Milf fucking hard in hot pussy

My widowed step mum, she’s in her seventies. I’m in my fifties. I’ll visit her at least four times a week. We enjoy making love, we’ll start in missionary position. Then a few more positions, Ending with missionary. We’ll both cum multiple times. We’ve not long started a Long Term Sexual Relationship, since we’ve been making love, I’ve noticed a fabulous difference in her, she’s happier, full of energy and very enthusiastic, she says it’s all down to me! Which I tell her, it pleases me, then I know I’m doing something right. She’ll give me a cheeky little pinch, saying if you did anything wrong! I’d soon let you know.
