Cuckolding: with Jack and Jill

In a house, not plain nor tame,
Lived a couple, sans any shame.
Jack and Jill, they were their names,
Their love life? Not quite the same.

Jack said to Jill with a grin,
"Let's invite someone else in."
Jill nodded, with a sly look,
As if she read from a different book.

In came Joe, with a strut so bold,
Into a story that's rarely told.
Jack sat back, with a view so keen,
As Jill and Joe set a scene unseen.

Jack, the watcher, with a smile so wide,
Jill and Joe, no need to hide.
A game of love, with rules unbound,
In their little house, where joy was found.

Oh, cuckolding, a tale so old,
Some girls want more than diamonds and gold.
A story of love, trust, and play,
Where everyone's happy, in their own way.
