Yeji and I were best friends and have been for forever. Today we went swimming together at a water park, the sun beating down on our shoulders as we raced down twisting water slides and screamed with laughter. The chlorine stung my eyes but we didn't care, spending hours playing in the wave pool until our fingers pruned. When we finally dragged ourselves home, neither of us wanted to use the grimy public showers at the park. The car ride home smelled like chlorine and sunscreen, our damp swimsuits sticking uncomfortably to our skin.

At my place, the bathroom tiles felt cool against my feet as I turned on the shower. Steam quickly fogged the mirror while the sound of rushing water filled the small space. "We should shower together to save water," Yeji had said with a playful grin, but there was something in her eyes I couldn't quite place. I agreed, thinking nothing of it - we'd changed in front of each other hundreds of times before.

The hot water felt amazing against my tired muscles as I stepped under the spray. I reached for my shampoo, my wet hair cascading down my back, when suddenly I felt warm hands wrap around my waist. My breath caught in my throat as Yeji's body pressed gently against mine from behind. Her wet hair tickled the back of my neck and her warm breath sent shivers down my spine. "Mm, I didn't know you looked so good.." she whispered, her lips almost touching my ear as her finger slowly teased my nipple.
