What does that say exactly? You have pictures of a "...28 year old...."? A 28 year old what? Man? Woman? Other?
And then, "..., for you with your woman."? What does that mean?
Now my best guess is; "I want to trade some pictures I have of a nice, sexy, 28 year old woman playing with my mature cock. And I'll trade my pictures for pictures of you and your woman - even up trade."
