I have a long-term fantasy of being used as a party favor either myself or as one of several m/f's used for entertainment and pleasure.  Is this something that could ever occur?

So  checked out the Urban Dictionary.

I presume you are referring to the roles whereby you provide sexual services of some nature as in definition #9?

That is definitely not what I meant.

Because when you said you wanted to be a party favor for a bunch of people, I assumed that you wanted exactly what mrfischer directed you to.

Basically a variation of number 9 (I was reacting to some on the earlier ones).  Essentially would love to be used myself or with a small group by a dom and friends for their, entertainment, amusement and however else they wished to use me/us.

I think the ideal situation would be to be the party favor at a SunStone Cosplay Party

And yes, they are very hot, especially the way the one on the left is peering over her glasses!  I'd be her party favor anytime

but if you're looking for a p2p experience, it's going to be QUITE expensive.  

my domme used me as a party favor, she had about 4 of her close girlfriends, i had to serve them refreshnents, and do whatever they told me, it lasted for hours, and all had an enjoyable time.

This is the kind of post that you shouldn't skimp the details on!  Sounds like a fantastic night!
