当我的小继妹在她打电话时，她正在和她的男朋友说话。我在他嘴里

My beautiful stepsister has a new boyfriend, she is falling in love with him a lot, I am jealous of that guy, I don't know what plans he has and suddenly he wants to hurt her or hurt her, I try that when she is with him I always interrupt. This time she talks to him by call and I come to her room to warm her up and she ends up fucking me.
