Up all night

Contest entry with the prompt, Up All Night.

Fifty years of marriage
have taught me a thing or two.
You fill me full of passion,
I still want sex with you.

But watching you undress
now takes a little while.
The enormity of your knickers,
your wobbly vertical smile.

You give a little wiggle,
tease me with your ass.
Pull on a flannelette nightie,
drop your teeth into a glass.

I suggest a little gumming,
undo my trouser zip.
You turn your back toward me
exposing your false hip.

I take this as a come-on,
but my advances you do shun.
After I've taken my Viagra
curing Penile Dysfunction.

I try and change your answer
because I have sexual needs.
So I play with your bikini-line
just above your knees.

Your hair is thick and soft,
as beautiful as a mane.
Then I suddenly realise
i've got your varicose-vein!

But this seems to do the trick,
the same thing is on your mind.
rolling over to face me,
you leave your tits behind.

Several hours late
you're sleeping safe and sound.
I just keep on going,
in and out I pound.

Finally I've finished,
outside the day is bright.
I might be no spring chicken,
but I've been up all night!
