Mom has always been a sleepwalker. We've managed it over the years. But last night, she sleptwalk right into my room. I didn't realize it until I felt a warm body press against me under the sheets. I sleep naked in the summer; mom wasn't wearing any more.
"Mmm, hey there sexy hubby," mom whispered in my ear, nuzzling her head in my shoulder and draping her thigh over mine. "I know our boy is back for the summer, but you know how he sleeps. No reason we can't have some fun..." Mom licked around the outside of my ear, running a hand down my chest until it reached my naked cock.
I froze. Mom clearly had mistaken me for dad, and clearly was horny. I thought for moment about how awkward it would be when I told her, but realized it was better than her finding out later.
"Mom," I whispered, turning my face towards hers. She brought her lips to mine and darted her tongue in my mouth.
"Oooh, another role play tonight hubby? You want to be our darling, studly son, fucking me in his father's bed?" Mom asked, breaking the kiss. Her grip on my cock tightened as she mentioned me.
I froze again. Could mom and dad really have been role playing about me? And mom got off on it? Even more conflicting emotions swam through my head as mom lifted her hips over me and straddled my cock.
