I have been searching for a mate for so long!  Unfortunately for me, it has become extremely difficult for me to find a compatable mate among human males and my breeding cycle is nearly at an end.  That is why when I picked up your scent, I knew I had to follow you and beg you to fuck me.  You may be my last chance to help me continue my line.  Won't you help me?  Please?  

I promise that it will be very pleasurable for you.  I'll begin by sucking your cock and indulging in the taste of you as your cock swells and your ball become heavy with cum.  Next I'll mount you and ride your cock, begging for you to realize a gigantic load inside of my pussy.  In order for your seed to take root, we will have to cum simultaneously - but I can tell by looking at your cock, I will have no problem reaching orgasm at the moment you cum deep inside of me.
