Was Kay`s comment. "It`s larger than my husband`s was" said Anne. I was pleased when they said that. Then I took a chance then said that they could se...e me naked and masturbating I should see them naked. They left me for a short time and returned and said that they had given it some thought and decided that it would be safe to be naked with me because I had just masturbated and cum. They undressed in the lounge and put their clothes on a chair. What a lovely sight! Both of them had wonderful. About ten minutes later I yes at the top of my lungs, “IIIIIIIIIIIIIIIIIIIIIIII’MMMMMMMMMMMMMMMM CCCCCCCCCCCCCCCCCUUUUUUUUUUUUUUMMMMMMMMMMMMMMIIIIIIIIIINNNNNNNNNGGGGGGGGGGG!” And with a loud grunt, I deposit about six ropes of cum deep in her pussy. At the same time, she hits a cross between a high pitch squeal and yells “CCCCCCCCCCCCCCCCCCUUUUUUUUUUUUUUUUUUMMMMMMMMMMMIIIIIIIIIIIIIIIIIGGGGGGGGGGGGGGGGGGG” and I feel her juices spray my legs. Both of our breaths are short and shallow we try to. After the normal check list of questions for me she asked if I might have a little extra time to participate in a research study as I was in the target age group. The study was to see if a prostate massage might be a better way to provide erections than medicine, you know the little blue pill (there must have been an entry in the notes from before about my reaction). After qualifying me she did explain the methodology that was to be used. First, she would provide prostate exam and continue. In all of our encounters we had never tried doing it this way. We had never been able to see each other as we fucked. I knew this was going to be a turning point in our fuck-buddy relationship. I put my ankles on his shoulders and he wriggled up to me, His cock finding my tight little hole and in his fashion, ramming it to the hilt. As soon as he was balls deep in me, he began pounded away at my arse. I didn’t know if I should shout in pain or scream in pleasure. I watched his face as he fucked.
