The wife (right) knows her husband is being unfaithful with some slut at the gym. The gym partner (left) knows he's marry and is trying to break up the marriage for weeks now. One day after workout they go to his apartment thinking his wife is at her work, she wasn't. The husband has fantasy about this and they want a piece of each other so things quickly hot physical. Who wins? 
They are both 5'7" and weight about the same.
They both start on sport bras and gym pants.
