What's the harm?

"Sure," you say, reaching down your pants and pulling your dick out from under her face. Before you can release it from your hand she's done 3 full bobs on the length that extends from your fist. The moment you let go the remaining inches slide easily down her tight velvet throat. It feels amazing. You're fully erect almost instantly.

"OOOooohhh shiiiit."

She begins a pattern of rapidly swirling her tongue around the top, teasing it along the bottom of the shaft as it glides into her throat, sticking it out to juggle your balls while still holding you deep, then leaving her tongue out and curling it upwards to tease your shaft from the outside on her way to repeating the process.

You watch for a moment, then attempt to concentrate on the form in your hand.

I'm here for my sister, I'm here for my sister, you think trying to remind yourself that she needs your load. This brings your sister's gorgeous round ass to your mind as the redhead finishes sliding down your pole and begins to lick your balls again.

Your eyes snap open and you attempt to distract yourself again with the form. You start writing your name as the redhead begins cutting out the flourishes and picking up the pace. Christ, she's too good, you think. I'm here for my sister, I'm here for my sister.... Your mind flashes to a time you saw your sister bending over to pull on a pair of panties on when she didn't know you were behind her. Her beautiful pink pussy gently opening for you underneath a gorgeous puckered assho...

You realize you're passing the point of no return and attempt to pull the redhead off your dick by her hair. Too late, the first shot fills her mouth as you pull the rest free.

"I'm here for my sister!" You blurt out as you begin to plaster the stranger's face with jet after jet of your cum, still holding her tightly by the hair. She looks up at you sadly as your jets begin to slow.

"Yo siddahs in a comah?" The redhead asks around the part of your load that made it to her mouth. You nod weakly as your last jet hits her in a tear filled eye. She suddenly smiles at you with one eye as you shake the last dribbles on her tits.

"Awl maag shu she geds dis" The redheads says. As she stands you wipe the remaining cum still clinging to your hand on one tremendous fishnet covered tit as it passes. Don't wanna miss any.

You roll your head over lazily and watch as the redhead approaches the receptionist, who is now being plowed from behind by a janitor. The redhead spits in a cup and the receptionist begins licking the redhead's face, much to the janitor's delight. The receptionist spits it into a cup, licks her face a couple more times, spits again, they exchange a few more words, and the redhead begins to walk way.

The redhead notices the cum still clinging to her tits and starts to clean it off with her fingers, popping them into her mouth as she goes out of sight. You dreamily look back over at the receptionist in time to see her down the cup with one gulp.

What the fuck.

Your head rolls back down and you look at your now limp dick. How are you supposed to help your sister now? You look at the form simply containing the letter "B" followed by a long dark line.

You weigh your options.
