My mom wore the panties I came in 30 mins ago

My mom’s 5’2″ body has been a source of fascination for me, from stolen glances down her shirt to catching her mid-change. With my dad absent and my sister rarely home, my mom has taken to wandering the house half-naked, often wrapped in a towel or playing “cover your eyes” as she dashes to the cupboard for a towel. These encounters have fueled my urges, and recently, I’ve acted on them by taking her panties, starting with a simple sniff, and now finishing inside them when she leaves them lying around.

Today, something extraordinary happened. I was a bit slack with cleanup, and my mom picked up the panties I had just soiled with a thick load, no more than 30 minutes prior. The thought of my cum seeping into her pussy as she wore them is almost too much to bear.
