GRMR-149 Human Observation Watching AV with a male friend... while watching it, my pussy gets itchy! Unable to resist, my lewd female friend grabs her friend's dick

A man and a woman are friends who openly talk about dirty jokes. While drinking at the man's house, they accidentally play an adult video and the two of them watch it together. At first, they start making comments, but gradually they become silent... Perhaps thinking that they won't notice because they're concentrating on the screen, the woman starts playing with her pussy next to the man, and eventually she can't hold back and bites her friend's dick...!!
