Stepsister flashed big tits and hinted at sex

You can throw pissing rags or even worse, but I think that when I fuck my end, it’s a purely intimate matter and coming into my room at such moments is strongly discouraged, so as not to get hit with a tambourine. But apparently my busty step-sister is not sure about this, so she comes into my room and wanders around it like the Fontanka! Well, since she sees what my hand is doing, she actively helps the process and even jerks off the end with her tits before climbing on it. Well, although overall, of course, it’s debauchery, but damn, how pleasant!
