I touch my stepmom and end up fucking her big ass.

He had grown up without his mother, he didn't miss her, but sometimes he had memories of her breastfeeding him, he didn't feel proud but those memories always left him aroused. One day he was quietly resting in the garden when his stepmother came running in, asking for help.  A viper had bitten one of her breasts and he had to get the venom out of it, he moved closer to her big tits and began to suck, when the taste of venom was over, he could not help but move his mouth to his stepmother's nipple, and when he noticed that she did not remove it, he began to suck it greedily. The pleasure he felt could not have been greater.
