Ground against a pillow face-down until I came shaking

I was alone in my room and locked the door out of habit. I got on my stomach under the covers, grabbed a pillow, and pushed it between my legs. At first I just ground against it slowly, feeling the soft pressure against my clit through my panties.

Once it started feeling really good I pulled my underwear to the side so I could rub directly against the fabric. I went harder, rocking my hips and pressing down with more weight. My free hand gripped the sheets while I kept the same rhythm. The friction built fast and I didn’t stop.

I came with my face pressed hard into the mattress, thighs shaking and hips still moving through it. The orgasm left me panting and I stayed face-down for a long time afterward, still grinding weakly against the pillow until the aftershocks finally faded and I could roll onto my side.
