I am sure you love her, she took care of you all those tiresome years, she cooked for you and even worked hard on keeping you well fed and most of all she loved you. Remember the time you got your penis stuck in your zippers, she was there to get it out using her soft hands. You could tell she felt honored by this and do you still remember the first time you took a shit, your mum was there watching you relax your asshole. She even fingered you to make things better.
And how could you forget the time when you had your first sex, she was still there watching from her hidden closet while your prick went limp, when the time came and she didn't say a word, instead she made you dinner and padded you on the back. You felt great and it's all because she cared.
She didn't even mind when you sucked soma out of her. You used to bite her nipples and suck every last drop out of her perky tits but she didn't mind, even though she feared she will lose her wonderful tits shape, she still didn't care because at that point she loved you and she cared about you.
Think of all the bad things you have done, rape, murder, incest and so on and just imagine how hurt she felt when she heard about them, imagine her pain as she walked past your dad and went out for some air. But she kept it together and still loved you.
This is what mothers do, they love, adore and cherish. You're connected to her, it's a bond more pure than any other, she feels your pain, she cares about you and most of all, she understands you. Although I had perverted intentions while writing this thread but even I can't joke around when it comes to mothers. Love them and respect them.
