My mother-in-law, can make me cum faster than anyone, (experience matters), but by the same token, when I displease her, she has no qualms of dropping her towel & putting me over her knee, until I promised to be a good boy & do whatever she wants.
My mum seduced me when I was a teen...she was very kind when I exploded too quickly, and enjoyed helping me last longer. I exploded in seconds when we first fucked, but she was very understanding, and taught me most of what I know about sex.
