 Chapter 2 (This chapter is kind of a tease again.  Back on topic next
chapter)

   The drive to my sister-in-laws was uneventful, and it was obvious the
thoughts of both myself and my wife beside me were elsewhere.  I look in
the rear view mirror at my son in the back seat, thinking back to our
shower this morning, and how I had gotten hard when my son spanked my
bottom.  Then I thought about fingering his bum and rubbing nipples when
washing him.  After, my mind turned to walking in on my wife massaging his
little asshole.  I was certain my wife was going to want to leave as soon
as we possibly could without seeming rude.  Unfortunately the drive was
almost an hour each way, and the torment of thinking over this morning made
it drag on for what seemed to be an eternity.

   Thankfully the event passed without incident, and several hours later we
were headed back home.  About halfway through the drive, my wife was
noticeable squirming in the seat next to me.  I noticed she had drank a few
coolers throughout the afternoon.

   "Honey, can we find somewhere to stop I need to pee" she said after a
few minutes.  I glanced at that clock on the dashboard, we still had about
20 minutes until we were home.  I knew I could have some fun with this.

   "I don't know how many places we can stop between here and home.  Can't
you wait It isn't much longer." I already knew that she wouldn't be able
to, at least not without making a bit of a mess on the seat.  It would be
worth it though.  My wife gets super horny when she has to be, and I know
that wetting herself is something that turns her on.

   "I doubt it.  I think I had a few to many drinks before we left" she
said with a giggle.  She was still squirming in her seat.  I reached my
hand over and put my hand into her pants.  As assumed, she was wet, and it
was likely a combination of her juices and pee.

   "Honey quit it.  Our son will see you" she said.  I looked back at our
six year old son in the back seat.  He was smiling at us.

   "Like it's any worse than what happened this morning." I said with a
smile.  "You didn't seem too concerned when you were rubbing his asshole
this morning."

   "Probably no worse than your shower time with him.  I hear you splashed
him" She shot back.  My only response was to push on her clit, sending a
jolt through her body.  I felt a small spurt of pee come out before she
gets it back under control.

   "Honey, we have 10 minutes until we are home, you'll have to wait to
pee" I said, pulling my hand from her pants.

   "Haha, mommy has to pee-pee!" the small voice chirped from the back.  I
smiled at my son in the mirror, and kept driving towards home.

   As we pulled into the driveway, my wife jumped out of the car before I
had it in park.  I noticed a larger than expected wet spot on the seat, as
well as her pants.  I could here the sound of liquid hitting the pavement.
As I leaned over, I could see my wife wasn't making it inside, as she
released her bladder all over the driveway beside our car.
