i walked in on something today that just shocked me. i got off work early and came home the kids had a half day of school so i expected them to be home i walked thru the door and no kids so i went from room to room looking for them i got to my step daughters room and noticed the door was cracked i looked in and what i saw was my 15 yr old step daughter naked being fucked by her 13 yr old boy friend and my 13 yr old son. i didnt know what to do i stood there in shock they was fucking her good my son was fucking her pussy while her boy friend was being blowed. dont get me wrong my step daughtter is very beautiful and well developed for her age but i was shocked at what i was watching it went on for bout 2 hrs them rotating with each other i left later and took him with me and told him i knew what they was doing i asked him how it happened and he told me all the details i asked him if they was safe and used condoms he said no which dont worry me she is on the pill but i cant believe my son has turned his step sister in to his personal cum dump slut what the hell should i do now
