Works on his butt every day.  Lunges, Squats, Rows, all to tighten and firm.  It works to attract alpha males,  But the real reward is when a big, fat cock plunges between his cheeks and deep into his hole.  The feeling of a man’s meat stretching his hole and deepening his cunt.  

When the man using him to get off says “That is one fine ass”, it is all worth it.
