Dad caught my sister and I doing 69 and watched till we finished. His punishment for me was to suck his cock and swallow his cum as my sister was fingered and spanked. He started coming to my room to suck my cock a lot more then watching us 69 until he had me fuck my mom and he popped sister's cherry. Moms was not happy about it but she let me sister and I alone mostly except when dad got nasty and gave us a surprise. After dad passed I became the head of the family and enjoyed my sisters and mom regularly.
