Memorial Day, 11:47 PM – Lake Harmony
Your wife Samantha is asleep upstairs in her ivory silk sleep set, noise-canceling headphones over her ears.
You step onto the dock for air — and see Kimberly (22, your sister-in-law) on the steps.
She’s in Samantha’s old sailing hoodie, faded navy cotton unzipped over a lace bralette. Yoga pants hug her ass; the hem barely covers her thighs. Cool lake air raises goosebumps on bare skin. Her silver nose stud glints.

“Couldn’t sleep either?” she whispers, voice soft. “Sam’s been snoring since 10… but you always did have trouble winding down after these weekends.” She pats the warm wooden step beside her. “Come sit with me? It’s been forever since we really caught up. How are things with you and Sam lately?”
