Rack 2 Reinvented (modded game/additions based on Rack 2 by Fek) has a chastity cage added. Besides, the base game has a lot of options for orgasm denial/edging/forced orgasms, and some objectives may even require you to do edging tasks.

The cage is purely optional though, and you have to buy the requirements to craft it.
