When I was 16 my mother found out my Dad had another woman for about 12 years and a son with her. My parents got divorced, my brother stayed with our mother and I went to live with my father, his mistress and my half-brother. My half-brother and I are very close and when I was 23 I told him I would like to take his virginity, and I did. Since then we have sex occasionally. MY other and full brother found out about it asked me if I would to try a threesome. I got really wet just thinking about it, and it happen. And it happens until today and we do it on camera.
