I slid my hand into my panties and started fingering myself while I watched my nieces head bob up and down and listened to my brothers grunts and sighs of enjoyment. Mary’s body blocked what she was doing for what felt like forever before she shifted a little and I could see her hand sliding up and down Dan’s cock. I slammed myself down on him and looked him in the eye as I rode out my orgasm. After a few more minutes of this show I was well on my way to my second orgasm when Heathers eyes rolled up into her head, her fingers running through her mother’s hair started pulling her face tighter against Heather’s pussy, and her body started trembling. Her head was steadily bobbing up and down in James’s lap and the background noise I was picking up on was slurping and sucking as she went down on her dad. Something clicked and little things started adding up that I wasn’t fully conscious of.
