"She's a might frightful truth be told." Whatever that meant. I waited for more, but, confirmed she'd finished. So I went: "Sure, uh, Mrs. Ca...I mean... ma." You're welcome, Cully." Gave me a kiss on the cheek. "Good luck, sweetheart." Turned loose my arm-stalked away like an old Gypsy woman.Years later I told mother how the old Gyp had warned me. "Well, Dale, you're no picnic, son."Left hand she wrung in & out. Right hand wrung her clitoris. "Oh, fuck, Cully. Fuck, fuck, fuck. Fuck! Fuck!. We went inside, "Maybe we can catch a movie", she said.I replied "Yes, i am in the mood for a...movie".At this point my balls were swollen, full of cum.We are at the ticket line, when i whisperin her ear "Baby, i dunno about you, but if i don;t fuck you now, my balls will start floating". She laughed saying"I am so horny myself, but i didn;t want to tell you, so you wouldn;t think less of me".My blood was all in my dick, soi can;t have any thoughts or opinions now; i acted on instinct.Grabbed. Beckie looked back at me, her eyes glazed and said “Mmmm just do me quick I think I’m about to cum”.Jazz had followed me back to my room “I don’t want to be alone” she said. That was more words that she had used to me than in all my time of knowing her! My mind was in a whirl, ass fuck/frightened sister. Ass-fuck/frightened sister. “Just sit over there then and keep quiet” I said gesturing over to my chair in front of my P.C. (Not that I need to say keep quiet to her, my sister whom never. But I still didn’t know what her agenda was and was still scared of frightening her away.After wanting to pee for some time I finally built up the courage to tell her. “Mmmm, me too!” she smiled and led the way into the woods, but deeper this time. As I squatted down she said: “can I have a closer look this time?” Trying to stay calm I managed to pant a “yes” and before I knew what was going on, she was kneeling right in front of me, her hands on the insides of my knees, gently moving my legs.
