I'm F 29 now. When I was 8, I had a friend named Emily and almost every weekend I would spend the night at her house. Her parents were divorced and her dad had weekend custody of her and her 5 year old sister. I always noticed that her dad was super affectionate towards her and her sister, and he was always nice to me when I would spend the night. So one night when I was over, we were all watching a movie together on the couch. Emily's little sister (Gabby) was sitting on their dad's lap wearing really short fabric shorts and a tank top. Out of the corner of my eye, I noticed him running his hand up and down her little leg and to the edge of her shorts. After awhile of him doing this, she leaned back on him and I saw him lightly rubbing the outside of her shorts right on top of her little mound. He eventually got up, picked Gabby up and carried her into his bedroom. I could see that the front of his pants were sticking out (I guess his dick had gotten hard from feeling her 5 year old pussy.) After a few minutes, I could hear her gagging in his bedroom and kinda whining. I looked at Emily to see if she noticed and she just looked over and said "oh, he's just playing with her. He does it with me too sometimes." She got up and gestured to me to sneak over to the door with her, which I did. We sat outside the door quietly and listened for awhile. I could hear a sorta wet smacking and popping sound, and then Gabby gagging really hard and sighing. We both heard her dad say "That's a good girl. Try to go deeper. Mmm baby. You're gonna make all the boys at school so happy. Go again." Emily pushed the door open a crack, enough that we could look in and there was Gabby completely naked laying on her side bobbing her little head up and down on her dad's huge cock. I had never seen anyone getting a blowjob, so it was crazy watching this tiny toddler choking on a grown dick. After awhile, we went to Emily's room and not long after, I could hear Gabby whining and telling her dad no. That night, I laid there and we both listened to Gabby getting her little baby ass stretched. She was gasping and telling her dad "OWIE OWIE!", but you could tell she was just getting fucked harder by the bed squeaking. I still went over a bunch of times after that, and even watched a few times, but that's for another confession
