Would you let me fuck your mum? I am a fine upstanding young gentleman, and I'm sure your mum would be pleased to have such a loving and tender stiff penis inside her vagina. I'm not saying your dad doesn't please her properly, I'm just saying he doesn't really know how too, and that a young buck such as myself could easily out do him in the bedroom with such a fine mature woman.
Of course, after I have finished fucking her I will leave, and never contact her again. I'm sure she won't mind however, seeing as one night of such pleasure could keep her happy for many years to come.
So how about it, would you let me bed your mum, and make her the happiest woman alive? The choice is yours.
Mom's the word.
