedroom after her bath.
When Ashleigh was finished her bath, she came to my bedroom wrapped in her favourite plush yellow towel. I was still in all my clothing, lying on my bed. "Come here, baby girl," I said, and she walked over to my bed. "Let me see my pretty little lady." She pretended to be shy, and only lowered her towel to the tops of her boobs, "More," I said, and she exposed her boobs and belly, but stopped there. "Come on, Ashleigh, I want to see it all." Finally, she dropped her towel, then did a slow spin. Her 32-B boobs were just as beautiful as I remembered, her pussy had just a little growth of pubic hair, and her butt was nice and round. "You are absolutely beautiful, " I gushed.
"How about you, Mummy?"
"What do you mean? What about me?" I teased.
"If I have to be naked, so do you, it’s only fair." Then she gave me that pout that would knock any living person off their feet.
"OK, if I have to. But you have to help." I stood up so she came to me and unzipped my dress, pulling it straight to the floor, she stepped back to gaze at my black underwear. I had put on a half cup bra so my nipples were just peaking out the top and a pair of crotch-less panties to match.
She reached out her hand, and gently touched my nipple, making it jerk in reaction.
"I didn’t hurt it, did I?" she asked innocently.
"No, baby girl, that is just an involuntary reaction to being touched," I explained. After she took my bra off, she asked what we’re going to do now. "Now, we’re going to have some fun. Climb up on the bed."
When she was up on the bed, I told her to spread her legs. "I’m going to kiss you all over, starting with your lips, and working my way down to your pussy."
"Oh, Mummy, that sounds like fun. But are you really going to kiss my pussy?" she asked.
"Not only kiss it, but lick it, suck on it, and make you come over and over again."
But then her face clouded over a bit, and she asked, "But Mummy, can I do the same thing for you?" Such a sweet child, thinking of her Mummy.
"Don’t you worry, I’ll make sure that you make me feel good in due time." This brightened her face again, and I knew it was time for the proceedings to begin.
"Now, baby, I want you to lie right in the middle of the bed," and I proceeded to kiss her, beginning with her supple lips, moving down to her boobs, kissing first one, then the other, then kissing the first one again while I played with the other with my hand. Now, she began to moan again. "Mummy, that feels so good. Please don’t stop."
"Don’t you worry, baby ? Stopping is the last thing on my mind." I then moved down to her tummy, kissing and licking all the way. I stopped to lick a few times in her first baby fine pussy hair, and then moved to the crown jewel. "Now, I want you to spread your beautiful legs far apart for me." When she did, I could see that she was already getting wet in anticipation.
I kissed her pussy, and then licked up one side, then down the other. I smelled her pussy, and it was a sweet smell, then I went for it all, licking up and down her pussy, tasting her wonderful juices.
"Oh, God, Mummy, please don’t stop! That feels sooo good!" Then, I started concentrating a little higher, licking her sweet clit, back and forth, up and down. "EEEEEEEE, I don’t think I can stand it any more!! God, this feels good!" And then it happened. Ashleigh raised her ass off the bed, got stiff as a board, and then screamed at the top of her lungs. Then, she shot her juices all over my face. I licked up as much as I could, but there was just so much, and it was so unexpected, that I couldn’t get it all, even with my mouth attached to her pussy.
"Mummy, I’m sorry, I didn’t mean to do that! I’ll clean it all up later, I promise," Ashleigh said between gasps. I couldn’t help but smile, and then she said, "Well, what’s so funny? I really didn’t mean to."
"Ashleigh, you didn’t do anything wrong or dirty, and I’m not mad. You just had a powerful orgasm, and your pussy juices just shot all over the place. We’ll clean up later."
"So that’s not pee?" she asked as she calmed down.
"No, baby, it’s just your pussy juice, and I thought it was real sexy."
She took a few more breaths, then said, "Thank you, Mummy. I’ve never felt this good EVER! If I knew that I could, then we’d have done this a long time ago. But what about you? It’s not fair that I get all the fun." There she goes again, thinking about her old lady again. What a sweet child.
"OK, I did promise you that I would show you how to make me feel good, too. Here’s your second lesson, lie still baby”.
A buzzing started as I turned on the vibrator and brought it up to Ashleigh’s knee and touched it, slowly moving it up and down and around and then over to the other knee. I moved it along the top of Ashleigh’s legs and then back down, stroking it in a circular motion over her legs before pushing the vibrator between her closed legs, all the while keeping my eyes fixed on her as I saw a shiver run through her body. I pushed the vibrator up between her legs until it touched her pubic mound, at its touch she closed her eyes and arched her back, and her legs opened slightly. I breathed in sharply in excitement when I saw her reaction.
“Open your legs” I said in husky voice, and Ashleigh’s legs began to open.
“Wider.”
Ashleigh, with all her shyness and embarrassment driven away by the sensation caused by the vibrator, did as she was told. With her legs spread in front of me I could smell the sweet scent of her excitement.
She let slip a gasp as I pressed the tip of the vibrator against her clitoris and then circled it, and then returned, this time pressing a little bit harder. Ashleigh’s hips bucked forward and her legs closed and re-opened. I was impressed with the result, Ashleigh looked like she was close to coming and I was only just teasing her at the moment. I sat back on my heels taking the vibrator away; Ashleigh opened her eyes, and looked at me.
“Please don’t stop” she begged.
“Ohhh, such a sweet little pussy, and smooth too, so young and sweet”
Ashleigh simply nodded her head, “yes mummy”.

I licked my lips slowly and then bent forward, and kissed her, on her pubic area, and then again, this time lower, and then again.
“Ohhh, ohhhh, OOOOOHHHHH” Ashleigh cried as my lips touched her clit and I ran the tip of my tongue around it.
It’s just like a little rosebud, I thought as I gently teased and flicked it with the tip of my tongue. Ashleigh squirmed and wiggled letting out a soft moan, her thighs closing and opening as my tongue toyed with her. Suddenly she let out a loud moan, as I placed my mouth over her clit and sucked it, while at the same time probing with my tongue.
“OOOHHhhh God, yeessssssssss oooohhhhhhhhhhhhh”.
I took my mouth away from her clit, and kissed her once again, she lifted her head.
“What…please….”
“shhhhh, there’s no hurry” I said, “Just you sit back and relax.”

I lifted the vibrator back up, turning it on, and gently stroked it over Ashleigh’s inner thigh, and moved it inwards in a slow circular motion. As it neared her pussy Ashleigh closed her eyes and tensed, but instead of going straight for it, I skirted around and over, teasing Ashleigh a little bit more. Even this, though, had her writhing and twisting. I had forgotten just how sensitive and frustrating it was being 18.
I allowed the tip of the vibrator to touch Ashleigh’s clit, and the effect was instantaneous, she gasped and moaned out loudly, her body convulsed and shook as her orgasm hit her. I pressed the vibrator against her clit, as her legs closed I held it there for a few minutes, before taking it away and circling it around her pussy, allowing her a moment to recover. After a few minutes, her breathing slowing, she looked at me but before she could say anything, I said.

“You enjoyed that?”
Ashleigh simply nodded her head.
“Ready for the second course?”

I slid the vibrator up to Ashleigh’s pussy, rubbing the tip over her sweet little mound, wet with her juices and then ran the tip up and then down between her pussy lips.
She let out a little moan and closed her eyes as the vibrator slid up and down, buzzing away, and then let out a louder gasp. I had pushed the vibrator into her tight little cunt, just an inch, but the effect was amazing. Thus far, Ashleigh’s sexual encounters, where nothing compared to this, this amazing intense feeling that must have been thundering through her teen body. Again she gasped out loudly as I pushed the vibrator in deeper. Ashleigh was beginning to twist and turn, moving her hips, and I had to hold firmly on to one of Ashleigh’s legs as I fucked the vibrator slowly back and forth into Ashleigh tight little cunt. Ashleigh slipped forward, and this pushed the vibrator right into her, so that my knuckles were now touching her soaking wet lips. I twisted it, as I pumped it back and forth, and each inward thrust made Ashleigh cry out loudly.
I thanked my choice of vibrator, the small one I was using had not broken my daughter’s hymen, but I did want it but that would have to wait a little longer.
I could feel Ashleigh building up to her next orgasm and I began to pump the vibrator faster, fucking it back and forth into her cunt. She was twisting and shaking so much that she was almost off the bed, and was letting out a continuous wail. Her legs clamped around me, and I now had to wrap my free arm tightly around one of them so that I could keep fucking her. Suddenly a small squirt of juice hit me in the face, and then another, as she was hit by her first multiple orgasm. I continued to fuck her, but more slowly, twisting and angling the vibrator, I loved the feeling of being in control, the sense of power, more so when you victim was so sweet and shy.
Ashleigh was completely lost in a storm of ecstasy; wave upon wave of intense pleasure was clearly breaking over her, as her young body writhed and twisted. I slowed my pumping down, as her convolutions began to subside and her cry’s of pleasure subsided to a gentle whimper.
Finally, I slipped the vibrator out of Ashleigh’s cunt and lifted it to her mouth; I slid it between her lips. Hmmmm the taste, sweet, I thought. I looked down at her, collapsed on the bed, her legs open, with juices flowing from her sweet cunt, red and swollen.
Reaching up my daughter kissed me on the lips; she tasted of her own sweet cunt.

"Now I feel warm all over, Mummy. And my pussy is tingling, too. Is that normal?"
"That just means that you’re horny, and need to come again. Let me show you how to do yourself, OK?" I would love to have done it to her myself, but my tongue was too tired for now, god the energy and stamina of my 18-year-old daughter was amazing.
"OK, Mummy, but hurry, PLEASE!" I told her to spread her legs again, and to put her finger inside her like I had done a while back. Then I showed her how to finger her pussy, and where her clit was, then let her go to town. She picked it up like a pro, and in just a few minutes was gushing again, though not with the same intensity as before.
"See, baby girl? When you’re all alone, you can still make yourself feel good without anyone’s help. But maybe you’d better have a towel nearby when you do."
She squeezed her naked body against mine and said "Thanks, Mummy, you’re the best!"
"And remember, this is our little secret, right?"
"Our little secret, Mummy!"
And I was already planning our next "lesson…"
