It's painful enough to bring tears to her eyes... but the feeling of domination makes her excited, and she dribbles out vomit as she cums over and over again during deep throating. "I can't breathe... but please thrust deeper." Her head is grabbed and her mouth is thrusted hard, and her clitoris is stimulated deep inside her throat, making her climax repeatedly with sobs. The large amount of sticky vomit is proof of Kokoro to her master! She's embarrassed and doesn't tell her master, but she loves forceful deep throating.
