義理の姉が家の周りの雑用をして、結局それを吸い取ってしまいます

My stepsister is clear about what her duties are in our house, she knows that among the many jobs that there are to do in the house are those of pleasing me and satisfying my desires, so on this occasion after doing all the housework she always finishes with the most pleasurable task and that she knows how to do best, which is sucking my cock until my milk reaches her mouth. And this time was no exception: my milk reached her little mouth.
