I Shouldn't Post This but My Slut Won't Stop Choking

She knows exactly what she's doing to you. She's on her knees, her dark hair falling around her face, her big tits swaying with every move. Her mouth is full, but you can see the shape of it, the way it stretches. Her hands are on his thighs, gripping tight.

Her head bobs, slow and hard, taking him deep. You can hear the sound of her throat, the gagging. His hands come in, guiding her, pushing her down. She doesn't fight it, just takes more. You're getting hard, your hand moving without thinking. You're trying to hold back, but it's getting harder.

You're imagining what it would be like to be in his place, to have her mouth on you like that. You're stroking now, your breath catching. She's moaning, the sound vibrating through him. It's getting intense, you can feel it building. How long will you last when you see this?
