Short Family Voyeour Story

Last night my vehicle wouldn't start at the mall in the evening hour (darkening), & I didn't have my phone on me topping it off. So I wasn't too far from my sister's house & decided to walk over for some help. After around 45 minutes of walking I finally made it & was soon thirsty that my mouth was very dry & went to the side of the house for the water hose & was drinking it. Turning the water off I could hear voices coming from the backyard & go check, stepping on a 2x4 board attached to the fence I popped my head over to catch there attention I was dumbstruck on stumbling on what I was seeing. My older sister getting nailed by a friend of theirs & my brother in law nailing his wife in the swimming pool. My sister was spread out knee's bent on the edge of the pool in a "V" shape with Pete's face buried down eating her snatch out rowdy!! And my Brother n law behind Erica fucking her K9 fashion & both woman moaning and dirty talking hearing my sister saying"Eat that fuckn pussy & make me cum all in your face and mouth like Mommy likes it" was like hearing fingernails scratching on a chalkboard. I got down & soaked in the horrible vision & ears. Then I should hear body's slapping and word's of "Ohh.. Yes... Fuck my cock hungry pussy with your stiff cock Baby" & curiosity got me & peeped to look at my sister's pussy getting pounded & she's enjoying it & my dick's started to rise seeing this. My sister's an attractive woman,slim,toned body from year's of soccer playing & squats displaying her well manicured backyard ass, I just never thought of her sexually but hearing her dirty talking & getting nailed I didn't see her as my sister but a horny housewife begging for cock. As I started stroking my dick & enjoying the screen,my cock got even harder seeing her turn around set him on his back forcefully & showed her cock sucking skills which I got soo... turned on... I jerked off harder n faster as I let a moan as I spray the fence with yoke thickened spunk wishing her mouth was on my prick instead. Man... She showed me She Can FUCK & SUCK REAL GOOD!!! I guess I'm proud of her. TY for reading.
