At first I thought that the grandfather would die at the end of it, but it turned out to be the opposite: he fucked the poor girl and poured a bucket of sperm in her pussy as well. Of course practically all the work the girl did by herself, but grandpa was also on top of it: at that age many of them can't get a hard-on at all. The girl sucks amazingly: swallows the whole cock without a problem, I would fuck her myself!
So much variety in group sex - singles have never dreamed of! All tastes, colors and smells, and even with a stoner!
