Naked Desire

erection lasting full pose
Facing towards the classroom ensured that everyone studied my anatomy.  The first time I got and erection during a pose my first thought was to end the pose,  but, as the seconds ticked the drawing class went silent.  A thumping in my groin traveled through my torso.  It was not just my genitals being exposed that excited me so, it was the display of a lust for it that sent me through the roof.  I closed my eyes and took a deep breath realizing 20mins were still left before break.  I was trying to settle down and relax and allow my erection to subside.  Ironically, these efforts had the opposite effect.
