Time to do some tests:
Does the dick cup teleport? Lock the cup in a closet and throw away the key
If it does not teleport and indeed shatters the door as it flies through, you'll need to test overall strength. I'd recommend placing the dick cup in a 10 gallon bin of wet concrete, waiting for it to dry, and then taking a nap
Fall asleep with your dick in your wife's pussy. What happens? (Might be dangerous, don't want the cup to hurt her)
