Nagi, the loser of the previous bicycle endurance game, finds herself stuck in a free-use-wall. She’s been injected with strong aphrodisiacs while the winner of the bicycle game has been granted permission to do whatever she wants with her. Though, Nagi does have a chance of redeeming herself from losing the last session. All she has to do is hold her climax until her opponent is done with her. However, given the amount of aphrodisiac that have been administered to her, the chances of completing this task are close to zero. Her trainers still expect her to try her best, as she’s going to be placed on an indefinite orgasm ban, should she fail again. Days, weeks or even months of constant edging without relief await her if that happens~
