You catch mommy sucking the dog and she is so embarrassed... at first she tries to cover herself up and you can hear in her voice how nervous she is that you have caught her in such a naughty act. When she sees that your cock has grown hard watching her be such a kinky slut she realizes that she can relax and confesses she wants to suck you too. Sucking both your cock and dog cock together she then lets the dog fuck her and sucks you. That knot grows SO huge it makes mommy grunt and moan and gasp with pleasure and scream I am a dirty dog fucking mom. Pumping that knot as big as I can take it, I do not take your cock out of my mouth. So naughty sucking my son while I fuck that dirty dog dick
