The guy was very persistent when he offered his girlfriend a threesome, for which he just brought home a friend who hadn't fucked in a while. The guys kiss the cutie together, but then she realizes that it's better to fuck as a couple, so she sucks the penis of her boyfriend's buddy, who then puts her in. The chick gets more and more pleasure each time, because her body tenses up, ready to explode with orgasm.
