Dirty outside fun

(This was written for a friend - her response will be posted tomorrow)

I think I just found the perfect place for some dirty outside fun. The
showers at the campground I'm at take 75 cents for three minutes.

You, me and $1.50 could do some serious damage to the reputation of the
camp as a "family friendly" park.

We strip down in a small cubicle outside the shower, and as your hands
start to make me hard, I toss in three quarters and the hot water
turns on.

I'm feeling generous so I push you up against the poorly painted
cinder-block wall and spread your legs apart with my knees. I don't
need lube or a formal invitation so I split you open with one thrust
and order to you start fingering your self as the hot water sprays
across you exposed skin.

You prop yourself against the wall and lift one leg, giving my cock and
your fingers better access. We can hear the timer ticking and know
that your three minutes are almost up. The block wall scratches your
ass with each of my thrusts. We hear a line start to form outside, but
our three minutes aren't up. The one minute chime goes off and I
increase the depth and speed of my thrusts. 60 seconds, 120 thrusts, a
count down to climax. With 30 seconds left your knees give out and I
impale you and hold you against the wall, tongue-fucking your mouth as
your orgasm rocks you. Your breathless gasps turn to shrieks as our
time runs out. I reach upward and pull down three more quarters from the
stack on the top of the wall

"My Turn!"
