This is a very engrossing story. I love how you've managed to give them a gentle progression while underlaying the main story with dramatic elements and the tense anticipation of Jensen's potentially dark revelations. It really works.
And the boys are both intensely endearing. I can just imagine how poor Jensen had to go jerk off after massaging Jared, drooling inside and all the while acting totally professional on the surface. His patience and obvious emotional depth make it easy to see why Jared's so smitten. And this Jared is so sweet and brave and playful; I adore this version of him. No wonder Jensen is willing to try so hard.
I especially liked the way you make Jared sexually repelled/attracted by anal play; it really grounds the sex and makes it more believable. The whole smell thing is exactly what a guy would do, and that makes it better.
