Wear some of my older brothers clothes

I stood there dripping wet, towel half-wrapped around my waist, staring at the laundry basket my mom had left behind. The dream still clung to me. The voice’s words replayed clearly now: wear their clothes, and the body part that clothing covers becomes yours. Swap fully with a spell I somehow already knew.

Piled high were my mother’s things and Alice’s things, but my eyes locked on one item half-buried under everything else. A pair of my older brother Jake’s boxers and a soft, well-worn gray hoodie. Jake was twenty-two, lanky, permanent half-lidded eyes, the classic skater-stoner who never seemed to give a shit about anything. His clothes always smelled faintly of weed and cheap body spray.

My cock twitched under the towel. This was insane. But the dream had felt too real to ignore, and the thought of putting on his clothes made heat pool low in my stomach.

I locked the bathroom door quietly, then reached into the basket and pulled out Jake’s boxers. I dropped the towel and stepped out of my own underwear. My cock stood half-hard already. I slid his boxers up my legs. The moment the waistband settled around my hips, a sharp, electric tingle raced straight through my crotch and outward across my skin.

I watched in the mirror as my cock pulsed once, then thickened and lengthened. The shaft grew heavier, the head flared wider, and my balls dropped lower and fuller. It was no longer mine. It was Jake’s thicker, longer dick, already half-hard and heavy against the soft fabric. At the same time the tingle spread over my thighs and ass. The soft cotton of the boxers pressed against the skin there and rewrote it. My thighs filled out a little, becoming leaner but denser, the same shape as his from years of skating and doing nothing else. My ass rounded under the fabric, higher and firmer, the exact curve that filled out his jeans. Every place the underwear touched shifted until the lower half of my body matched his.

I gasped as the new weight settled between my legs, thicker and more substantial than what I had woken up with. My hips stayed mostly the same, but the heavy, sensitive cock now filling Jake’s boxers was completely his, and the thighs and ass underneath them belonged to him too.

I ran a shaking hand down and wrapped my fingers around it through the fabric. A jolt of pure pleasure shot up my spine. It felt bigger in my grip, hotter, and already leaking a little at the tip. When I squeezed, the new muscle in my thighs flexed under the boxers and my ass tightened in a way that felt foreign and right at the same time. I bit my lip hard to keep from moaning.

Next I grabbed his gray hoodie. Soft, oversized, still carrying his scent. I pulled it over my head. Instant pressure bloomed across my chest and shoulders. My shoulders broadened a little. My arms lengthened subtly. My chest stayed flat but the frame underneath shifted, becoming leaner and lazier, like it belonged to a twenty-two-year-old guy who never worked out but somehow stayed thin. The hoodie hung on me the same way it hung on him.

I stood in front of the mirror, breathing hard, thighs pressed together. Every small movement made the new, thicker cock rub against the soft fabric of Jake’s boxers while the reshaped thighs and ass shifted under the same material. The mix of his scent, the strange heavier dick between my legs, the solid new feel of his lower body, and the raw heat building in my gut made my knees weak.

I knew the spell without thinking. A short phrase rose in my mind. If I said it while wearing his clothes, the exchange could lock in permanently or reverse. I hadn’t decided yet. All I could think about was how good it already felt, how full and heavy Jake’s cock sat in his own boxers on my body, how completely the underwear had claimed my thighs and ass as his.

Footsteps in the hallway. Alice’s voice called out, “Mom? Did you start the laundry yet?”

I froze, heart slamming against my chest under Jake’s hoodie. The thick cock in his boxers twitched hard, a fresh bead of precum wetting the fabric. My new thighs tensed. My new ass clenched.

I could take the clothes off and reverse everything, or I could keep going.
