Mario had been making money selling his semen at a local sperm bank. Apparently, one of the nurses noted the massive quantity and exceptional quality of Mario's semen. She told him that a number of wealthy, single women who used the bank's services for artificial insemination actually preferred a more "natural" approach to getting pregnant.
So the nurse asked Mario to join her in a business venture. That's how Mario became our neighbor. For the next three months each day a young or middle aged woman came to our neighbor's condo and could be seen laying nude by his pool.
Throughout the day we watched Mario fuck these women, sometimes as much as three, four, or five times in one day to ensure they received as much semen as he could produce.
They would come in three day intervals at the height of their fertile period and get Mario's "special treatment" for three days straight. He would then take two days off to regain his strength and rebuild his sperm supply.
By the end of the three months Mario had fucked at least 20 women in this manner (giving us a wonderful show each time!).
When he left he told us that of the women he fucked, about 80 percent became pregnant - highly satisfied customers to be sure!
We are looking forward to Mario's return this summer. My wife has reached menopause, is not worried about becoming pregnant, and is thinking about asking Mario to service her as well!
