"It looks so painful, Alex… and why is it so slick?" Aunt Stacy asked. Her eyes stayed locked on the shiny, precum-coated head of my cock. The thick fluid mixed with water and spread across her lower belly every time I moved.
"I don't know, Aunt," I said, taking my cock in my hand and rubbing the head on her belly as if trying to understand what was happening with my cock.
I gripped the thick shaft and slowly dragged the swollen tip in small circles across the soft skin just above her navel, smearing more precum over her. The heat of her body made my cock twitch hard in my fist.
"Did you get hard looking at my body?" Aunt Stacy asked, as she couldn't believe I could get this hard from the body of an older, mature woman like her.
There was a mix of shock and quiet arousal in her voice. She glanced down at her own thick curves, the massive wet breasts, the soft belly, the wide hips, as if she still couldn't accept that this was what had made her nephew's cock so painfully stiff.
