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.
This was one of OSK's weaker instructional releases. There's a good amount of information covered here, but none of it really seems new. Instead it all seems slightly tweaked from other bondage releases to warn of the dangers of damaging the cock while feeling like it would have been much better as a fifteen or twenty minute segment on a bigger instructional bondage release. The technical aspects hover around the average level, but there's no real effort put into the extras to help it out. This is a slightly below average release.
