Thanks for ALL your replies, really interesting reading them all, clearly I'm going ignore the ones who are saying Don't do It:)
Background
She's a Thai girl, She was a tiny 20 something when we first met, I was early 50s old fart (draw your own conclusions about my current state:) My real pleasure was with her overall company not just the sex, so my thoughts are if she's put a few pounds on and not the Miss World she use to look , I really wouldn't care that much, not sure what to expect!
Will keep you all updated, many thanks for replies so far
