The dude brought the friend's chick to orgasm
When the guy realized that it would not be possible to bring a young brunette to a violent orgasm on his own, he brought a sidekick to visit and put an insatiable beauty under him. To begin with, a modest bitch dutifully sucked off an unfamiliar dude, and then turned into a real slut and let her shaved slit be fucked right in front of the cuckold.
