Chapter 4: Secret Nights While Mom Sleeps Down the Hall

Mom shuffled into the kitchen the next morning, still groggy from her wine run into town, robe slipping off one shoulder as she poured coffee and complained about her sore back again. Breakfast was simple eggs and toast, the three of us around the table like any normal family. She chattered about a possible hike later, voice raspy, but her eyes barely focused. Mark and I locked eyes across the plates, the secret heat between us crackling like static. Under the table my bare foot crept up his calf, toes tracing higher until they pressed against the thickening ridge in his pants. He stayed perfectly still, jaw relaxed while nodding at Mom’s complaints, but the muscle in his thigh jumped under my sole. I wore his oversized flannel shirt as pajamas again, the soft worn cotton draping my bare body, hem skimming my thighs. Mom glanced over and smiled sleepily. “That’s so cute, Riley, still stealing your stepdad’s shirts like when you were little.” The words made my cheeks burn, but the insane tension only grew—knowing what waited after she crashed tonight.

The day dragged in sweet torture, hiking talk turning to plans for dinner, Mom rubbing her back and promising to turn in early. Secret looks passed between Mark and me, loaded with promise. By evening the air hummed with it.

Mom downed her third glass by nine and passed out hard, snoring rumbling through the thin loft walls like distant thunder. My phone glowed in the dark. I typed fast: my room now. Seconds later the door creaked open. Mark slipped inside, closing it silently, moonlight filtering through the window casting silver across his bare chest. I stood by the full-length mirror in the corner of the loft, heart hammering. “Watch us, Daddy,” I whispered, turning to face the reflection. He came up behind me, hands sliding under the flannel to cup my breasts, thumbs circling nipples already hard as pebbles.

I pushed the shirt off my shoulders, letting it pool at my feet. Naked now, I backed against him, feeling his cock throb hot against my ass through his shorts. I tugged them down, freeing the thick length. Then I bent slightly, guiding him to my entrance and sank back in reverse cowgirl, facing the mirror so we both could see everything. The sight hit like lightning—my body lowering onto him, his veined shaft disappearing inch by inch into my slick folds, my tits swaying, his hands gripping my hips. I started bouncing, slow at first, watching my own face twist in pleasure, lips parted, eyes glassy. The reflection doubled the thrill, like fucking two versions of us at once.
