BROTHER AND SISTER GET HORNY WATCHING PARENTS FUCK

I grew up in Tempe, a few blocks from the Arizona State University campus, with my parents and a brother who was one year younger than me. Our house was kind of small….it was big enough for my brother and me to have our own bedrooms, but we shared a bathroom at the end of the hall, just past our parents’ bedroom. This wasn’t really a problem, per se, but it ended up creating a situation that changed our sibling relationship forever.

It happened in early summer during my senior year in high school. I woke up in the middle of the night needing to pee, so I climbed out of bed and padded down the hallway toward the bathroom.

It was summertime in Arizona, so I typically wore a sheer tank top over my 35E boobs, along with thong panties. Our family wasn’t overly prudish, so running around like this at bedtime during the summer was fairly typical for me.

As I opened my bedroom door and started quietly down the hall toward the bathroom, I saw my brother, Corey, standing at my parents’ bedroom door, and apparently peeking in through a small opening between door and frame. Curious, I silently tip-toed up next to him, looked over his shoulder, and received a double shock… Corey was watching my parents on their bed through the small opening in the doorway – obviously fucking – and he had pulled his cock out through the opening in his boxers, and was jerking off as he watched them.

I guess I actually received a third shock, as well….I had never seen Corey’s naked dick before, and it was much bigger and more impressive than I could’ve imagined.

Corey was so focused on watching my father pounding his cock into my mother’s cunt from behind, as she knelt on all fours…her big boobs swinging back and forth beneath her with every thrust…he still hadn’t noticed me standing next to him in the hallway.

I have to admit….watching my parents grunting and moaning their pleasure, and hearing the slapping of my dad’s cock and my mom’s sloppy wet vagina made me horny as hell. Add to that my brother stroking his huge, rigid pole right in front of me….and I found myself getting really turned on. I could tell my pussy was getting wet and my nipples were starting to stiffen. I couldn’t help myself…I reached up with one hand and tweaked a nipple through my thin tank top, while sliding my other hand into my panties to rub my throbbing clit.

I must have moaned softly, because Corey suddenly looked over at me in surprise, and started to hide his hard-on by trying to shove it back inside his boxers….it wasn’t working.

I laughed softly, shushed him, then took my hand out of my panties and reached out to grab the shaft of his engorged penis…sliding my hand up to the firm, bulbous head, then down again to the thick, veiny base. Corey seemed surprised, but grateful, as I began running my hand up and down his stiff rod while standing slightly behind him, then we both returned out attention to the action taking place in our parents’ bedroom.

My father had picked up the pace, hammering his cock in and out of my mother’s pussy like a piston, while reaching underneath her chest to fondle and squeeze her dangling breasts. Every time he pinched her nipples, my mother let out a muffled squeal, pressing her face into her pillow to stifle the noise.
