Grandpa's Milk- Chapter 11

... back to me her gaze went down to my crotch and she dropped the cookies and gasped. “Tanya!” Terry scolded. Her sister glared at her wide-eyed and then returned her gaze to my ‘package’. Terry followed her gaze and her eyes nearly popped out of her head. “Oh, goodness,” I exclaimed, “My fault- I wasn’t watching…” I said and I squatted down to start picking up the loose cookies. My cock and balls dangled beneath me. They both got on their knees and tried to help but they couldn’t take their eyes off my cock. I sat back down and munched on a cookie seemingly oblivious to my exposure. They looked at each other, incredulous, and giggled covering their mouths with their hands. Tanya leaned over and whispered in Terry’s ear and they giggled some more. Terry pulled out one of the ten dollar bills and handed it to me. I looked at her puzzled. “For ‘presentation’” she said, and they both laughed while staring at my cock. “Did you enjoy that?” I asked. “That’s what you came for wasn’t it? Roxy told you ALL about me didn’t she?” I handed back the 10 spot. “Yeah, but only because we MADE her!

And it’s beautiful! Right Terry?” Terry just nodded, smiling, staring at my manhood. “Roxy said you let her touch it, and suck it, and even let her put it in her VAGINA! Is that true, Grandpa John?” “Well, yeah…” I tried to explain. “She says,” she continued, “that girls can make you get a boner and make your sperms shoot out of your penis. And the sperms make girls’ titties grow REAL FAST and she has big boobs, so it must be working!” “Well I don’t know about THAT…” “Tanya! LOOK!” The twin pussies on display in front of me and the talk of boners, and sperm, and titties finally translated to the inevitable consequence- penis blood pressure! “Oh my god! It’s growing!” Terry’s eyes grew in awe of the miraculous thing happening before her eyes. “Are you going to make a boner for us, John?!” “That’s amazing, Grandpa John!” Tanya exclaimed in total wonder, “How do you DO that?” My penis slowly transformed itself as they watched wide-eyed.
