A problem occured while fisting my girl

My wife left for the day
Little did she know I was staying home today
I call my girl she's ready to come by?
She wants to be fisted, oh wow, oh my!
 
My girlfriend is taking it like a pro
I slowly inch my way in, her hole is beginning to grow
I couldn't stop, it's turning me on
Her pussy is soaked, my hand was completely gone
 
I asked if she was ok, she said she felt great
I continued to fist, while I masturbate
Who cares if she's looking like a slut
When I'm elbow deep in her butt
 
Digging for her gold
I think I hit the mother load
Some might think I'm sick
A fist much wider than my dick

She continued to orgasm many more times
My arm had enough, pulling out cum, lube and slime
To my horror something was missing from my hand
While fisting her, I lost my wedding band
 
I told my girl, she began to laugh
Told her to shit it out of her ass!
 
If my wife finds out, she'll cut off my balls
My girl said, I gotta go, if you make it out of this, gimmie a call
