Naga of an idea

       As the two of you lay on the ground with Kim the half centaur laying on top of you.  Her human half anyway the ass end of a horse half of her lays to the side while her huge breasts  and upear body lay on you like a lover.

        You watch her horse like ears twich as you breath on them from time to time and rub her breast as she sleeps from the sex you just had with her.  You are about to fall a sleep too when suddenly you hear a voice yell to the two of you. 

        "What going on what is that and how did it get here?" Yells Amy the the girl next door just getting home from some where.  You don't have time to deal with her but suddenly get and idea.  

           Amy stops her yelling and starts striping out of her clothes as fast as she can as her skin takes on a smooth green shine on the back and a yellowish look in the front.  Her legs come together and form a long smooth snake tail.  While all this is happing she is playing with her breats which now are smooth and no longer have nipples . She lets out a fork tongue hiss of bliss as her pussy cums all over the ground.
