Shapechanged into a man, Al slowly inched his cock toward Susen's open mouth.  "NNggh-oh, Ngk-Oh" Susen tried to beg as the cock approached her, then "GGggk, Gggcch" as the cock filled her mouth and began to slide down her throat.  Her head was bent over upside down over the edge of the human-sized butcher block.  Al hadn't gotten half the length of "his" cock down her throat when "he" recognized the signs of an overactive gag reflex.  He pulled his cock out, and twisted her head just enough to let her safely vomit without choking.  He had to repeat it twice more, before she was empty and could only dry heave.  Then he finished sliding it all the way in to the hilt.  Totally plugged, Susen couldn't make any noise, even a choking sound, she could only plead with her eyes.  Al drew his finger along the gauge in the butcher block, where so many had lost their heads.  His finger crossed Susen's throat, and picked up on the other side of the gauge.  His cock was in her throat deeper than the gauge mark.  "If I keep my head south of this dotted line often enough to pour my load down your throat, then I won't cut on the dotted line.  So suck my head and you keep your head.  Capice?"<br/><br/>Al watched Susen give him head.  Her nipples were hard as bullets, and Al could smell the excitement from her pussy.  She was even starting to suck enthusiastically and seemed proud that she was able to take it all the way down without gagging anymore.  Al's hunch seemed to be right.  Either the suit made her submissive, or it detected and attached to submissive personalities.  Either way, Susen was REALLY getting off on this.  Al got into a rhythm of 10 long strokes all the way in, and 5 short strokes to let her breathe.  Susen got even more excited when 'Al started squeezing her tightly bound tits and pinching her puffy nipples.  Al began to use her tits as handles, to add extra force to her thrusts.<br/><br/>((note-this may be extreme, so if this doesn't sound like what your character would do, let me know and I'll edit it))
