GF experiences intense pain during amateur penis massage

My main girlfriend Flaquita was at our house and decided to help me with a massage. It's worth noting that she had never done this before, but she was eager to try. The girl started massaging my cock, but she was too rough, and it began to hurt. I asked her to be gentler, but she continued her harsh actions, causing intense pain. Despite the discomfort, I tried to enjoy the experience, but it was difficult. Suddenly, her friend came to our place and saw what was happening. He was shocked and told her to stop. The pain was unbearable, and I was relieved when she finally stopped. The experience was not what we had expected, but we learned from it.
