Back home for a swim plus a game

“I honestly think we could head back home and maybe go for a swim since it’s such a nice day,” you say as you were unsure if that was a good suggestion. “Maybe even catch some rays since it’s not too hot out yet.”

Your sister smiled and said, “I like that idea, bro. I honestly haven’t had much time to catch some rays since coming back home and it’s honestly boring to do it by myself.” She begins to pull away from the curb and leaves the school quickly out of sight. She lights up with excitement as she says, “I have an idea of how to spice things up a bit. You have to agree to my conditions right now and NO QUESTIONS ALLOWED!” She extends a hand and asks, “Shake on it?”

You don’t even hesitate and offer her a hand, “Just know you are going down, sis. Bring it on!!!” She chortles as it causes her tits to bounce around freely in her top. You giggle bit as you stare at the transformation of a sister. You can’t help but notice she is really beautiful…but she’s still your half sister, dummy.

She stares at you with a sly grin and says, “Alright the game is simple it’s rock paper scissors but strip style. Winner chooses what comes off.” You feel like you have a bit on an advantage but you know it’s a game of luck so you get your hand ready as she says, “Alright! Rock…paper…scissors…shoot!” You look down and see that your rock beats her scissors as she says, “Darn! I’ll get you next time. So what comes off, bro?”

You think and say, “Let’s do your top. Might as well get some start tanning them a bit.” You both giggle as she quickly takes her top off and throws it in the back. You realize the mistake you made as her tits are now completely visible and a distraction. You call out, “Rock…paper…scissors…” but are too mesmerized by her naked, bouncing tits and lose focus as you bounce a rock up and down.

She notices that you are distracted and finishes saying, “Shoot!” Her paper beats your rock and you realize exposing her tits has put you at a disadvantage. “Alright bro! Off with those boxers.” You hesitate because you gotta take off your shorts all the way and then expose your engorged naked cock to your sister. You thought about fighting it but she had her tits out so you weren’t going to be a poor sport about this. You slide your shorts down your legs and pull your legs out.

Your sister can see your dick bouncing around in your boxers and begging for freedom. You grab the waist band and pull down to catch it as it bounces free from its constraints. She is glued to the size of it as she hadn’t seen it besides under my clothes. “You can pull your pants back on since I only said your boxers.”

You use this to your advantage since you are both distracted and say, “I’ll keep them off for now since I might just lose them in this next round.” You both are clearly distracted by the now uncovered private parts of the other. You are both so distracted that you both threw rock twice as you are distracted by her tits and she is distracted by your dick.

The third time has her winning and she says with a pant, “Off with the shirt!”, which kept you surprised since your pants were still off. “ You toss your shirt and boxers in the back as you are naked beside your shoes. You gotta admit it was pretty hot sitting naked in your sister’s car as your sister ate up every inch of your naked body. You could see you were almost home and the next game would decide who was walking out of the car naked.

You both get ready and you feel like you can win considering you are naked and her tits have been out for a while. She changes up the game though and slips off her skirt as is as naked as you are. “I’m just getting ready to lose my skirt as well since you haven’t put your pants back on. Fair is fair, bro,” she says with a wink knowing you can’t resist her pussy being completely exposed.

You try to focus but your pre-cum and spasming erection indicate you are doing a horrible job. You both call out, “Rock-paper-scissors-shoot!” You see that you both have paper for a tie and then do it again “Rock-paper-scissors-shoot!” It ends in another tie as you get ready to say it one more time “Rock-paper-scissors…!” She grabs for your cock and plays with the tip that causes you to throw paper instead of rock as she throws out scissors.

You groan as her hand plays with it and says, “I win! Toss your shoes in the back, bro!” You were surprised as you get to keep your shorts but she grabs them as well as her skirt and shoes. She tosses everything in the back and says, “We both technically cheated with nudity so the only punishment is we both go to the back nude without going inside. Remember we shook on it!”

You look at her and stare at her delicious naked tits to her shaved pussy lips and say, “Fair is fair!”
