Miki Hoshino, a beautiful pheromone-filled beauty, takes on the “Cowgirl Time Trial!” If you can make a man cum in cowgirl position within 5 minutes, Miki Hoshino wins and gets a prize! If you can't do it, it's a punishment game! As soon as the cock is inserted in the cowgirl position, Miki's vertical cowgirl position is dangerous! If you do something like this, normally it will be too erotic and you won't last more than 5 minutes! The best part is the piston while worshiping Miki's naughty round butt in the pile driving backward cowgirl position! A must-see is the way her big butt dances and moves lewdly! Well then, it will be fun to see how the outcome turns out...!
