Mark, with his camera focused on Caroline, witnesses Amon lift and throw her back on the bed.
He sees Amon put Caroline in a very suggestive position with her ass up while on her knees and her head pressed down on the bed, making her back arch up.
He then sees Amon climb up on the bed, approaching Caroline with his massive, thick cock. As he gets closer, Caroline begins shaking her ass, trying to entice Amon with her its thickness.
Mark sees Caroline's desperate movements and feels disgust towards her for acting like a whore, but only because she never gave him any attention.
If it were him in Amon's place, he would have loved every second of it.
Mark watches Amon put his hand on her hips and then shove his cock deep into her pussy. Mark watches Caroline throw her head back, open her mouth wide, and lash out her tongue under the influence of Amon's massive cock.
He sees Amon go absolutely ham on Caroline, breaking her back with every thrust.
