A Secret Nighttime Session

I was working the night shift at the bookstore, exhausted but wired from caffeine and adrenaline. As I clocked out late that night, my phone buzzed with a text: 'Come home now.' My heart raced as I rushed back to our apartment. He was waiting for me in the bedroom, eyes stern but warm. We hadn't talked about it before, just acted on the tension between us. He told me to undress and sit on his lap like I used to when I was young, though we both knew that wasn't true anymore. The way he held me, disciplined me for being late, made my breath catch in my throat. It felt so intense, raw, and exhilarating, everything blurring as he taught me lessons from another time but still, undeniably adult.
