Marriage therapy

In a last minute attempt
To save his marriage
He tried an alternative
Approach.

He took onboard
A sex therapist
To teach him right from
Wrong

So once a day
He had a session
She taught him how to
Bonk

So when he returned
Home each evening
His cold wife got a
Shock

His technique improved
He made it last
He took her to a
Plateau

Each move was smooth
Each move was fine
As chocolate and strawberry
Gateaux

But alas and alack
My tale is tragic
His competence was too
Perfect

Her suspicions and
Their account statement
Caused her to him
Reject.
