A benefit or drawback depending on how you looked at it of his hard skin was Pakod's lack of sensitivity,  in some cases like being able to shrug off a phaser set to kill or a marathon sex session, benefits, rolling over the pad containing your senior year academy thesis the night before its due because you didn't feel it, downside.  so smirking as he feels the ensign's cunt clamp down on his rock hard member he pulls back and REALLY lets her have it, he fucks her harder and deeper than he has so far.  He chuckles to himself, "I wonder how long I can keep her cumming."
