Spock's Pon farr
It is that time for Mr. Spock again - Pon Farr! If he doesn't release his Vulcan passions well, he did Kirk once! Thank goodness McCoy pulled a fast one! Nurse Chapel has been eagerly awaiting this event for years. She also knows that she is the only female available to Spock! So Mr. Spock receives a proper Vulcan Pon Farr with human Nurse Chapel sucking his cock, using a Vulcan vibrator on her human pussy, then she gets to ride Spock's Pon Farr cock before he fucks her from behind and fills her with his Vulcan load!
