I was going threw her letters and found one she wrote to a friend,it said,I was on a plane and a young 18yr Navy boy was sitting next to me, he was sleeping like he never slept before.He didnt know it but i had my finger in my vagina the whole trip, then when we landed i let him feel how warm my finger was.He said that i looked like a angel,and that night we made love.I was 65 at the time im sure he was no more then 18.
