Key watched as Maria confidently straddled Kevin's face, feeling a mix of embarrassment and arousal. She noticed Maria spreading her feet on either side of Kevin's face, proudly displaying her hairy and wet vagina, with her anus also visible to kevin from that angle. Key couldn't believe she was witnessing this, as she never thought she would expose herself like that out of embarrassment. However, if Kevin had asked her to do the same, she knew she would comply. It seemed like this act was making them more comfortable with each other, much like how comfortable Maria seemed to be with Kevin.
From Key's perspective, watching them made it seem like they were engaged in the most ordinary sexual activity. She observed Maria lowering her hips, pressing her vaginal lips against Kevin's mouth. Once their intimate contact was established, Maria increased the pressure, causing Kevin's mouth to disappear under her vagina, with only his chin visible to Key.
