The premise of this story is simple. A son is in love with his beautiful erotic Mother, to such a degree that he must have her sexually whatever happens. So we are allowed to participate in the wonderful seduction of this mother through the sublimation of her fears and the acceptance of her submission to her new lover, her son.
And we learn how willing a lover she becomes as he slowly breaks down her defences and finally impregnates her, a desire she has secretly wished for, ever since her only pregnancy, her loving son.
I am a sucker for a truly good love story, and this one is about a secret desire that many males hold in the deep recesses of their minds, without fulfilling it.
Beautifully told by ppr128 in a way that transcends geographical boundaries, with a subtlety that makes it truly believable.
