Leather restraints and a leather harness.

You quickly decide that the Bondage section is the one for you and you browse with bright eyes through the variety of cuffs, shackles, collars and restraints. You'd just love to buy them all, but you have to make a start somewhere, so after a while you settle for a pair of wrist and ankle restraints in red and black. The price looks hefty, but at least it signals quality. This is something decent that will really restrain you tightly and smugly. You feel your pulse quicken and your thoughts race. You want to present yourself to Dave bound and helpless. You add some snap hooks, chains and locks, and, as you are just about to click "Buy", you stumble over a beautiful leather harness, which fits and highlights the female body, exposes breasts and your genital area with a web of straps and o-rings. You add this to your cart, and happily type in your credit card details. The shop informs you that it will deliver the goods within the next hours.

It's good that you have a maid at home who can recieve packages, you think.
