Abduction fantasy – yep you share this with a lot of other people, a popular subject!

If your girlfriend ever gets around to arranging something like this for your collective enjoyment, please do tell us how it went and what they did. (Just please make sure that y’all carry out the ‘capture’ part somewhere deserted where nobody will observe you. Nothing ruins a good roleplay better than police alerted by concerned witnesses.)

If you would like to put one version of your day dream into prose... well... this is the BDSM Library. A nice nasty kidnap short story is always appreciated.

You just need a beginning, and an end, and... stuff in between.
“Two rubber clad fetish vixens, one in red and one in black” sounds rather hollow. If you would like to write a story out of your fantasy, try to craft each of these masked perpetrators into an individual, with individual predilections, mannerisms, voices etc. The story becomes suspenseful if you give them an interesting reason why they decided to kidnap this particular guy, and this reason is eventually revealed in the course of the plot. (Unless, of course, the story title is ‘How my Girlfriend and her Buddies Finally Fulfilled my Abduction Fantasy.’)

Have fun.
