Terry closed his eyes as he felt her spindly hands play with his rod with such expertise.  His wife had been rather awkward in bed, but it hadn't bothered him.  Patti was obviously in a whole 'nother league, "Oh, god, you have a great ass."  He imagined it that one time he saw her running in her short shorts.  The firmness had caught his eye immediately.  He had been so worried that his wife had caught him staring.  It all seemed so silly now, "Can I... fuck you in the ass, Patti?"  He said, cautiously.  It was something his wife had yet to have let him try.
