Frustrating Orgasm

Mistress Amber has her bitch right where she wants him, with his balls tied tight and his face buried between her thighs. His balls are in uncomfortable pain from the rope but Amber keeps stroking him, keeping him hard. If he wants to cum he will have to push through the pain. She strokes his cock, making him become more and more horny and hard. She gets off seeing her toy in such sexual frustration, controlling both the pleasure and pain that is inflicted on his cock. Her pussy gets wet just watching him struggle to get off.
