It's another T-girl tease--call me obsessed. They're going to tell you what they really want. Any one could be a genetic girl, but they're not. That doesn't mean they're not "real" girls. They are.
Mandy is a pre-op TS. She really wants to sing for you while you "touch yourself". No surprise that some would call her a shemale. But she's just too beautiful to be ignored. Now, listen to her sing.
Is this another T-girl tease? Probably. But, Morgan has a point to make and you're going to make it for her. Only Morgan and Joy know if you get to cum and they haven't made up their minds yet!
