"I've made a proper condom, so it's okay to have sex," he says, but reports that the condom was torn and he ended up having sex with his younger sister raw! My sister took it in a health and physical education class

My sister gave me a condom in her hand that I had in her health and physical education class, and she couldn't refuse and just let her go. Just as I thought I had successfully completed the installation, my sister suddenly changed! ? He straddled me and said, "I had proper birth control and it's okay to have sex." However, it broke halfway through and was in a raw state! What's more, my sister felt even more so I let her go. My sister and I got even raw...this is force majeure, isn't it? My little sister wanted to have sex!
