Seems like this hot bhabhi just had her incest sex with her devar. From the conversation and their body language, it looks clear that they used to do this quite often. She seems to feel very much comfortable standing naked in front of her brother in law. He too continues to talk to her seriously wearing a lungi alone.
She rubs her body removing any of her devar’s body hair on her. You can check out her big breasts while doing so. She did not want her husband to feel suspicious. Then, this sexy Bengali woman walks towards the mirror and adjusts her hair and face before wearing the saree.
