Oh, brother... Hers.

With everything that you've been through lately, you NEVER would have expected that your sister would be naked as a newborn in front of you.

Yet, there she was...

You realize that it's only been a couple of days since you and she were together for her giving you a blowjob. And you've been going along with it pretty well, for a while. But somehow, you had that feeling things were going to be a little different than usual when your sister took slow strides, accentuating how her hips smoothly rocked from side to side. "Like what you see, brother...?" she purred softly.

Unfortunately, the erection in your pants was answering that question for her. You swear she giggled like a schoolgirl, a bit high-pitched and playful. It took that giggling to snap you out of your trance, seeing your sister in a new perverted light. "Um... Listen. Something's been going on at school, and--"

"I'm listening..." she hummed softly, seeming to assert just the opposite while unbuckling your belt and unzipping your jeans to have them drop to the floor. You know your sister had become really cock-obsessed about you, but... She was rubbing her face on the bulge in your underwear!

Did you really wake up from your nap...?

She took deep breaths in the meantime, roaming her right hand on one side of your hard-on. "Right. So, uh... There's this girl, Tiffany." All you got was an 'Uh-huh' from Shelly while she licked your dick through the fabric, and suckled on your balls.

Geez! What a tease this girl was, pleasing your dick... IT WAS YOUR SISTER, FOR PETE'S SAKE! "She broke up with-- ahh! Her boyfriend. A soccer star..." you sigh. You lean your head back just as she slid your boxers off, and she watched your cock spring out, nice and erect in her face.

"Oooh..." she cooed, like reacquainting with an past lover. "Hel-LO there."

"Shelly, come on," you argue.

"Yeah, yeah. I hear you." She starts jerking you off with one hand to keep you hard as iron. "Cheerleader captain broke up with the Soccer star." She then wasted no time in gulping your entire meat down her throat, gagging while deepthroating you.

"How did you know about it?" you asked kinda dumbly, reeling from her warm mouth and expertise.

Her head bobbed up and down and you heard the sounds of her gagging on your cock, stroking you off as well. She pulled up, taking a breath before answering. "Think I don't pay attention to your Facebook posts?" Shelly combed all of her hair to one side before she continued blowing you so well.

As you watched her completely engulf your whole cock, and alternate with jerking you off with both hands, part of you begins wondering what would have happened if you had known that you had gone into your sister's dream the first time.

Could she have been more than just a blowjob slut for you?

'Hold ON! This is still your SISTER, you pervert!' you scold yourself. 'This has already gone too far.' But any other sound thoughts you had about what to do with her afterwards were gone as she was bringing you closer and closer to shooting your seed. For the umpteenth time this week!

At least two separate times, she spit on your cock and used it to slick it up before going back to kissing along its length and deepthroating you again and again. Your burning desire races through your veins, having you grope the back of Shelly's head and gag her some more while you brought yourself closer to an orgasm.

"I'm gonna cum! You want my cum? Huh?" You just talked dirty to her, wanting to blow in her mouth.

Shelly really seemed to enjoy that, purring sexually. "Mm-hmm! Mm-hmm!" she answered.

"That's right..." you pant heavily. "You want my cum. You love my cum. You love sucking my cock. You're my dirty sister. A dirty, cock-worshipping, cock-obsessed slut of a sister...!" Shelly really took every word you said to heart, and by the time you finally orgasmed, shooting rope after rope of your semen into her mouth and throat, she had an orgasm herself, rolling her eyes back so far.

You were so exhausted, that you just fell back on the couch with your deflated manhood popping out loudly.

Your 'slut of a sister' laid there after swallowing so much of your cum, letting a little leak out the side of her mouth and onto the floor; you really fell limp on the couch when you passed out in no time.
