Treated my stepbrother to fragrant pussy

The girl noticed that her brother had pulled off her panties again, and came to give him a pussy (of course, in a figurative sense). The dude was silent, like a partisan, and didn’t want to admit it, but then he said, as if in spirit: yes, I jerk off to my stepsister, the constitution doesn’t seem to prohibit it. In general, the sister decided to put an end to this disgrace and had sex with him. Maybe now he'll stop fucking her underwear. Well, where does this fit: the girl can’t go to whores, because all the panties and tops are from different sets!
