So, Saturday morning dawned, and I was downstairs having my first coffee of the day when my mother came down. She looked warily at me as she came into the kitchen, and I smiled to myself: time to see if my domination of her was still in place.
"Come here, mother". She shuffled towards me, a frightened mien on her.
"Show me your tits".
Mother stood for a second, then slowly, very slowly, undid her dressing gown and opened it. No nightdress, just her bare body. The plumptious tits were inviting so I fondled first the left one, and then the right. She looked down at the floor as I did this - and when I tweaked her right nipple she grimaced but remained silent.
"I hope you remember what we're doing today" I asked her. Reluctantly she raised her face up and nodded: "yes, you're taking me shopping".
"Correct, mother. We're going to buy you some new panties and bras - ones for you to wear just for me." At this she shivered slightly.
"Don, I....I'm your mother. It isn't right what you're making me do."
"Why? What have I forced you to do?"
Mother hesitated, and I slapped her left tit in encouragement. "You've..spanked me...you've made love with me.."
I cut her off there: "Mother, I haven't made love with you - I've fucked you. I pulled down your panties and put my rather erect cock in your cunt and fucked you. What did I do?" I gave her tit a sharp tweak and she gasped.
"You..fucked me" she almost whispered. "And how did I do it?" I demanded. Mother gulped and took a deep breath.
"You put your ..cock in my...cunt." Her face was bright red. I turned away - much more of this and I'd be doing it again. My erection was painful!
"Get upstairs, put your clothes on and get ready. I know exactly where we're going."
I expected her to drag out the getting ready bit, but my lesson in obedience had obviously had an effect and she was down in 15 minutes.
