Girlfriend's forbidden rendezvous with her boyfriend observed by her friend

As I was sneaking around with my girlfriend, her friend suddenly appeared. She caught us in the act and decided to join in on the fun. I couldn't resist the temptation and invited her to stay. We all sat down together, discussing the taboo of a threesome. Little did we know, my girlfriend had been harboring feelings for her friend all along. The atmosphere was electric as we got down to business. My girlfriend wasted no time, diving right in and taking her friend's breasts in her mouth. The sight of her friend pleasuring me only fueled her desire. Before long, she was naked and ready to join the action. We indulged in a wild session of sex, with my girlfriend eagerly taking turns with her friend. The experience was intense, leaving us all breathless and satisfied. The forbidden became reality, and we all left with a taste of the taboo.
