She Wants you to Seduce Him

"Let's trick him and have you seduce him. Then after, I'll bust in and surprise him and see how he reacts," Zoe says with a giggle as she thinks of the prank she has planned.

The two of you lay out your plans and both of you get dressed again after Zoe calls Sam and tells him to come on over. You're both downstairs when he arrives. Zoe gives him a big kiss and then excuses herself to go "get ready" leaving him waiting for her. You can't help but look him over, his large muscular six-foot frame, wavy brown hair and deep blue eyes. Hanging out near him you make sure to flaunt some of your assets, your tits without a bra under your white tank top, and your ample ass in tight short jeans. You can't help but feel excited about what is coming as you catch him eyeing you out of the corner of your eyes several times and you swear his crotch looks just a little bit bigger.

Finally ready to spring the trap, you turn to Sam and ask, "Can you help me with something in the garage, Sam?" Quickly agreeing, you both head out to the secluded garage. Pointing to a few bins in the overhead storage, you move over a short step stool and say, "Can you grab those two and get them down for me? They're pretty full of Legos and little toys, so don't drop them or we'll be out here picking them up for an hour." These bins were a known issue to your family and if you didn't take them down the right way, they would get stuck halfway and you couldn't push the bins back up or get them down with spilling them or someone else's help.

"Sure thing, Alana," Sam says, eager to help as he steps up on the stool, bringing his crotch right to chin level. As expected, he tries to bring both bins down at the same time the wrong way and they get stuck. "Uh, I think they're stuck," Sam says as he desperately tries to push and pull them free without the bins popping open. "I think I need your help."

"I thought you'd never ask," You say as you step closer to him and reach up to the leather belt around his waist as you continue, "I heard you had a birthday coming up, so I wanted to give you your present now."

"The fuck are you doing, Alana," Sam burst out. He looked down at you while you met his gaze confidently as you unzipped his jeans. As you drop his jeans to his ankles and pull his member out of his shorts, you're pleasantly surprised at the size of his semi hard cock. Leaning in you, take a deep breath through your nose as you inhale his musk. "You can't do this, your sister... uuuuh," Sam trailed off as you popped the head of his cock into your mouth and begin alternating sucking and licking it.

After a moment, his arms began to drop as you got ready to try and stop you, popping his now hardened 11 inch, thick, cock out of your mouth, you warn him, "Don't let those bins drop or she'll definitely know something's up. She won't know anyway, this is just a birthday present." You finish and immediately throw your mouth back around his rod. Luckily, he hasn't dropped the bins as you begin forcing inch after slobbery inch of his cock into your mouth and into your throat. He can't help but groan in response as you bury the entire length and push until your nose is pushed into his trimmed pubes and you can feel his balls on your chin. You feel his body relaxing as the sense of panic is override by the sheer pleasure of his fuck stick being fully throated.

Now that he's given up fighting you, you begin to fuck your own face with his cock, moving your head back and forth. Pulling out the entire length of his cock, you slam your head forward impaling yourself again and again on him. As forceful as you are, your gag reflex doesn't even have a chance to really respond as you're pummeling your throat with his shaft. Thick globs of spit and pre-cum pour out of your mouth as you continue to pick up the pace and his hips unconsciously move in rhythm with your movements.

After about 3 minutes of this, you feel his balls tighten in warning and you grab each ass check and hold him in place, his member completely encased in your mouth and throat as he begins pouring shot after shot of cum down into your stomach. Honestly, you're impressed at the sheer quantity of ejaculate that roars out of him as you keep **** yourself on his meat. Which the twitching of his cock and the stream of goop finally stop, you pull your mouth off him and look up at him while you start to stroke him.

Sam is looking down at you with an amazed and satisfied look on his face as you firmly slap his still firm shaft on the side of your face seductively. "How was that for a birthday present?" You ask with a wicked smile. "Everything a blowjob should be?"

Giving a sigh of relief, he says, "It was fucking incredible, probably the best I've ever had. I've never had anyone gag on my cock quite like that before." With a twinkle in your eye, you wink at him before giving his cock head a small kiss and stepping up on the stool and helping him pull the bins back down. He pulls his shorts and pants back up and as he buckles them, he asks you, "What are we going to tell Zoe?"

You give him a big smile and shrug a bit, leaving it up to him. Part of you wonders if this was all a test that your sister is running on her boyfriend, but the other part of you is just having fun with this gorgeous man.
