I loved that scene albeit bittersweet. Brian is aching but looks so beautiful although he's in so much pain. He takes his time to savor the moments with this Justin look alike so he can take it all in. Ahhhhh I hurt too watching him in agony.
When he finally mounts him, he spares him not and just thrusts, raw. Boyfriend moans & cries out a little, in painful pleasure. Seeming to brace himself for what's to come. Wow! Deep scene.
