Mario took me firmly in front of our wives, making me feel like I'd never felt before. The pain his thick cock caused me with every thrust was intense, but while part of me wanted it all to end, another part of me didn't want to give up that feeling of being possessed. He addressed me in a feminine way, and I realized that in that moment I truly felt like a woman! Fabiola and Wanda looked at me, smiling sweetly as I moaned and panted with pain and pleasure. Mario lasted a very long time, and I began to feel a strong heat starting from my anus and radiating until it reached my brain, which was incapable of reacting in any way to the situation. When I felt him come inside me, panting, I felt a strong sense of satisfaction for having been "good" at making him come. As his sperm dripped from my dilated anus, I felt truly female and felt a sense of emptiness from the lack of that cock inside me. That day Mario decided to call me Roberta like an ex of his who he said had the same ass as mine.
