Prank Roman with his sister's body

I suddenly had an evil idea in my new head.

I step out of the room and walk over to Roman’s, slightly lowering the neck of my shirt, exposing my chest even more. I then do the same to my shorts, sliding them just above my crotch. After making my adjustments, I turn the doorknob and walk right into his room, once again surprising him.

“Oh, it’s just you Katelyn,” he replies, “What do you want? And why can’t you ever knock?”

“Oh, gee, little bro,” I say, bringing a finger to my lips and swaying my hips, feigning innocence, “You’re right. That’s not a good thing for me to do, is it? I’m sorry. You wanna punish me for being so inconsiderate?”

His jaw just drops. He’s utterly speechless. He doesn’t even know what to think. He’s just sitting there, staring at me. Just like I thought he would be. Serves you right, you bastard.

“Wh-what’s going on with you?” he says, ogling at my body and the alterations I’ve made with my clothes,

I giggle before standing in front of him, saying in a ditsy tone,

“I’ve just been thinking about the way I’ve been treating you and your super awesome, intimidatingly smart, funny, cool, and outlandishly handsome friend, Chad all this time. I’m such a stupid fucking bitch who just mooches off of you. Surely, you can find it in your heart to forgive me for being so dumb. Ooor~”

I bring my hands to his shoulders, flipping my hair as I straddle his lap, continuing with a sultry tone,

“Maybe you can come up with a way for me to repay you for all of it.”

He stutters, tripping over his words, making me giggle. I then feel something growing in between us. I giggle before slowly grinding my hips on his clothed growing shaft.

“Ooo,” I start as I feel him pressing against me, “Looks like you have an idea as to how I’m supposed to apologize. You want me to show you how sorry I am, little brother?”

He, again, tries uttering something, but shock and my intimidation are preventing anything from coming out. So, using my context clues, I deduce that he’s trying to say “Yes”.

Since I am in Katelyn's body, I take on her sexual attraction on top of my own. I may not like taking dick myself, but her body certainly does. Besides after experiencing sex as my sister, I starting to like the pleasures of the female body. It like being on autopilot, I just do what is in her interest. Now, being the caring big sister I am, I decide to accommodate his subliminal demands. I chuckle before planting a kiss on his nose and maneuvering on the floor in front of him. I then bring a hand to his covered dick, gently rubbing it.

I stop a bit to pause. This should be enough proof for Roman. I should stop. I'm I really going to fuck my best friend with his sister's body?
