I've been in a mff and mmf. they were both great (:
I have two.
one night we went out with some friends and Master gave me a sall wireless vibrator to wear. he turned it up and down the whole night. and everyone could tell.
second was when Master invited a few of his friends over and Master let them all do me.
both were humiliating. but i still loved them
Once I forgot to say "Sir" and my Master tied me up naked and blindfolded and just left me there for several hours. torture.
