The hugely popular "Acme Chari" project is back and powered up! This time, it's a competition between two amateur girls!? They'll compete in three types of bicycle races—a tricycle, a wand massager saddle bike, and a piston-style bike—to test their physical stamina and pussy endurance. It's a three-round match: win for prize money, lose for a penalty game. Cumming in front of a friend is embarrassing, but to win, they have no choice but to keep pedaling!
