Family secret

So, it was my 18 birthday and my parent and 20 year old sister, Jane, took me out for dinner. Jane seemed especially amped up and giddy for some reason. I guess she was excited about me turning 18.

After dinner we went home and I played video games for a couple of hours and went up to bed.

I grabbed my laptop and turned on some porn to masterbate to before I went to sleep.

Not long after I started Jane comes bouncing into my room in a tiny see through nighty. Her tits were bouncing up and down and her nipples looked like they were going to poke through the thin material. This just my dick a lot harder.

I tried to cover up but she said “Don’t bother, I’ve got a family secret to tell you”. And followed up with “wow you’ve got a huge cock”.

I just sat there staring at her tits while the porn playing and a death grip on my throbbing dick.

“What’s the big secret” I ask.

“The big secret is that I’ve been fucking mom and dad for two years now and since you are 18 now you get to join in.” She said with a huge grin. “And since I won the coin toss with mom I get to be the one to tell you and be the first to fuck you. I’ve been waiting two years for this.”

“Wait, so you’ve been having sex with dad since you were 18.”

“Yeah, and mom too and sometimes all three of us together. And now you get to join in.”

Now, I’m not gonna lie. Jane is hot and so is my mom and I’ve fantasized about fucking them a lot. But this was a bit surreal.

I lay there dumbfounded as she straddled my hips and guided my cock into her tight dripping pussy.

“Oh my god your cock is massive.” She said with groan as she slowly lowered herself balls deep into her pussy.

Once she got accustomed to my size she started grinding and riding. Her tits we’re swinging and swaying right in my face so I grabbed one in each hand and pressed my face between them licking every square inch. I started sucking her nipples which made her moan and she came all over my dick.

I told her I was about to cum and she lay down on me her tits smashed against my chest and whispered for me to cum inside her. At that I lost it and unleashed a huge load of cum deep into her pussy.

We lay there for a few minutes to catch our breath and I could feel my cum flowing from her pussy and onto my cock and balls. She promptly turned around and cleaned up every drop of cum with her tongue and swallowed it.

With that she got up kissed me on the lips and left to report in to mom and dad I guess
