Grandpa’s Milk – Chapter 9

Adult story Editor June 18, 2015 Leave a Comment

I saw an underwater figure in a bikini swim up behind the girl and grab her legs and come up. The girl jumped. “Hah! I found you Lissy! You thought you could hide way over here but I FOUND you!” Lissy gasped and spun around and addressed the girl. I guessed she was a younger sister. “Marcy! you’re such a dweeb! Can’t you leave me alone?” Marcy stuck out her tongue at her. “Hi! I’m Lissy’s younger and smarter sister, what’s your name?” she asked me. “Well, I’m John! Nice to meet you and Lissy.” She shook my hand.

I could see her gaze go from our hands to the water in between us. Her eyes widened. “Excuse me…” she put her goggles back on and dove underwater and came right back up. She grabbed Lissy’s arm and pulled her a couple steps away from me. She cupped her hand around lissy’s ear and whispered excitedly while staring at me. Lissy whispered back. It was a long explanation. Marcy’s expression went from concern to disbelief to wonder and then she giggled. Lissy brought her back to me.

“Mister John, I know I promised not to tell anyone, but Marcy…” “I know—she saw my penis, didn’t she?” “Yeah, so I had to tell her so she didn’t freak out…” “I’m so sorry, Marcy, I hope you weren’t scared, it was just an acci-“ “Can I touch it too?!” she interrupted excitedly and put her goggles back on and went underwater in front of me. She grabbed my shrinking cock with one hand and felt up my balls with the other. She came up wide-eyed, “Your wiener is SO big, Mister John- not like my brother’s!”

Lissy whispered in her ear again and grinned. Marcy’s eyes widened again. They both went under and one hand stroked my cock up and down and the other played with my balls. The Cialis was doing it’s job. My cock responded quickly and hardened in the hand. The other hand went from my balls to join the other gripping my rock-hard cock. They both came up giggling. “I TOLD you!” said Lissy. “OH WOW, it’s HUGE!” declared Marcy. “But is he going to…” “No, it just DOES that when you play with it! –Right, Mr. John?” I whispered, “Yes, just because a boy gets a boner doesn’t mean he’s going to fuck you—at least not without your permission.” “Feel how BIG it is, Lissy!” Marcy reached down and grabbed my hard-on, “Could you get that into your vagina?” Lissy grabbed it too. “I don’t know,” she rubbed it up and down, “It’s only a little bit bigger than Mom’s ‘buzz-boner’.

And we put THAT in our pussy’s!” “Now hold on a minute, you two! Nobody’s putting my penis in their vagina!” “But Mr. John, I WANT to- you have my permission. I just want to see if it FITS…” She looked around, the nearest person was 100 feet away. She reached down and slipped her bikini bottoms off. “Here, hold these, Marcy.” “Lissy!” I protested as she wrapped her legs around my waist. “Oh, come on, Mr. John, it’ll be FUN!” She reached down and positioned my cock on her vaginal opening and applied pressure with her legs.

The head popped into her warm canal. She smiled, “It’s going in, Marcy!” “Oh, Lissy, this is so COOL!” She went underwater to watch as Lissy pushed harder and my cock slowly slid into her tight love tunnel. She got about half of me in and seemed to hit a barrier. She reached down to feel my cock. “Just about there!” She looked up at me and smiled. She took a couple slow, deep breaths and I could feel her pussy muscles relax. She gripped my waist with her legs and shoved the rest of me into her tight little cunt.

Her eyes widened and she grinned, “I DID it! It’s ALL the way in me!” Marcy surfaced, “Lissy! That’s so COOL! You got his HUGE BONER into your pussy! How does it FEEL!” “My pussy feels so FULL!” She shifted her hips around. “M’mm, now it’s getting hot!” I could feel her pussy heating up, too. She started breathing heavier. “Oh, Marcy! It feels GOOD!” She tilted her pelvis a couple times and she started panting.

“OH GOD, Marcy, I’m getting a “tingly” in my feet—now my legs—now my HM’mmmmmm—-HM’mmmmmm” she stifled a high pitched scream and her body went stiff with the occasional twitch of her hips. “HM’mmmmmmm—OH MARCY—-HM’mmmmm!” Her vaginal muscles rippled up and down my cock but there was no orgasm brewing after having been sucked dry by Courtney just 20 minutes earlier. In fact it was the drug that was keeping me hard. Lissy calmed down and said, “Mr. John, that was the best ‘tingly’ ever! Thank you for letting me put your penis in me!”

“Come ON, Lissy! Get OFF of it it’s MY turn…” Marcy urged. Lissy pulled herself off my hard-on. “Hey, I don’t remember offering rides!” “But Mr. John—you did Lissy with your boner! Now I need a ‘tingly’, too, REAL BAD!” She was holding her crotch with both hands and looked up at me, “PLEASE?!” “Oh, alright…” She whipped her bottoms off and practically leapt onto me. “Oh, GOODY!” Lissy went underwater to watch. Marcy rubbed the head of my cock up and down her slit then she clamped her legs against my butt.

My cock slid halfway into her hot, lubricated, tight little vagina. “OH, yeah!” she said, “Put it ALL in, Mr. John!” She tilted her hips and gripped me with her legs and my pelvis met hers. “OH—WOW!! Mr. JOHN! Your boner is wonderful!” Lissy came up and stated the obvious, “You DID it, Marcy, I SAW it go into you all the way! That was SO cool! Now—try and have a ‘tingly’…” I don’t think she had to try very hard. She was panting already. I thought my cock would have been getting used to tight holes by now but hers was maybe the tightest—at least as tight as Sarah’s. She tilted her pelvis back and forward barely able to move on my penis.

She panted heavier, “Oh, Lissy, I feel it coming…” I felt my loins tighten up with an impending orgasm- sending more blood into my penis. “Oh my god! Mr. John! What are you DOING?!!” I could feel my cock head expand inside her. My cock swelled in both girth and length. “Mr. JOHN! GH’MM—–GH’MM—–GH’MM….” Her orgasm brought on mine and we rammed the newly created length into her love hole, grinding pelvises. “OH SHIT!” I managed to whisper, my hips humping wildly into her incredible tightness. I don’t know if I had any semen but it was mind blowing. “OH, Lissy, OH, GH’nnnnnn……GH’nnnnnnnn…” My orgasm set her off on her second. Her convulsions slowed to hip-twitches, “Mr. John! I had TWO ‘tingly’s’! How did you DO that?!!”

My cock quickly deflated and slipped out of her. “Well, girls are lucky. They can have as many ‘tinglies’ as they want! Next time you use your Mom’s “buzz boner” you can try it! Now, get your bottoms on- somebody’s coming…” I quickly tucked my ‘junk’ back into my shorts as a 30-ish woman walked towards us. “Hi, Mom!” the girls greeted happily. “Is everything OK?” She looked at me, concerned. “This is Mr. John. He was showing us a snake!” Marcy fibbed. “Yeah!” agreed Lissy, “And then we found a bone!”

They giggled holding their mouths. “And we stuck the bone in a hole…” Marcy continued the story, her mother completely confused, “Then we took the bone out and stuck it in another hole!” Lissy finished, “Then the bone turned into a snake and swam away!” I shrugged my shoulders and looked at their mother smiling. “I hope they’re not bothering you, John!” she said to me. “They’ve been telling stories since I met them. It’s OK- I have 3 granddaughters just like them. I’m used to it…” “Come on, girls, it’s time to go…” She turned and started walking away. “Thanks for the bone, Mr. John!” Lissy said, grinning, and she reached into my trunks underwater and gave my cock a squeeze as she followed her mother.
