Why would you unlock him? I would humbly suggest you already know the answer to this one. If anything he should be locked up in more ways than just with a device on.
Agreed unless he is bound and can't touch himself then its ok if he is unlocked. Otherwise, Locked and Loaded is the way to go!
I voted unlocked, however he should be bound. My wife uses a spreader bar that leaves me very vulnerable. If it should be a real punishment keep him locked. Have Fun
Guess for me it didn't matter. Mine are usually painful enough an erection is pretty short lived anyway.
The answer depends on whether the spanking is punishment or reward. If it's a reward then he gets what he wants. If it's punishment then he should not enjoy it.
I am with jasmic on this one in that I think you know the answer to this question. He absolutely should be locked up for his spanking maybe even restrained.
I stay locked when get spanked and I think you should do that too. But if my KH really (REALLY!) wants to punish me I get an orgasm before she spanks me. I that case it is no difference if "he" is locked or not.
Bound and legs spread should be a must. Every other time between hits the instrument you are using could softly caress the .....UNLOCKED penis!
I'm always kept locked, whilst I get very close to an orgasm whilst I'm being spanked by my wife the only time I actually came was when she spanked me in front of her Auntie.
I'd say locked. Especially if when he tries to stiffen up it will make him feel the device biting into him hard at the same ime.
Locked of course, My wife spanks me with my legs spread locked to a spreader bar this gives me no protection to my back side. This is how I'm disaplined and it is Not an enjoyable experience
