   A Pact is made Chapter Five

   When her grip relaxed on his penis, the cool air chilled some of the
perspiration on his body but not the need of his own desires.  Cock in hand
he looked to the other bed partner now curled in a fetal position away from
where they were.

   Cuddling behind Mark, his cock nestled to the ass crack of the bowed
body.  He reached around and grasped Mark's now soft and flaccid tool as a
lever to press himself harder into the bent body.  He spread one cheek of
the snuggling ass and nudged his cock closer to the winking eye.  Wet from
the girl cum on his hands, he applied some of the slippery fluid on both
himself and the wrinkled bung.  He eased the purple head gently forward
until penetration began.  The tighter grip surrounded his tool with warmth
and feeling.  He grasped at the flaccid cock again to find it now filling
to hardness and form.  He pulled more with both his grip and pushing of his
own hips until a decided pop engulfed the struggling head.  He had invaded
this one now.  By now Mark was fully aroused and willingly began his own
participation in the performance.

   Now Ben could feel the decided pulsing of the fuck chute around his
cock. Further, he entered until he was deep as their bodies permitted. 
Slowly he withdrew, easing his raging cock to ripple past the tight
sphincter muscle gripping him before slamming deep again into the bowels of
his new partner.  A rhythm began between cock invader and ass cunt that
stroked both user and used.

   Ben lashed the now raging cock in his hand making sure he applied a
tight ring around the glans preventing any escape.  Harder he stroked and
deeper he plunged as both men became preoccupied in their own passion.  His
other hand clasping Mark's shoulder and neck became a target for the
unoccupied hands of Mark.  Ben offered no resistance as Mark inhaled the
fingers and matched the stroke on his cock with pushes and sucks on the
fingers.  Each shove inward abraded the prostate of this man toy and pulsed
as Mark reached climax was punctuated with spurts of ball emptying sperm.
It had soon covered the masturbating grip.  Not missing a beat, he swapped
hands to lick at his own spunk.  Ben was beyond stopping as he also pumped
his long reserved load into a deeper part of Mark's rectum.
