Fi was in as good a position as any to feel Sherrie's orgasm claim her, unrelenting in her teasing of Sherrie's chest.  She watched in rapture as Sherrie's body danced in her lap, convulsing with stimulus in her most secret of secrets, the arm around her front holding her ever so slightly tighter as her slick skin glided across Fi's own.  But as Sherrie continued to come and come and come seemingly without end, Fi couldn't help but feel apprehensive; how long was this supposed to last?  Why hasn't she come down yet?  Could I cope with one lasting that long?<br/><br/>Even as her nerves finally subsided, and the ringing in Fi's ears dulled down after Sherrie's howl of climax, Sherrie was still twitching and shivering, each one wrenching a sob from the girl in her lap.  When Sherrie spoke again, it was a hushed voice, one of total elated exhaustion.  What Fi had just seen was incredible; the thought of her last orgasm lasting as long and as intense as what she just saw instilled a sense of warm, inviting terror.  She wanted it so badly, core already tingling at the thought, but with the trepidation she'd expect of someone awaiting their first skydive; deathly afraid of taking the plunge.<br/><br/>Fi gulped loudly, still astonished.  "Amazing," she said from underneath her lover, watching her flushed face drag in air.
