Rain, drain, pain

I looked out of my window and the sky was all plain.  
I moved out of my house and walked in the busy lane.  
While crossing unknown faces i saw my ex-gf Jane.  
I stopped her nervously and my behavior was probably insane.  
She laughed," You are still shy. You haven't changed at all, Shane."  
Her smile was followed by thunder in sky and sudden rain.  
We ran for the cover but all our efforts went in vain.  
Every drop on her face was glowing like wheat's golden grain.  
She was looking like a fairy in white dress dipped in champagne.  
The wet and empty street gave me chance to start the compaign.  
I grabbed her wrist, pushed her to the wall but she didn't complain.  
She reciprocated my aggression by grabbing my mane  
And whispered in my ear," Help me. I want to drain."  
I slipped my fingers in her dress to give her pleasant pain.  
The sudden shock and suprising pleasure confused her naughty brain.  
I apologised to her but she replied,"keep doing it.no pain,no gain."
