Looking for a story about a man being brought into a triad with his sis and fiancee

[jonnielove]

I was reading a fascinating story of a man who got caught spying on his sister and bf. Then got blackmailed by the bf into giving him head daily, then blackmailed by sis into servicing her. Then forced to be a cd at her bachelorette party sucking off the dancer before the story was to be continued right before he was to attend his sisters fiancees bachelor party. Does anyone know where it is and its title?
