I've been playing Rise of the Tomb Raider on Survivor, the hardest difficulty, and every time I die, I add 10 hours to my chastity time. You could probably do this with a number of other games as well for anyone into Chastity/Denial ;-)

Or I suppose you could edge every time you die, until the end ...

Some of the most arousing femdom shoots (for me) have been from Divine Bitches on Kink.com, Teasing-Video.com has quite a selection of tease and denial shoots as well. Quite a few shoots from these sights can be found on various tube sites as well, should you be *ahem* short on money
