Four current female university students are invited to a mysterious room where penises pop out of the walls!! Aiming for the prize, they try various methods to make them ejaculate, but panic as the 30-minute time limit approaches!! Throwing away their shyness, they perform double handjobs, acrobatic vacuum blowjobs, leg jobs with visible panties, and other amazing techniques that lead to non-stop ejaculations!! While surprised by sudden eruptions, they lick and make the clitoris wet!! The punishment game is even more brutal, involving remaining penises and creampie sex!!
