This box set lags a little behind OSK's other box sets. There's some good heavy fetish instruction here, but the cock and ball torture release seems overly long and like it doesn't deserve its own release. Thankfully rope bondage is handled so well that it almost completely makes up for it. The technical aspects are always a little below average and there's no real effort put into the extras. If you're feeling like you need a little help around heavier fetishes, this is a good set to pick up.
