Mom was naturally ready for it as it was all her game plan only and in the pretext of pain , she was leading it to sex and fuck. So keeping the show, she said " Oh Son! thank you so much as you are such a sweat to be ready to help me in relieving my pain. But I cant allow you to push it in me. One reason is that your father was just about half your size and he also did sex with me in ass only a couple of times in my married life and he was the only man I had done it ever, So even if you try to help me, I can't take it in me as it is so big and rather it will be more painful that the pain I am getting now.
