I had a bbw landlady in her 50's 20 years ago, I rode her almost every night for the five years I lived there.
I was 18 then, no girlfriend and horny as hell.
My landlady was willing to provide in my needs and never refused me. I had her in every thinkable position she could handle and she loved it.

After all those years I've visited again her last month and although she's much older now I've rode her again for good times' sake. It still felt as good as then, strangely.
