Chapter 1: The Discovery

I never meant for any of this to happen. I’m Sarah, forty-two, married to Mark for twenty one years, and Alex’s mom. Just a normal curvy mom who spends her days keeping the house together while my husband flies off on another business trip. That afternoon the sun slanted through the blinds in Alex’s room, the air thick with that boyish mix of cheap deodorant and teenage sweat that clings to everything he touches. Gym shorts tossed on the floor, posters of bands I don’t recognize curling at the edges, his laptop still open to some half-finished assignment. I was in my usual cleaning uniform—black yoga pants that hugged my wide hips and a loose white tank top that kept slipping off one shoulder—bending over the vacuum to reach under his bed.

My fingers brushed something soft. I pulled out three pairs of my own panties. Black lace. The ones I’d worn last Tuesday, the ones that had vanished from the laundry basket days ago. My heart slammed to a stop. Each pair had stiff, yellowed crusty patches right on the gusset—dried cum, no question. Thick, flaky streaks that caught the light like secret little confessions. These weren’t random. These were mine. My son had been using them.

Oh God, Alex ... what have you done? The thought hit like ice water, but underneath it something hotter stirred low in my belly. I should have dropped them, burned them, screamed. Instead I sat on the edge of his unmade bed, the mattress still warm from where he’d slept, and held the first pair up to the window. The crust caught the sunlight, almost glittering. My nipples tightened instantly against the thin tank, pressing hard enough that I felt the cool air through the fabric. My thighs squeezed together without thinking, yoga pants suddenly too tight, the seam rubbing right where I was already getting slick.

This is my nineteen-year-old son’s cum. I’m his mother. Mark would die if he knew. The guilt crashed over me so hard my eyes stung, but my body betrayed me. My pussy flooded, a warm gush that soaked straight through my own panties. I could smell it—my own arousal mixing with the faint musk still clinging to the lace. Salty. Young. Male. Like nothing I’d ever breathed before. My hand trembled as I brought the stiff gusset to my nose and inhaled.
