When step grandma asked me to oil her back, I had no idea what I was in for. She was lying there, naked and eager, her eyes gleaming with mischief. As I rubbed the oil into her skin, she moaned and squirmed, making it clear she wanted more. Before I knew it, she was begging for anal, her filthy mouth driving me wild. We ended up in a sweaty, filthy mess, both of us satisfied beyond belief.
