Brother peeked at his sister jerking off and decided he owed it to her to fuck her off

At the brother peeping at his sister was the main entertainment and he finally got to see the way the damsel masturbates. It was so beautiful and sweet that the guy involuntarily had dirty fantasies about kin sex. He began to threaten the chick that he would tell his parents about how she was a onanist. The cutie decided not to allow this and performed a blowjob to her brother, and then let his cock into her cunt and enjoyed a beautiful fuck.
