I came home early from my shift at the diner and the house was dead quiet. Mom was supposed to be at work until six, so I figured I had the place to myself. I headed straight for her bedroom to borrow a pair of heels for a date later.

The closet door was half open and something caught my eye on the top shelf behind a stack of sweaters. It was a box. Not just any box. The kind you hide things in.
I pulled it down, already knowing I shouldn't. Inside was this massive dildo. Thick, veiny, flesh-colored silicone that had to be ten inches long and thick as my wrist. A suction cup base stuck out from the bottom. My stomach flipped. Mom owned this thing. My own mother had a huge fake cock she fucked herself with.
I should have put it back. Instead I wrapped my fingers around it. The weight felt obscene in my hand. I pictured Mom on her back, legs spread, working this monster into her wet pussy. My own cunt clenched at the thought. I was already wet, nipples tight against my bra.
I carried it to her bed and sat down. The sheets smelled like her perfume and something muskier. I kicked off my jeans and panties, spread my thighs, and pressed the fat head against my slit. It was too big. The tip alone stretched me open when I pushed. I spit on it, rubbed the saliva around the head, and tried again. Inch by inch it sank in, forcing my pussy lips wide. The burn turned into a deep, filthy fullness that made me moan out loud.
I fucked myself slow at first, then harder, the wet sounds filling the room. Every thrust made my clit throb. I imagined Mom watching me use her toy, telling me to take it deeper like the dirty girl I was. My hips lifted off the mattress. I came hard, pussy spasming around the thick shaft, juices dripping down my ass onto her comforter.
I didn't stop. I flipped over, stuck the suction cup to the headboard, and backed onto it. The new angle hit something deep inside that made my eyes roll back. I rode it like a slut, slamming my ass back until my thighs shook. Another orgasm ripped through me, stronger than the first. I kept going until my legs gave out and I collapsed forward, the dildo still buried halfway inside me.
When I finally pulled it out, my pussy felt wrecked and empty. I wiped it clean, put it back in the box, and returned it to the shelf. My legs were shaky the whole way to my own room.
Later that night I heard Mom come home. I lay in bed listening to her move around, wondering if she would notice anything different. Part of me hoped she would. Part of me wanted her to walk in and see exactly what her huge dildo had done to her daughter.
