Yes, that's the one.
The earliest point likely occurs around the 15:00 minute mark (the tan bed runner is present and he's not all covered with sweat), and runs through to the 29:50 minute mark ending. Not straight through, because of the jump cut around the 21:20 minute mark, where she addresses the camera/Matthew directly (after the bed runner has been removed).
The last portion starts at the 0:00 minute mark, and while we see the bull tease Jen by playing with the base of the butt plug during the double penetration, we never see either of them remove it (she actually has to hold it in with her hand).
My guess: he probably did penetrate her ass after stretching her out with the toy, but that portion of the footage was excised during the reordering.
