He thought he was in control

My SO and I have been playing around in the BDSM world for a little bit and it's taking me some time to bring or rather train a dominant side into myself. He is amazing when it comes to dominating. He knows exactly when it's becoming to much for me or when I'm starting to feel uncomfortable in any sense of the word and he stops to ask me and make sure I'm ok..... anyway moving on. He has really wanted me to be a little bit more dominant every now and then. He never pushes it on me though and he's letting me develope that dominant side at my own pace..... well tonight I completely surprised the man.... to many of you it may not seem like much but it was a huge step for me.... He came into our room and we started playing around and per usual he went straight to the dominant roll throwing me on the bed and stripping me and telling me how much he was going to drive me insane tonight. Little did he know what was in store for him. I was under him as he kissed and bit my neck and I took his shirt off and undid his pants. But during my undoing I slid his belt off and whipped him (obviously not to inflict pain). He had thought that he was in control but really I was. He was instantly as hard as a brick moaning.... I used the belt around his back to pull him as far into me as I wanted. He was so turned on. I then used the belt as leverage to turn him onto his back and I gave him a blow job using the belt to put a little bit of pressure on his neck while I did it. I have never made that man cum as fast he did tonight. Couldn't be more proud of myself!!!!
