She tells you!

As you were making your coffee, you start thinking about your hot sister and girlfriend. They are still pretty good friends, and you know as a fact that Charlotte has been over at Sara's house many times. The way you recall it, your mom even made jokes about Charlotte basically living there. Not only does she have to know how Sara's family is... but she's also fine with it. How would she react if you'd just pull out your cock in front of her and jerk off?

You ponder on this thought as your coffee finally finishes pouring out of the machine. You take it and walk towards Charlotte. Did she know where he was last night?

Before you thought about it, you asked: "Do you know where I was last night?" Charlie raised an eyebrow but didn't look towards you.

"No, I don't, why?" She didn't seem interested in the slightest.

"Well... I was at Sara's house." This finally evoke a reaction from her. She looked up at you, eyes hopeful.

"Seriously? How was it?" Charlie seemed very curious.

"It was very..." You were searching for the correct word "...liberating" You smile as you say that last part.

Charlie grins like a little kid on Christmas. "So, is it fine with you if I would do something like that?"

You giggled awkwardly, "I mean... yeah, I don't mind" Your red head sister didn't waste a second. She simply pulled off her towel, exposing you to her bare chest and pussy. You did not expect this at all!

Without any further discussion, Charlie sat back down at the table and started mindlessly fingering her exposed pussy. "Omg, you know, I was excepting to be home alone today. I'm so horny, you see, I just spent last night masturbating to some **** porn and-" She takes her fingers out of her mouth and gives them a good suck before putting them back into her vagina. "- So I was so mad when I saw you. But this is really nice."

All this happened so fast, you could barely react to the sight of your naked sister masturbating in front of you. Just then, she looks up and sees how flustered you are.

"Don't worry, You can do the same. No judgment. Like at Sara's." That last part broke you. Suddenly none of this felt weird anymore. It was just like at Sara's. You pulled down your pants and exposed your cock to your sister.

Soon, both of you were masturbating while looking at each other. You didn't want to cum yet, Charlie on the other hand went to town. It wasn't long before she came and squirted all over the floor, some even reaching your legs.

Still orgasming, she looked you dead in the eye and said: "You better fuck me with that cock!"

Without thinking a second about it, you stand up and place your cock around your sister pussy. She starts moaning. "OOHhh, yes, Fuck me!"

With that, you start going at it. The faster you go, the more Charlie moans.

"Don't stop bro. AAHHhh Fuck me Fuck me Fuck me Fuck me." She's now moaning so loud that you fear the neighbors hearing.

Suddenly, your heart drops as you hear the front door close. Someone had caught you.
