The delivery

 When my Wife Jessica met her new Master it became pretty clear to me that my opportunities for making love to her were going to become as rare as hens teeth. It was a surprise therefore when Onjye told me that he needed me to keep his Woman happy when he is away on business.

"I'm having something sent to you in the post cuckold," he said, "and you had better make sure that you use it."

'What could it be?' i thought. 'It can't be a cage for my little willy because Master has already had Jessica fit one on me, so maybe it's the key to the padlock so i can make love to her when he's away? Perhaps it's viagra?'

i was very excited at the thought of having a proper married relationship with my Wife again, and i couldn't contain myself with excitement. Jessica said nothing however and told me not to get too excited.

The parcel arrived the following day and, after opening it up, i couldn't work out what the strange item with the straps and small pole was for. But Jessica understood immediately its humiliating purpose , and within minutes she was giving me ...

... the perfect demonstration.
