Author's Note: Requested by Shironomi. Holly wasn't like most centaurs. Most in her age group stood head and shoulders above her, almost torsos above human girls, with some that nearly doubled others. Her mother was one such centaur, several feet of legs that supported a voluptuous torso with tits half the size of Holly's whole body. All that said, she didn...

Dear Kate, I can't believe the things you said in your last e-mail! How could you, after all we've been through together? You really hurt me!

Just a little larger "Maybe 23 cm," I said, "just long enough to fill me completely full and grind on my clit. And a little bit bigger around, 15 cm?"

You're very big for a...

Fetish

Ch. 2 The Bar We went to the nearest quite bar that I could think of in a hurry, attracting every single view along the way, which was not quite surprising. Obviously, Megan was an eye-stopper being as tall as she was.
