If you count one dick and one strapon, there have been a lot. Slave, Sonya, Alpha, LadyV, ParisPlz, Purrrsia, Sweet Ally Green Eyes... to name just a few.
I find it interesting that the topic is obviously directed to the ladies and only one lady has chimed in. That should tell you something OP.

I have with toys! Dildo in my vagina while he fucked my ass. Felt pretty fucking good. I was rather surprised. I've also done it to myself while masturbating. Vibrator in my butt, dildo in my hoo ha, and wand on my clit. Best orgasm. Never with two guys before though.
