Incest Seduction/Keep Kim's shorts
From Create Your Own Story
"Well I don't think there's an awful lot you could do about it if I did, now is there?" you cockily reply.
Kim smiles at you boldly. "We'll see about that!"
Your sister lunges forward, her waist bumping up against your knees. She stretches her arms forward but you casually lift her shorts above your head. You have a substantial height advantage over her and as such a considerable reach advantage as well. She strains upward, clawing at your shoulders to gain additional height, but there's no way she can reach it unless she stands up, which is something you are now very interested in witnessing!
However, despite her teasing, it doesn't seem that she is ready to expose herself to you so willingly. She grabs onto one of your arms and tries to pull it downward but meets with little success. She laughs and slaps you playfully, begging for you to drop your arm, but this is all far too much fun. You decide to part your knees in an attempt to gain a glimpse between her legs. She reacts quickly, pushing herself forward into the front of the couch. She also gains a few inches because of that and once again begins straining upward towards her shorts, but she still doesn't have a hope of besting you.
"If that's all you've got you might as well give up now!"
Kim lower her hands to each of your thighs and glares at you with utter determination. But her expression quickly changes when she glances over your shoulder.
"Oh no..." she mutters.
Your heart skips in fear. Twisting your body around to look behind the couch you strangely feel Kim's hands latch onto each leg of your sweatpants. A feeling of dread washes over you the moment before your sweats are stripped down your legs by your sister. Of course, matching your sister, you also chose to forgo underwear this morning. She gasps watching your dick spring outwards as she lowers your pants as far as your knees before waiting for your reaction. You grab hold of your partially excited penis in an effort to retain some modesty but also refuse to lower the arm holding her shorts. You're too stubborn to let such cheap tactics succeed.
"Hey! That's not exactly fair!"
"Actually, it's perfectly fair!" Kim replies. "You took mine, so I'll take yours! Unless you wanted to agree to a trade?"
You can't help but smirk at this strange standoff. "Yeah? And what if I refuse?"
Kim shrugs. "Then I guess I'll have to wear your sweats instead." She threatens you further by inching your pants past your knees. "I'm sure I can fit these, but good luck getting into my shorts!"
It doesn't seem like you have a lot of options.
That's probably enough. Best to end this peacefully.
You can't just let her get the upper hand! Reach down and grab onto her shirt!
