Around midnight, Mom came home three sheets to the wind from her girls' night out, catching me watching porn on the big screen. I wore only shorts and my boner made a very obvious tent.
Giggling, Mom flopped onto the sofa next to me. "Gunnar's grown up, I see."
I turned and caught her looking at my tent, but with amusement, not shock. Maybe even lust.
"And my mommy's the sexiest woman on the block," I replied with a grin. She looked up and caught me looking at her nipples protruding through her thin top.
She giggled. "You think so?" She jutted out her chest and wiggled it.
"No question," I replied, putting a hand on her thigh, right below the hem of her short skirt. Before she could react, I leaned over and sucked the nearest nipple into my mouth through the thin fabric. Somewhere in the night her bra had disappeared. Did she even wear one when she left? I never noticed.
"Gunnar!" she exclaimed with a slur, "What are you doing?" However, rather than push me away, her hand pulled my head into her breast. Action and words, that thing.
Emboldened, I let my hand slide up her thigh, making circling motions.
Her head tilted back with a big sigh, and her legs opened wider. "Ahh, my lovely hunk of a man. You make your happy mommy feel sooo good."
