I had seem some men look at my grandma like that, but it was like fire the way they looked at my mom. I overheard boys and men talking about the, "bi...g tittied blonde", and realized just how special she was, and wanted to grow like her more than ever. I went to a few more track meets, and football games where she cheered, and her breasts always caught men's attention.My grandfather died when I was about 4, which besides bringing much sadness to the family, also brought many financial problems.. We all were.With nothing but my negative thoughts to entertain me, and the griminessof the day clinging to me, a shower was unavoidable. It was finally timeto face the horror show that was my body.I had seen enough naked women both professionally, and recreationally,and occasionally combining the two, to have a good idea about the normaldistribution of things, so to speak.I had a fair inkling of what to expect. Even if it was still less than aday I felt fully conscious of all the apparent. She said her husband's overseas till next weekend - hint - I kept looking at her cleavage while I was talking to her fixing her network. When I was done she thanked me and I decided this was the time to push my luck after knowing her for years.I said "No problem I enjoyed the view, that's the most I have ever seen of your boobs". She asked "Really?" all innocent. I said "Yes, I'm glad you changed for me". She stood still and looked at me all coy and I said "Let me see them properly”She said. She grasped the tops of my shoulders with both hands, lowered her pussy all the way down to my belly, and began humping me furiously....As it seemed she was getting close to an orgasm, I told her I was also getting close to cumming and was going to pull out before that happened. She just kept vigorously humping my cock, and in a moment of intimacy, bent down to kiss me hotly. I was getting ready to cum....not something I really wanted to do in another guy's wife. I told her "I'm gonna cum now".
