The Grand Denouement

As he came to me waiting on the couch
Of itself the corded knot fell apart,
The girdle snapped, and down and down
My skirt went gliding inch by inch
Until my hips arrested its shameless course
Thus much I remember, sweet friend, no more.
Once in his arms, our nudities interlocked,
I was lost to the outside world
Who was he? who am I?How went the coital act?
Not a thing I know - nothing, nothing at all.
