19 year old bisexual girl

Reflected back at me I see my slender legs holding up my petite 5 foot 7 form. I've never been one for working out but I do go running every now and then as I like to stay in shape, I'm pretty proud of my sexy little body. Most girls say they want big breasts but I'm quite happy with what I have, sure they aren't huge but I think C-cups suit me well. As my gaze travels upward I see my bright blue eyes looking back at me ready for my late night spy mission. I grab a scrunchy off my nightstand to quickly tie up my long blonde hair, don't want it getting in the way for this, then as quietly as I can I slowly open my door.

*Slap, clap, clap, slap* "Oh fuck yes baby ride that fucking cock!" "Yes! Yes you're so fucking big I can feel you hitting my deepest parts!" *Slap, slap*

As soon as I get it open I see the light pouring out of the their room and the sounds grow louder, my parents must think their room is soundproof going at it like this.

I creep my way over to their door and realize why it is so loud. The door isn't fully shut! I slowly push it just enough to get a peek, *creek*, suddenly I freeze hoping they didn't hear. *Slap, slap* "yeah fucking grind that cock!" "...Phew I'm safe" I whispered.

Reaching down I feel my soft wet pussy now completely soaked from the excitement, the thought of being caught spurring me on and fueling my arousal. As I start to gently rub myself I peer in though the now cracked door and see my mom on top of my dad riding away like she cant get enough, easily taking his huge member into her glistening slit. As I watch I start to pleasure myself, thoroughly teasing my clit with my thumb while I let my fingers wonder into my waiting hole.

The noises slow down and as I peer in I see they are changing positions "OK time to really let me have it daddy" my mom said as she got down on all fours wiggling her ass in the air. "Fuck you are such a sexy little girl, get ready because daddy is about to fill you up!" *Daddy?* I thought. I've been masturbating to my parents fucking for as long as i could remember but they've never used that before. I push the door a little more to try and get a better look, and see they are now both facing away from the door with my dad fucking my mom with all he's got. Just then I see that my mom's hair is blonde, *when did she dye it? Fuck it I don't care she looks so hot right now*

I can see everything clearly now and am rubbing myself furiously not worrying about making noise as i know it'll be drowned out by all the racket they are making. I lay down on my side so I can see though the door while giving myself more access as I slide my other hand down to tease my ass. *Slap, slap, slap* the sounds are getting louder as my dad is really putting his all into fucking my mom "Ahhhh FUCK YES DADDY I'M GONNA..." my mom screams as she approaches her climax. "Mmm yeah baby you want me to fill that tight little cunt up?" I'm right on the edge having never seen such an erotic display before, my jealousy for not being the one getting it pangs in my chest for a moment as I bring myself to the brink, *I wanna cum with them! I wanna imagine that he's filling me up so bad.*

"Mmmm fuck! Alice take all of your daddys hot cum!" "Ahhh yes daddy fill your daughter up!!!" *Mmmmm fuuuuuck!!* We all come together and the light goes out I grab a towel and quickly wipe up the mess I made as I quietly scurry away to my room. I get in bed and be as quiet as possible as my thoughts race. *Mom said "fill your 'daughter' up" and dad even screamed my name does that mean...* suddenly I hear footsteps at my door and quickly close my eyes and pretend to be asleep as I hear my door creek open.
