Cosplay Cafe(2004)

Tomoya Asahina has been left in charge of a failing cafe. To revitalize his business, he has his team of busty waitresses switch out their usual uniforms for cosplay costumes! Tomoya also has a crush on one of these waitresses, the demure Akiho. But Tomoya doesn't have much experience with sex, so all the other waitresses get together to give Tomoya some lessons in the art of love!
