that's power-fucking right there. He fucked his own sperm into her and the residual ran down to where her asshole was being invaded. I only wish they would have removed the plug so we could see her gaping shitter/ fuckhole.
His penis looks VERY firmly erect... it's exciting to see the warm semen start to flow... he is past that point of no return so he just puts it back in and fucks the rest of it into her receptive body. SO good!!
