She closed her eyes tightly as I sucked her beautiful breasts. I whispered in her ears saying, there is no difference if it is Murli or myself as we b...th are brothers and same blood. So I don’t make a difference I also told her since brother is busy I will satisfy her whenever she wants. I was also fingering her cunt vigorously.
