Bound BF Ruined Watching Hogtied Girl Struggle

The scene starts with Nicolas naked and tied to a chair, hands bound behind his back, duct tape gagged and completely at Diana's mercy. She's already caught him masturbating to a hot bondage clip and now she's turning the tables. Diana unties his hands briefly, hands him the phone with the same video looping: a gorgeous girl hogtied, ropes tight, gagged, squirming desperately with those delicious muffled moans. 'Stroke to her,' Diana purrs in Spanish, stepping behind and pressing her hand firmly over his tape gagged mouth, muffling him further as she whispers teasing, dominant remarks in his ear. Nicolas pumps eagerly to the struggling, moaning girl on screen, his sounds stifled under Diana's palm. She patiently waits until he's right on the edge of cumming, then pulls his hand away. Laughing hard, she watches his ruined orgasm burst hands-free - cum shooting out wildly, no touch, no satisfaction. Giggling, Diana quickly re-ties his hands and leaves.
