I came home from a party a little drunk and, upon getting up to my room, could hear my parents having sex.

Instantly hard, I got close to the wall and started masturbating - listening to my mum's moans and my dad's grunts.

The hornier I got, the more I wanted them to know I was listening - so I began to moan. First it was subtle but then I got louder and louder.

Not long after, I came pretty hard with a loud "uhhhhh, mummy!" A little after that, they finished.

After about half an hour, i was horny again so I went into the bathroom and got a pair of my mum's dirty panties from the hamper.

I got right up to their door, sniffing her panties and pulling on my dick. Again, I began to moan.

"Uhhh, mummy! Daddy! Uhhh! I want to lick you both clean! I want to smell your assholes!"

To my surprise, I started to hear soft moans from my mum. Then my dad. Then the familiar creak of the bed. They were fucking again.

At that point, I lost my mind. I wrapped my mum's panties around my dick with one hand, and my fingers on the other went straight up my ass.

"Uhhh! Fuck her, daddy! Fuck her!"

My mum came pretty hard, it sounded like. Then me. Then my dad. But I still wasn't done.

I plunged my fingers into my ass, forcing another erection out of myself, and my moans continued.

"Mummy! Daddy! I need to taste you! I need your smell!"

The door opened up and my dad was standing their in his underwear, erect bulge on display. I glanced over to my mum who was under the blanket. I couldn't tell for sure, but it looked to me like she was masturbating.

I didn't stop. I just stared at my father's crotch and kept moaning until he calmly said, "I think that's enough."

He lead me to my room and lightly pushed me towards my bed, saying "try to sleep it off."

I just looked at him and said "I want to smell your dick." He said nothing and instead just turned around and started to leave. As he did this, I ran towards him and pushed my nose against his ass and inhaled slow and deep. He did nothing to stop this, whatsoever.

This lasted for a few seconds, but when I reached around to touch his dick, he grabbed my hand and lightly pushed me back into my room , before closing the door.

In my room, but against the connecting wall- I masturbated one last time, moaning as loud as before. After I came with a loud "daddy!" I practically passed out on my bed.

For the most part, our relationship didn't change much after that, although the loud masturbation is still a thing, and I always moan for them. They also start fucking after I start masturbating, quite a lot - but we never talk about it.

I do a lot less to cover up when I'm looking down my mum's top or staring at my dad's bulge, and I'm sure they notice but never say anything.

Only time my obsession with them was ever out in the open again was also when I was drunk, and they were still up. I grabbed some of mum's underwear and brought it down into the living room, sat on the sofa next to mum, and stared sniffing them and rubbing my dick through my jeans. My mum cleared her throat and my dad said, "maybe you want to take that upstairs."

I said, "maybe. Are you two coming up?"

My mum asked my dad, "did you want to go up to bed?" He did, and we all went up.

I tried to follow them into their room but my dad pushed me back, saying "let's not get carried away."

I stood by the door and the night went as many did.
