I Modeled For Extra Money During College

I showed up for a session, had never posed for this guy before and he seemed really nice, few hours later I left when he was done and made pretty good money. He asked if I would do some more for him next time, something a bit more edgy involving bondage but certainly no pain or anything like that, just tied up shots. I thought why not and he offered me another five dollars an hour for it. When I returned and he began getting me tied up after about twenty minutes I found myself in more than just a few ropes and could not really move much at all. He had put this ball gag in my mouth so not like I could talk then came these leather looking eye covers strapped on my head. I was feeling a little nervous but things were going okay so far as I listened to the camera clicking away then few minutes later felt fingers running over my breasts and playing with my nipples and he said "Just getting them erect" and I tried letting out an Uh Huh of sorts but not sure what he heard really. Minutes later more touching then sucking on them and I knew things were not looking good for me being completely restrained and not much I could do about it, the one thing that was keeping me from really protesting was if felt great.
Well he took my little moans and sounds to mean all was good for sex and quickly moved to licking and playing with me further down and again, it was feeling really good and it had been quite some time since my last boyfriend. He kept it up and my orgasm came on strong, he did not stop there though and kept it up for several of them until I was really protesting because my clit felt like it was just getting tickled now which was sort of uncomfortable. He finally stops and tells me this was just amazing and the video is going to be just great, my mind registers what he said and I am like Video?!?! thought this was just photos.
He gets me all untied and I am standing there so conflicted because I really did enjoy it a lot, m body was still tingling and feeling the effects of all the orgasms I had so I asked him what he meant by video because I really did not know about it. He just said, read the contract Honey and gave me the money he promised, I had no idea what I did with the copy he gave me from the first session.
I never went back to him again but part of me really wanted to because he brought things out in me that I had never experienced in my life.
