Why would a lover leave?

Just a thought I had this morning.

---

The emotion of close, touching flesh,
heat exchanged through moist breath
Why would a lover leave?
From your arms they reluctantly heave
Despite attentions where you tease and smear
duty calls.

Far outside these comfortable walls
Waitrose creed is soon spent
M&S food halls have catered
How can penetration compete?

Alone now, the passions of copulation retreat
and you lay curled in the half-filled bed
running the events back excitedly in your head
and reluctantly you react again,
will your true desire be fully fed?

Despite what you think,
reality joins you at the sink knowing,
They’ll be back.
