I have my slave gimpy bound in a barbers chair, head hooded, arms in a straitjacket, and legs strapped together. Helpless, as usual. I vigorously tease him with my hand, bringing him to full mast. A slave is always weakest when he's aroused and hard. So naturally, it's the perfect time to catch him in a deception: I know he's been secretly jerking off without my permission, and I will get the truth out of him while my hand controls his orgasm.
