Rika heaved as her head was forced down, her throat closing down around Trina's cock. As she was allowed to come up, the gagging sound was horrible as her head partly pulled away, a slick layer of frothy spit covering Trina's cock, a trail of saliva leading back to Rika's mouth. She barely had enough time to get a breath in before her head was shoved back down, taking the thick member in once more.
