A late night request

I drop Colette off at her house after dinner, then return home with Kelly. I follow her inside and up the stairs in silence, passing Mom in the kitchen with a wave. I turn to go into my room, but Kelly grabs my hand. "Hey, do you think you could help me with something before you disappear?"

"Of course," I answer.

She drags me into her room, and I am again assaulted by the pink and lace and whiteness of her decor. She closes the door behind her and gently pushes me onto the bed, then turns to face away. I freeze for a moment, confused, until she runs a hand through her hair and pulls it over her shoulder, revealing the zipper of her cheerleader outfit to me. Kelly looks over her shoulder at me with a demure, cerulean gaze.

"Can you unzip me? It's a little... tight after dinner."

"Sure," I agree and grab the zipper with my right hand. The zipper is plastic and the fabric of the uniform is cheap, rough cotton. I try to tug at it, but I realize Kelly isn't lying. It is tight, and the zipper won't budge. "I can't get it to move," I murmur. I try to scrunch the zipper to give it slack, then **** it with my other hand. I try pulling the fabric and pushing the fabric. I have Kelly sit down beside me on the bed and lean forward, trying to create a new angle. "Nothing," I say, sighing. "It won't budge."

Kelly lets out a loud breath and flings herself back onto her mattress. She looks down her nose at me and sighs. "This blows," Kelly murmurs, looking away again. "I can't believe I got too fat to get this thing off."

"I wouldn't go saying that," I say. My eyes wander over her pale, toned thighs next to me, and I feel desire stirring within me at the sight of her sinking into her comforter. "The zipper is poor quality. It's way too small and impossible to grasp." I **** myself to look around the room for ideas. "Do you have any oil or anything I could put on it to try and loosen it? I think it might be stuck on the fabric."

Kelly lays silently for a moment before answering. "Yes... I have something. Just... don't judge?"

"I never would," I answer, immediately, and she nods.

"Fine, okay. Give me a second."

Kelly slides over the edge of her bed and squats down. I watch her blonde curls tumble around her again as she pulls a box from underneath her bed frame and opens it. The sound of rustling bottles and cloth echoes in the room. Finally, she pushes it back under the bed and tosses me a plastic, sticky bottle.

I read the front of the bottle. "Discover: personal lubricant." Oh. Ohhh. My mind is immediately assaulted by thoughts of what my younger sister has done with this bottle, and I can't help but wonder what is else in the box she just put away.

By the time I look up, Kelly is standing in front of me again with beet-red cheeks. "It's not a big deal, Kelly. Everyone uses this kind of thing." I turn the bottle over in my hands. It's half empty. She's certainly been using it.

"Just... don't talk about it."

I nod and squirt some of the lube onto my finger. Kelly turns away and presents the zipper to me again, but I quickly realize that I can't get the lube into the zipper at this angle. "Can you lay down on the bed? I need to squirt the lube directly into the hole, I think."

"Phrasing," she mutters, but she follows my request. I look at her laying there, for a moment, and my desire punches at me again. I feel my cock harden in my jeans. Fuck, I need to get out of here before I do something stupid. My sober mind recognizes that this situation is bizarre, but I am unable to focus on much beyond that.

I quickly sit beside her and drip some of the lube into the zipper, working it back and forth until it releases in silence. Kelly sighs as the fabric relaxes around her. "Finally!" she says, rolling back over onto her back. She smiles up at me, her cheeks still red and the scene of strawberries wafting up from her sheets. "Thank you, Dom. I did not want to have to cut this thing open with a pair of scissors."

"I wouldn't haven't minded that," I answer, unthinkingly. My cock continues to pulse in my jeans at the thought of helping her out of the cheerleading outfit, and I sigh.

Kelly's breath deepens for a moment. "Dom..." she murmurs. Her eyes down, and I realize what I said. Her eyebrows narrow, and I track her gaze to the massive indention in my pants. I would try to hide it, but it is physically impossible these days.

"Shit, Kelly, I didn't--."

She raises one finger to my lips to quiet me, and I see a light building in her eyes. She slides out of bed beside me, gently pushing me onto the mattress again to ensure I do not follow, and walks to her closet across the room. "Stay," she says, as she demurely looks over her shoulder at me. I look at her with a mixture of confusion and understanding. I don't know what is about to happen, but I simultaneously do.

Her closet door opens, and she reaches for an old white t-shirt. A Lynard Skynard logo is painted on the front. I watch the white and red cheerleader outfit strain and spread against her body, revealing her bare back to me. Her skin is as smooth and pale as I expect, and I am struck by the thought that she has exceptionally clear skin for someone so active.

The sound of her dresser drawer is accompanied by a pair of cotton gymnastics shorts.

Kelly tosses both pieces of clothing onto the desk next to her closet, already littered with school books, paper, and makeup, and looks over her shoulder at me one final time. My breath freezes as our eyes meet and her hands tug at the shoulders of her cheerleading outfit. Despite my difficulty in unzipping it, it readily falls to the floor, pooling around her feet with a soft thud and exposing my sister's beauty to me in a single moment.

"Oh my," I stutter, absolutely stunned by the sight of my sister standing in front of me in only a nude-colored thong, the material hardly visible against her skin. Her ass is perfectly round, and my mouth salivate as she presses her hand into it and tugs it for me. Her French-manicured nails dig into the flesh and form shadowed valleys that I want to explore more than anything. Absent-mindedly, I rub my cock through my pants, until I realize what I am doing and **** myself to stop.

The view only lasts a few wonderful seconds and ends with the sight of her glorious ass bending over to pull her shorts on. "Kelly," I say, and I fight the urge welling within me. The urge to go to her, hold her, fuck her. My cock seethes from within my pants, eager to be with her.

She ignores me, continuing my **** in silence. The shorts meet her waist, doing little to hide her curves but a lot to hide the satin, pale flesh I so feverishly want to touch. Her fingers roll the waistband over once, then twice, drawing the shorts up into her ass and granting me a seductive view of her ass that is somehow more teasing than when she wore no shorts at all.

She grabs the t-shirt and pulls it over her head, slightly twisting her body in the process so that I can catch a glimpse of her breast. Her nipple is hard and pink, and the sight of it sends another shiver through my body.

"Kelly," I murmur again, my hand reaching out wards her despite my best efforts otherwise.

"Dom," she says, finally turning back to me. A warm smile is on her lips, and the blush on her cheeks matches the strawberry scent permeating from her sheets. She doesn't sit back down or try to touch me. But she does continue smiling. Looking at me. Her eyes roam down my body and focus on my throbbing erection. Pleased.

I cover myself with a sharp jerk, apologizing. "Sorry, Kelly, I didn't--."

"Shh," she murmurs, holding a finger to her lip. "It's okay, Dom." Kelly winks. "I'd rather see that than nothing at all. But... for now... I think I should be alone." She walks to her door and opens it, a demure expression on her normally free face.

"Okay, Kelly. I love you," I say, as I walk past her and into the hallway.

She looks at me through the doorway as I go. "I love you too, Dom," she answers with a smile. Before I can blink, my sister darts forward and plants a soft kiss on my lips for one second, then two. I raise my hands to her waist to enjoy the moment, but she is already gone. The door closes behind me with a soft thud.
