Grandpa's Milk- Chapter 9

... crotch. I gasped in feigned embarrassment, “Oh my gosh!” and quickly tucked my junk back into my trunks. “Oh, I’m SO sorry, young lady, it was an accident! I hope you’re not upset…” “No, I’ve seen my brother’s ‘thingy’ lots of times. Yours is just bigger- in fact it’s kinda cute! Can I see it again?” “You mean underwater?” “Yeah, where else?” “Oh, nowhere. Well, if you promise not to tell anyone…” “Sure, I promise…” I reached down and pulled my ‘package’ out through the leg of my trunks. She dropped underwater right in front of me and examined my anatomy from about a foot away. She came up. “COOL, mister! Are those your balls under your wiener?” “Those are my ‘testicles’, yes…” “Yeah, testicles, we learned about them in sex ed class but yours are bigger than I imagined.” She went under again. I bounced up and down on my toes to give her a show. A large bubble came from her mouth- a laugh, I expect. She came up again “That was funny, mister, do it some more!” And she went down. I bounced and twisted sending my junk flopping every which way. She came up laughing. “You’re funny mister! Your balls are SO cool! Can I touch them?” “Only if…” “I know-- only if I don’t tell on you. OK I won’t…” And she dove down again. She poked one then the other.

Try and be more gentle.” She looked at me and reached down and cupped them and gently rolled them around. “Like this?” Then she felt something else and she went down again. I could feel the blood throbbing in my loins as my penis quickly inflated. I felt a hand wrap around it and slide up and down the shaft. She came up suddenly. “OH MY GOD!” she whispered, “You grew a boner!” She looked down through the water at the wondrous thing still in her grip. “How did you DO that?! Why… “ She let go, looking a little concerned, “Are you going to FUCK me with it…” “No! I’m not going to fuck you!” I whispered. “That’s how you make a boy get a boner- by playing with his balls and wiener! If you stop touching me it will go back to normal. It doesn’t mean I’m gonna fuck you!” She looked relieved and grasped it again. “It sure grows BIG!” she commented as she explored it’s length. 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!
