My instructor has a huge big black cock. I knew he was packing down under when I felt him along side me. I was doing some warm-ups, and I was up against him stroking his dick pulsate like crazy. I got so horny. I had had sensual fantasies for a while now, but this solidified my feelings. I was happy as a clam being his client. I wanted him more than life itself. My holes were meant for chocolate cock. I know my husband would be so angry and fire my new trainer. I am glad I can keep this dirty little secret. I think some extra one on one lessons is due. I cannot stop perfecting these particular workouts with the help of him.
