Begin with his right hand. Attach one end of the restraint around his wrist (not too tightly) and the other end to the corner of the bedframe. Try to make sure that his arm is fully extended but not stretched uncomfortably. This tease is going to last for a while, and you want him to be thinking about what you’re doing to his cock, not how much his arms and legs hurt. When you have his right arm secured, tell him that you’re so excited that he’s letting you put him in restraints. You’re really looking forward to being able to do whatever you want to him once he’s all tied up and unable to get away from your mischievous fingers.
