BACK IN 2013 i was shocked to learn how simple it really was to keep secrets especially if i was the one usually initiating the reasons behind those secrets,to begin i'm not exactly bright or popular in school or at home and pretty much just get on my mothers nerves by intentionally being lazy and irresponsable...so much so that being the only daughter at age 15 with three adult brothers all married and living apart i just did dumb shit around the house when bored.my grandfather who still lives with us was and is the only one who really understands me and always spoke to me straight to the point and without bullshit,issues at home like leaving my dirty panties in the bathtub or not taking a bath daily my grandfather would say that little ladies should never throw their female scent when crazy old men lived in the home.naturally i never considered myself attractive being short and chunky with big breast and fat butt yet my grandfather made it clear to never underestimate the horny male species that's when i met benny a tall skinny boy from school,he was kind of like having a puppy following me around and was always staring at my breast so knowing that boys were not allowed in my home i ask my grandfather to kind of lie and convince my mother that he was taking me to the movies and the truth was that while grandpa was in a bar drinking a few beers i was with benny in a park nearby having sex for the first time,let's just say benny wasn't really the boy i expected with a penis size 4 inches though he was pretty thick it felt like having a soft sponge shoved inside my pussy...he didn't even see my breast or touch them and like terrible magic he was finished in less then ten minutes not counting the few minutes it took us to find a bench seat hidden behind some trees and get naked from the waist down.he kind of felt uneasy with how i smelled sexually but like my grandfather always says to never underestimate the horny male species where pussy is concerned...he went home and i went to pick up my grandfather at the bar with benny's wasted seed sloshing around in my stained dirty panties.my grandfather wasn't blind,dumb or deaf kind of smiling at me in that naughty way as we walked back home and of course he was prone to staring at my breast and hugging me close when no one was around and it wasn't any secret between us that i was a young girl in female heat.having noted by natural causes the bulge in his pants while he sat in the living room or slept in his tight boxers i often wondered what it look like and of course it wasn't like i could go and talk with my mother about these thing like i could with my grandfather....it just happens in families more often than people can imagine,so i pretty much initiated sexual contact by simply getting my grandfather to go back to that bar from several days back and made it clear to him that not too far from where we were there was an old warehouse and quite obviously with him i didn't need to put it in writing where i was going with this...it was sincerely far more than i had expected and extremely too much for a fifteen year old girl like me to handle when my grandfather literally poked and probed his fully erect 9 inches between my thighs,i felt as if a strong stallion horse was forcing it's huge phallus up in my sweaty fat pussy and my grandfather with years of sexual mating experiences knew instinctively to hold me tight when i felt his huge thick penis barely able to stretch my pussy...my body trembled in his bearlike embrace as i cried and begged him to stop but he kept increasing each sexual thrust trying to get more of his dick and of course stimulated by his thickness stretching and moving inside me my pussy began to lubricate OOOOOOOO-SHIT-FUCK-NOOOOOOO...i yelled in despair knowing quite well that sexually my grandfather had some pussy cream to lube quite the length of his penis and obviously he went with his sexual instincts to hold me down in his vise-like grip literally ramming it up inside of me the pain of having too much dick made my knees buckle sending my grandfathers body crashing down on top of me but no matter how much i kicked and screamed in sexual pain he was determined to keep me locked in his embrace and fuck me with all that dick between his legs...for an old man of 69 years old he certainly had the sexual energy to fuck and fuck and fuck and unlike lil-benny my grandfather could orgasm and still keep going,at some point where i was to exhausted to scream or get him off me my pussy began to pulse and my grandfather could feel it as well suddenly it felt as if i had peed and my fat lil- pussy gripped his dick tight and i peed again...my eyes rolled to the back of my head and i bit the lower part of my lip enjoying how good it felt,my grandfather thrust and rammed as my pussy went up and down the length of his still erect penis as i pulsed and peed four more times then it was over when grandpa went stiff and came inside me one final time.too sore to walk we took a cab home and according to my mothers kitchen clock we were late by four hours,i gave her a hug and kiss while looking at my grandfather in that naughty way that he loved to often do then went and took a bath making sure to clean my dirty panties...truth story
