Oiling up my stepmom

My stepmom needs my help with a very special task today, and boy am I happy to be of assistance. She wants me to put lotion on her back so she can get an even tan. Before I start rubbing her down, she takes her top off so she will not get any tan lines. Holy moly, her tits are huge and sexy! I can barely contain myself. Maybe my stepmom will like my own bottle of cum.
