A Fantasy I want to come true.

this is just one fantasy out of many that I have, I would like to meet someone, who would be prepared to tie me up really tight, so tight that I would not be able to move a muscle, I would want him/her to use and abuse me in every way conceivable, orally or anally, or even both, I would be prepared to swallow if he decided to fuck my mouth, and to take bareback if he decided to cum inside me, I have always wanted to be seeded. But the crunch comes, when without my knowledge, a third person has been invited to attend, and arrives after I have been fully used the first time, and then forcibly fucks my mouth, and the precedes to fuck my arse for a second time, and also dump his load inside me. I want the total feeling of being absolutely helpless to be able to anything about it, I would really struggle, just to see if I could prevent being F***d, but to be completely satisfied, I would want to feel him cum inside me as I continue to protest and squirm.

An added bonus would be for photos or videos of me tied and with cum dripping out of either end.

I have to be completely oblivious to any arrangement not known to me, for this to work the way I Invisage, if it did, I think I would have an involuntary ejaculation/orgasm.
