Long session with the mistress of your dreams
Now follow my orders exactly (If your chair isn't exactly like mine I allow you to diversify the bondage a bit. The chair which I use is an armchair with an arm- and a backrest.): first untie your toes and put the shoelace aside. Then take the long rope.
Take one of the ends of the rope and tie your left foot to your left chair leg. You may make several knots until it's firm enough. The foot should be external so that your thighs are forced apart more.
Now take the rest of the rope and tie your left thigh to the left armrest.
Now thighten the rope about your belly and your breast up to your shoulders and your collar (of course you shouldn't gag on it). Then pull it to your right armrest. Tie your right thigh to it.
Complete the bondage tying your right foot to the right chair leg. The foot should be external here too.
And now to your hands: untie your dominant hand and connect your non-dominant hand with your balls instead. Tie your dominant hand using the third, remaining shoelace to the arm- or backrest. Tie it firmly so that you cannot move it any longer.
And suddenly you are all tied-up and helpless!
